mysqli_stmt::$error -- mysqli_stmt_error — Returns a string description for last statement error
面向对象风格
过程化风格
$stmt
)Returns a string containing the error message for the most recently invoked statement function that can succeed or fail.
stmt
仅以过程化样式:由 mysqli_stmt_init() 返回的 statement 标识。
A string that describes the error. An empty string if no error occurred.
Example #1 面向对象风格
<?php
$mysqli = new mysqli ( "localhost" , "my_user" , "my_password" , "world" );
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 )) {
$mysqli -> query ( "DROP TABLE myCountry" );
$stmt -> execute ();
printf ( "Error: %s.\n" , $stmt -> error );
$stmt -> close ();
}
$mysqli -> close ();
?>
Example #2 过程化风格
<?php
$link = mysqli_connect ( "localhost" , "my_user" , "my_password" , "world" );
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 )) {
mysqli_query ( $link , "DROP TABLE myCountry" );
mysqli_stmt_execute ( $stmt );
printf ( "Error: %s.\n" , mysqli_stmt_error ( $stmt ));
mysqli_stmt_close ( $stmt );
}
mysqli_close ( $link );
?>
以上例程会输出:
Error: Table 'world.myCountry' doesn't exist.
