Sql语法高级应用之七：如何在存储过程中使用事务

普通事物：

USE Wot_Inventory;

GO
BEGIN TRANSACTION tr;
DECLARE @error INT;
SET @error = 0;
SELECT * FROM Wot_Inventory.dbo.Logistics;
SET @error = @error + @@ERROR;
SELECT 1 / 0;
SET @error = @error + @@ERROR;
SELECT * FROM Wot_Inventory.dbo.Invoice;
SET @error = @error + @@ERROR;
PRINT 'i have executed!';
SET @error = @error + @@ERROR;

PRINT '@@error:' + CAST(@error AS VARCHAR(50));
IF (@error <> 0)
BEGIN
    PRINT 'executed failed';
    ROLLBACK TRANSACTION tr;
END;
ELSE
BEGIN
    PRINT 'executed success';
    COMMIT TRANSACTION tr;
END;

结合TRY...CATCH的SQL事物

USE Wot_Inventory;

GO
BEGIN TRY
    BEGIN TRANSACTION tr;

    UPDATE dbo.Logistics SET EngFlag = 1 WHERE LogisticCode = '620752867926';
    SELECT 1 / 0;
    PRINT 'i have executed!';
    SELECT * FROM dbo.Logistics;

    PRINT 'executed success';
    COMMIT TRANSACTION tr;

END TRY
BEGIN CATCH
    PRINT 'executed failed';
    ROLLBACK TRANSACTION tr;
END CATCH;
