Hi All,

I am using sql server 2012. Can anybody please guide how I can combine the following 2 commands into one.

SQL

Select distinct PROJN from PROJ
 JOIN [USER] ON PROJ.PROJWD=[USER].USERT WHERE ([USER].USERID=@USER)
 ;

Select distinct PROJN from PROJ
WHERE PROJ.PROJWD IN (SELECT DEPTN FROM DEPT WHERE DEPTH=@USER or deptd=@USER)

I require the resultant datatable to have distinct combine result of both queries.
For coding I am using vb in asp.net.

Thanks in advance..

How do you want the results combined?
Do you want the rows that satisfies both queries, or the rows that satisfies either query

Solution 1

You can try this also

SQL

Select distinct PROJN from PROJ
 JOIN [USER] ON PROJ.PROJWD=[USER].USERT WHERE ([USER].USERID=@USER)
or PROJ.PROJWD IN (SELECT DEPTN FROM DEPT WHERE DEPTH=@USER or deptd=@USER)

SQL

You can use either union or union all to combine the two queries.


Select distinct PROJN from PROJ
 JOIN [USER] ON PROJ.PROJWD=[USER].USERT WHERE ([USER].USERID=@USER)

union/Union all

Select distinct PROJN from PROJ
WHERE PROJ.PROJWD IN (SELECT DEPTN FROM DEPT WHERE DEPTH=@USER or deptd=@USER)
