(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.
