pg_result_error_field

Returns an individual field of an error report. (PHP 5 >= 5.1.0)
string pg_result_error_field ( resource result, int fieldcode )

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

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

A PostgreSQL query result resource from a previously executed statement.

fieldcode

Possible fieldcode 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.
