getExportedKeys(String catalog, String schema, String table)

Syntax:

ResultSet getExportedKeys(String catalog,
                          String schema,
                          String table)
                          throws SQLException

Description:

Retrieves a description of the foreign key columns that reference the given table's primary key columns (the foreign keys exported by a table). They are ordered by FKTABLE_CAT, FKTABLE_SCHEM, FKTABLE_NAME, and KEY_SEQ.

Each foreign key column description has the following columns:

PKTABLE_CAT	String	parent key table catalog (may be null)
PKTABLE_SCHEM	String	parent key table schema (may be null)
PKTABLE_NAME	String	parent key table name
PKCOLUMN_NAME	String	parent key column name
FKTABLE_CAT	String	foreign key table catalog (may be null) being exported (may be null)
FKTABLE_SCHEM	String	foreign key table schema (may be null) being exported (may be null)
FKTABLE_NAME	String	foreign key table name being exported
FKCOLUMN_NAME	String	foreign key column name being exported
KEY_SEQ	short	sequence number within foreign key( a value of 1 represents the first column of the foreign key, a value of 2 would represent the second column within the foreign key).
UPDATE_RULE	short	What happens to foreign key when parent key is updated: importedNoAction - do not allow update of parent key if it has been imported importedKeyCascade - change imported key to agree with parent key update importedKeySetNull - change imported key to NULL if its parent key has been updated importedKeySetDefault - change imported key to default values if its parent key has been updated importedKeyRestrict - same as importedKeyNoAction (for ODBC 2.x compatibility)
DELETE_RULE	short	What happens to the foreign key when parent key is deleted. importedKeyNoAction - do not allow delete of parent key if it has been imported importedKeyCascade - delete rows that import a deleted key importedKeySetNull - change imported key to NULL if its primary key has been deleted importedKeyRestrict - same as importedKeyNoAction (for ODBC 2.x compatibility)
FK_NAME	String	foreign key name (may be null)
PK_NAME	String	parent key name (may be null)
DEFERABILITY	short	can the evaluation of foreign key constraints be deferred until commit importedKeyInitiallyDeferred - see SQL92 for definition importedKeyInitiallyImmediate - see SQL92 for definition importedKeyNotDeferrable - see SQL92 for definition

Parameters:

catalog - a catalog name; must match the catalog name as it is stored in this database; "" retrieves those without a catalog; null means that the catalog name should not be used to narrow the search

schema - a schema name; must match the schema name as it is stored in the database; "" retrieves those without a schema; null means that the schema name should not be used to narrow the search

table - a table name; must match the table name as it is stored in this database

Returns:

a ResultSet object in which each row is a foreign key column description

Throws:

SQLException - if a database access error occurs
