如何多次在临时表中插入值

Question

I have this code. Can I insert values into a temp table multiple times? I have list of ids (ie 1000 ids). I want to insert this by loop.

DECLARE @tempTable TABLE(col1 INT)

FOR (@ids IS NOT NULL) {
    INSERT INTO @tempTable VALUES(@ids)
}

SELECT * FROM @tempTable

Answer 1

Even though it is possible using WHILE loop I will suggest you to go with SET Based approach

Why cant you just do this

INSERT INTO @tempTable (ID)
select Id from yourlist

Answer 2

SQL Server is not support FOR loop. You need to use WHILE loop instead.

Answer 3

You can use a while statement as said Jitendra Tiwari:

DECLARE @tempTable TABLE(col1 INT)

DECLARE @num int 
SET  @num = 1
WHILE @num <= 1000
BEGIN
    INSERT INTO @tempTable VALUES (@num) --(@ids)
    SET @num = @num + 1
END

SELECT * FROM @tempTable
