sql-server,join , ONLY display certain rows from an inner joined table using a certain colum as a parameter from one of the inner joined tables


ONLY display certain rows from an inner joined table using a certain colum as a parameter from one of the inner joined tables

Question:

Tag: sql-server,join

I have two tables, one with various details such as

Username, email id, user code 

and another table with columns which are:

UserCode, supervisor email id, active_flag

I required an output of a table which only displays the active users i.e. the users with active_flag (Y or N) column as 'Y'.

So as of now I have Inner Joined these two tables on UserCode as it exists in both and my table now looks like:

|Username| Email ID      | SuperVisor Email ID|
|Dan     | [email protected] | [email protected]    |
|John    | [email protected] | [email protected]    |

Is there a way that I can check from one of my tables the data from the column ACTIVE_FLAG and only display the active (Y) user details into this Inner Joined table?

I have searched on stack overflow but couldn't find a solution which I could use.


Answer:

If I understood correctly this should be what you're looking for

SELECT A.UserName, A.[Email ID], A.[Supervisor Email ID]
FROM A INNER JOIN B ON A.UserCode = B.UserCode
WHERE B.ACTIVE_FLAG = 'Y'
