MySQL and/or query for advanced search between several tables - mysql

Question

Now, I am using this query
SELECT h . * ,
(SELECT state
FROM house_name
WHERE name = h.house_name
AND purpose = h.purpose
AND district_id = (
SELECT id
FROM district
WHERE name = h.district )
LIMIT 1
) AS hstate,
(SELECT name
FROM district
WHERE id = (
SELECT district_id
FROM house_name
WHERE name = h.house_name
LIMIT 1 )
LIMIT 1
) AS origin_d,
(SELECT id
FROM house_name
WHERE name = h.house_name
AND purpose = h.purpose
AND district_id = (
SELECT id
FROM district
WHERE name = h.district )
LIMIT 1
) AS hnameid,
m.display_name
FROM house_detail h
LEFT JOIN members m ON m.id = h.member_id
WHERE
h.deleted =0
AND h.approve =0
AND
(SELECT state
FROM house_name
WHERE state = 'N'
AND name = h.house_name
AND purpose = h.purpose
AND district_id = (
SELECT id
FROM district
WHERE
name = h.district )
LIMIT 1
) IS NOT NULL
AND h.price <=1000000
OR h.price >=70000000
OR (
h.purpose = 'house'
AND h.rent >=100000
)
OR (
h.purpose = 'industry'
AND h.rent >=700000
)
OR h.rent <=5000
On the Where clause:
The h.approve can be 0 or 1 or 2
The h.deleted can be 0 or 1
The state can be Y or N
What I want to do is:
The h.deleted , h.approve and the state MUST be 0, 0 and N respectively
The h.rent and h.price may under a specific range.
And the current problem is it will still select some data where the h.deleted , h.approve and state may be 1 or 2 , 1 and Y. I think it's because there're some OR between them.
Is there any way to output my expected result ?

Answer 1

Set bracket around the following statements:
WHERE
name = h.district )
LIMIT 1
) IS NOT NULL
AND (h.price <=1000000
OR h.price >=70000000
OR (
h.purpose = 'house'
AND h.rent >=100000
)
OR (
h.purpose = 'industry'
AND h.rent >=700000
)
OR h.rent <=5000)
opening ( after the last AND and closing ) at the end... that should do
