I'm trying to figure out how to include row values as columns in my select query. I have a table that stores comments for different sections in a web application. In the table below, I would like display each comment as a new column. I only want one row for each record_ID.
Existing table layout
table name - tblcomments
Record_ID Comment_Section_ID Comment
1 5 Test 5 comment
1 7 Test 7 comment
2 5 New comment
2 7 Old comment
3 5 Stop
3 7 Go
Desired table layout
table name - #tempComment
Record_ID Comment_Section_5 Comment_Section_7
1 Test 5 comment Test 7 comment
2 New comment old comment
3 Stop Go
Once I figure out how to get the data in the layout above, I will need to join the table with my record table.
table name - tblRecord
Record_ID Record_Type_ID Record_Status
1 23 Closed
2 56 Open
3 67 Open
4 09 Closed
5 43 In progress
I would like to be able to join the tables in the query below for the final output.
Select r.Record_ID, r.Record_Type_ID, r.Record_Status,
c.Comment_Section_5, c.Comment_Section_7
from tblRecord r
left outer join #tempComment c
on r.record_ID = c.record_ID
Can anyone explain how I can get the data in the desired #tempComment table layout mentioned above?

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.
