Description
int odbc_foreignkeys (int 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.
