(PHP 4, PHP 5)

odbc_foreignkeys — Retrieves a list of foreign keys

### 설명

resource odbc_foreignkeys ( resource `$connection_id` , string `$pk_qualifier` , string `$pk_owner` , string `$pk_table` , string `$fk_qualifier` , string `$fk_owner` , string `$fk_table` )

Retrieves 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

### 인수

`connection_id`

  ODBC 접속 식별자. odbc_connect()를 참고하십시오.

`pk_qualifier`

  The primary key qualifier.

`pk_owner`

  The primary key owner.

`pk_table`

  The primary key table.

`fk_qualifier`

  The foreign key qualifier.

`fk_owner`

  The foreign key owner.

`fk_table`

  The foreign key table.

### 반환값

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.
