(PHP 5)

pg_result_error_field -- Returns an individual field of an error report.

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.

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.

Examples
