on error

Returns:

Object relating to oid

Throws: SQLException

on error

public int store(Object o) throws SQLException

This stores an object into a table, returning it's OID.

If the object has an int called OID, and it is > 0, then

that value is used for the OID, and the table will be updated. If the

value of OID is 0, then a new row will be created, and the value of

OID will be set in the object. This enables an object's value in the

database to be updateable. If the object has no int called OID, then

the object is stored. However if the object is later retrieved,

amended and stored again, it's new state will be appended to the

table, and will not overwrite the old entries.

Parameters:

o - Object to store (must implement Serializable)

Returns:

oid of stored object

Throws: SQLException

on error

public static void create(org.postgresql.Connection con,

Object o) throws SQLException

This method is not used by the driver, but it creates a

table, given a Serializable Java Object. It should be used before

serializing any objects.

Parameters:

c - Connection to database

o - Object to base table on

Throws: SQLException

on error

public static void create(Connection con,

Class c) throws SQLException

This method is not used by the driver, but it creates a

public PGmoney()

public void setValue(String s) throws SQLException

Parameters:
