I need to add two my tables into that script with right way that means If I mapped one of them then the normal row count increases this makes me crazy, I have been trying to solve that issue for a couple days but I had been fail many times.
I couldn't find a good mapped fields between stok47t and the others. But there are still a few columns(fields) matches for their types and data.
I need to listen ppl opinions and learns something.
Here is a big part of my query
If you are getting increase in row count then chances are it could be due to using LEFT JOIN. An INNER join might help (see http://www.codinghorror.com/blog/2007/10/a-visual-explanation-of-sql-joins.html guidance)
SELECT a.acikkapali,
b.onay, b.evrakno,
b.tarih,
a.kod,
d.ad,
a.note0,
a.sf_miktar,
a.sf_sf_unit,
a.rtalepedilentestarih,
c.evrakno
FROM stok47T a
INNER JOIN stok47e b on a.evrakno = b.evrakno
INNER JOIN stok46t1 c on a.evrakno = c.talepno
INNER JOIN stok00 d on a.kod = d.kod
WHERE a.tarih = '2013/04/15'
However without understanding your data structure then there is a chance you might lose the information that you are after.
If you are getting multiple rows, it is probably due to a Cartesian product occurring in the joins. This is unrelated to the type of join (left/right/full/inner). It is based on the relationships between the tables. You have 1-N relationships along different dimensions.
Your conditions are:
FROM stok47T a
LEFT JOIN stok47e b on a.evrakno = b.evrakno
LEFT JOIN stok46t1 c on a.evrakno = c.talepno
LEFT JOIN stok00 d on a.kod = d.kod
I have no idea what these tables and fields mean. But, if you have a case where there is one row per evrakno in table stok47t, and there are two rows in table stok47e and three in table stok46t1, then you will get six rows in the output.
Without more information, it is impossible to tell you the best solution. One method is to summarize the tables. Another is to take the first or last corresponding row, by doing something like:
from stok47T a left join
(select s.*, row_number() over (partition by evrakno order by id desc) as seqnum
from stok47e s
) b
on a.evrakno = b.evrakno and b.seqnum = 1

in query here i have https://www.db-fiddle.com/f/32Kc3QisUEwmSM8EmULpgd/1
SELECT p.prank, d.dare
FROM dares d
INNER JOIN pranks p ON p.id = d.prank_id
WHERE d.condo_id = 1;
i have one condo with id 1 and it have unique connection to dares that has connection to pranks and unique connection to condos_pranks
and i wanna have all unique pranks from both tables and i used this query above to get relation of
dares to pranks and expected result was L,M,N - Yes,No,Maybe and it is correct but i also wanna have those in condos_pranks which ids are 1,4,5,6 = L,O,P,Q
so i tried to join the table with left join because it might not have condos_pranks row
SELECT p.prank, d.dare
FROM dares d
INNER JOIN pranks p ON p.id = d.prank_id
LEFT JOIN condos_pranks pd ON pd.condo_id = d.condo_id AND pd.prank_id = p.id
WHERE d.condo_id = 1;
but result is same as first and what i want is
prank
dare
L
Yes
M
No
N
Maybe
O
No
P
No
Q
No
with default being No = 2 if prank_id of condos_pranks is not in dares
how to connect it?
This seems like an exercise in identifying extraneous information more than anything. You are unable to join something to a table that has no key, however if you know your default then you may use something like coalesce to identify the records where there was no data to join NULL and replace them with your default.
I mentioned in a comment above that this table schema makes little sense. You have keys all over the place that doing have all sorts of circular references. If this is your derived schema, consider stopping here and revisiting the relationships. If it is not and it is something educational, which I suspect it is, disregard and recognize the logical flaws in what you are working in. Perhaps consider taking the data provided and creating a new table schema that is more normalized and uses other tables to handle the many to many and one to many relationships.
dbfiddle
SELECT
pranks.prank,
COALESCE(dares.dare, 'No')
FROM pranks LEFT OUTER JOIN
dares ON pranks.id = dares.prank_id
ORDER BY pranks.prank ASC;
clearlyclueless gave correct explanations
To achieve the result, the following SELECT can also be used:
SELECT
pranks.prank,
case
when dare is null then 'No'
else dare
end
FROM pranks LEFT OUTER JOIN
dares ON pranks.id = dares.prank_id
I'm populating a table which is fetching the ids from 2 other tables to display their information, for example, delivery has a Hamburguer and the box, but the user might register the delivery with out the box, only with the hamburguer.
When I make a INNER JOIN SELECT to get the data from the DB it will return 0 results since there is no box and I'm trying to compare the ids that don't exist. It doesn't populate the table then.
SELECT
entrega_telemovel.*,
telemovel.id_telemovel,
telemovel.nroserie,
nro_telemovel.numero_telemovel,
nro_telemovel.id_nrotelemovel,
funcionarios.id_funcionario,
funcionarios.nome
FROM entrega_telemovel
INNER JOIN telemovel
ON entrega_telemovel.telemovel = telemovel.id_telemovel
INNER JOIN nro_telemovel
ON nro_telemovel.id_nrotelemovel = entrega_telemovel.numero_telemovel
INNER JOIN funcionarios
ON funcionarios.id_funcionario = entrega_telemovel.funcionario_entrega
ORDER BY funcionarios.nome;
In this query above entrega_telemovel.telemovel=telemovel.id_telemovel the value in entrega_telemovel.telemovel is null like the example I gave above. So 0 results are returned from the query.
How can I solve this ?
You are looking for a LEFT JOIN.
INNER JOIN only combines rows, that exist in both tables. A LEFT JOIN on the other hand always produces at least one row. If on table does not have a match for it, all columns are set to NULL.
SELECT
entrega_telemovel.*,
telemovel.id_telemovel,
telemovel.nroserie,
nro_telemovel.numero_telemovel,
nro_telemovel.id_nrotelemovel,
funcionarios.id_funcionario,
funcionarios.nome
FROM entrega_telemovel
LEFT JOIN telemovel
ON entrega_telemovel.telemovel = telemovel.id_telemovel
LEFT JOIN nro_telemovel
ON nro_telemovel.id_nrotelemovel = entrega_telemovel.numero_telemovel
LEFT JOIN funcionarios
ON funcionarios.id_funcionario = entrega_telemovel.funcionario_entrega
ORDER BY funcionarios.nome;
You want to show all entrega_telemovel entries, no matter whether they have a match in entrega_telemovel or not. This is what an outer join does.
SELECT ...
FROM entrega_telemovel et
LEFT OUTER JOIN telemovel t ON et.telemovel = t.id_telemovel
...
What I'm looking to generate is the wp_tylerposts table as it is, with the same specifications as the query (selecting only those with post_type='sponsor', but I'd like to reference the other two tables (object_id from wp_tylerterm_relationships and the corresponding name from wp_tylerterms) so that added on to wp_tylerpostswould be the corresponding name value from wp_tylerterms (added to the table would be "Gold Sponsors", for example).
Hopefully that makes sense. I'm sure there's a pretty simple solution, and I've tried my hand at some join queries without any luck... haven't done any of the stuff in a long time. Any help would be much appreciated!
Edit: I've come closer, I think, but I still can't retrieve the "name" column value from wp_tylerterms, here's what I have:
SELECT
c.ID, c.post_title, a.name
FROM
wp_tylerposts c
LEFT JOIN
wp_tylerterm_relationships b
ON
c.ID = b.object_id
LEFT JOIN
wp_tylerterms a
ON
b.object_id = a.term_id
WHERE
c.post_type = 'sponsor'
In second join, you use b.object_id instead of b.term_taxonomy_id. Your query should look like this:
SELECT
c.ID, c.post_title, a.name
FROM
wp_tylerposts c
LEFT JOIN
wp_tylerterm_relationships b
ON
c.ID = b.object_id
LEFT JOIN
wp_tylerterms a
ON
b.term_taxonomy_id = a.term_id
WHERE
c.post_type = 'sponsor'
SELECT distinct t1.vssyspackageid,CA.rAmount as Amount,Curr.vsShortCode AS Currency
from tblPrograms
INNER JOIN tblProgramsAndPackages ON tblPrograms.vsSysProgramId = tblProgramsAndPackages.vsSysProgramId
inner join tblPackages t1 on tblProgramsAndPackages.iPackageId=t1.iPackageId
right join tblPkgContractAwardDetails as CA on CA.iPackageId=t1.iPackageId
join tblCurrencies as Curr on CA.iCurrency =Curr.iCurrencyId
where tblPrograms.vsSysProgramId='JICA'
group by t1.vssyspackageid,CA.rAmount,Curr.vsShortCode
if which package assigned to Contractor Award Detail then it will show in one column.
Example: GWSSP/01,GWSSP/02 then after it it shows total package in next column.
I'm not sure exactly what you are wanting as your question is a little vague, but I'm guessing that you want a single row for the specified Package that will show the sum of the Amount column. This is what I can understand from your question anyway!
SELECT DISTINCT t1.vssyspackageid,
SUM(CA.rAmount) AS TotalAmount,
Curr.vsShortCode AS Currency
FROM tblPrograms
INNER JOIN tblProgramsAndPackages ON tblPrograms.vsSysProgramId =
tblProgramsAndPackages.vsSysProgramId
INNER JOIN tblPackages AS t1 ON tblProgramsAndPackages.iPackageId =
t1.iPackageId
RIGHT JOIN tblPkgContractAwardDetails AS CA ON CA.iPackageId =
t1.iPackageId
JOIN tblCurrencies AS Curr ON CA.iCurrency =
Curr.iCurrencyId
WHERE tblPrograms.vsSysProgramId = 'JICA'
AND t1.[YOUR_COLUMN_NAME_HERE] = 'GWSSP/01'
GROUP BY t1.vssyspackageid,
Curr.vsShortCode
Just a few things to note:
I don't know the column name in the tblPackages table that the values such as 'GWSSP/01' belongs, so I have left that for you to fill in.
You will still get multiple rows if there are multiple currencies for your package, you will have to remove the Curr.vsShortCode from your Select and Group By clauses if that is the case.
I also tided up your code a bit because it was quite messy and hard to understand as well as using multiple standards and short-cuts!
I was desperately trying harder and harder to get this thing done but didn`t yet succeed. I am getting repeated values when i run this query.

I have also attached a picture of my result set of rows.
Any suggestions why this is happening would really be appreciable.
Result Set
Typically this happens when you have an implicit partial cross join (Cartesian product) between two of your tables. That's what it looks like to me here.
This happens most often when you have a many-to-many relationship. For example, if a single Album allows both multiple Artists and multiple Songs and the only relationship between Artists and Songs is Album, then there's essentially a many-to-many relationship between Artists and Songs. If you select from all three tables at once you're going to implicitly cross join Artists and Songs, and this may not be what you want.
Looking at your query, I see many-to-many between Tbl_CountDetail and tbl_Comission through Tbl_Contract. Try eliminating one of those joins to test to see if the behavior disappears.
Try using the DISTINCT keyword. It should solve your issue
Select DISTINCT ....
Wait as far as I can see your records are not duplicates.
HOWEVER
Notice the CountName column and Shipment ID column
The combination is unique for every row. Hence the values are unique as far as I can see. Try not selecting CountName.
Well if you have distinct rows its not a duplication problem. The issue is during the join a combination is occurring you don't want it to duplicating the results.
Either don't select CountName or you have a mistake in your data.
Only one of those rows should be true either 6 with Count2 or 6 with Count1. Likewise for 7. The fact that your getting both when your not supposed to indicates a logic mistake
