I have 3 tables A, B and C
I am doing this :- /* There is no relation between Table A and Table B . Table A is just used to provide values to C.Profile */ 1st step ) D <---- Select * from C where Profile=1 // want to give a specific ProID(I have successfully retrieved it from A table)
2nd Step ) Output <--- Select B.sname,D.Status from B Left Join D On B.ID=D.ID
so that the output looks like the required output table shown above:-
Can I do this by using a single query? how?
Do you mean a subquery:
Select B.DirName,D.Status
from B Left Join (
Select *
from C
where ProId=1) As D
On B.DirID=D.DirID
It is best to use a list of fields rather than *
