maxdb_stmt_sqlstate

(PECL maxdb >= 1.0)

maxdb_stmt_sqlstate — Returns SQLSTATE error from previous statement operation

说明

maxdb_stmt_sqlstate ( resource $stmt ) : string

Returns a string containing the SQLSTATE error code for the most recently invoked prepared statement function that can succeed or fail. The error code consists of five characters. '00000' means no error. The values are specified by ANSI SQL and ODBC.

Note:

Note that not all MaxDB errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors.

返回值

Returns a string containing the SQLSTATE error code for the last error. The error code consists of five characters. '00000' means no error.

范例

Example #1 面向对象风格

<?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: %s.\n", $stmt->sqlstate);

   /* close statement */
   $stmt->close();
}

/* close connection */
$maxdb->close();
?>

Example #2 过程化风格

<?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: %s.\n", maxdb_stmt_sqlstate($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: 42000.
