A table of data representing a database result set, which is usually generated by executing a statement that queries the database.
AResultSet object maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. Thenext method moves the cursor to the next row, and because it returnsfalse when there are no more rows in theResultSet object, it can be used in awhile loop to iterate through the result set.
A defaultResultSet object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produceResultSet objects that are scrollable and/or updatable. The following code fragment, in whichcon is a validConnection object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. SeeResultSet fields for other options.
```
       Statement stmt = con.createStatement(                                      ResultSet.TYPE_SCROLL_INSENSITIVE,                                      ResultSet.CONCUR_UPDATABLE);       ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");       // rs will be scrollable, will not show changes made by others,       // and will be updatable
```
TheResultSet interface providesgetter methods (getBoolean,getLong, and so on) for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.
For the getter methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the getter method and returns a suitable Java value. The JDBC specification has a table showing the allowable mappings from SQL types to Java types that can be used by theResultSet getter methods.
Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQLAS clause.
A set of updater methods were added to this interface in the JDBC 2.0 API (Java 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.
The updater methods may be used in two ways:
1. to update a column value in the current row. In a scrollableResultSet object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates theNAME column in the fifth row of theResultSet objectrs and then uses the methodupdateRow to update the data source table from whichrs was derived.
```
       rs.absolute(5); // moves the cursor to the fifth row of rs       rs.updateString("NAME", "AINSWORTH"); // updates the          //NAME column of row 5 to beAINSWORTH       rs.updateRow(); // updates the row in the data source
```
2. to insert column values into the insert row. An updatableResultSet object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it intors and into the data source table using the methodinsertRow.
```
       rs.moveToInsertRow(); // moves cursor to the insert row       rs.updateString(1, "AINSWORTH"); // updates the          // first column of the insert row to beAINSWORTH       rs.updateInt(2,35); // updates the second column to be35       rs.updateBoolean(3, true); // updates the third column totrue       rs.insertRow();       rs.moveToCurrentRow();
```
AResultSet object is automatically closed when theStatement object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.
The number, types and properties of aResultSet object's columns are provided by theResultSetMetaData object returned by theResultSet.getMetaData method.

- Method Detail
  - next
```
boolean next()             throwsSQLException
```
    Moves the cursor froward one row from its current position. AResultSet cursor is initially positioned before the first row; the first call to the methodnext makes the first row the current row; the second call makes the second row the current row, and so on.
    When a call to thenext method returnsfalse, the cursor is positioned after the last row. Any invocation of aResultSet method which requires a current row will result in aSQLException being thrown. If the result set type isTYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will returnfalse or throw anSQLException on a subsequent call tonext.
    If an input stream is open for the current row, a call to the methodnext will implicitly close it. AResultSet object's warning chain is cleared when a new row is read.
    Returns:
    true if the new current row is valid;false if there are no more rows
    Throws:
    SQLException - if a database access error occurs or this method is called on a closed result set
  - close
```
void close()           throwsSQLException
```
    Releases thisResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.
    The closing of aResultSet object doesnot close theBlob,Clob orNClob objects created by theResultSet.Blob,Clob orNClob objects remain valid for at least the duration of the transaction in which they are creataed, unless theirfree method is invoked.
    When aResultSet is closed, anyResultSetMetaData instances that were created by calling thegetMetaData method remain accessible.
    Note: AResultSet object is automatically closed by theStatement object that generated it when thatStatement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.
    Calling the methodclose on aResultSet object that is already closed is a no-op.

    Retrieves the value of the designated column in the current row of thisResultSet object as a stream of uninterpretedbytes. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving largeLONGVARBINARY values.
    Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return0 when the methodavailable is called whether there is data available or not.
    Parameters:
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    Returns:
    a Java input stream that delivers the database column value as a stream of uninterpreted bytes; if the value is SQLNULL, the result isnull
    Throws:
    SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set
  - getWarnings
```
SQLWarning getWarnings()                       throwsSQLException
```
    Retrieves the first warning reported by calls on thisResultSet object. Subsequent warnings on thisResultSet object will be chained to theSQLWarning object that this method returns.
    The warning chain is automatically cleared each time a new row is read. This method may not be called on aResultSet object that has been closed; doing so will cause anSQLException to be thrown.
    Note: This warning chain only covers warnings caused byResultSet methods. Any warning caused byStatement methods (such as reading OUT parameters) will be chained on theStatement object.
    Returns:
    the firstSQLWarning object reported ornull if there are none
    Throws:
    SQLException - if a database access error occurs or this method is called on a closed result set
  - clearWarnings
```
void clearWarnings()                   throwsSQLException
```
    Clears all warnings reported on thisResultSet object. After this method is called, the methodgetWarnings returnsnull until a new warning is reported for thisResultSet object.
    Throws:
    SQLException - if a database access error occurs or this method is called on a closed result set
  - getCursorName
```
String getCursorName()                     throwsSQLException
```
    Retrieves the name of the SQL cursor used by thisResultSet object.
    In SQL, a result table is retrieved through a cursor that is named. The current row of a result set can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor'sSELECT statement should be of the formSELECT FOR UPDATE. IfFOR UPDATE is omitted, the positioned updates may fail.
    The JDBC API supports this SQL feature by providing the name of the SQL cursor used by aResultSet object. The current row of aResultSet object is also the current row of this SQL cursor.
    Returns:
    the SQL name for thisResultSet object's cursor
    Throws:
    SQLException - if a database access error occurs or this method is called on a closed result set
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
  - getMetaData
```
ResultSetMetaData getMetaData()                              throwsSQLException
```
    Retrieves the number, types and properties of thisResultSet object's columns.
    Returns:
    the description of thisResultSet object's columns
    Throws:
    SQLException - if a database access error occurs or this method is called on a closed result set
  - getObject
```
Object getObject(int columnIndex)                 throwsSQLException
```
    Gets the value of the designated column in the current row of thisResultSet object as anObject in the Java programming language.
    This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQLNULL, the driver returns a Javanull.
    This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of methodgetObject is extended to materialize data of SQL user-defined types.
    IfConnection.getTypeMap does not throw aSQLFeatureNotSupportedException, then when a column contains a structured or distinct value, the behavior of this method is as if it were a call to:getObject(columnIndex, this.getStatement().getConnection().getTypeMap()). IfConnection.getTypeMap does throw aSQLFeatureNotSupportedException, then structured values are not supported, and distinct values are mapped to the default Java class as determined by the underlying SQL type of the DISTINCT type.
    Parameters:
    columnIndex - the first column is 1, the second is 2, ...
    Returns:
    ajava.lang.Object holding the column value
    Throws:
    SQLException - if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set
  - getObject

  - absolute
```
boolean absolute(int row)                 throwsSQLException
```
    Moves the cursor to the given row number in thisResultSet object.
    If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.
    If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the methodabsolute(-1) positions the cursor on the last row; calling the methodabsolute(-2) moves the cursor to the next-to-last row, and so on.
    If the row number specified is zero, the cursor is moved to before the first row.
    An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.
    Note: Callingabsolute(1) is the same as callingfirst(). Callingabsolute(-1) is the same as callinglast().
    Parameters:
    row - the number of the row to which the cursor should move. A value of zero indicates that the cursor will be positioned before the first row; a positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
    Returns:
    true if the cursor is moved to a position in thisResultSet object;false if the cursor is before the first row or after the last row
    Throws:
    SQLException - if a database access error occurs; this method is called on a closed result set or the result set type isTYPE_FORWARD_ONLY
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    Since:
    1.2
  - relative
```
boolean relative(int rows)                 throwsSQLException
```
    Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Callingrelative(0) is valid, but does not change the cursor position.
    Note: Calling the methodrelative(1) is identical to calling the methodnext() and calling the methodrelative(-1) is identical to calling the methodprevious().
    Parameters:
    rows - anint specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward
    Returns:
    true if the cursor is on a row;false otherwise
    Throws:
    SQLException - if a database access error occurs; this method is called on a closed result set or the result set type isTYPE_FORWARD_ONLY
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method

    1.2
  - previous
```
boolean previous()                 throwsSQLException
```
    Moves the cursor to the previous row in thisResultSet object.
    When a call to theprevious method returnsfalse, the cursor is positioned before the first row. Any invocation of aResultSet method which requires a current row will result in aSQLException being thrown.
    If an input stream is open for the current row, a call to the methodprevious will implicitly close it. AResultSet object's warning change is cleared when a new row is read.
    Returns:
    true if the cursor is now positioned on a valid row;false if the cursor is positioned before the first row
    Throws:
    SQLException - if a database access error occurs; this method is called on a closed result set or the result set type isTYPE_FORWARD_ONLY

```
    Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed for thisResultSet object. If the fetch size specified is zero, the JDBC driver ignores the value and is free to make its own best guess as to what the fetch size should be. The default value is set by theStatement object that created the result set. The fetch size may be changed at any time.
    Parameters:
    rows - the number of rows to fetch

If these conditions are not true the driver will generate aSQLException when the statement is executed.
    Parameters:
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    x - the new column value
    scaleOrLength - for an object ofjava.math.BigDecimal , this is the number of digits after the decimal point. For Java Object typesInputStream andReader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
    Throws:
    SQLException - if the columnLabel is not valid; if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY or this method is called on a closed result set
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    Since:

  - updateObject
```
void updateObject(String columnLabel,Object x)                  throwsSQLException
```
    Updates the designated column with anObject value. The updater methods are used to update column values in the current row or the insert row. The updater methods do not update the underlying database; instead theupdateRow orinsertRow methods are called to update the database.
    Parameters:
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    x - the new column value
    Throws:
    SQLException - if the columnLabel is not valid; if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY or this method is called on a closed result set
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method

    1.2
  - insertRow
```
void insertRow()               throwsSQLException
```
    Inserts the contents of the insert row into thisResultSet object and into the database. The cursor must be on the insert row when this method is called.
    Throws:
    SQLException - if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY, this method is called on a closed result set, if this method is called when the cursor is not on the insert row, or if not all of non-nullable columns in the insert row have been given a non-null value
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    Since:
    1.2
  - updateRow
```
void updateRow()               throwsSQLException
```
    Updates the underlying database with the new contents of the current row of thisResultSet object. This method cannot be called when the cursor is on the insert row.
    Throws:
    SQLException - if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY; this method is called on a closed result set or if this method is called when the cursor is on the insert row
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    Since:
    1.2
  - deleteRow
```
void deleteRow()               throwsSQLException
```
    Deletes the current row from thisResultSet object and from the underlying database. This method cannot be called when the cursor is on the insert row.
    Throws:
    SQLException - if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY; this method is called on a closed result set or if this method is called when the cursor is on the insert row
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    Since:
    1.2
  - refreshRow
```
void refreshRow()                throwsSQLException
```
    Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.
    TherefreshRow method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to callrefreshRow when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.
    All values are refetched subject to the transaction isolation level and cursor sensitivity. IfrefreshRow is called after calling an updater method, but before calling the methodupdateRow, then the updates made to the row are lost. Calling the methodrefreshRow frequently will likely slow performance.
    Throws:
    SQLException - if a database access error occurs; this method is called on a closed result set; the result set type isTYPE_FORWARD_ONLY or if this method is called when the cursor is on the insert row
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method or this method is not supported for the specified result set type and result set concurrency.
    Since:
    1.2
  - cancelRowUpdates
```
void cancelRowUpdates()                      throwsSQLException
```
    Cancels the updates made to the current row in thisResultSet object. This method may be called after calling an updater method(s) and before calling the methodupdateRow to roll back the updates made to a row. If no updates have been made orupdateRow has already been called, this method has no effect.
    Throws:
    SQLException - if a database access error occurs; this method is called on a closed result set; the result set concurrency isCONCUR_READ_ONLY or if this method is called when the cursor is on the insert row
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    Since:
    1.2
  - moveToInsertRow
```
void moveToInsertRow()                     throwsSQLException
```
    Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updater methods prior to inserting the row into the result set. Only the updater, getter, andinsertRow methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before callinginsertRow. An updater method must be called before a getter method can be called on a column value.
    Throws:
    SQLException - if a database access error occurs; this method is called on a closed result set or the result set concurrency isCONCUR_READ_ONLY
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method

```
void updateClob(String columnLabel,Reader reader,              long length)                throwsSQLException
```
    Updates the designated column using the givenReader object, which is the given number of characters long. When a very large UNICODE value is input to aLONGVARCHAR parameter, it may be more practical to send it via ajava.io.Reader object. The JDBC driver will do any necessary conversion from UNICODE to the database char format.
    The updater methods are used to update column values in the current row or the insert row. The updater methods do not update the underlying database; instead theupdateRow orinsertRow methods are called to update the database.
    Parameters:
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
    reader - An object that contains the data to set the parameter value to.
    length - the number of characters in the parameter data.
    Throws:
    SQLException - if the columnLabel is not valid; if a database access error occurs; the result set concurrency isCONCUR_READ_ONLY or this method is called on a closed result set
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
