| Trying to think of any reason to do this (similarly for the other 2 times this sort of question has come up on other sites today)You can only have a max of 12 months so why not create them all and leave them as null.something like this to add columnsselect month into #a from monthtbl left outer join syscolumns c on c.name = monthtbl.month and c.id = object_id('coltbl') where c.name is nulldeclare @col varchar(128), @sql varchar(1000)select @col = ''while @col < (select max(month) from #a)beginselect @col = min(month) from #a where month > @colselect @sql = 'alter table coltbl add ' + @col + ' varchar(10) null'exec (@sql)end==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |
