I would like to run a query very similar to this on one of my production databases:
-- Setup the table (Already there in my real scenario) create table dbo.MyTable(MyValue int, MyGroup varchar(5)) insert into dbo.MyTable values (56,'I'), (12,'I'), (56, 'II'), (12, 'II'), (56, 'III'), (56, 'IV'), (56, 'V'), (12, 'V') -- Create a function to cross apply with (I can't make this in my production env) create function dbo.GetOrderGroup(@groupName varchar(15)) returns @ReturnTable table(GroupValue varchar(8000), GroupName varchar(15)) as begin DECLARE @groupValue VARCHAR(8000) SELECT @groupValue = COALESCE(@groupValue + ', ' + cast(MyValue as VARCHAR(10)), cast(MyValue as VARCHAR(10))) FROM MyTable where MyGroup = @groupName insert into @ReturnTable(GroupValue, GroupName) SELECT @groupValue, @groupName return; end; go -- cross apply and get the distinct values SELECT grp.GroupValue, count(distinct (grp.GroupValue + grp.GroupName)) as 'Count' from MyTable tbl (NOLOCK) cross apply dbo.GetOrderGroup(tbl.MyGroup) grp GROUP BY grp.GroupValue
But I don't have rights to create a User Defined Function on that database (I am a developer).
Is there a way to accomplish this query with out the use of a user defined function (or any other "Create" statement)?
Note: I tried doing a cross apply with the contents of my Function, but it failed (I don't think multi-statement expressions are allowed in the Cross Apply).
