I have the following issue:
I have several tables in my Database, in order to check for a specific criteria I have to join several tables, where I use the following statement:
SELECT *
FROM (SELECT * FROM (((((((((SELECT * FROM table1 WHERE tab1_id = 1) AS A
INNER JOIN (SELECT * FROM table2 WHERE tab2_variable IS NOT NULL) AS B
ON A.variable = B.variable)
INNER JOIN (SELECT table3.*, IIF(year='XXXX', 0, 1) AS flag FROM table3) AS C
ON A.h_name = C.h_name)
INNER JOIN (SELECT * FROM table4 WHERE s_flag = 0) AS D
ON C.v_type = D.v_type)
INNER JOIN table5
ON C.ng_type = table5.ng_type)
INNER JOIN table6
ON C.part = table6.part)
INNER JOIN table7
ON C.ifg = table7.ifg)
INNER JOIN table8
ON C.v_type = table8.v_type AND C.ng_typ = table8.ng_typ AND C.ntr_flag = table8.ntr_flag)
INNER JOIN table9
ON table8.ifg_sii_id = table9.ifg_sii_id)) AS F
LEFT JOIN table10
ON F.risk = table10.risk AND C.v_type = table10.v_type
AND F.series = table10.series
This statement fails. But when I remove one the following two join-conditions in the last Left JOIN, it works as intended:
F.risk = table10.risk and/or C.v_type = table10.v_type
They are both of type CHAR, whereas series is type TINYINT, I guess it has something to do with joining on multiple conditions with strings, but I'm not able to find a workaround, any ideas?
according to your current SQL, Table C is not visible as it's a sub query within F. instead of C.v_type you need to use F.c_v_type and the c_v_type field must come from C table like. select v_type as c_v_type from table3... as C
In the last part of your Query You could try to actually select the table and include the Where Clause Like so:
LEFT JOIN (Select * from table10 Where C.v_type = v_type AND F.series = series) as xx
ON F.risk = xx.risk
Hope this helps

I have 2 selects. The first one:
select purs.t_orno as purchased
from ttisfc001201 sls
inner join twhinr110201 sfc on sfc.t_orno = sls.t_pdno
inner join twhltc100201 purs on purs.t_clot=sfc.t_clot
left join twhltc220201 items on items.t_clot = sfc.t_clot
left join twhltc210201 cert_num on cert_num.t_item = items.t_item
left join twhltc200201 cert on cert.t_ltft = cert_num.t_ltft
where sls.t_cprj = 'SLS004336' and purs.t_orno like N'PUR%'
and sfc.t_koor = 1 and sfc.t_kost = 5
Is giving me these results:
PUR007833
PUR008544
PUR008698
PUR008963
PUR009048
PUR009304
PUR009611
PUR009912
PUR009913
PUR010006
PUR010110
PUR010400
PUR010465
PUR010539
PUR010664
So basically these are results I must use in the second select in where clause. A field from table in second select must be equal to one of them. To understand me better it should look like this:
select distinct fac.t_isup
from ttfacp200201 fac
inner join ttfacp250201 mid on mid.t_ityp = fac.t_ttyp and mid.t_idoc=fac.t_ninv
where mid.t_orno ='PUR010400' or mid.t_orno='PUR009912'or mid.t_orno='PUR009913'or mid.t_orno='PUR010465'or mid.t_orno='PUR008544'or mid.t_orno='PUR008963'or mid.t_orno='PUR009048'or mid.t_orno='PUR010110'or mid.t_orno='PUR007833'or mid.t_orno='PUR009304'or mid.t_orno='PUR009611'or mid.t_orno='PUR010664'or mid.t_orno='PUR010006'or mid.t_orno='PUR010539'or mid.t_orno='PUR008698'or mid.t_orno='PUR010667'
All these ORs are results from the first select. How I can combine them (the first select to go in second select where clause) so I can get results at once?
You can use the IN clause for your second query
select distinct fac.t_isup
from ttfacp200201 fac
inner join ttfacp250201 mid on mid.t_ityp = fac.t_ttyp and mid.t_idoc=fac.t_ninv
where mid.t_orno IN (
select purs.t_orno
from ttisfc001201 sls
inner join twhinr110201 sfc on sfc.t_orno = sls.t_pdno
inner join twhltc100201 purs on purs.t_clot=sfc.t_clot
left join twhltc220201 items on items.t_clot = sfc.t_clot
left join twhltc210201 cert_num on cert_num.t_item = items.t_item
left join twhltc200201 cert on cert.t_ltft = cert_num.t_ltft
where sls.t_cprj = 'SLS004336' and purs.t_orno like N'PUR%'
and sfc.t_koor = 1 and sfc.t_kost = 5
)
Something like this
;with first_query_cte(purchased) as (
select purs.t_orno
from ttisfc001201 sls
inner join twhinr110201 sfc on sfc.t_orno = sls.t_pdno
inner join twhltc100201 purs on purs.t_clot=sfc.t_clot
left join twhltc220201 items on items.t_clot = sfc.t_clot
left join twhltc210201 cert_num on cert_num.t_item = items.t_item
left join twhltc200201 cert on cert.t_ltft = cert_num.t_ltft
where sls.t_cprj = 'SLS004336' and purs.t_orno like N'PUR%'
and sfc.t_koor = 1 and sfc.t_kost = 5)
select distinct fac.t_isup
from ttfacp200201 fac
inner join ttfacp250201 mid on mid.t_ityp = fac.t_ttyp and mid.t_idoc=fac.t_ninv
inner join first_query_cte fqc on mid.t_orno=fqc.purchased;

which gives me the following output
Now I want to use the above output values to select the rows from the table "YesNoAnswerWithObservation"
I imagine it should look something like this Select * from YesNoAnswerWithObservation Where Id in (22,27,26,...23)
Only instead of typing the values inside IN clause I want to use the values in each column resulting from above-mentioned query.
I tried the below code but it returns all the rows in the table rather than rows mentioned inside the In
SELECT pims.yesnoanswerwithobservation.observation,
graphitegtccore.yesnoquestion.description,
pims.yesnoanswerwithobservation.id ObservationId
FROM pims.yesnoanswerwithobservation

ON pims.icicimedicalexaminerreport.id =
pims.icicimerfemaleapplicant.id
WHERE pims.pimscase.tiannumber = 'ICICI1234567890')
Any help or a nudge in the right direction would be greatly appreciated
Presumably you want the ids from the first query:
SELECT awo.observation, ynq.description, ynq.id as ObservationId
FROM pims.yesnoanswerwithobservation awo JOIN
graphitegtccore.yesnoquestion ynq
ON awo.yesnoanswerid = ynq.id
WHERE ynq.id = (SELECT mer.id
FROM pims.pimscase c JOIN
pims.digitization d
ON c.digitizationid = d.id JOIN
pims.medicalexaminerreport mer
ON d.medicalexaminerreportid = mer.id JOIN
pims.icicimedicalexaminerreport imer
ON mer.id = imer.id JOIN
pims.icicimerfemaleapplicant ifa
ON imer.id = ifa.id
WHERE c.tiannumber = 'ICICI1234567890'
) ;
Notice that table aliases make the query much easier to write and to read.
I wanted to left join two queries:
First:
SELECT TIG_TOL.sName AS Maschine,
TIG_TOL.lTolRef,
Max(TIG_JOB.tActBegin) AS MaxvontActBegin
FROM TIG_JOB LEFT JOIN TIG_TOL ON TIG_JOB.lMacRef = TIG_TOL.lTolRef
WHERE (((TIG_JOB.sState)="Run" Or (TIG_JOB.sState)="Ready"))
GROUP BY TIG_TOL.sName, TIG_TOL.lTolRef;
Second:
SELECT TIG_JOB.sName AS Auftrag,
TIG_JOB.lJobRef,
TIG_TOL.sName AS Artikel,
TIG_TOL.sDescript AS Artikel_Bezeichnung
FROM (TIG_JOB LEFT JOIN TIG_TOL_BOK ON TIG_JOB.lJobRef = TIG_TOL_BOK.lJobRef)
LEFT JOIN TIG_TOL ON (TIG_TOL_BOK.lTolRef = TIG_TOL.lTolRef)
AND (TIG_TOL_BOK.lTolTypRef = TIG_TOL.lTolTypRef)
WHERE (((TIG_TOL.lTolTypRef)=10));
Over a left join
on First.MaxvontActBegin = Second.TIG_JOB.tActBegin
AND First.TIG_TOL.lTolRef = Second.TIG_JOB.lMacRef
Is that possible? In Access Im doing it over two queries, where the second is using the first..
I (blindly) added TIG_JOB.tActBegin and TIG_JOB.lMacRef to the 2nd SELECT (hoping they exist) in order to JOIN the two results.
I used SELECT * only because you did not specify the column selection.
SELECT *
FROM
(
SELECT TIG_TOL.sName AS Maschine,
TIG_TOL.lTolRef,
Max(TIG_JOB.tActBegin) AS MaxvontActBegin
FROM TIG_JOB LEFT JOIN TIG_TOL ON TIG_JOB.lMacRef = TIG_TOL.lTolRef
WHERE (((TIG_JOB.sState)="Run" Or (TIG_JOB.sState)="Ready"))
GROUP BY TIG_TOL.sName, TIG_TOL.lTolRef
) AS FirstTable
LEFT JOIN
(
SELECT TIG_JOB.sName AS Auftrag,
TIG_JOB.lJobRef,
TIG_TOL.sName AS Artikel,
TIG_TOL.sDescript AS Artikel_Bezeichnung,
TIG_JOB.tActBegin,
TIG_JOB.lMacRef
FROM (TIG_JOB LEFT JOIN TIG_TOL_BOK ON TIG_JOB.lJobRef = TIG_TOL_BOK.lJobRef)
LEFT JOIN TIG_TOL ON (TIG_TOL_BOK.lTolRef = TIG_TOL.lTolRef)

Below is my query using a left join that works as expected. What I want to do is add another table filter this query ever further but having trouble doing so. I will call this new table table_3 and want to add where table_3.rwykey = runways_updatable.rwykey. Any help would be very much appreciated.
SELECT *
FROM RUNWAYS_UPDATABLE
LEFT JOIN TURN_UPDATABLE
ON RUNWAYS_UPDATABLE.RWYKEY = TURN_UPDATABLE.RWYKEY
WHERE RUNWAYS_UPDATABLE.ICAO = 'ICAO'
AND (RUNWAYS_UPDATABLE.TORA > 4000 OR LDA > 0)
AND (TURN_UPDATABLE.AIRLINE_CODE IS NULL OR TURN_UPDATABLE.AIRLINE_CODE = ''
OR TURN_UPDATABLE.AIRLINE_CODE = '')
'*************EDIT To CLARIFY *****************
Here is the other statement that inner join i would like to use and I would like to combine these 2 statements.
SELECT *
FROM RUNWAYS_UPDATABLE A, RUNWAYS_TABLE B
WHERE A.RWYKEY = B.RWYKEY
'***What I have so far as advice taken below, but getting syntax error
SELECT RUNWAYS_UPDATABLE.*, TURN_UPDATABLE.*, AIRPORT_RUNWAYS_SELECTED.*
FROM RUNWAYS_UPDATABLE
INNER JOIN AIRPORT_RUNWAYS_SELECTED
ON RUNWAYS_UPDATABLE.RWYKEY = AIRPORT_RUNWAYS_SELECTED.RWYKEY
LEFT JOIN TURN_UPDATABLE
ON RUNWAYS_UPDATABLE.RWYKEY = TURN_UPDATABLE.RWYKEY
NOTE: If i comment out the inner join and leave the left join or vice versa, it works but when I have both of joins in the query, thats when im getting the syntax error.
I always come across this question when searching for how to make LEFT JOIN depend on a further INNER JOIN. Here is an example for what I am searching when I am searching for "using LEFT JOIN and INNER JOIN in the same query":
SELECT *
FROM foo f1
LEFT JOIN (bar b1
INNER JOIN baz b2 ON b2.id = b1.baz_id
) ON
b1.id = f1.bar_id
In this example, b1 will only be included if b2 is also found.
Remember that filtering a right-side table in left join should be done in join itself.
select *
from table1
left join table2
on table1.FK_table2 = table2.id
and table2.class = 'HIGH'
I finally figured it out. Thanks for all your help!!!
SELECT * FROM
(AIRPORT_RUNWAYS_SELECTED
INNER JOIN RUNWAYS_UPDATABLE
ON AIRPORT_RUNWAYS_SELECTED.RWYKEY = RUNWAYS_UPDATABLE.RWYKEY)
LEFT JOIN TURN_UPDATABLE ON RUNWAYS_UPDATABLE.RWYKEY = TURN_UPDATABLE.RWYKEY
Add your INNER_JOIN before your LEFT JOIN:
SELECT *
FROM runways_updatable ru
INNER JOIN table_3 t3 ON ru.rwykey = t3.rwykey
LEFT JOIN turn_updatable tu
ON ru.rwykey = tu.rwykey
AND (tu.airline_code IS NULL OR tu.airline_code = '' OR tu.airline_code = '')
WHERE ru.icao = 'ICAO'
AND (ru.tora > 4000 OR ru.lda > 0)
If you LEFT JOIN before your INNER JOIN, then you will not get results from table_3 if there is no matching row in turn_updatable. It's possible this is what you want, but since your join condition for table_3 only references runways_updatable, I would assume that you want a result from table_3, even if there isn't a matching row in turn_updatable.
EDIT:
As #NikolaMarkovinović pointed out, you should filter your LEFT JOIN in the join condition itself, as you see above. Otherwise, you will not get results from the left-side table (runways_updatable) if that condition isn't met in the right-side table (turn_updatable).
EDIT 2: OP mentioned this is actually Access, and not MySQL
In Access, perhaps it's a difference in the table aliases. Try this instead:
SELECT [ru].*, [tu].*, [ars].*
FROM [runways_updatable] AS [ru]
INNER JOIN [airport_runways_selected] AS [ars] ON [ru].rwykey = [ars].rwykey
LEFT JOIN [turn_updatable] AS [tu]
ON [ru].rwykey = [tu].rwykey
AND ([tu].airline_code IS NULL OR [tu].airline_code = '' OR [tu].airline_code = '')
WHERE [ru].icao = 'ICAO'
AND ([ru].tora > 4000 OR [ru].lda > 0)
If it is just an inner join that you want to add, then do this. You can add as many joins as you want in the same query. Please update your answer if this is not what you want, though
SELECT *
FROM RUNWAYS_UPDATABLE
LEFT JOIN TURN_UPDATABLE
ON RUNWAYS_UPDATABLE.RWYKEY = TURN_UPDATABLE.RWYKEY
INNER JOIN table_3
ON table_3.rwykey = runways_updatable.rwykey
WHERE RUNWAYS_UPDATABLE.ICAO = 'ICAO'
AND (RUNWAYS_UPDATABLE.TORA > 4000 OR LDA > 0)
AND (TURN_UPDATABLE.AIRLINE_CODE IS NULL OR TURN_UPDATABLE.AIRLINE_CODE = ''
OR TURN_UPDATABLE.AIRLINE_CODE = '')
I am not really sure what you want. But maybe something like this:
SELECT RUNWAYS_UPDATABLE.*, TURN_UPDATABLE.*
FROM RUNWAYS_UPDATABLE
JOIN table_3
ON table_3.rwykey = runways_updatable.rwykey
LEFT JOIN TURN_UPDATABLE
ON RUNWAYS_UPDATABLE.RWYKEY = TURN_UPDATABLE.RWYKEY
WHERE RUNWAYS_UPDATABLE.ICAO = 'ICAO'
AND (RUNWAYS_UPDATABLE.TORA > 4000 OR LDA > 0)
AND (TURN_UPDATABLE.AIRLINE_CODE IS NULL OR TURN_UPDATABLE.AIRLINE_CODE = ''
OR TURN_UPDATABLE.AIRLINE_CODE = '')
For Postgres, query planner does not guarantee order of execution of join. To Guarantee one can use #Gajus solution but the problem arises if there are Where condition for inner join table's column(s). Either one would to require to carefully add the where clauses in the respective Join condition or otherwise it is better to use subquery the inner join part, and left join the output.
I am trying to update a date in a table, based off of a MAX(date) in another table. To get the correct data to link up, I have to do 2 inner joins and 2 left outer joins.
I can select the correct data, it returns a Guid (PersonId) and the Date.
I have to use this information to update my original table. I am having trouble getting this to work, I still getting syntax errors.
update tblqualityassignments as assign
inner join tblrequirementteams as team on assign.guidmemberid = team.guidmemberid
set assign.dtmQAPCLed = dtmTaken
from
(

inner join tblrequirementteams as team on assign.guidmemberid = team.guidmemberid
inner join tblregisteredusercerts as reg on team.guidpersonid = reg.guidpersonid
left outer join tblcerttaken as certs on certs.guidcertid = reg.guidcertid

where types.intcerttypeid = 1
and assign.guidmemberid = team.guidmemberid

Assuming you are using SQL Server for this, then this should work:

left outer join tblcerttaken as certs
