I need help with iterating the records of a database table and populating a field with the concatenation of 2 fields in the table.
Posted on 2008-06-16
I currently have a table with the Following fields and records:
Class_ID, Class_Day, Start_Time, End_Time
"GMS-557-01","T","08:30AM"
"GMS-557-01","TH","08:30AM
"GMS-595Y-01","T","1:00PM"
"GMS-610-01","M","08:30AM"

"GMS-649-01","W","08:00AM"
"GMS-649-01","F","08:00AM"
"GMS-710-01","TBA","08:00A
After running a stored procedure preferably or a vb2005 sub procedure in the code of my asp.net 2.0 project I need to have the day(s) that each class meets concatenated and entered in the Class_Days field.
Class_ID, Class_Day, Start_Time, End_Time, Class_Days

create UDF function like in example below (just change table name t1 to yours):
create table t1 (Class_ID varchar(50), Class_Day varchar(50), Start_Time varchar(50), End_Time varchar(50))
insert into t1
select 'GMS-557-01','T','08:30AM','10:50AM'
union all
select 'GMS-557-01','TH','08:30AM','10:50AM'
union all
select 'GMS-595Y-01','T','1:00PM','2:50PM'
union all
select 'GMS-610-01','M','08:30AM','11:50PM'
union all
select 'GMS-623-01','M','01:00PM','05:50PM'
union all
select 'GMS-623-01','W','03:00PM','04:50PM'
union all
select 'GMS-623-01','F','01:00PM','02:30PM'
union all
select 'GMS-649-01','W','08:00AM','09:50AM'
union all
select 'GMS-649-01','F','08:00AM','09:50AM'
union all
select 'GMS-710-01','TBA','08:00AM','09:50AM'
go
--create UDF
create FUNCTION udf_Class_Days (@Class_ID varchar(30))
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE @strOutput VARCHAR(8000)
SELECT @strOutput =
COALESCE(@strOutput + ',','') +Class_Day
FROM dbo. t1
WHERE [Class_ID] = @Class_ID
RETURN @strOutput
end
GO
-----------------
-- Test code:
select *,dbo.udf_Class_Days(Class_ID) from t1
Thank you so much EugeneZ, this is great! You well deserve your rank!
Here is my test and the results I got:
