pg_result_error_field(PHP 5 >= 5.1.0) pg_result_error_field — Returns an individual field of an error report. 说明
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. 参数
返回值A string containing the contents of the error field, NULL if the field does not exist or FALSE on failure. 范例
