錯誤不會攔截,而且控制權會從建構傳出TRY...CATCH至下一個較高層級。 在SELECT預存程式內執行 語句會導致錯誤發生在低於 區塊的TRY層級。 錯誤是由TRY...CATCH建構所處理。 SQL -- Verify that the stored procedure does not exist.IF OBJECT_ID(N'usp_ExampleProc', N'P') IS NOT NULLDROPPROCEDUREusp...
也就是说它无法被CATCH到 2. 中等错误(严重性级别为11-19):能够被CATCH到(不管是在T-SQL里面还是在客户程序里面) 3. 严重错误(严重性级别为20-25):SQL Server将强制把连接关掉。很显然这也不可能被CATCH到 【重点提示!!】 由于业务的复杂或者系统性能问题,致使数据库sql语句执行较久。 导致客户端网页已经连...
未捕捉错误,控制从TRY...CATCH构造传递给下一更高级别。 在存储过程内运行SELECT语句将导致错误在低于TRY块的级别上发生。 该错误将由TRY...CATCH构造处理。 SQL -- Verify that the stored procedure does not exist.IF OBJECT_ID ( N'usp_ExampleProc', N'P' ) IS NOT NULLDROPPROCEDUREusp_ExampleProc;...
用SQL Server 2005的TRY...CATCH模块处理Errors 虽然SQL Server 2005依然支持@@ERROR方法,但还有一个更好的处理方法,那就是新特性TRY...CATCH模块.就像程序语言Visual Basic, C#,以及Java一样,SQL Server 2005的TRY...CATCH模块在TRY模块里执行一系列的statement,如果执行这些statement都没有问题那么程序就跳过 CATC...
* CATCH 块 - 如果TRY块出现异常,代码处理流将被路由到CATCH块.在这⾥你可以处理异常,记录⽇志等.Sql Server中的Try Catch和C#,JAVA等语⾔的处理⽅式⼀脉相承.这种⼀致性才是最⼤的创新之处.⼀、SQL SERVER 2000中异常处理 CREATE PROC usp_AccountTransaction @AccountNum INT,@Amount DECIMAL ...

stored procedure is executed in the CATCH block. By doing this, you do not have to repeat the error handling code in every CATCH block. In the follow code example, the SELECT statement in the TRY block will generate a divide-by-zero error. The error will be handled by the CATCH block...
If the stored procedure contains a TRY...CATCH construct, the error transfers control to the CATCH block in the stored procedure. When the CATCH block code finishes, control is passed back to the statement immediately after the EXECUTE statement that called the stored procedure.GOTO...
• You have a stored procedure that contains aTRY…CATCHconstruct in Microsoft SQL Server. • The stored procedure includesWITH RESULT SETSclause and is executed by the sp_prepare or sp_execute method. • Before you ex...
