使用游标，如下
CREATE PROCEDURE proc_getalltable
AS
BEGIN
SET NOCOUNT ON;
DECLARE @tablename VARCHAR(100),@sql VARCHAR(1000)
DECLARE tablename CURSOR FOR SELECT tname FROM tablelist
OPEN tablename
FETCH NEXT FROM tablename INTO @tablename
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @sql = 'SELECT * FROM ' + @tablename
EXEC(@sql)
FETCH NEXT FROM tablename INTO @tablename
END
CLOSE tablename
DEALLOCATE tablename
END
GO
