I have two table which I want to select Name from t2.
The situation is following.
I have t1 Policy which containt EmployeeID
And table t2 which containt Name
Now I want to select which Employee release policy.
So in t1(Policy- AUTO.POL) I have column: SIFRA_RAD
and t2(Employee-AUTO.SIFRAD) I have colum: SIFRA_R, Ime
I try something like this:
select auto.pol.sifra_rad, auto.sifrad.ime
from auto.sifrad
inner join auto.pol on auto.sifrad.ime = auto.pol.sifra_rad;
After that I get error
ORA-00933: SQL command not properly ended
I have no idea what is wrong here. Any suggestion?
The problem comes from query, and we fix it
select p.sifra_rad, s.ime from auto.sifrad s, auto.pol p where s.ime = p.sifra_rad

I have this two tables
If I use the lookup step using the EMPLOYEEID and YEAR I get this columns:
But I need to get this instead:
I have prepare a solution Here.
Using this you will get your result.
Please let me know if its ok with you.
A lookup is designed to retrieve fields from a matching record in another table and append them to the "master" record.
If you want to combine records from 2 tables into a single dataset then you need to UNION them together.
Update following comment
Something like this pseudo-code ought to work:
SELECT T1.*
FROM TABLE1 T1
UNION
SELECT T2.*
FROM TABLE1 T2
INNER JOIN TABLE1 T1A ON T2.KEY1 = T1A.KEY1 AND T2.KEY2 = T1A.KEY2 AND ...
This is my query, if i run the error is : Error in query: ORA-00907: missing right parenthesis, anybody can solve my problem?
Create table r_tcash_loci_act_tmp AS (
SELECT DISTINCT
R_TCASH_LOCI_ACT.MSISDN AS MSISDN_LOCI,
R_TCASH_ACT_MSISDN.MSISDN AS MSISDN_ACT,
R_TCASH_LOCI_ACT.AREA,
R_TCASH_LOCI_ACT.REGIONAL,
R_TCASH_LOCI_ACT.BRANCH,
R_TCASH_LOCI_ACT.SUB_BRANCH,
R_TCASH_LOCI_ACT.CLUSTERX,
R_TCASH_LOCI_ACT.UPDATED,
R_TCASH_ACT_MSISDN.DAILY,
R_TCASH_ACT_MSISDN.TOTAL_TRX,
R_TCASH_ACT_MSISDN.TOTAL_VOL
FROM R_TCASH_ACT_MSISDN
INNER JOIN R_TCASH_LOCI_ACT
ON R_TCASH_LOCI_ACT.MSISDN = R_TCASH_ACT_MSISDN.MSISDN
GROUP BY R_TCASH_LOCI_ACT.MSISDN AS MSISDN_LOCI
HAVING COUNT(R_TCASH_LOCI_ACT.MSISDN ) > 10);
It's a simple syntax error. You included the column alias in the GROUP BYclause (probably a cut'n'paste error).
GROUP BY R_TCASH_LOCI_ACT.MSISDN AS MSISDN_LOCI
So just remove the AS MSISDN_LOCI.
Although given that you have a DISTINCT clause and no aggregated columns it's a mystery why you have the GROUP BY at all. You should remove the whole line.
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 have a created a table (movies) in Hive as below(id,name,year,rating,views)
1,The Nightmare Before Christmas,1993,3.9,4568
2,The Mummy,1932,3.5,4388
3,Orphans of the Storm,1921,3.2,9062
4,The Object of Beauty,1991,2.8,6150
5,Night Tide,1963,2.8,5126
6,One Magic Christmas,1985,3.8,5333
7,Muriel's Wedding,1994,3.5,6323
8,Mother's Boys,1994,3.4,5733
9,Nosferatu: Original Version,1929,3.5,5651
10,Nick of Time,1995,3.4,5333
I want to write a hive query to get the name of the movie with highest views.
select name,max(views) from movies;
but it gives me an error
FAILED: Error in semantic analysis: Line 1:7 Expression not in GROUP BY key name
but doing a group by with name gives me the complete list (which is expected).
What changes should I make to my query?
It is very possible that there is a simpler way to do this.
select name
from(
select max(views) as views
, name
, row_number() over (order by max(views) desc) as row_num
from movies
group by name
) m
where row_num = 1
After little bit of digging, I found out that the answer is not so straightforward as we do in SQL. Below query gives the expected result.
select a.name,a.views from movies a left semi join(select max(views) views from movies)b on (a.views=b.views);
I do know update clause doesn't work with joins in Oracle.
update table1 Pr
set code = (select t2.class_attr_value from table2 t2
where class_attr_name = 'sample' and Pr.epcclass_id = t2.epcclass_id)
I would be thankful if someone can help me modify my query so that I don't get the error of SQL Command not ended properly.
Your Query seems okay to me I just added Table Alias. Your query will update all records in table1. What error you are getting...??
Suggestions,
a) Unless it's the intent that you want to update all records, add a where clause in the query to avoid updating all records...
b) If you are getting (ORA-01427: single-row subquery returns more than one row) then means corelated sub query (within brackets) is missing some condition to make it fetch only 1 row per epcclass_id.
update table1 Pr
set Pr.code = (select t2.class_attr_value
from table2 t2
where t2.class_attr_name = 'sample'
and t2.epclass_id = Pr.epcclass_id
);
Try this:
UPDATE table1 Pr INNER JOIN table2 t2
ON t2.class_attr_name = 'sample' AND Pr.epcclass_id = t2.epcclass_id
SET Pr.code = t2.class_attr_value
