(no version information, might be only in CVS)

pg_result_error_field -- Get error message field associated with result

## Description

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.

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.

## Exemples

Exemple 1. pg_result_error_field() example
`<?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); if (!pg_connection_busy($dbconn)) { pg_send_query($dbconn, "select * from doesnotexist;"); } $res1 = pg_get_result($dbconn); echo pg_result_error_field($res1, PGSQL_DIAG_SQLSTATE); ?>`
