maxdb_stmt_errno -- maxdb_stmt->errno — Returns the error code for the most recent statement call
过程化风格
面向对象风格
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.
Note:
For possible error codes see documentation of SQLDBC: » http://maxdb.sap.com/documentation/.
An error code value. Zero means no error occurred.
Example #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();
?>
Example #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);
?>
以上例程的输出类似于：
Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...> Error: -4004.
