[英]Mysqli transaction fail to rollback when insert is failed
I have 3 databases, where I need to create database A, then database B, then create the linking database A_B.我有 3 个数据库,我需要在其中创建数据库 A,然后是数据库 B,然后创建链接数据库 A_B。
I use mysqli transactions in PHP, there is a weird case(this is the first time i use php transactions), where it never rollback when it fails, case like database A fail to insert, but B still created.我在PHP中使用mysqli事务,有一个奇怪的情况(这是我第一次使用php事务),它在失败时永远不会回滚,例如数据库A插入失败,但B仍然创建。 and A_B created incorrectly.
和 A_B 创建不正确。
mysqli_begin_transaction($link);
try{
$sql = "INSERT INTO A (
....)
VALUES
(?, ?, ?, ?, ?, ?, ?, ?, ?,?,?,?,?);";
$stmt = mysqli_prepare($link,$sql);
mysqli_stmt_bind_param($stmt,"sssssssssssss",
....
);
mysqli_stmt_execute($stmt);
$param_new_A_Rec = mysqli_insert_id($link);
for($i = 0; $i < $tot; $i++){
$sql = "INSERT INTO B (..)
VALUES
(?, ?, ?, ?, ?, ?, ?, ?, ?,?,?,?);";
$stmt = mysqli_prepare($link,$sql);
mysqli_stmt_bind_param($stmt,"ssssssssssss",
...
);
mysqli_stmt_execute($stmt);
$param_new_B_Rec = mysqli_insert_id($link);
$sql = "INSERT INTO A_B (
param_new_A_Rec,
param_new_B_Rec,
....
(?,?,?,?,?,?);";
$stmt = mysqli_prepare($link,$sql);
mysqli_stmt_bind_param($stmt,"ssssss",
....
);
mysqli_stmt_execute($stmt);
}
mysqli_commit($link);
}catch (mysqli_sql_exception $exception) {
mysqli_rollback($link);
throw $exception;
}
Why if A failed, it never hit the rollback() and it created the incorrect A_B and B data?为什么如果 A 失败了,它永远不会命中 rollback() 并且它创建了不正确的 A_B 和 B 数据? Did I miss anything here?
我在这里错过了什么吗? any help would be greatly appreciated!
任何帮助将不胜感激!
In fact, I need to add this事实上,我需要添加这个
"mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);" "mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);"
Now it is catching the invalid use case:现在它正在捕获无效的用例:
PHP Fatal error: Uncaught mysqli_sql_exception: Incorrect integer value: '' for column 'boolean_X' at row 1 in yourFile.php PHP 致命错误:未捕获的 mysqli_sql_exception:不正确的整数值:''for 'boolean_X' 列在 yourFile.php 的第 1 行
