Code Examples

pg_result_error_field( PgSql\Result$result, int$field_code ): string|false|null

pg_result_error_field returns one of the detailed error message fields associated with result instance. It is only available against a PostgreSQL 7.4 or above server. The error field is specified by the field_code.

Because pg_query and pg_query_params return false if the query fails, you must use pg_send_query and pg_get_result to get the result handle.

If you need to get additional error information from failed pg_query queries, use pg_set_error_verbosity and pg_last_error and then parse the result.

Parameters

result

An PgSql\Result instance, returned by pg_query, pg_query_params or pg_execute(among others).

field_code

Possible field_code values are: PGSQL_DIAG_SEVERITY, PGSQL_DIAG_SQLSTATE, PGSQL_DIAG_MESSAGE_PRIMARY, PGSQL_DIAG_MESSAGE_DETAIL, PGSQL_DIAG_MESSAGE_HINT, PGSQL_DIAG_STATEMENT_POSITION, PGSQL_DIAG_INTERNAL_POSITION (PostgreSQL 8.0+ only), PGSQL_DIAG_INTERNAL_QUERY (PostgreSQL 8.0+ only), PGSQL_DIAG_CONTEXT, PGSQL_DIAG_SOURCE_FILE, PGSQL_DIAG_SOURCE_LINE or PGSQL_DIAG_SOURCE_FUNCTION.

Return Values

A string containing the contents of the error field, null if the field does not exist or false on failure.
