RETURN VALUES

	Returns an ODBC result identifier or FALSE on failure.

	The result set has the following columns:

	      oPKTABLE_QUALIFIER

	      oPKTABLE_OWNER

	      oPKTABLE_NAME

	      oPKCOLUMN_NAME

	      oFKTABLE_QUALIFIER

	      oFKTABLE_OWNER

	      oFKTABLE_NAME

	      oFKCOLUMN_NAME

	      oKEY_SEQ

	      oUPDATE_RULE

	      oDELETE_RULE

	      oFK_NAME

	If  $pk_table contains a table name, odbc_foreignkeys(3) 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(3) 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(3) 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.
