Question

I have a quick question…

I want to combine two sql queries into one but the problem is that both these queries have GROUP BY in it.

Query 1:

SELECT   COUNT(users_survey_answers.ultimate_survey_code)
FROM     company,
         users_codes,
         users_survey_answers
WHERE    company.company_id = users_codes.company_id
  AND    users_codes.email = "[e-mail]"
  AND    users_codes.company_id = users_survey_answers.company_id
  AND    users_survey_answers.completed = 0
GROUP BY users_codes.company_id

Query 2:

SELECT   COUNT(users_rewards.reward_id)
FROM     company, 
         users_codes, 
         users_rewards
WHERE    company.company_id = users_codes.company_id
  AND    users_codes.email = "[e-mail]"
  AND    users_rewards.company_id = users_codes.company_id
  AND    redeemed = 0
GROUP BY users_codes.company_id

I appreciate the help. I have tried so many solutions, still no help.

Thanks.

Try this:

SELECT    company.company_id,
          users_pts.pts as CompanyPts,
          t1.ultimate_survey_code_count,
          t2.reward_id_count
FROM      company,
          users_codes
INNER JOIN (
          SELECT 
              company_id, 
              COUNT(ultimate_survey_code) AS ultimate_survey_code_count
          FROM users_survey_answers
          WHERE completed = 0
          GROUP BY company_id
          ) AS t1
       ON users_codes.company_id = t1.company_id
INNER JOIN (
          SELECT 
              company_id, 
              SUM(IF(redeemed = 0, 1, 0)) AS reward_redeem_zero_count,
              SUM(IF(redeemed = 0, 0, 1)) AS reward_redeem_not_zero_count
          FROM users_rewards
          GROUP BY company_id
          ) AS t2
       ON users_codes.company_id = t2.company_id
INNER JOIN users_pts
       ON users_codes.company_id = users_pts.company_id
WHERE     company.company_id = users_codes.company_id
  AND     users_codes.email = "[e-mail]"

This is untested, but hope meets your need.
