I have a database with 3 tables :
PM_FLX_ENTE
PM_ST
PM_ANO_SP
and I would like to get PM_ANO_SP.L_ANO_SP for certain values of PM_ANO_L.L_ANO which contains a code number with /.
SELECT COUNT(RF_INTRN),TRIM(pm_st.c_st),TRIM(pm_ano_l.L_ANO)
FROM PM_FLX_ENTE
INNER JOIN PM_ST ON PM_FLX_ENTE.C_ST = PM_ST.C_ST
INNER JOIN PM_ANO_L ON PM_FLX_ENTE.C_ANO = pm_ano_l.c_ano
WHERE pm_flx_ente.C_ANO <> '0000'
AND pm_ano_l.c_lang = 'FR'
group by TRIM(pm_st.c_st), TRIM(pm_ano_l.L_ANO)
ORDER BY COUNT(RF_INTRN) DESC
Can you help me please
It's a bit overkill, but if it's only Id in your PM_ANO_SP, then going straight for a join and working with what you get is a way :
SELECT
COUNT(RF_INTRN),
TRIM(NVL(PM_ANO_SP.L_ANO_SP, pm_st.c_st)), -- If found in PM_ANO_SP, use it
TRIM(pm_ano_l.L_ANO)
FROM PM_FLX_ENTE
INNER JOIN PM_ST
ON PM_FLX_ENTE.C_ST = PM_ST.C_ST
INNER JOIN PM_ANO_L
ON PM_FLX_ENTE.C_ANO = PM_ANO_L.C_ANO
LEFT JOIN PM_ANO_SP
ON PM_ST.C_ST = PM_ANO_SP.C_ST -- < Don't know the name
WHERE
pm_flx_ente.C_ANO <> '0000'
AND pm_ano_l.c_lang = 'FR'
GROUP BY TRIM(pm_st.c_st), TRIM(pm_ano_l.L_ANO)
ORDER BY COUNT(RF_INTRN) DESC
One option is to add yet another condition into WHERE clause:
and instr(PM_ANO_L.L_ANO, '/') > 0

Attempting to build SQL with INNER JOIN's. The INNER JOIN's work ok, now I need to add the MAX() function for limiting the rows to just most recent. Added this INNER JOIN client_diagnosis_record ON SELECT cr.PATID, cr.date_of_diagnosis, cr.most_recent_diagnosis...
Received this SQL code error, need some help, I'm sure it a simple oversight but my eyes are getting dim from looking so long...
Syntax error: [SQLCODE: <-4>:

I tried to re-format you query and it seems your query syntax is not correct. You may try below query -
SELECT pd.patient_name,
cr.PATID,
cr.date_of_diagnosis,
cr.EPISODE_NUMBER,
ce.diagnosing_clinician_value,
ce.data_entry_user_name,
most_recent_diagnosis

date_of_diagnosis) cr2 ON cr.PATID = cr2.PATID
AND cr.date_of_diagnosis = cr2.date_of_diagnosis
AND cr.ID = cr2.most_recent_diagnosis
INNER JOIN patient_current_demographics pd ON cr.patid = pd.patid
INNER JOIN client_diagnosis_entry ce ON ce.patid = pd.patid
AND cr.ID = ce.DiagnosisRecord
INNER JOIN RADplus_users ru ON ru.staff_member_id = ce.diagnosing_clinician_code

I want to extract a ID , User_ID value from one of the Companies and Contract tables, depending on the ContorollerName value.
select P.TitleProject, P.StartDateProject, P.EndDateProject,P.ControllerID,P.RecordID,P.IsAllocated,P.ProjectStatus_ID,
CN.ControllerName,CN.PersianName,
PU.ProjectID,PU.UserID,PU.RoleID,
CASE
WHEN CN.ControllerName = 'Company' THEN
Companies.Id,Companies.[User_Id]
WHEN CN.ControllerName = 'Contract' THEN
Contracts.Id,Contracts.[User_Id]
END
from Projects P
left outer join Controllers CN ON P.ControllerID = CN.Id
left outer join ProjectUsers PU ON P.Id = PU.ProjectID
where P.IsAllocated = 1
For example, if ContorollerName is 'Company' , the select command is as follows :
select P.TitleProject, P.StartDateProject, P.EndDateProject,P.ControllerID,P.RecordID,P.IsAllocated,P.ProjectStatus_ID,
CN.ControllerName,CN.PersianName,
PU.ProjectID,PU.UserID,PU.RoleID,
Companies.Id,Companies.[User_Id]
You are on the right track -- using left join. But you need to add the tables to the from clause with the appropriate logic.
The logic for the join is quite unclear. The query looks something like this:
select . . .,
coalesce(c.id, co.id) as id,
coalesce(c.user_id, co.user_id) as user_id
from Projects P left join
Controllers CN
on P.ControllerID = CN.Id left join
ProjectUsers PU
on P.Id = PU.ProjectID left join
companies c
on c.? = ? and -- no idea what the right join conditions are
c.ControllerName = 'Company' left join
contracts co
on co.? = ? and -- no idea what the right join conditions are
co.ControllerName = 'Contract'
where P.IsAllocated = 1
I have a pretty standard query for a back up aging report. What I want / need to do is have it report on missed back ups. I will need to see the last full database back up older than 2 days. I will also need to see any differential back ups older than the last day and any log back ups older than 30 mins. I'm not sure how to do the conditional where clause.
here's my basic query

Use a CASE statement. I'll paste an example from my own work:

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.
Edit: Deleted my old message cause it was confusing. And i can't answer my own question for now.
Found, problem come from GROUP BY.
After some researches, i found that we can't use GROUP BY for group a column inside grouped rows.
So this work as expected :
SELECT candidats.*
, AVG(test_results.rate_good_answer) AS toto
FROM "candidats"
LEFT JOIN "sessiontests"
ON "sessiontests"."candidat_id" = "candidats"."id"
LEFT JOIN "test_results"
ON "test_results"."sessiontest_id" = "sessiontests"."id"
LEFT JOIN "questionnaires"
ON "questionnaires"."id" = "test_results"."questionnaire_id"
WHERE (sessiontests.terminate = 't' )
AND ("questionnaires"."category" LIKE '%java%' )
GROUP BY candidats.id
ORDER BY toto
But this will grouped only my column in test_results :
SELECT candidats.*,
FROM "candidats"
LEFT JOIN "sessiontests"
ON "sessiontests"."candidat_id" = "candidats"."id"
LEFT JOIN "test_results"
ON "test_results"."sessiontest_id" = "sessiontests"."id"
LEFT JOIN "questionnaires"
ON "questionnaires"."id" = "test_results"."questionnaire_id"
WHERE (sessiontests.terminate = 't' )
AND ("questionnaires"."category" LIKE '%java%' )
GROUP BY candidats.id, test_results.rate_good_answer
ORDER BY AVG(test_results.rate_good_answer)
Edit 3 :
My problem was the second query was returning each different test_results row for my candidats, whereas i expected it to return me one line per candidat.
First query, is the answer, and it works nice.
SELECT candidats.*
, AVG(test_results.rate_good_answer) AS toto
FROM "candidats"
LEFT JOIN "sessiontests"
ON "sessiontests"."candidat_id" = "candidats"."id"
LEFT JOIN "test_results"
ON "test_results"."sessiontest_id" = "sessiontests"."id"
LEFT JOIN "questionnaires"
ON "questionnaires"."id" = "test_results"."questionnaire_id"
WHERE (sessiontests.terminate = 't' )
AND ("questionnaires"."category" LIKE '%java%' )
GROUP BY candidats.id
ORDER BY toto
