将变量插入临时表

Question

How can I insert declared var into temp table?

DECLARE   @ConcatString VARCHAR(4000)
SELECT   @ConcatString = COALESCE(@ConcatString + ', ', '') + LanguageName FROM EmployeeLanguage  where  EmployeeId=10504
SELECT   @ConcatString AS Language

GO

DECLARE @T1 TABLE (
Item1 BigInt,
Item2 VARCHAR(200)
)
INSERT INTO @T1 select 1,(SELECT   @ConcatString AS Language ) as t

select * from @T1

Answer 1

Remove the GO statement. It separates the query into two batches, and variables are only scoped to the batch they're created in.

You also don't need the sub-select. Just do the following:

Insert Into @T1 
       (Item1, Item2)
Select 1, @ConcatString;

Answer 2

Make the following changes to the query

1. Remove the keyword GO.
2. Item2 VARCHAR(200) column size to VARCHAR(4000)

     if @ConcatStringlength exceed the current  Item2 VARCHAR(200)

• else error : String or binary data would be truncated. The statement has been terminated.
