I have several tables that I am selecting data from. I am trying to get a list of information out of these tables only where the fields
“interested_parties.emp_id” and “solicitation_entrys.sol_ent_id” are satisfied.

This is my query that I have come up with so far:

SELECT * FROM users 
JOIN interested_parties ON (users.emp_id = interested_parties.emp_id) 
JOIN department_colors ON (department_colors.dept_id = users.emp_dept) 
JOIN solicitation_entrys ON (solicitation_entrys.sol_ent_id = interested_parties.sol_ent_id) 
WHERE IS NOT NULL (interested_parties.emp_id, solicitation_entrys.sol_ent_id)

The goal is to select everything from these tables, where these fields are not null.
I’m getting #1064 errors from MySQL and I can’t seem to solve the issue. Do I have to perform the if at the beginning of the select? If so, how would you do that with joins?
Thank you for your help.

    Use this instead 

    SELECT * FROM users 
JOIN interested_parties ON (users.emp_id = interested_parties.emp_id) 
JOIN department_colors ON (department_colors.dept_id = users.emp_dept) 
JOIN solicitation_entrys ON (solicitation_entrys.sol_ent_id = interested_parties.sol_ent_id) 
WHERE interested_parties.emp_id IS NOT NULL 
AND solicitation_entrys.sol_ent_id IS NOT NULL

    You have to compare each field for not being null.
