MySQL Complex SELECT Query - JOINS - mysql

Question

Please find the SQLfiddle URL:
http://sqlfiddle.com/#!2/c8002/1/0
Actual Output should be:
region_id status1 branches balance fses
status0 discount branch_names telecallers
2 NULL 4 400.00 30 KOTTAKKAL 341.00 3 3
2 NULL 4 800.00 31 KALPETTA 394.00 3 3
I'm getting the repeated output as follows:
region_id status1 branches balance fses
status0 discount branch_names telecallers
2 NULL 4 400.00 30 KOTTAKKAL 341.00 3 3
2 NULL 4 400.00 30 KOTTAKKAL 394.00 3 3
2 NULL 4 800.00 31 KALPETTA 341.00 3 3
2 NULL 4 800.00 31 KALPETTA 394.00 3 3
how do I correct the same?
Thanks & Regards,

Answer 1

I guess you're having a problem in your query structure itself, as it's not simply a request for distinct.
Your joining tables, and retrieving distinct values for each row you have, that you actually wanted to be only one for each of KOTTAKKAL and KALPETTA.
Notice in your example that, although the addition of the clause distinct is performed, no difference will come over, as the rows you have are distinct. In column balance you have both 341.00 and 394.00 for each entry of KOTTAKKAL and KALPETTA.
If using group, yes, you will lose information on balance, as the result return after a group by is only the first of the different elements grouped (in case of a column with multiple values).
You either have to determine what result you want, or cope with having sum other calculation over the column balance.
I guess the result, and the proper join you were willing to do is this:
SELECT DISTINCT E.`region_id`,a0.status0,a1.status1,k.discount,k.branches
,k.branch_names, k.balance,TCLRS.telecallers,FSE.fses
FROM tbl_insurance_excel E
LEFT OUTER JOIN (SELECT E2.region_id, count(`id`) AS status1
FROM tbl_insurance_excel E2 LEFT JOIN tbl_recipt_general_details ON id=insurance_excel_id
JOIN tbl_branches ON policy_closed_branch= branch_id
WHERE E2.`row_status` =1 AND E2.canceled_status='no' AND E2.region_id=2 GROUP BY region_id) a1 ON a1.region_id=E.region_id
LEFT OUTER JOIN (SELECT E2.region_id, count(`id`) AS status0
FROM tbl_insurance_excel E2 LEFT JOIN tbl_recipt_general_details ON id=insurance_excel_id
JOIN tbl_branches ON policy_closed_branch= branch_id
WHERE E2.`row_status` =0 AND E2.canceled_status='no' AND E2.region_id=2 GROUP BY region_id) a0 ON a0.region_id=E.region_id
LEFT JOIN (
SELECT IEX.region_id, B.branch_name AS branch_names, B.branch_id AS branches, sum( DDT.discounts_amount ) AS discount, sum( RGD.`recipt_bal_amount` ) AS balance
FROM tbl_insurance_excel IEX
LEFT JOIN tbl_recipt_general_details RGD ON IEX.id = RGD.insurance_excel_id
LEFT JOIN tbl_discounts_details DDT ON RGD.rec_gene_id = DDT.recipt_general_id
LEFT JOIN tbl_branches B ON B.branch_id = RGD.policy_closed_branch
WHERE IEX.region_id =2
GROUP BY B.branch_id)k ON k.region_id=E.region_id
LEFT JOIN (
SELECT ex.region_id, B.branch_id AS branches, count( F.`fse_id` ) AS telecallers
FROM tbl_branches B
LEFT JOIN tbl_team_leader L ON B.branch_id = L.leader_branch_id
LEFT JOIN tbl_fse F ON L.leader_id = F.leader_id
JOIN (
SELECT region_id
FROM tbl_insurance_excel
WHERE `region_id` =2
GROUP BY region_id
) AS ex ON B.region_id = ex.region_id
WHERE F.fse_category = 'Telecaller'
GROUP BY B.branch_id
) TCLRS ON TCLRS .region_id=E.region_id
LEFT JOIN (
SELECT ex.region_id, B.branch_id AS branches, count( F.`fse_id` ) AS fses
FROM tbl_branches B
LEFT JOIN tbl_team_leader L ON B.branch_id = L.leader_branch_id
LEFT JOIN tbl_fse F ON L.leader_id = F.leader_id
JOIN (
SELECT region_id
FROM tbl_insurance_excel
WHERE `region_id` =2
GROUP BY region_id
) AS ex ON B.region_id = ex.region_id
WHERE F.fse_category = 'Fse'
GROUP BY B.branch_id
) FSE ON FSE.region_id=E.region_id
WHERE E.region_id=2 GROUP BY k.branches
Notice you were doing a join after the other, and combining results that should be unique in your query. You'd joined the data from the query you named k, and then joined the result with the query you named BAL, that, except by the column balance, had the same entries, and so the branch_id's were being duplicated.
You had, in a quick:
k.branch_id LEFT JOIN BAL.branch_id
which caused your rows to be duplicated, with different balance values.
The result obtained with the query posted is:
REGION_ID STATUS0 STATUS1 DISCOUNT BRANCHES BRANCH_NAMES BALANCE TELECALLERS FSES
2 (null) 4 400 30 KOTTAKKAL 341 3 3
2 (null) 4 800 31 KALPETTA 394 3 3

Try This ::
IN your query just append the following part :
GROUP BY branch_names
OR you can get the DISTINCT in your SELECT part as :
Select DISTINCT(branch_names) from....
The final query will be ::
SELECT E.`region_id`,a0.status0,a1.status1,k.discount,k.branches
,k.branch_names,BAL.balance,TCLRS.telecallers,FSE.fses
FROM tbl_insurance_excel E
LEFT OUTER JOIN (Select E2.region_id, count(`id`) as status1
from tbl_insurance_excel E2 Left Join tbl_recipt_general_details on id=insurance_excel_id
JOIN tbl_branches on policy_closed_branch= branch_id
Where E2.`row_status` =1 AND E2.canceled_status='no' and E2.region_id=2 Group by region_id) a1 ON a1.region_id=E.region_id
LEFT OUTER JOIN (Select E2.region_id, count(`id`) as status0
from tbl_insurance_excel E2 Left Join tbl_recipt_general_details on id=insurance_excel_id
JOIN tbl_branches on policy_closed_branch= branch_id
Where E2.`row_status` =0 AND E2.canceled_status='no' and E2.region_id=2 Group by region_id) a0 ON a0.region_id=E.region_id
LEFT JOIN (
SELECT IEX.region_id,B.branch_name as branch_names,B.branch_id as branches, sum( DDT.discounts_amount ) as discount
FROM tbl_insurance_excel IEX
LEFT JOIN tbl_recipt_general_details RGD ON IEX.id = RGD.insurance_excel_id
LEFT JOIN tbl_discounts_details DDT ON RGD.rec_gene_id = DDT.recipt_general_id
LEFT JOIN tbl_branches B ON B.branch_id = RGD.policy_closed_branch
WHERE IEX.region_id =2
GROUP BY B.branch_id)k on k.region_id=E.region_id
LEFT JOIN (
SELECT IEX.region_id,B.branch_id as branches, sum( RGD.`recipt_bal_amount` ) AS balance
FROM tbl_insurance_excel IEX
LEFT JOIN tbl_recipt_general_details RGD ON IEX.id = RGD.insurance_excel_id
LEFT JOIN tbl_branches B ON B.branch_id = RGD.policy_closed_branch
WHERE IEX.region_id =2
GROUP BY B.branch_id)BAL ON BAL.region_id=E.region_id
LEFT JOIN (
SELECT ex.region_id, B.branch_id AS branches, count( F.`fse_id` ) AS telecallers
FROM tbl_branches B
LEFT JOIN tbl_team_leader L ON B.branch_id = L.leader_branch_id

LEFT JOIN tbl_fse F ON L.leader_id = F.leader_id

) AS ex ON B.region_id = ex.region_id

GROUP BY B.branch_id
) FSE ON FSE.region_id=E.region_id
where E.region_id=2 group by k.branches

Answer 3

did u try to wrap your query with another select and group it by BRANCH_NAMES
SELECT * FROM
(
<< your query goes here>>
) o
GROUP BY o.BRANCH_NAMES
But in case u put your results together like this, you will defnitely loose data in balance column.
