Descriptionresource odbc_foreignkeys ( resource connection_id, string pk_qualifier, string pk_owner, string pk_table, string fk_qualifier, string fk_owner, string fk_table ) odbc_foreignkeys() retrieves information about
foreign keys. Returns an ODBC result identifier or
FALSE on failure.
The result set has the following columns:
PKTABLE_QUALIFIER PKTABLE_OWNER PKTABLE_NAME PKCOLUMN_NAME FKTABLE_QUALIFIER FKTABLE_OWNER FKTABLE_NAME FKCOLUMN_NAME KEY_SEQ UPDATE_RULE DELETE_RULE FK_NAME PK_NAME
If pk_table contains a table name,
odbc_foreignkeys() returns a result set
containing the primary key of the specified table and all of the
foreign keys that refer to it.
If fk_table contains a table name,
odbc_foreignkeys() returns a result set
containing all of the foreign keys in the specified table and the
primary keys (in other tables) to which they refer.
If both pk_table and
fk_table contain table names,
odbc_foreignkeys() returns the foreign keys in
the table specified in fk_table that refer
to the primary key of the table specified in
pk_table. This should be one key at most.
