Question

I am new at this and stuck for days…trying everything I could find from Google and these Forums.

I have one MySQL table that I need to pull data from.

I need to pull all records where AgentID = 1234
Also, pull all records where OfficeID = 4321 (and AgentID != 1234 to prevent dupes)
Then display the results with AgentID records first, if they exist, then the OfficeID records.

I tried a UNION, but could not find a way to sort or show Agent first, Office second.
Tried array_merge and two queries/results, but the merged data was mixed instead of Agent First data, again, with no way to sort by Agent first.

Any ideas would be greatly appreciated!

You can use a CASE statement in the ORDER BY to impose your specified conditions.

SELECT *
    FROM YourTable
    WHERE AgentID = 1234
        OR (OfficeID = 4321 AND AgentID <> 1234)
    ORDER BY CASE WHEN AgentId = 1234 THEN 0 ELSE 1 END,
             AgentID, OfficeID
