maxdb_stmt_errno (PECL) maxdb_stmt_errno (no version information, might be only in CVS) maxdb_stmt->errno -- Returns the error code for the most recent statement call DescriptionProcedural style : int maxdb_stmt_errno ( resource stmt ) Object oriented style (property): class stmt { int errno }
For the statement specified by stmt, maxdb_stmt_errno()
returns the error code for the most recently invoked statement function that can succeed or fail.
Замечание:
For possible error codes see documentation of SQLDBC:
http://dev.mysql.com/doc/maxdb/.
Return values
An error code value. Zero means no error occurred.
ExampleПример 1. Object oriented style
<?php /* Open a connection */ $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); }
$maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city"); $maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city");
$query = "SELECT name, zip FROM temp.mycity ORDER BY name"; if ($stmt = $maxdb->prepare($query)) {
/* drop table */ $maxdb->query("DROP TABLE temp.mycity");
/* execute query */ $stmt->execute();
printf("Error: %d.\n", $stmt->errno);
/* close statement */ $stmt->close(); }
/* close connection */ $maxdb->close(); ?>

Пример 2. Procedural style
<?php /* Open a connection */ $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); }
maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city"); maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city");
$query = "SELECT name, zip FROM temp.mycity ORDER BY name"; if ($stmt = maxdb_prepare($link, $query)) {
/* drop table */ maxdb_query($link, "DROP TABLE temp.mycity");
/* execute query */ maxdb_stmt_execute($stmt);
printf("Error: %d.\n", maxdb_stmt_errno($stmt));
/* close statement */ maxdb_stmt_close($stmt); }
/* close connection */ maxdb_close($link); ?>

The above examples would produce the following output:
Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...>
Error: -4004. |
