Question

我在这里得到了一个大小合适的清理查询，只有15行左右的DELETE语句。我注意到由于FK引用约束，最后几行有时会失败，但是一旦我重新运行查询，剩余的数据就会被删除。我的研究让我相信这是一个时间问题。但是，我无法在每个语句后添加GO，因为我的变量会失去范围......

DECLARE @userOrders TABLE(OrderId INT)
DECLARE @userInventoryCatalog TABLE(InventoryId INT)
DECLARE @userSpotCheckRequests TABLE(SpotCheckRequestId INT)

INSERT INTO @userOrders
SELECT OrderId FROM [Order] WHERE UserId = @userId

INSERT INTO @userInventoryCatalog
SELECT InventoryId FROM [Inventory] WHERE UserId = @userId

INSERT INTO @userInventoryCatalog
SELECT SpotCheckRequestId FROM SpotCheckRequest WHERE InventoryId IN (SELECT 
* FROM @userInventoryCatalog)

DELETE FROM ClientCustomerNotes WHERE ClientCustomerId IN (SELECT 
ClientCustomerId FROM ClientCustomers WHERE UserId = @userId)
DELETE FROM InventoryShelveMapping WHERE InventoryId IN (SELECT * FROM 
@userInventoryCatalog)
DELETE FROM UserBinAllocationLog WHERE UserId = @userId
DELETE FROM OrderMantoxTeaInventory WHERE MantoxTeaInventoryId IN (SELECT * 
FROM @userInventoryCatalog)
DELETE FROM InventoryLog WHERE InventoryId IN (SELECT * FROM 
@userInventoryCatalog)
DELETE FROM Analytics WHERE UserId = @userId
DELETE FROM SpotCheckRequestItems WHERE SpotCheckRequestId IN (SELECT * FROM 
@userSpotCheckRequests)
DELETE FROM SpotCheckRequest WHERE InventoryId IN (SELECT * FROM 
@userInventoryCatalog)
DELETE FROM UserNonReturnableItems WHERE InventoryId IN (SELECT * FROM 
@userInventoryCatalog)
DELETE FROM InventoryBundleDefinition WHERE InventoryId IN (SELECT * FROM 
@userInventoryCatalog)
DELETE FROM Inventory WHERE UserId = @userId
DELETE FROM [Log] WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderTracking WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderProperties WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderDimensions WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderAttachments WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderPicker WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderZenDesk WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderReprocessingQueue WHERE OrderId IN (SELECT * FROM 
@userOrders)
DELETE FROM OrderPicker WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM OrderInformation WHERE OrderId IN (SELECT * FROM @userOrders)
DELETE FROM [Notification] WHERE UserId = @userId
DELETE FROM [TransactionPaymentLog] WHERE UserId = @userId
DELETE FROM [TransactionLog] WHERE UserId = @userId
DELETE FROM [Order] WHERE UserId = @userId
DELETE FROM UserContacts WHERE UserId = @userId
DELETE FROM ClientCustomers WHERE UserId = @userId

所以我的问题是：
如何确保多个语句同步运行？

Answer 1

更改isolation level并设置事务并执行delete语句。当您处理删除时，它将确保不更新值，以便delete同步发生。

set transaction isolation level repeatable read BEGIN transaction DELETE Statements.... COMMIT transaction
