【问题描述】:
首先我的引擎是 innoDB,我已经在 mySQL 上尝试了以下内容:
BEGIN;
INSERT INTO `tbl_users`(...) VALUES (...)
ROLLBACK();
它工作正常,这意味着问题不在我的 mysql 配置中。
但是当我在我的 Laravel 模型上尝试这个时:
public static function addNew($request, $department_id) {
$result = array();
$now = Carbon::now();
DB::beginTransaction();
//Checking for existing Order to set appropriate starting ID
$result = DB::select("
SELECT COUNT(`id`) AS 'count'
FROM `tbl_consignmentorders`
")[0];
if($result->count == 0){
DB::update("ALTER TABLE `tbl_consignmentorders` AUTO_INCREMENT = 70000000001;");
}
try {
//INSERT
DB::insert("
INSERT INTO `tbl_consignmentorders`
(`from`, `to`, `status`, `created_at`, `updated_at`)
VALUES
(?, ?, ?, ?, ?)",
[
$department_id,
strtoupper($request->input('supplier')),
'PENDING',
$now,
$now
]
);
//GET THE LAST ID INSERTED, NEEDED FOR NEXT INSERT
$last_id = DB::select("
SELECT
LAST_INSERT_ID() AS 'id'
FROM `tbl_consignmentorders`;"
)[0]->id;
//CONSTRUCTING QUERY STRING FOR VALUES
$values = '';
$count = 0;
foreach($request->input('item_id') as $item) {
$values .= ',(' . $request->input('quantity')[$count] . ', ' . $last_id . ', ' . $item . ', ' . $request->input('item_price_id')[$count] . ' )';
$count++;
}
$values[0] = ' ';
//INSERT TO DETAILS
DB::insert("
INSERT INTO `tbl_consignmentorderdetails`
(`quantity`, `order_id`, `item_id`, `item_price_id`)
VALUES
$values;"
);
//INSERT TO TRANSACTION AUDIT
DB::insert("
INSERT INTO `tbl_transactions`
(`type`, `reference_id`, `department_id`, `created_at`, `updated_at`)
VALUES
(?, ?, ?, ?, ?)",
[
'CONSIGNMENT ORDER',
$last_id,
$department_id,
$now,
$now
]
);
//COMMIT NOTHING FAILS
DB::commit();
$result = true;
} catch (\Exception $e) {
//ROLLBACK SOMETHING IS WRONG
DB::rollback();
$result = $e->getMessage();
}
return $result;
}
现在上面的代码在成功的时候可以正常工作,现在要产生错误,我会故意改变这部分代码:
//GET THE LAST ID INSERTED, NEEDED FOR NEXT INSERT
$last_id = DB::select("
SELECT
LAST_INSERT_ID() AS 'id'
FROM `tbl_consignmentorders`;"
)[0]; //<--- I removed the ->id to return the whole object causing object to string error on the next query
现在正如预期的那样,它会转到 catch 块来传递错误消息,但是在错误之前执行的查询仍然存在于数据库中它不应该存在的地方。
