(PHP 4 )
odbc_foreignkeys() retrieves
information about foreign keys. Returns an ODBC result
identifier or FALSE on
failure.
The result set has the following columns:
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.
