T-SQL Getting duplicate rows returned
- by cBlaine
The following code section is returning multiple columns for a few records.
SELECT a.ClientID,ltrim(rtrim(c.FirstName)) + ' ' +
case when c.MiddleName <> '' then
ltrim(rtrim(c.MiddleName)) + '. '
else ''
end +
ltrim(rtrim(c.LastName)) as ClientName, a.MISCode, b.Address, b.City, dbo.ClientGetEnrolledPrograms(CONVERT(int,a.ClientID)) as Abbreviation
FROM ClientDetail a
JOIN Address b on(a.PersonID = b.PersonID)
JOIN Person c on(a.PersonID = c.PersonID)
LEFT JOIN ProgramEnrollments d on(d.ClientID = a.ClientID and d.Status = 'Enrolled' and d.HistoricalPKID is null)
LEFT JOIN Program e on(d.ProgramID = e.ProgramID and e.HistoricalPKID is null)
WHERE a.MichiganWorksData=1
I've isolated the issue to the ProgramEnrollments table.
This table holds one-to-many relationships where each ClientID can be enrolled in many programs. So for each program a client is enrolled in, there is a record in the table.
The final result set is therefore returning a row for each row in the ProgramEnrollments table based on these joins.
I presume my join is the issue but I don't see the problem.
Thoughts/Suggestions?
Thanks,
Chuck
