                               odbc_foreignkeys

   (PHP 4 )
   odbc_foreignkeys --  Returns a list of foreign keys in the specified
   table or a list of foreign keys in other tables that refer to the
   primary key in the specified table

Description

   resource 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.
