How can i create an auto increment value inserted into table when i'm using the Insert INTO ... SELECT ?

example:
INSERT INTO ISSUE (MEDIAID, PUBDATE, ISSUE)
SELECT MEDIAID, PUBDATE,  ISNULL(MAX(@STARTING_VALUE), 0) + 1

What i want to do is pass a starting value (a number) and then all the records inserted must count from this number .

For example if i pass @STARTING_VALUE=15 and the select returns 3 records, i want the following:

15, 21/7/2006, 15
15, 21/7/2006, 16
15, 21/7/2006, 17

IF YOU HAVE EXISTING TABLE NAME ISSUE THEN USE THIS


DECLARE @MEDIAID VARCHAR(10),
      @PUBDATE DATETIME,
      @ISSUE INT


DECLARE C CURSOR FOR SELECT MEDIAID, PUBDATE FROM YOURTABLE

SET @ISSUE =  ISNULL(MAX(@STARTING_VALUE), 0) + 1
OPEN C
FETCH NEXT FROM C INTO @MEDIAID, @PUBDATE
WHILE @@FETCH_STATUS = 0
BEGIN

INSERT INTO ISSUE (MEDIAID, PUBDATE, ISSUE)
SELECT MEDIAID, PUBDATE, @ISSUE

SET @ISSUE = @ISSUE +1
FETCH NEXT FROM C INTO @MEDIAID, @PUBDATE
END
CLOSE C
 DEALLOCATE C
GO

use a temptable to order the rows...

SELECT IDENTITY(int, 0,1) AS ID_Num, MEDIAID, PUBDATE
INTO #temp
FROM selectTable
order by ....

then

INSERT INTO ISSUE (MEDIAID, PUBDATE, ISSUE)
SELECT MEDIAID, PUBDATE,  @STARTING_VALUE + ID_Num
 from #temp

AND IF YOU HAVE STRING VALUE 15 THEN USE THE BELOW SCRIPT


DECLARE @MEDIAID VARCHAR(10),
      @PUBDATE DATETIME,
      @ISSUE INT


DECLARE C CURSOR FOR SELECT MEDIAID, PUBDATE FROM YOURTABLE

SET @ISSUE =  15
OPEN C
FETCH NEXT FROM C INTO @MEDIAID, @PUBDATE
WHILE @@FETCH_STATUS = 0
BEGIN

SET @ISSUE = @ISSUE +1
INSERT INTO ISSUE (MEDIAID, PUBDATE, ISSUE)
SELECT MEDIAID, PUBDATE, @ISSUE

FETCH NEXT FROM C INTO @MEDIAID, @PUBDATE

If you use SQL Server 2005, try this:

INSERT INTO ISSUE (MEDIAID, PUBDATE, ISSUE)
SELECT MEDIAID, PUBDATE,  @STARTING_VALUE + ROW_NUMBER() OVER(ORDER BY 1)
FROM your_table

If SQL Server 2000, you might need to use a table variable like this (so you don't need to worry about having problems with duplicate naming issues as well as avoiding cursor):

DECLARE @TempTable (MEDIAID INT, PUBDATE DATETIME, SeqNo INT IDENTITY(1, 1))
INSERT INTO @TempTable (MEDIAID, PUBDATE)
SELECT MEDIAID, PUBDATE
FROM your_table

INSERT INTO ISSUE (MEDIAID, PUBDATE, ISSUE)
SELECT MEDIAID, PUBDATE,  @STARTING_VALUE + SeqNo - 1
FROM @TempTable
0
