It is nearly impossible to determine what is what from this. Please post ddl (create table statements) and sample data (insert statements).

I would recommend steering well away from this type of splitter. They perform acceptably for very small datasets, of course it is still a scalar function so the versatility of this is limited. You should take a look at the link in my signature about splitting strings. It is a much better approach than looping.

Looking at your original post again I think that Col2, Col3 and Col4 are just noise to the problem? All that really matters here is Col1 and Col5.

Here is an example of what I mean about posting consumable ddl and sample data.

create table #Something

(

Col1 char(1),

col2 char(5),

Col3 char(5),

Col4 int,

Col5 varchar(100)

)

insert #Something

select 'A', '11:30', '13:30', 15, '11.30,11.45,12.00,12.15,12.30,12.45,13.00,13.15,13.30'

To get this data we just need to split the value in Col5. This is easily done using the DelimitedSplit8K function. You can learn more about that function (and find the code for it) by following the link in my signature about splitting strings.

select Col1, x.Item as Col5Values

from #Something

cross apply dbo.DelimitedSplit8K(Col5, ',') x

This post looks really related to this other

Is it really about different things? or are you deciphering my code?

Just to reinforce what Sean stated, if you have a splitter function with a WHILE loop or the word BEGIN in it, it should be avoided even if you're "just doing something small".

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
