Question

I am trying to create a view for a UNION of 2 select statements that I have created.

The UNION is working fine when executed individually

But the problem is only the 1st part of the UNION is getting executed when I am executing it as a view.

The query I am using is as below

   SELECT DISTINCT   products.pid        AS id,   products.pname      AS name,   products.p_desc     AS description,   products.p_uid      AS userid,   products.p_loc      AS location,   products.isaproduct AS whatisit FROM products UNION SELECT DISTINCT   services.s_id       AS id,   services.s_name     AS name,   services.s_desc     AS description,   services.s_uid      AS userid,   services.s_location AS location,   services.isaservice AS whatisit FROM services 

The above works fine when i execute it separately. But when I use it as a view, it does not give me the results of the services part.

Could someone please help me with this?

Try this

   SELECT DISTINCT   products.pid        AS id,   products.pname      AS name,   products.p_desc     AS description,   products.p_uid      AS userid,   products.p_loc      AS location,   products.isaproduct AS whatisit FROM products UNION ALL SELECT DISTINCT   services.s_id       AS id,   services.s_name     AS name,   services.s_desc     AS description,   services.s_uid      AS userid,   services.s_location AS location,   services.isaservice AS whatisit FROM services 

I’m not sure, I tried that with a table on my server and it worked.. I guess it will work for you. Hint the only difference here is that I used ‘union all’ instead of just ‘union’
