pg_result_error_field (PHP 5 >= 5.1.0RC1) pg_result_error_field -- Returns an individual field of an error report. Descriptionstring 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 ValuesA string containing the contents of the error field, NULL if the field does not exist or FALSE
on failure. Examples

$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
