Hello any MS SQL experts out there! please help if you can. i'm trying to run a subquery within a query to keep myself from having to loop over the original query on display and then run additional queries to get the further info. here's the setup. i have two tables:
persons table
column: name (varchar)
column: vehicleids (varchar)
vehicles table
column: id (int pk)
column: vehiclename (varchar)
- The persons table is a list of peoples' names and what kind of vehicle/s they own.
- The persons.vehicleids field is a comma-delimited list of one or more integers which correspond to the vehicles.id field.
- The vehicles table contains a list of vehicles like car, bicycle, motorcycle, etc, distinguished by the vehicles.id field.
The result i want returned by the query is:
NAME - VEHICLES
Joe Somebody - car,bicycle
Sheila Johnson - van,pogostick,motorcycle
John Nobody - skateboard,car
The query i'm trying to run to get this result is:
Code:
SELECT pe.name,
(
SELECT ve.vehiclename
FROM vehicles ve
WHERE CAST(ve.id AS VARCHAR) IN (pe.vehicleids)
) AS vehicles
FROM persons pe
ORDER BY pe.name
It returns the persons names in the first column, but only returns vehicle names in the second column when there's a single id in the persons.vehicleids field. if there's more than one integer in the field, it returns an empty string.
Can anyone tell me what I'm doing wrong? I do have the option of table restructuring if its necessary, but I'm not looking for a stored procedure solution or a temp table solution. Any takers? I would be in the kharmic debt of anyone providing a workable avenue.
Thank you,
Tyler
