过程化风格

string maxdb_sqlstate ( resource $link )

面向对象风格

string $maxdb->sqlstate;

Returns a string containing the SQLSTATE error code for the last error. 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
$maxdb 
= new maxdb("localhost""MONA""RED""DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

/* Table City already exists, so we should get an error */
if (!$maxdb->query("CREATE TABLE hotel.city (ID INT, Name VARCHAR(30))")) {
   
printf("Error - SQLSTATE %s.\n"$maxdb->sqlstate);
}

$maxdb->close();
?>

Example #2 过程化风格

<?php
$link 
maxdb_connect("localhost""MONA""RED""DEMODB");

/* check connection */
if (maxdb_connect_errno()) {
   
printf("Connect failed: %s\n"maxdb_connect_error());
   exit();
}

/* Table City already exists, so we should get an error */
if (!maxdb_query($link"CREATE TABLE hotel.city (ID INT, Name VARCHAR(30))")) {
   
printf("Error - SQLSTATE %s.\n"maxdb_sqlstate($link));
}

maxdb_close($link);
?>

以上例程的输出类似于:

Warning: maxdb_query(): -6000 POS(20) Duplicate table name:CITY [I6000] <...>
Error - SQLSTATE I6000.
