I'm trying to pull results from a database (sql server 2005) which takes 4 tables:
Subscriber S, Member M, ClaimLines L, ClaimHistoryLines H
Query is as follows:
select S.SBSB_ID, M.MEME_NAME,
(CASE L.CLCL_ID WHEN '' THEN H.CLCL_ID ELSE L.CLCL_ID END) AS CLAIM_ID
FROM CMC_CDDL_CL_LINE L, CMC_MEME_MEMBER M LEFT OUTER JOIN CMC_CLDH_DEN_HIST H
ON H.MEME_CK = M.MEME_CK, CMC_SBSB_SUBSC S
WHERE
S.SBSB_ID = '120943270' AND
L.MEME_CK = M.MEME_CK AND
M.SBSB_CK = S.SBSB_CK
This query successfully pulls in the result rows from the ClaimLines L table but no results from the History table are shown. I'm not sure how to do this, any sql experts out there that can help would be great. -Thanks!
CMC_CDDL_CL_LINE L, CMC_MEME_MEMBER M LEFT OUTER JOIN CMC_CLDH_DEN_HIST H
don't mix obsolete implied join syntax with left join. They don't play well together. Use the correct ANSII standard join syntax. Infact stop using the obsolete syntax altogether.
This was a very silly mistake on my part. I neglected to think of using a UNION which solved my problem and allowed me to pull from both places into a single results set without creating massive duplicate rows. Glad someone pointed out the proper way to write sql using ANSII standards.
select S.SBSB_ID, M.MEME_NAME,
L.CLCL_ID AS CLAIM_ID
FROM
CMC_SBSB_SUBSC S INNER JOIN CMC_MEME_MEMBER M ON S.SBSB_CK = M.SBSB_CK
INNER JOIN CMC_CDDL_CL_LINE L ON L.MEME_CK = M.MEME_CK
WHERE
S.SBSB_ID = '120943270'
UNION
select S.SBSB_ID, M.MEME_NAME,
H.CLCL_ID AS CLAIM_ID
FROM
CMC_SBSB_SUBSC S INNER JOIN CMC_MEME_MEMBER M ON S.SBSB_CK = M.SBSB_CK
INNER JOIN CMC_CLDH_DEN_HIST H ON H.MEME_CK = M.MEME_CK
WHERE
S.SBSB_ID = '120943270'

I am fairly new to sql in general, and I am trying to work with a database which is extremely large. Now, on the website's examples, there is this query
SELECT m.chembl_id AS compound_chembl_id,
s.canonical_smiles,
r.compound_key,
NVL(TO_CHAR(d.pubmed_id),d.doi) AS pubmed_id_or_doi,
a.description AS assay_description, act.standard_type,
act.standard_relation,
act.standard_value,
act.standard_units,
act.activity_comment
FROM compound_structures s,
molecule_dictionary m,
compound_records r,
docs d,
activities act,
assays a,
target_dictionary t
WHERE s.molregno (+) = m.molregno
AND m.molregno = r.molregno
AND r.record_id = act.record_id
AND r.doc_id = d.doc_id
AND act.assay_id = a.assay_id
AND a.tid = t.tid
AND t.chembl_id = 'CHEMBL1827';
because of this (+) and this NVL I assumed it is Oracle. I am working on pgadmin4 and all my attempts at translating this after doing some research, resulted in errors. Example of my attempt and the error given bellow
SELECT m.chembl_id AS compound_chembl_id,

Could someone help me?
Don't mix the old, ancient implicit joins and explicit JOIN operator:
SELECT m.chembl_id AS compound_chembl_id,
s.canonical_smiles,
r.compound_key,
COALESCE(CAST(d.pubmed_id AS varchar),d.doi) AS pubmed_id_or_doi,
a.description AS assay_description,
act.standard_type,
act.standard_relation,
act.standard_value,
act.standard_units,
act.activity_comment
FROM compound_structures s
LEFT JOIN molecule_dictionary m ON s.molregno = m.molregno
JOIN compound_records r ON m.molregno = r.molregno
JOIN docs d ON r.doc_id = d.doc_id
JOIN activities act ON r.record_id = act.record_id
JOIN assays a ON act.assay_id = a.assay_id
JOIN target_dictionary t ON a.tid = t.tid
WHERE t.chembl_id = 'CHEMBL1827';
I hope I got the direction of the outer join correct - I haven't used that Oracle syntax for decades (note that even Oracle recommends to stop using it).
But the inner join on the following tables effectively turns that outer join back into an inner join - I don't think the Oracle syntax changes that (meaning: I think that attempt on an outer join in the original query was wrong to begin with). So maybe you can simplify the LEFT JOIN to a JOIN. I am not sure if that outer join actually makes sense in the Oracle query.
Consider:
SELECT
m.chembl_id AS compound_chembl_id,
s.canonical_smiles,
r.compound_key,
COALESCE((d.pubmed_id)::text, d.doi) AS pubmed_id_or_doi,
a.description AS assay_description,
act.standard_type,
act.standard_relation,
act.standard_value,
act.standard_units,
act.activity_comment
FROM
compound_structures s
INNER JOIN molecule_dictionary m ON s.molregno = m.molregno
INNER JOIN compound_records r ON m.molregno = r.molregno
INNER JOIN docs d ON r.doc_id = d.doc_id
INNER JOIN activities act ON r.record_id = act.record_id
INNER JOIN assays a ON act.assay_id = a.assay_id
INNER JOIN target_dictionary t ON a.tid = t.tid AND t.chembl_id = 'CHEMBL1827'
Rationale:
use standard, explicit joins everywhere; old school joins have been deprecated 20 years ago!
COALESCE() is more standard than NVL()
a LEFT JOIN followed by INNER JOINs that relate to columns coming for the left table is actually equivalent to INNER JOIN
I've given this relational scheme and following task:
Inner Join: Return a list of professors, which gives
'lehrveranstaltung' of the 'fachbereich' with the name 'informatik'.
* print 'vorname', 'ho_name', 'lv_name'
* output should sort surnames in ascending order and if they're the same in descending order
* identical lines should online shown once
now I came up with following query:
select distinct
v.vorname,
h.ho_name,
l.lv_name
--print wanted, only once
from
vorname v,
hochschulangehoeriger h,
lehrveranstaltung l
-- from these tables
inner join fachbereich f on f.fb_name = 'Informatik'
-- only the 'informatik' events
inner join prof_haelt_lv on l.lv_nr = pl.lv_nr
-- make sure 'lehrveranstaltung' is from a professor
inner join mitarbeiter mit on pl.pers_Nr = mit.pers_Nr
-- make sure dude is a prof
where
mit.ho_nr = h.ho_nr
and
mit.ho_nr = v.ho_nr -- give only names from prof
order by
2 asc,
3 desc; -- order rules
I think this works for me (can't test it properly). But when I look at it I'll wish that I came up for a bether solution since this looks kinda ugly and wrong for me.
Is there a bether way of doing this? (Have to use inner join)
Based on the table you have, you may use the following SQL statement
SELECT DISTINCT v.vorname,
h.ho_name,
l.lv_name
FROM vorname v
INNER JOIN hochschulangehoeriger h
ON v.ho_nr = h.ho_nr
INNER JOIN mitarbeiter m
ON m.ho_nr = h.ho_nr
INNER JOIN fachbereich f
ON f.fb_nr = m.fb_nr
AND f.fb_name = 'Informatik'
INNER JOIN lehrveranstaltung l
ON l.fb_nr = f.nb_nr
INNER JOIN professor p
ON p.pers_nr = m.pers_nr
INNER JOIN prof_haelt_lv pl
ON pl.pers_nr = p.pers_nr
AND pl.lv_nr = l.lv_nr
ORDER BY 2,
3 DESC;
Also, these section on your SQL, this has no connection to any table in your SQL
inner join fachbereich f on f.fb_name = 'Informatik'
-- only the 'informatik' events
you forgot the alias for prof_haelt_lv
inner join prof_haelt_lv on l.lv_nr = pl.lv_nr
-- make sure 'lehrveranstaltung' is from a professor
I know there ust be a few hundred of this similar post, but I have tried all the other ways in MS Access and still cannot get it to work.
So my working code is as follows
SELECT FVR.*, V.[Week Commencing], F.Date, V.Date
FROM FVR
INNER JOIN (F
INNER JOIN V ON (F.[Week Commencing] = V.[Week Commencing]) AND (F.GUID = V.GUID))
ON (FVR.GUID = V.GUID) AND (FVR.GUID = F.GUID)
My desired effect would be to show the Dates of the "F" table that have no entries in the "V"Table.
Sorry for being crpytic on the tables but it is for work. I thoght i had a good idead on how to do most of this.
any help would be amazing as I have been pulling my hair over this for a while now.
Cheers and thanks in advance.
Editing this to add in the full code as it will make more sense.
I basically have am unable to produce the Data range from F(Forecast) that Does not match in V(Visits) am trying to bring up a list of forecasted dates that have not been visited using the Week Commencing and GUID from both tables, The FVR table is just a table that holds the regional data matching up to the GUID. #Hogan I tried your way and ended up with syntax errors, I almost got somewhere and then lost it again. I thought I had a bit more knowledge of SQL than this.
Full code is as follows
SELECT FVR.*, [Visits].[Week Commencing], [Forecast].[Forecast Date], [Visits].Date
FROM ForecastVisitRegion
INNER JOIN ([Forecast] INNER JOIN [Visits] ON ([Forecast].[Week Commencing] = [Visits].[Week Commencing])
AND ([Forecast].GUID = [Visits].GUID)) ON (FVR.GUID = [Visits].GUID)
AND (FVR.GUID = [External - Forecast].GUID)
Thanks again

You need to use left joins:
SELECT FVR.*, V.[Week Commencing], NZ(V.Date,F.Date) as virtual_date
FROM FVR
LEFT JOIN F ON FVR.GUID = F.GUID
LEFT JOIN V ON FVR.GUID = V.GUID F.[Week Commencing] = V.[Week Commencing]
Not sure I understand why FVR is coming into the mix but you need a left Join.
Select F.*
from F
left join V on F.[Week Commencing] = V.[Week Commencing] AND F.GUID = V.GUID
where V.GUID is null
The left join ensures all the records (matched or not) from F are included in the result set. Then the where V.GUID is null removes the records where no match was found in V leaving you with the F records with no match.
Another approach would be to use the NOT EXISTS statement in the WHERE Clause
Select F.*
from F
where not exists (select * from V where F.[Week Commencing] = V.[Week Commencing] AND F.GUID = V.GUID)
I am building a complex select statement, and when one of my values (pcf_auto_key) is null it will not disipaly any values for that header entry.
select c.company_name, h.prj_number, h.description, s.status_code, h.header_notes, h.cm_udf_001, h.cm_udf_002, h.cm_udf_008, l.classification_code
from project_header h, companies c, project_status s, project_classification l
where exists
(select company_name from companies where h.cmp_auto_key = c.cmp_auto_key)
and exists
(select status_code from project_status s where s.pjs_auto_key = h.pjs_auto_key)
and exists
(select classification_code from project_classification where h.pcf_auto_key = l.pcf_auto_key)
and pjm_auto_key = 11
--and pjt_auto_key = 10
and c.cmp_auto_key = h.cmp_auto_key
and h.pjs_auto_key = s.pjs_auto_key
and l.pcf_auto_key = h.pcf_auto_key
and s.status_type = 'O'
How does my select statement look? Is this an appropriate way of pulling info from other tables?
This is an oracle database, and I am using SQL Developer.
Assuming you want to show all the data that you can find but display the classification as blank when there is no match in that table, you can use a left outer join; which is much clearer with explicit join syntax:
select c.company_name, h.prj_number, h.description, s.status_code, h.header_notes,
h.cm_udf_001, h.cm_udf_002, h.cm_udf_008, l.classification_code
from project_header h
join companies c on c.cmp_auto_key = h.cmp_auto_key
join project_status s on s.pjs_auto_key = h.pjs_auto_key
left join project_classification l on l.pcf_auto_key = h.pcf_auto_key
where pjm_auto_key = 11
and s.status_type = 'O'
I've taken out the exists conditions as they just seem to be replicating the join conditions.
If you might not have matching data in any of the other tables you can make the other inner joins into outer joins in the same way, but be aware that if you outer join to project_status you will need to move the statatus_type check into the join condition as well, or Oracle will convert that back into an inner join.

I am trying to join three tables using and inner join and have the contents of one change colour if an e-mail has been sent.
Below is my query
SELECT IIF(COUNT Holdsent.job)>0, #STD, #RED) AS Colour, jobs.job, jobs.jobstatus, jobs.client, jobs.logdate
FROM jobs INNER JOIN clients ON clients.client = jobs.client INNER JOIN holdsent ON holdsent.job = jobs.job
WHERE (jobs.jobstatus = 'HOLD' OR jobs.jobstatus = 'CLIHOLD')
Below is the error I receive
Expected lexical element not found: (missing ( in aggregate function
[Parsing Expression (column1 in the SELECT clause)] -- Location of
error in the SQL statement is:1 SELECT IIF(COUNT
Holdsent.job)>0,#STD, #RED) AS COLOUR,jobs.job,
jobs.jobstatus,jobs.client,jobs.logdate FROM jobs INNER JOIN clients
ON clients.client = jobs.client INNER JOIN holdsent ON holdsent.job =
jobs.job WHERE (jobs.jobstatus = 'HOLD' OR jobs.jobstatus =
'CLIHOLD')
I am new to SQL and can do basic queries, but am not clear on IIF. Thank you in advance for any help you can provide.
iif is a special function from MS Access, which SQL Server has started supporting with the most recent version. The correct SQL form is the case statement. An improved version of your query, written in standard SQL, is:
SELECT (case when COUNT(hs.job)>0 then #STD else #RED end) AS Colour,
j.job, j.jobstatus, j.client, j.logdate
FROM jobs j INNER JOIN
clients c
ON c.client = j.client INNER JOIN
holdsent hs
ON hs.job = j.job
WHERE j.jobstatus in ('HOLD', 'CLIHOLD')
Sorry, I didnt mock up test tables for this, but I think you want to subquery against your holdsent table to get the count value into the main query, then use three parameters in your IIF() function. I didnt make a test case, but I think this will suit your needs:
SELECT IIF((isnull(holdsentCount.jobCount,0)>0, #STD, #RED) AS Colour
, jobs.job
, jobs.jobstatus
, jobs.client
, jobs.logdate
FROM jobs
JOIN clients
ON clients.client = jobs.client
LEFT JOIN (select holdsent.job
, count(*) as jobCount
from holdsent
group by holdsent.job ) as holdsentCount
ON holdsentCount.job = jobs.job
WHERE (jobs.jobstatus = 'HOLD' OR jobs.jobstatus = 'CLIHOLD')
Also, wrap the holdsentCount.jobCount with isnull() so that it returns 0 if it isn't returned in the subquery.
EDIT: I dont know what '#STD' or '#RED' are so I left them as-is.
