I have this SQL:
SELECT
`refnumbers`.`order_id`,
`refnumbers`.`deal_id`,
`refnumbers`.`claim_track_id`,
`deals`.`partner_count`
FROM `refnumbers`
JOIN `deals`
ON (`refnumbers`.`deal_id` = `deals`.`ID`)
JOIN `users`
ON (`users`.`id` = `deals`.`partner_id`)
WHERE `refnumbers`.`is_claimed` = '1'
AND `deals`.`partner_id` = '62039'
AND `refnumbers`.`claimed_at` BETWEEN '2013-01-17 00:00:00'
AND '2013-01-17 23:59:59'
ORDER BY `refnumbers`.`claimed_at` DESC
I would like to select where deals.partner_id = 62039 IF deals.partner_count is 1.
If partner_count isnt 1 then it should select where refnumbers.claim_track_id = 62039
How can this be done?
try
where
case when deals.partner_count = 1
then deals.partner_id = 62039
else refnumbers.claim_track_id = 62039
end
You need to have a condition enclose in a parenthesis which uses OR
SELECT `refnumbers`.`order_id`,
`refnumbers`.`deal_id`,
`refnumbers`.`claim_track_id`,
`deals`.`partner_count`
FROM `refnumbers`
INNER JOIN `deals`
ON (`refnumbers`.`deal_id` = `deals`.`ID`)
INNER JOIN `users`
ON (`users`.`id` = `deals`.`partner_id`)
WHERE `refnumbers`.`is_claimed` = '1' AND
`refnumbers`.`claimed_at` BETWEEN '2013-01-17 00:00:00' AND '2013-01-17 23:59:59'
AND
(
(deals.partner_id = 62039 AND deals.partner_count = 1)
OR
(refnumbers.claim_track_id = 62039 AND deals.partner_count <> 1)
)
ORDER BY `refnumbers`.`claimed_at` DESC
Try this:
SELECT r.order_id, r.deal_id,r.claim_track_id, d.partner_count
FROM refnumbers r
INNER JOIN deals d ON r.deal_id = d.ID
INNER JOIN users u ON d.partner_id = u.id
WHERE IF(d.partner_count = 1, d.partner_id = '62039', r.claim_track_id = 62039) AND
r.is_claimed = '1' AND r.claimed_at BETWEEN '2013-01-17 00:00:00' AND '2013-01-17 23:59:59'

This query took me more than 30sec or more! The query inside the NOT IN is little bit huge around 7-9k of ids. Is there a more efficient way of doing this? I think the inner join part is make it slow where the checking the two column of n_combine_tables which is (comb_id1 or comb_id2).
Is there a more efficient way of doing this?
I'd remove duplicated conditions in sub-queries and do something like this (two NOT in could be replaced with UNION):
SELECT
SUM(m.m_out) AS totalOut
FROM
m_detal AS m
WHERE
m.opers = '25'
AND m.m_type IN ('Out', 'Merged')
AND m.m_date <= '2018-11-28 07:30:00'
AND m.mark_delete IS NULL
AND m.m_onhold = 'onhold'
AND m.m_ids NOT IN (
SELECT
t1.comb_id1
FROM
n_combine_tbl AS t1
WHERE
t1.time <= '2018-11-28 07:30:00'
)
AND m.m_ids NOT IN (
SELECT
t2.comb_id2
FROM
n_combine_tbl AS t2
WHERE
t2.time <= '2018-11-28 07:30:00'
)
;
OR with NOT EXISTS:
SELECT
SUM(m.m_out) AS totalOut
FROM
m_detal AS m
WHERE
m.opers = '25'
AND m.m_type IN ('Out', 'Merged')
AND m.m_date <= '2018-11-28 07:30:00'
AND m.mark_delete IS NULL
AND m.m_onhold = 'onhold'
AND NOT EXISTS (
SELECT
*
FROM
n_combine_tbl AS t
WHERE
t.time <= '2018-11-28 07:30:00'
AND (
t.comb_id1 = m.m_ids
OR t.comb_id2 = m.m_ids
)
)
;
You should check the 'onhold' logic.
You should try to add indexes on n_combine_tbl: (time, comb_id1), (time, comb_id2), (comb_id1, time), (comb_id2, time) and check what is good for your data.
Multi-column indexes on m_detal table should also be considered.

Hi friends I would like to retrieve the value of department quantity When process.UOM = 1 else if process.UOM = '2' THEN SET (com_jobcard.total_stones) AS Total_qty , please help me with the code , thanks in advance
You can use case-when something as
SELECT
process.process_name,
com_jobcard.job_card_num,
case
when process.UOM = '1' then com_jobcard.dept_qty
when process.UOM = '2' then com_jobcard.total_stones
end as Total_qty
FROM timer_completed
INNER JOIN PROCESS ON process.id = timer_completed.process_id
INNER JOIN com_jobcard ON timer_completed.job_card_id = com_jobcard.id
AND timer_completed.report_date = '2015-09-15'
NOTE : Right now there is no else so its better to add an else if both condition fails
case
when process.UOM = '1' then com_jobcard.dept_qty
when process.UOM = '2' then com_jobcard.total_stones
else 'something you want'
end as Total_qty
IF(condition, true_value, false_value) can be used this way
SELECT process.process_name, com_jobcard.job_card_num,
IF(process.UOM = '1', com_jobcard.dept_qty, IF(process.UOM = '2', com_jobcard.total_stones, 0)) AS Total_qty

I have the result returning the way I want - I just want to ignore rows where MPG_VALUE > 30 (nvdtechnical.TECH_Value_Float)
But my query returns all - and unwanted rows have NULL in MPG_VALUE column.
How can I return only rows where MPG_VALUE > 30 ?

That is because you are doing a scalar query for the MPG Value. You are not really filtering which rows to show or hide, rather, you are showing all rows that has a value matched from your main query.
Imagine a left join, that is like what you are doing
SELECT nvdtechnical.TECH_Value_Float FROM nvdtechnical
WHERE TECH_TechCode = '11'
AND nvdtechnical.TECH_Id = capder.cder_ID
**AND nvdtechnical.TECH_Value_Float > 30**
LIMIT 1
to properly filter the data, you must filter in once more outside it in your where condition:
the easiest way would be like this one.
SELECT *

SELECT *, (SELECT PR_Basic + PR_VAT + PR_Delivery FROM nvdprices
WHERE PR_Id = capder.cder_ID ORDER BY PR_EffectiveTo ASC LIMIT 1) as P11D,
