戻り値

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.
