Teradata to Oracle Query eaxdata Conversion - oracle

I need help with converting the below SQL query in Taradata to Oracle exadata. Not sure how to convert the date, I changed the CAST date function To_Date but get a few errors.
SELECT DISTINCT
pat.pat_id,
pat.pat_mrn_id AS patientmrn,
pat.pat_name AS patientname,

extract(year FROM acct.adm_date_time)-extract(year FROM
pat.birth_date) - CASE WHEN acct.adm_date_time (format
'MMDD')CHAR(4))
<pat.birth_date (format 'MMDD') (CHAR(4)) THEN 1 ELSE 0
END AS patage,

AND description LIKE '%CULTURE%'
AND ordproc.lab_status_c = 3
AND adt_pat_class_c IN ('1204','12113')
AND result_time > patenc.hosp_disch_time;
I changed the top part of the query(one with dates) -
select distinct
pat.pat_id,
pat.PAT_MRN_ID as PatientMRN,
pat.PAT_NAME as PatientName,
ADT_PAT_CLASS_C,
pat.DEATH_DATE as DeathDate,
TO_DATE(patenc.HOSP_ADMSN_TIME, 'mm/dd/yyyy') as AdmitDate,
TO_DATE(patenc.HOSP_DISCH_TIME, 'mm/dd/yyyy') as DischargeDate----
I get the below errors -

using subquery factoring result in where clause

Why can't I use a subquery factoring clause result in the where clause of as depicted in the following sql:
with rpt as(
select * from reports where caseid =
:case_id and rownum=1 order by created desc
)
select
distinct rt.trialid
from
report_trials rt
join
trial_genes tg on rt.id=tg.trialid
where
rt.reportid = rpt.id
and
tg.gene not in('TMB','MS')
The subquery is named rptand used in the select statement's where clause. When executed encountering the following error: ORA-00904: "RPT"."ID": invalid identifier
UPDATE:
In fact nested query for the same thing is also giving me the same issue. The nested subquery is only returning a single column value from a single row:
select
distinct rt.trialid
from
report_trials rt
join
trial_genes tg on rt.id=tg.trialid
where
rt.reportid = (select id from reports where caseid = :case_id and
rownum=1 order by created desc)
and
tg.gene not in('TMB','MS')
You missed to add the table rpt in your query, thus that error.
with rpt as(
select * from reports where caseid =
:case_id and rownum=1 order by created desc
)
select
distinct rt.trialid
from
report_trials rt
join
trial_genes tg on rt.id=tg.trialid
join
rpt on rt.reportid = rpt.id
where
tg.gene not in('TMB','MS')

SQL Query using Joins: ORA-00979 error [duplicate]

This question already has answers here:
ORA-00979 not a group by expression
(10 answers)
Closed 5 years ago.
I'm trying to execute one sql query using joins, but I'm getting the below error:
ORA-00979: not a GROUP BY expression
00979. 00000 - "not a GROUP BY expression"
The query is to count the number of normalized_event_ids along with the error message and error_ids using two tables.:
select count(nee.normalised_event_id),
em.error_message,
em.error_message_id
from normalised_event_error nee, error_message em
where nee.charge_start_date >= to_date('01-07-2017','DD-MM-YYYY')
and nee.error_message_id = em.error_message_id
group by em.error_message;
SELECT COUNT (nee.normalised_event_id), em.error_message, em.error_message_id
FROM normalised_event_error nee
INNER JOIN error_message em
ON nee.error_message_id = em.error_message_id
WHERE nee.charge_start_date >= TO_DATE ('01-07-2017', 'DD-MM-YYYY')
GROUP BY em.error_message, em.error_message_id;
The select columns and group by columns must be same for grouping.
Example
You need to add error_message_id column to the group by clause:
SELECT COUNT(nee.normalised_event_id) as messages,
em.error_message,
em.error_message_id
FROM normalised_event_error nee
JOIN error_message em ON em.error_message_id = nee.error_message_id
WHERE nee.charge_start_date >= to_date('01-07-2017','DD-MM-YYYY')
GROUP BY em.error_message, em.error_message_id;
Try this:
SELECT
em.error_message,
em.error_message_id,
count(nee.normalised_event_id)
from normalised_event_error nee,
error_message em
where nee.charge_start_date >= to_date('01-07-2017','DD-MM-YYYY')
and nee.error_message_id = em.error_message_id
group by em.error_message, em.error_message_id;

Any idea?
Your error states the ILLEGAL USE OF KEYWORD OF. TOKEN [DESC ASC NULLS RANGE CONCAT] WAS EXPECTED.
I identified this as the critical part of the query:
ORDER BY ORDER OF inner2_
DB2 expects one of DESC, ASC, NULLS, RANGE, CONCAT after the second ORDER keyword.
This issue can be resolve by change dialect.
Change dialect in configuration or property file to DB2ZOSDialect

Need to Include a Name with Group By oracle sql

I have some Code here,
`SELECT a.Officer_ID, Count(Crime_ID)
FROM Officers a inner Join Crime_Officers b on a.Officer_ID = b.Officer_ID
Group by a.Officer_ID
Having (Count(Crime_ID) > (select avg(distinct(Count(Crime_ID)))
From Crime_Officers
Group by officer_Id));`
it outputs this,
`OFFICER_ID COUNT(CRIME_ID)
---------- ---------------
111115 9 `
Its cool and all, but my assignment only needs the officers last name which is in table A. I tried it with the Officer_ID and Count just to make sure the code was working. When I try it like this,
`SELECT Last
FROM Officers a inner Join Crime_Officers b on a.Officer_ID = b.Officer_ID
Group by a.Officer_ID
Having (Count(Crime_ID) > (select avg(distinct(Count(Crime_ID)))
From Crime_Officers
Group by officer_Id));`
I get this error,
`Error starting at line 1 in command:
SELECT Last
FROM Officers a inner Join Crime_Officers b on a.Officer_ID = b.Officer_ID
Group by a.Officer_ID
Having (Count(Crime_ID) > (select avg(distinct(Count(Crime_ID)))

Error report:
SQL Error: ORA-00979: not a GROUP BY expression

Can anyone help or explain what I'm missing/Doing wrong?
You can only select a column if a) it's in the GROUP BY, b) it's derived from a GROUP BY column or c) it's the result of an aggregate function like MAX/MIN.
In your case, each Officer_ID should only have one Last value.
Simply change your GROUP BY to read:
GROUP BY a.Officer_ID, a.Last

Does Oracle implicit conversion depend on joined tables or views

I've faced with a weird problem now. The query itself is huge so I'm not going to post it here (I could post however in case someone needs to see). Now I have a table ,TABLE1, with a CHAR(1) column, COL1. This table column is queried as part of my query. When I filter the recordset for this column I say:
WHERE TAB1.COL1=1
This way the query runs and returns a very big resultset. I've recently updated one of the subqueries to speed up the query. But after this when I write WHERE TAB1.COL1=1 it does not return anything, but if I change it to WHERE TAB1.COL1='1' it gives me the records I need. Notice the WHERE clause with quotes and w/o them. So to make it more clear, before updating one of the sub-queries I did not have to put quotes to check against COL1 value, but after updating I have to. What feature of Oracle is it that I'm not aware of?
EDIT: I'm posting the tw versions of the query in case someone might find it useful

I've put separating comments for the changed subqueries and the WHERE clause in both queries. Both versions of the subqueries return the same result, one of them is just slower, which is why I decided to update it.
With the most simplistic example I can't reproduce your problem on 11.2.0.3.0 or 11.2.0.1.0.
SQL> create table tmp_test ( a char(1) );
Table created.
SQL> insert into tmp_test values ('1');
1 row created.
SQL> select *
2 from tmp_test
3 where a = 1;
A
-
1
If I then insert a non-numeric value into the table I can confirm Chris' comment "that Oracle will rewrite tab1.col1 = 1 to to_number(tab1.col1) = 1", which implies that you only have numeric characters in the column.
SQL> insert into tmp_test values ('a');
1 row created.
SQL> select *
2 from tmp_test
3 where a = 1;

ORA-01722: invalid number

If you're interested in tracking this down you should gradually reduce the complexity of the query until you have found a minimal, reproducible, example. Oracle can pre-compute a conversion to be used in a JOIN, which as your query is complex seems like a possible explanation of what's happening.
Oracle explicitly recommends against using implicit conversion so it's wiser not to use it at all; as you're finding out. For a start there's no guarantees that your indexes will be used correctly.
Oracle recommends that you specify explicit conversions, rather than rely on implicit or automatic conversions, for these reasons:
SQL statements are easier to understand when you use explicit data type conversion functions.
Implicit data type conversion can have a negative impact on performance, especially if the data type of a column value is converted to that of a constant rather than the other way around.
Implicit conversion depends on the context in which it occurs and may not work the same way in every case. For example, implicit conversion from a datetime value to a VARCHAR2 value may return an unexpected year depending on the value of the NLS_DATE_FORMAT
parameter.
Algorithms for implicit conversion are subject to change across software releases and among Oracle products. Behavior of explicit conversions is more predictable.
If you do only have numeric characters in the column I would highly recommend changing this to a NUMBER(1) column and I would always recommend explicit conversion to avoid a lot of pain in the longer run.
It's hard to tell without the actual query. What I would expect is that TAB1.COL1 is in some way different before and after the refactoring.
Candidates differences are Number vs. CHAR(1) vs. CHAR(x>1) vs VARCHAR2
It is easy to introduce differences like this with subqueries where you join two tables which have different types in the join column and you return different columns in your subquery.
To hunt that issue down you might want to check the exact datatypes of your query. Not sure how to do that right now .. but an idea would be to put it in a view and use sqlplus desc on it.
