db query problem

I'm using MS SQL Server 2000 and I have a table called tasks with the following schema: id= int identity 1 1 not null standardId= varchar(15) not null userId= varchar(15) not null status= varchar(15) not null beginDt= datetime endDate=datetime active=char(1) // flag 1=display 0=do not display I need to return records based on userId and standardId. Assume I have the following five records: userId: jimmy standardId: EC.01.10 userId: jimmy standardId: RI.03.20 userId: karen standardId: PC.02.40 userId: sally standardId: EC.01.10 userId: ted standardId: RI.03.20 userId: joe standardId: EC.01.10 These are the results I need to return: All of jimmy's records: where userId='jimmy' I also need to return all records that match all of jimmy's standardId(s), in other words, I need to return in all other records where standardId='EC.01.10 or standardId='RI.03.20 (without duplicating jimmy's results). Which in this scenario would be userId sally, joe, ted I also need to group the records by standardId. Can this be done in a subquery or is two queries required? Having worked mostly with MySQL I dont' have a lot of experience with subqueries. Any suggestions on the best way to approach this probelm?
