Team,
I have an issue here, have 2 temporary table a & b with value as 5 & 6 for the respective column like a.ref1 & b.ref2.
I am trying to get these values into another SQL like
"select c.col1, d.col1,d.col2 from c join d on a.id=d.id where d.col1=(schema_name).a.ref1 or
d.col2=(schema_name).b.ref2"
I get error like
"Invalid table alias or column reference "
. any thoughts, why it behaving like this. I tried with select query to pass the temp table values but this does not work in hive .Any further assistance would be appreciated
You you can do this by using something called Common Table Expression, This will make your query perform better.
It would look like this:
WITH
refined_d AS
(
SELECT
d.id,
d.col1,
d.col2
FROM
d
INNER JOIN
(schema_name).a
ON
( (schema_name).a.ref1 = d.col1)
INNER JOIN
(schema_name).b
ON
( ( schema_name).b.ref2 = d.col2)
)
SELECT
c.col1,
d.col1,
d.col2
FROM
c
JOIN
refined_d d
ON
c.id=d.id;

I want to retrieve users name and there responsibility_key where there end_date is null and i want to convert it to (sysdate+1) using nvl but i am only able to retrieve the responsibility_key not the name please help.
The error in the image says "column ambiguously defined". Take a close look. Your last END_DATE could refer to either the u alias or the table from the subquery. Change it to match the rest of your subquery (FIND_USER_GROUPS_DIRECT.END_DATE)
EDIT
Your query is
select u.USER_NAME, d.responsibility_key from FND_USER u,FND_RESPONSIBILITY_VL d
where responsibility_id in(
select responsibility_id from
FND_USER_RESP_GROUPS_DIRECT WHERE END_USER_RESP_GROUPS_DIRECT.END_DATE=nvl(END_DATE,sysdate+1)) and
u.END_DATE=nvl(END_DATE,SYSDATE + 1)
;
The query isn't formatted, which makes it hard to read.
Not all columns are qualified with table name (or aliases), as mentioned in the comments.
The query currently uses an implicit join.
The query is impossible to understand without seeing the table definitions (desc [table_name]).
For points 1 and 2, a properly formatted query will look something like
select u.user_name, d.responsibility_key
from
fnd_user u,
fnd_responsibility_vl d
where
d.responsibility_id in (
select urgd.responsibility_id
from
fnd_user_resp_groups_direct urgd
where
urgd.end_date = nvl(u.end_date, sysdate+1)
) and
u.end_date = nvl(urgd.end_date, sysdate + 1)
;
This makes it easier to read and in addition to this, you can see that without table definitions I guessed (see point 4) as to which tables the end_date column belongs in your query. If I had to guess, so does Oracle. That means you have an ambiguity problem. To fix it, take a close look at the end_date column as it appears in your original query and where you do not prefix it with anything, you need to prefix it with the appropriate alias (after you have aliased all your tables).
For point 3, you can write your query more clearly with an explicit join and by using aliases for all columns. As for the explicit join I have no idea what your tables look like but one possibility is something like
select u.user_name, d.responsibility_key
from fnd_user u
join fnd_responsibility_vl d
on u.id = d.user_id
where
d.responsibility_id in (
select responsibility_id
from fnd_user_resp_groups_direct urgd
where
urgd.end_date = nvl(u.end_date, sysdate+1)
) and
u.end_date = nvl(urgd.end_date, sysdate+1)
;
If you follow these points you will get to the root of the error.
I want to update a column prtnum and revlvl in table invdtl based on value from select statment, here is the code
update invdtl set invdtl.prtnum = usr_prtmst_xref.prtnum,invdtl.revlvl =
usr_prtmst_xref.colnam ([select
invdtl.prtnum,usr_prtmst_xref.prtnum AS
crossref,invdtl.revlvl,aremst.arecod,aremst.fwiflg from invdtl
join usr_prtmst_xref
on usr_prtmst_xref.prtnum = usr_prtmst_xref.prtnum
join invsub
join invlod
join locmst
join aremst
on aremst.arecod = locmst.arecod
and aremst.wh_id = locmst.wh_id
on locmst.stoloc = invlod.stoloc
and locmst.wh_id = invlod.wh_id
on invlod.lodnum = invsub.lodnum
on invsub.subnum = invdtl.subnum where aremst.arecod = 'EXPR' or
aremst.fwiflg = '1' and rownum <2])
I want to copy two values prtnum and revlvl that are returned by select statement but there is some syntax issue.
There are a bunch of errors here:
The syntax for a multi-column update is basically
update blah
set ( col1, col2 ) = ( select x, y
from
...
)
The syntax for multiple joins is basically
from table1 t1
join table2 t2
on t1.col = t2.col
join table3 t2 on
t2.col = ...
Get ride of "[" and "]"
The predicate rownum<2 is probably to get around the message you received, something like "single row sub-query returns more than 1
row" Which this predicate "fixes" that problem, you are just getting
the first random row; probably not what you want. You probably need to
correlate the sub-query with the update
I would fix these basic syntax errors and try again.
I'm practically new in using oracle and I bumped into a blocker. Below is the query that I created based on what I have researched online to update multiple columns of a table with values from a nested join statement.
UPDATE
(
SELECT
A.COLUMN1 OLD_COLUMN1,
BC.COLUMN1 NEW_COLUMN1,
A.BALANCE OLD_COLUMN2,
BC.COLUMN2_MIN NEW_COLUMN2,
A.COLUMN3 OLD_COLUMN3,
BC.COLUMN3 NEW_COLUMN3
FROM TABLE_A A
INNER JOIN
(
SELECT B.TWWID,
B.ITEMDATE,
B.COLUMN2_MIN,
C.COLUMN3,
C.COUNTRYID,
C.COLUMN1
FROM TABLE_B B
LEFT OUTER JOIN TABLE_C C
ON TO_CHAR(B.ID) = TO_CHAR(C.ID)
) BC
ON A.ID = BC.ID
AND A.DATE = BC.DATE
)ABCUPDATE
SET ABCUPDATE.OLD_COLUMN1 = ABCUPDATE.NEW_COLUMN1,
ABCUPDATE.OLD_COLUMN2 = ABCUPDATE.NEW_COLUMN2,
ABCUPDATE.OLD_COLUMN3 = ABCUPDATE.NEW_COLUMN3;
Selecting the sub-query returns the expected results but when I run the update script as a whole an error is returned.
ORA-01779: cannot modify a column which maps to a non key-preserved
table
Can anyone please explain why I encounter this error and what adjustments can I do to the script to make it work?
Thanks in advance!
I created this query using HQL with Hibernate and Oracle
select c from Cat c
left join c.kittens k
where (c.location= 1 OR c.location = 2)
and (i.activo = 1)
group
by c.id,
c.name,
c.fulldescription,
c.kittens
order by count(e) desc
The problem comes with the fact that in HQL you need to specify all fields in Cat in order to perform a Group By, but fulldescription is a CLOB, and you cannot group by by a CLOB (I get a "Not a Group By Expression" error. I've seen a few solutions around for a pure SQL sentence but none for HQL.
A serious issue GROUP BY of HQL because if you specify your object in GROUP BY and in your SELECT field list behaviours are differents. In GROUP BY has considered only id field but in SELECT field list all fields are considered.
So you can use a subquery with GROUP BY to return only id from your object, so that result becomes an input for the main query, like the follow I write for you.
Pay attention there are some alias table (i and e) not defined, so this query doesn't work, but you know as fixed.
Try this:
select c2 from Cat c2
where c2.id in (
select c.id from Cat c
left join c.kittens k
where (c.location= 1 OR c.location = 2)
and (i.activo = 1) <-- who is i alias??
group by c.id)
order by count(e) desc <-- who is e alias???
am a newbie to Oracle/PL SQL.I've 2 tables A and B.
A has a column CustId,Age,Location and Date. Table B has 2 columns CustId,CustName.
What would be the sql query to show show CustName and Location for a given age?
Thanks.
your question "What would be the sql query to show show CustName and Location for a given age?" helps define your query pretty well:
SELECT CustName, Location
FROM TableA a
INNER JOIN TableB b
ON b.CustId = a.CustId
WHERE a.Age = #
All we need to do on top of that select for your specific fields is make sure to join the two tables on their common column (CustID).
Another option would be to avoid the WHERE statement:
SELECT CustName, Location
FROM TableB b
INNER JOIN TableA a
ON a.CustID = b.CustID
AND a.Age = #
you need join. something like
SELECT custname, location FROM a JOIN b ON a.custid = b.custid WHERE age = [age];
