Interface RowSet

All Superinterfaces:: java.sql.ResultSet

public interfaceRowSet
extends java.sql.ResultSet

The RowSet interface adds support to the JDBC API for the JavaBeans(TM) component model. A rowset can be used as a JavaBean in a visual Bean development environment. A RowSet can be created and configured at design time and executed at runtime. The RowSet interface provides a set of JavaBeans properties that allow a RowSet instance to be configured to connect to a JDBC data source and read some data from the data source. A group of setXXX() methods provide a way to pass input parameters to a rowset. The RowSet interface supports JavaBeans events, allowing other components in an application to be notified when an important event on a rowset occurs, such as a change in its value.

The RowSet interface is unique in that it is intended to be implemented using the rest of the JDBC(TM) API. In other words, a RowSet implementation is a layer of software that executes "on top" of a JDBC driver. Implementations of the RowSet interface can be provided by anyone, including JDBC driver vendors who want to provide a RowSet implementation as part of their JDBC products.

Rowsets are easy to use. The RowSet interface extends the standard java.sql.ResultSet interface. The RowSetMetaData interface extends the java.sql.ResultSetMetaData interface. Thus, developers familiar with the JDBC API will have to learn a minimal number of new APIs to use rowsets. In addition, third-party software tools that work with JDBC ResultSets will also easily be made to work with rowsets.

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; sqlType - SQL type code defined by java.sql.Types
Throws:: java.sql.SQLException - if a database-access error occurs.

setNull

public voidsetNull(int paramIndex,                    int sqlType,                    java.lang.String typeName)             throws java.sql.SQLException

JDBC 2.0 Set a parameter to SQL NULL. This version of setNull should be used for user-named types and REF type parameters. Examples of user-named types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully qualified SQL type name when specifying a NULL user-named or REF parameter. In the case of a user-named type the name is the type name of the parameter itself. For a REF parameter the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-named and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-named or REF type then the typeName is ignored.

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; sqlType - a value from java.sql.Types; typeName - the fully qualified name of a SQL user-named type, ignored if the parameter is not a user-named type or REF

Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.

The given Java object will be converted to the targetSqlType before being sent to the database. If the object is of a class implementing SQLData, the rowset should call its method writeSQL() to write it to the SQL data stream. else If the object is of a class implementing Ref, Blob, Clob, Struct, or Array then pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass datatabase- specific abstract data types.

Parameters:: parameterIndex - The first parameter is 1, the second is 2, ...; x - The object containing the input parameter value; targetSqlType - The SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.; scale - For java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types this is the number of digits after the decimal. For all other types this value will be ignored,
Throws:: java.sql.SQLException - if a database-access error occurs.

Set the value of a parameter using an object; use the java.lang equivalent objects for integral values.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument java object will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass datatabase specific abstract data types, by using a Driver specific Java type. If the object is of a class implementing SQLData, the rowset should call its method writeSQL() to write it to the SQL data stream. else If the object is of a class implementing Ref, Blob, Clob, Struct, or Array then pass it to the database as a value of the corresponding SQL type. Raise an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of those interfaces.

Parameters:: parameterIndex - The first parameter is 1, the second is 2, ...; x - The object containing the input parameter value
Throws:: java.sql.SQLException - if a database-access error occurs.

setRef

public voidsetRef(int i,                   java.sql.Ref x)            throws java.sql.SQLException

Set a REF(<structured-type>) parameter.

Parameters:: i - the first parameter is 1, the second is 2, ...; x - an object representing data of an SQL REF Type

setBlob

public voidsetBlob(int i,                    java.sql.Blob x)             throws java.sql.SQLException

Set a BLOB parameter.

Parameters:: i - the first parameter is 1, the second is 2, ...; x - an object representing a BLOB

setClob

public voidsetClob(int i,                    java.sql.Clob x)             throws java.sql.SQLException

Set a CLOB parameter.

Parameters:: i - the first parameter is 1, the second is 2, ...; x - an object representing a CLOB

setArray

public voidsetArray(int i,                     java.sql.Array x)              throws java.sql.SQLException

Set an Array parameter.

Parameters:: i - the first parameter is 1, the second is 2, ...; x - an object representing an SQL array

setDate

public voidsetDate(int parameterIndex,                    java.sql.Date x,                    java.util.Calendar cal)             throws java.sql.SQLException

Set a parameter to a java.sql.Date value. The driver converts this to a SQL DATE value when it sends it to the database.

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the parameter value
Throws:: java.sql.SQLException - if a database-access error occurs.

setTime

public voidsetTime(int parameterIndex,                    java.sql.Time x,                    java.util.Calendar cal)             throws java.sql.SQLException

Set a parameter to a java.sql.Time value. The driver converts this to a SQL TIME value when it sends it to the database.

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the parameter value
Throws:: java.sql.SQLException - if a database-access error occurs.

setTimestamp

public voidsetTimestamp(int parameterIndex,                         java.sql.Timestamp x,                         java.util.Calendar cal)                  throws java.sql.SQLException

Set a parameter to a java.sql.Timestamp value. The driver converts this to a SQL TIMESTAMP value when it sends it to the database.

Parameters:: parameterIndex - the first parameter is 1, the second is 2, ...; x - the parameter value
Throws:: java.sql.SQLException - if a database-access error occurs.

clearParameters

public voidclearParameters()                     throws java.sql.SQLException

In general, parameter values remain in force for repeated use of a RowSet. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling clearParameters.

Throws:: java.sql.SQLException - if a database-access error occurs.

execute

public voidexecute()             throws java.sql.SQLException

Fills the rowset with data. Execute() may use the following properties: url, data source name, user name, password, transaction isolation, and type map to create a connection for reading data. Execute may use the following properties to create a statement to execute a command: command, read only, maximum field size, maximum rows, escape processing, and query timeout. If the required properties have not been set, an exception is thrown. If successful, the current contents of the rowset are discarded and the rowset's metadata is also (re)set. If there are outstanding updates, they are ignored.

Throws:: java.sql.SQLException - if a database-access error occurs.

addRowSetListener

public voidaddRowSetListener(RowSetListener listener)

RowSet listener registration. Listeners are notified when an event occurs.

Parameters:: listener - an event listener

removeRowSetListener

public voidremoveRowSetListener(RowSetListener listener)

RowSet listener deregistration.

Parameters:: listener - an event listener
