I am trying to understand why the following two SQL statements give different results. The first works as expected, the second produces no records.
Select * from Jet.LayoutListItemEntity_Default itemDefault
Join Jet.LayoutListEntity b
on itemDefault.UiKey = b.UiKey
Left join (Select * from Jet.LayoutListItemEntity where DomainId =2) item
on itemDefault.BindingPath = item.BindingPath
where item.DomainId is null
and b.DomainId = 2
Select * from Jet.LayoutListItemEntity_Default itemDefault
Join Jet.LayoutListEntity b
on itemDefault.UiKey = b.UiKey
Left join Jet.LayoutListItemEntity item
on itemDefault.BindingPath = item.BindingPath
where item.DomainId is null
and item.DomainId = 2
and b.DomainId = 2
The primary difference is that one puts the item.DomainId = 2 at the end, instead of in it's own select. It seems to me they would produce the same results.

These conditions are mutually exclusive:
where item.DomainId is null
and item.DomainId = 2
item.DomainID can't simultaneously be NULL and 2
You can move the errant where criteria to the JOIN criteria:
Select * from Jet.LayoutListItemEntity_Default itemDefault
Join Jet.LayoutListEntity b
on itemDefault.UiKey = b.UiKey
Left join Jet.LayoutListItemEntity item
on itemDefault.BindingPath = item.BindingPath
and item.DomainId = 2
where item.DomainId is null
and b.DomainId = 2
Your WHERE criteria is messed up in the 2nd query -- to make those statements the same, move the and item_DomainId = 2 to the JOIN.
Select * from Jet.LayoutListItemEntity_Default itemDefault
Join Jet.LayoutListEntity b
on itemDefault.UiKey = b.UiKey
Left join Jet.LayoutListItemEntity item
on itemDefault.BindingPath = item.BindingPath and item.DomainId = 2
where item.DomainId is null
and b.DomainId = 2

This is my database
I'm trying to display "hello" and "wo" in the same column
My SQL statement:
SELECT
d.CampaignId, d.ClientID,
citn.ImagePath AS Thumbnail, cidi.ImagePath AS DetailImage
FROM
MasterData.CampaignImage AS d
INNER JOIN
MasterData.CampaignImage AS citn ON d.CampaignId = citn.CampaignId
AND d.ClientID = citn.ClientID
AND citn.ImageTypeId = 1
INNER JOIN
MasterData.CampaignImage AS cidi ON d.CampaignId = cidi.CampaignId
AND d.ClientID = cidi.ClientID
AND cidi.ImageTypeId = 2
The output:
But now I have 2 rows in my output, how can I combine these into just one row?
Simply do SELECT DISTINCT to skip duplicate rows.
I have some issues getting a full outer join to work in T-SQL. The left outer join part seems to be working okay, but the right outer join doesn't work as expected. Here's some sample data to test this on:
I have a table A with the following columns and data. The row marked with red is the row that cannot be found in table B.
And a second table B with the following columns and data. The rows marked with yellow are the rows that cannot be found in table A.
I am trying to join the tables using the following sql code:
select tableA.klientnr, tableA.uttakstype, tableA.uttaksnr, tableA.vareanr TableAItem,tableB.vareanr tableBitem, tableA.kvantum tableAquantity, tableB.totkvant tableBquantity
from tableA as tableA
full outer join tableB as tableB on tableA.klientnr=tableB.klientnr and tableA.uttakstype=tableB.uttakstype and tableA.uttaksnr=tableB.uttaksnr and tableA.vareanr=tableB.vareanr and tableB.IsDeleted=0
where tableA.UttaksNr=639779 and tableA.IsDeleted=0
The result of the sql is the following image. The row marked in red is the extra row from tableA that does show up, but I can't get the rows from table B to show up
Expected to have 2 extra rows
550 SA 639779 NULL 100059 NULL 0
550 SA 639779 NULL 103040 NULL 14
Later edit:
Would this be correct way to handle the full outer join where there's the header/line type of structure? Or can the query be optimized?

Filtering with full join is really tricky. Your where criteria are actually turning the full join into a left join.
You can do what you want by filtering before the join:
select a.klientnr, a.uttakstype, a.uttaksnr, a.vareanr a.tableAitem,
b.vareanr b.tableBitem, a.kvantum a.tableAquantity, b.totkvant b.tableBquantity
from (select a.*
from tableA a
where a.UttaksNr = 639779 and a.IsDeleted = 0
) a full join
(select b.*
from tableB b
where b.IsDeleted = 0
) b
on a.klientnr = b.klientnr and
a.uttakstype= b.uttakstype and
a.uttaksnr = b.uttaksnr and
a.vareanr = b.vareanr;
I want to get fields from 2 different tables . The last field candidate_score_id has a many to one relationship. So how should I join the below 2 queries
1) To get candidate_score_id from the candidate_score table.
select candidate_score_id from candidate_score a where
a.assessment_id = NEW.assessment_id and
a.candidate_id = NEW.candidate_id and
a.attempt_Count = NEW.attempt_count;
2) To insert different fields in to the candidate_score_details table. The field in this table should be obtained by query above.
insert into candidate_score_details(candidate_score_details_id, candidate_id, assessment_id, attempt_count, score_type, score_tag,correct, candidate_score_id)
select uuid();
select a.candidate_id, a.assessment_id,a.attempt_count,"BY-COMPLEXITY",
case c.complexity
when 1 then "HIGH"
when 2 then "MEDIUM"
when 3 then "LOW"
end, count(*) from candidate_answer a, answer_key b, question_meta_data c where a.candidate_id = NEW.candidate_id and
a.assessment_id = NEW.assessment_id and
a.attempt_count = NEW.attempt_count and
a.assessment_id = b.assessment_id and
a.question_id = b.question_number and
a.response = b.answer and
a.question_id = c.question_number
group by a.candidate_id, a.assessment_id, a.attempt_count, c.complexity;
Just looking at the SQL joining aspect of your question, you'll need to specify the table I THINK you're aliasing a 2nd table with the "NEW" reference. If that's the case, then the query would be (replacing "OTHER_TABLE_NAME" with the name of the 2nd table:
select a.candidate_score_id
from candidate_score a
left join OTHER_TABLE_NAME new on
and a.assessment_id = NEW.assessment_id
and a.candidate_id = NEW.candidate_id
and a.attempt_Count = NEW.attempt_count
Seems that Query 1 has the same 3 criteria on the "candidate_score" table as for the "candidate_answer" table in Query 2.
So how about adding a LEFT JOIN of "candidate_score" to "candidate_answer" on those 3 fields?
For example:
INSERT INTO candidate_score_details
(
candidate_score_details_id,
candidate_id,
assessment_id,
attempt_count,
score_type,
score_tag,
correct,
candidate_score_id
)
SELECT
uuid(),
answer.candidate_id,
answer.assessment_id,
answer.attempt_count,
'BY-COMPLEXITY' AS score_type,
(CASE meta.complexity
WHEN 1 THEN 'HIGH'
WHEN 2 THEN 'MEDIUM'
WHEN 3 THEN 'LOW'
END) AS score_tag,
COUNT(*) AS correct,
MAX(score.candidate_score_id) AS max_candidate_score_id
FROM candidate_answer AS answer
JOIN answer_key AS akey
ON (akey.assessment_id = answer.assessment_id AND akey.question_number = answer.question_id AND akey.answer = answer.response)
LEFT JOIN candidate_score AS score
ON (score.candidate_id = answer.candidate_id AND score.assessment_id = answer.assessment_id AND score.attempt_count = answer.attempt_count)
LEFT JOIN question_meta_data AS meta
ON meta.question_number = answer.question_id
WHERE answer.candidate_id = NEW.candidate_id
AND answer.assessment_id = NEW.assessment_id
AND answer.attempt_count = NEW.attempt_count
GROUP BY answer.candidate_id, answer.assessment_id, answer.attempt_count, meta.complexity;
Hi i have joined to tables the code is below. Notice I have used A.Manad = B.Manad which joins data where the month of table A and B is equal. But sometimes table B dont have any data for that month. My code just skip the data, i would rather it just leave it empty or with a value of 0.
The Code takes a list of Orgnr which is swedish for company numbers and joins two tables where the orgnr is the same and the month is the same, but for some reason it doesnt join the data when the value is empty for one company. I still want the orgnr to show up in the joint table.
select Tillnr = A.tillnr, Orgnr = A.orgnr, Månad = A.Manad, Intrastat =
A.varde,Moms = B.vardeutf
into #Tabell1
From
IntrastatFsum A
left outer join
Momsuppg B
on A.Orgnr = B.Orgnr
where A.Orgnr in(
165563137933,165020456017,.......)
AND A.Ar = 2017
AND B.Ar = A.AR
AND A.Manad = 9
AND A.Manad = B.Manad
AND A.InfUtf = 'U'
You should move your WHERE clause AND A.Manad = B.Manad and AND B.Ar = A.AR to the LEFT JOIN clause.
In this way you will preserve all data from table IntrastatFsum:
select Tillnr = A.tillnr, Orgnr = A.orgnr, Månad = A.Manad, Intrastat =
A.varde,Moms = B.vardeutf
into #Tabell1
From
IntrastatFsum A
left outer join
Momsuppg B
on A.Orgnr = B.Orgnr
AND A.Manad = B.Manad
AND A.AR = B.Ar
where A.Orgnr in(
165563137933,165020456017,.......)
AND A.Ar = 2017
AND A.Manad = 9
AND A.InfUtf = 'U'
I have two tables and want to get technology_tag from table b based on reference id from table a:
select b.dbid, b.technology_tag
from tblConnect a, tblSites b
where a.Site_DBID = 2
and a.Related_Site_DBID = 1
and (b.dbid = a.bsc_tag_dbid or b.dbid = a.related_bsc_dbid or b.dbid = a.related_msc_dbid)
What I want to have here is to order the returned rows based on first occurrence (in where clause)
1st- b.dbid = a.bsc_tag_dbid
2cnd- b.dbid = a.related_bsc_dbid
3rd- b.dbid = a.related_msc_dbid
Does anyone has a clue how to do that?
First, you should switch to using actual JOIN clauses when performing joins. That said, this ORDER BY clause should do what you want:
SELECT
B.dbid,
B.technology_tag
FROM tblConnect A
INNER JOIN tblSites B ON
B.dbid IN (A.bsc_tag_dbid, A.related_bsc_dbid, A.related_msc_dbid)
WHERE
A.Site_DBID = 2 AND
A.Related_Site_DBID = 1
ORDER BY
CASE
WHEN B.dbid = A.bsc_tag_dbid THEN 1
WHEN B.dbid = A.related_bsc_dbid THEN 2
WHEN B.dbid = A.related_msc_dbid THEN 3
ELSE 4 -- Not really necessary, but I always use an ELSE when I use CASE
END
