执行sql任务错误

Question

执行sql任务定义如下。参数映射是 system：用户名输入varchar 0 -1 系统：packagename输入varchar 1 -1

DECLARE @DataLoaderUsername VARCHAR(100)
DECLARE @PackageName VARCHAR(100)
DECLARE @Code VARCHAR(5)
DECLARE @RunNumber INT

SET @DataLoaderUsername = ?
SET @PackageName = ?
SET @Code = 'bbb'


INSERT INTO tBL_Log
(LoadDateTime,DataLoaderUsername,PackageName,Code)
SELECT GetDate(),@DataLoaderUsername,@PackageName ,@Code

SELECT @RunNumber = Max(RunNumber) 
FROM tBL_Log

SELECT @RunNumber As LoadID

显示错误

Execute SQL Task] Error: Executing the query "DECLARE @DataLoaderUsername VARCHAR(100)

在ssms中执行相同的查询，它工作正常（使用硬编码的用户名）

Answer 1

在每个SQL命令的末尾放置分号。当SSIS将命令发送到SQL Server时，它将其作为单行发送，因此需要使用分号来显示每个新命令开始的SQL Server。

Answer 2

Your code inside the Execute SQL Task should only contain the following.

INSERT INTO tBL_Log
(LoadDateTime,DataLoaderUsername,PackageName,Code)
SELECT GetDate(),? ,?, 'bbb'

SELECT LoadID = Max(RunNumber) 
FROM tBL_Log

In the General page, make sure you have ResultSet set to single row, and the DB connection also set to a valid connection manager.

I think you've already setup your Parameters page, just make sure they look like the following. Remember the index for the parameters starts at 0 and is specified in the Parameter Name box (Not intuitive, I know. It tripped me up in the beginning when I was learning SSIS).

Finally, in order to get the LoadId value that you are selecting in the last statement, create a variable to hold that value in the ResultSet pane. The ResultSet should be called 0.

So it looks like this.
