有什么办法能捕获到某个实例中所有各连接的错误？

[sheerfish999]

@@ERROR只能返回到本个连接的上个错误，假如我想做个调试器，有什么办法能捕获到其它连接的错误？

在 Transact-SQL 语句完成后，马上把 @@ERROR 存储到一个整型变量中。此变量的值可供以后使用。

可以用临时表记录所有出错信息

USE Northwind
GO

DROP PROCEDURE SampleProcedure
GO
-- Create a procedure that takes one input parameter
-- and returns one output parameter and a return code.
CREATE PROCEDURE SampleProcedure @EmployeeIDParm INT,
@MaxQuantity INT OUTPUT
AS
-- Declare and initialize a variable to hold @@ERROR.
DECLARE @ErrorSave INT
SET @ErrorSave = 0

-- Do a SELECT using the input parameter.
SELECT FirstName, LastName, Title
FROM Employees
WHERE EmployeeID = @EmployeeIDParm

-- Save any non-zero @@ERROR value.
IF (@@ERROR <> 0)
SET @ErrorSave = @@ERROR
INSERT INTO #T SELECT @ERRORSAVE

-- Set a value in the output parameter.
SELECT @MaxQuantity = MAX(Quantity)
FROM [Order Details]

-- Save any non-zero @@ERROR value.
IF (@@ERROR <> 0)
SET @ErrorSave = @@ERROR
INSERT INTO #T SELECT @ERRORSAVE

-- Returns 0 if neither SELECT statement had
-- an error, otherwise returns the last error.
RETURN @ErrorSave
