( mysqli_stmt $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. For a list of possible values, see

Note that not all MySQL errors are yet mapped to SQLSTATE's. The value
HY000(general error) is used for unmapped errors.
范例
Example #1 面向对象风格
<?php/* Open a connection */$mysqli = new mysqli("localhost", "my_user", "my_password", "world");/* check connection */if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit();}$mysqli->query("CREATE TABLE myCountry LIKE Country");$mysqli->query("INSERT INTO myCountry SELECT * FROM Country");$query = "SELECT Name, Code FROM myCountry ORDER BY Name";if ($stmt = $mysqli->prepare($query)) { /* drop table */ $mysqli->query("DROP TABLE myCountry"); /* execute query */ $stmt->execute(); printf("Error: %s.\n", $stmt->sqlstate); /* close statement */ $stmt->close();}/* close connection */$mysqli->close();?>
Example #2 过程化风格
<?php/* Open a connection */$link = mysqli_connect("localhost", "my_user", "my_password", "world");/* check connection */if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit();}mysqli_query($link, "CREATE TABLE myCountry LIKE Country");mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");$query = "SELECT Name, Code FROM myCountry ORDER BY Name";if ($stmt = mysqli_prepare($link, $query)) { /* drop table */ mysqli_query($link, "DROP TABLE myCountry"); /* execute query */ mysqli_stmt_execute($stmt); printf("Error: %s.\n", mysqli_stmt_sqlstate($stmt)); /* close statement */ mysqli_stmt_close($stmt);}/* close connection */mysqli_close($link);?>
以上例程会输出：
Error: 42S02.
