SQL循环语句示例(3)

OPEN tnames_cursor
DECLARE @tablename sysname
--SET @tablename = 'authors'
FETCH NEXT FROM tnames_cursor INTO @tablename
WHILE (@@FETCH_STATUS <> -1)
BEGIN
IF (@@FETCH_STATUS <> -2)
BEGIN   
SELECT @tablename = RTRIM(@tablename)
EXEC ('SELECT ''' + @tablename + ''' = count(*) FROM '
+ @tablename )
PRINT ' '
END
FETCH NEXT FROM tnames_cursor INTO @tablename
END
CLOSE tnames_cursor
DEALLOCATE tnames_cursor
===================================================
可以用变量的形式来增加，不过你的userid 三位显然不够，因为你要加10000数据，所以要和authnum形式一样，5位才够
下面是一个简单的例子，你可以根据实际需求来改一下。
DECLARE @i int
DECLARE @strUserId varchar(10)
DECLARE @strAuthnum varchar(10)
Set @i = 0
WHILE @i < 10000
BEGIN
Set @i =@i +1
SET @strUserId = RIGHT('00000' + CAST(@i AS varchar(10)),5)
SET @strAuthnum = @strUserId
insert into user_info values(@strUserId,@strAuthnum)
END
