SQL-display two rows in a table as one row in the select query
Hi guys
Sorry if this sounds a little odd.
I have two tables
Im sorry but i tried to format these tables in text to make them look like tables but this text processor deletes space based formatting.
States
state id | Name
1 | california
2 | New york
3 | New hampshire
.......so on
Grades
Gradeid | State id | Language | Avgscore |
1 | 1 | ENG | 67 |
2 | 1 | FRENCH | 76 |
2 | 2 | SPANISH | 34 |
Now i wanna write an sql query thats gonna display like
State Name | State id | English | French | SPANISH|
California | 1 | 67 | 76 | null
New York | 2 | null | null | 34
I know how to get just an sql query where i can say
SELECT A.id, A.Name, G.Language,G.Avgscore
FROM States A , Grades G
where A.state_id = G.state_id
and G.Language = 'English'
How do i accomplish this?
Thanks

Regarding:

before and after your example, so formatting will be maintained when posting your example.
Example, when you type:
{noformat}select * from dual;
{noformat}
it will appear as:select * from dual;
when you post it on the forum.

Convert multiple rows in a table into one row based on the primary key
I have 2 tables
CREATE TABLE Files (FileID int, fileName varchar(20))
insert into Files values (1,'F1')
insert into Files values (2,'F2')
insert into Files values (3,'F3')
CREATE TABLE Versions (FileID int, VersionNum varchar(10))
insert into Versions values (1, 'V1')
insert into Versions values (1, 'V2')
insert into Versions values (1, 'V3')
insert into Versions values (2, 'V1')
The two tables join using FileID. I want a listing of the fileName and the all corresponding versions on one line. There may not be a version for a file or there may be multiple versions for the file. The output I want is
F1, V1, v2, v3
F2, V1
F3
Any help would be appreciated.
lggardner,
If you want them as different columns, you can PIVOT. However, this requires to know the max numebr of versions that may be there (here I have done with 3). If you dont have that info, then you might have to resort to dynamic SQL..
;with cte
as
select f.fileid,f.fileName,ISNULL(v.VersionNum,'') as VersionNum,row_number() over(partition by f.fileid order by f.filename,v.versionnum) rownum from #files f
left join #versions v
on f.fileid=v.fileid
select fileid,fileName,ISNULL([1],'') as [1],ISNULL([2],'') as [2],ISNULL([3],'') as [3]
from
select * from cte
) tab
PIVOT
Max(VersionNum) for rownum in ([1],[2],[3])
) pvt

Using case when statement in the select query to create physical table
Hello,
I have a requirement where in I have to execute a case when statement with a session variable while creating a physical table using a select query. let me explain with an example.
I have a physical table based on a select table with one column.
SELECT 'VALUEOF(NQ_SESSION.NAME_PARAMETER)' AS NAME_PARAMETER FROM DUAL. Let me call this table as the NAME_PARAMETER table.
I also have a customer table.
In my dashboard that has two pages, Page 1 contains a table with the customer table with column navigation to my second dashboard page.
In my second dashboard page I created a dashboard report based on NAME_PARAMETER table and a prompt based on customer table that sets the NAME_ PARAMETER request variable.
EXECUTION
When i click on a particular customer, the prompt sets the variable NAME_PARAMETER and the NAME_PARAMETER table shows the appropriate customer.
everything works as expected. YE!!
Now i created another table called NAME_PARAMETER1 with a little modification to the earlier table. the query is as follows.
SELECT CASE WHEN 'VALUEOF(NQ_SESSION.NAME_PARAMETER)'='Customer 1' THEN 'TEST_MART1' ELSE TEST_MART2' END AS NAME_PARAMETER
FROM DUAL
Now I pull in this table into the second dashboard page along with the NAME_PARAMETER table report.
surprisingly, NAME_PARAMETER table report executes as is, but the other report based on the NAME_PARAMETER1 table fails with the following error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 16001] ODBC error state: S1000 code: 1756 message: [Oracle][ODBC][Ora]ORA-01756: quoted string not properly terminated. [nQSError: 16014] SQL statement preparation failed. (HY000)
SQL Issued: SET VARIABLE NAME_PARAMETER='Novartis';SELECT NAME_PARAMETER.NAME_PARAMETER saw_0 FROM POC_ONE_DOT_TWO ORDER BY saw_0
If anyone has any explanation to this error and how we can achieve the same, please help.
Thanks.Hello,
Updates :) sorry.. the error was a stupid one.. I resolved and I got stuck at my next step.
I am creating a physical table using a select query. But I am trying to obtain the name of the table dynamically.
Here is what I am trying to do. the select query of the physical table is as follows.
SELECT CUSTOMER_ID AS CUSTOMER_ID, CUSTOMER_NAME AS CUSTOMER_NAME FROM 'VALUEOF(NQ_SESSION.SCHEMA_NAME)'.CUSTOMER.
The idea behind this is to obtain the data from the same table from different schemas dynamically based on what a session variable. Please let me know if there is a way to achieve this, if not please let me know if this can be achieved in any other method in OBIEE.
Thanks. -
ORA-01427: single-row subquery returns more than one row -- no solution
Hello to all:
I have to tables:
Table a anwender (Email,Dept). --> all fields are filled
Table b dingo (Name,email,dept) --> all fields are filled
I now want to update the table a with the data from table b:
update anwender a set a.abteilung = ( select distinct b.abteilung from dingo b where b.email = a.email);
Then I got the error: ORA-01427: single-row subquery returns more than one row
Every dept is about 100x in the database, so it is clear that i got more than one row back. But how can I update the table now?Okay, I got several duplicates, and I deletet a lot of data in my database.
Now I want to remove all entries with more than one departments per mail adresses.
a
select email,count(abteilung) from dingo group by email having count(abteilung)>1 order by count(abteilung)
shows me all the fake mailadresses.
But a
delete from dingo where email in (select email,count(abteilung) from dingo group by email having count(abteilung)>1 order by count(abteilung) );
gives me a
SQL Error: ORA-00907: missing right parenthesis
I´m very confused now ...
Oops, now I got the solution:
delete from dingo where email in (select email from (select email,count(abteilung) from dingo group by email having count(abteilung)>1 )) ;

Update gives "single-row subquery returns more than one row"
Hi,
I have to update a table by getting values from two other tables. While doing that the inner query returns more than one value. I am not sure how to implement the logic without returning more than one row in sub quesry. Need help on that.
My query:
update buf_office_str o
set o.manager_ident =
(select sp.ident
from se2_r_src_sourceperson sp ,
(select distinct director_name, team_name from buf_sales_dump )t
where SP.SRCNAME = upper(substr(t.director_name,instr(t.director_name,' ')+1,length(t.director_name))||', '||substr(t.director_name,1,instr(t.director_name,' ')-1 ) )
and o.office_descr = t.team_name
Basically the query gets teh manager id from sp table where sp.srcname = t.team-name.
The office descr should be equal to the team_name.
This is the logic I am working towards:
For each office, i get the office_descr and get corresponding team_name. Match the team's director_name (from table t) with the sp.name and return the employee's id (sp.ident) for that office_descr.
I need to update all 50 offices with corresponding managerid for that office in buf_office_str table.
Is it possible to get done in one update? Pls let me know.Hi,
"Single-row subquery returns more than one row" is one of those error messages that actually means what it says: the correlated sub-query in your SET clause is sometimes returning 2 or more rows .
The solution could be as simple as making the sub-query SELECT DISTINCT , as its in-line view, t, already is.
It's possible you have bad data, or a mistake in your statement.
To find the problem cases, you can run something like this:
WITH sub_q AS
SELECT -- DISTINCT ?
sp.ident
, t.team_name
, COUNT (*) OVER (PARTITION BY t.team_name) AS cnt
FROM se2_r_src_sourceperson sp
, ( SELECT DISTINCT director_name
, team_name
FROM buf_sales_dump
) t
WHERE sp.srcname = UPPER ( SUBSTR ( t.director_name
, INSTR ( t.director_name
) + 1
, LENGTH (t.director_name)
|| ', '
|| SUBSTR ( t.director_name
, 1
, INSTR ( t.director_name
) - 1
SELECT o.* -- or whatever helps you
, sq.*
FROM buf_office_str o
JOIN sub_q sq ON o.office_descr = sq.team_name
WHERE sq.cnt > 1
;If you'd like more help, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables as they exist before the UPDATE, and the results you want from that data (that is, the contents of buf_office_str after the UPDATE). Make sure the problem occurs with the sample data you post. -
Automated row fetch returns more than one row
Greetings All,
Does anyone know of a way to call a page if the automated row fetch returns more than one row. I have a form with a primary and secondary key. If I search only on the primary key and there is more than one row I would like to call a popup with the multiple list, is this possible?
Regards
MarkCreate a view on a table you want to update if you have more than two key values.
However, the automated row fetch does support two key values.

blart EQ 'DP' )
AND PRCTR IN R_PC.
Thanks in advance
Regards
chetanHi Chetan ,
I will suggest you two things :
1. Try to add Secondary ( Non-unique) index on table BSAD with fields : mandt,bukrs,kunnr,budat,xblnr,blart,prctr.
but before adding this index test the selectivity of this index by going to Tcode DB05
2. In the select query you have used OR condition for blart. Instead of this try to create a ranges table for blart and append the values 'DA','DZ','ZP','KZ','DP' and use this in the select query. This will improve the performance for sure.
Hope this will help to ypu.

In this 2nd suquery fails some of the order_numbers returning more than price_list based on dates and in that situvation also my query has to successfullRemember, none of the people who want to help you are as familiar with your application as you are, so you have to explain things that are obvious to you.
What does "sucessful" mean in this case? Does is mean producing the right results? What are the right results? How can you tell them apart from the wrong results?
As the errror message says, the (immediate) problem is that a single-row sub-query is returning more than a single row. If the sub-query tries to bring back more than 1 row, which one do you want to use? Or do you want to use some kind of aggregate, such as the average, which might not be the same as any of them?
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Simplify the problem as much as possible. For example, remove all columns and tables that have nothing to do with the part you don't know how to do.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

set col1 = (select distinct col2 from table B) it gives me the error ORA-01427: single-row subquery returns more than one row
When I try the query:
update (select x.col1 x_col1,y.col2 y_col2
from (select id,col1,row_number() over (partition by id order by null /*col1*/) rn
from table_a
) x,
(select id,col2,row_number() over (partition by id order by col2) rn
from table_b
) y
where x.id = y.id
and x.rn = y.rn
set x_col1 = y_col2
it gives me an error saying ora-01779 :cannot modify a column which maps to a non key- preserved table. It shows the same even when I add the key to the tables.
My Database version is Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Kindly help.Another way, not waterproof too relay on rowid, but in your case it could work.
You have to verify it by yourself
update test_a aa
set col1 =
(select b.col1 from
(select
id, col1
,row_number() over
(partition by id order by col1) rn
from table_b) b,
( select
rowid, id, col1
,row_number() over (partition by id order by col1) sort_order
from test_a
) a
where
a.id=b.id
and
sort_order = rn
and
aa.rowid=a.rowid

ORA-01427: single-row subquery returns more than one rowHi,
Welcome to the forum!
Whenever you have a question, please post some sample data, so that people can re-create the problem and test their solutions.
CREATE TABLE and INSERT statements, like the ones below, are great:
CREATE TABLE baemployee
( employee NUMBER (4)
, stock_nbr VARCHAR2 (10)
INSERT INTO baemployee (employee, stock_nbr) VALUES (1234, 'FUBAR');
CREATE TABLE employee
( employee NUMBER (4)
, emp_status VARCHAR2 (10)
INSERT INTO employee (employee, emp_status) VALUES (1234, 'ACTIVE');CREATE TABLE AS is good, too:
CREATE TABLE emp_check_dig
AS SELECT 1234 AS employee, 'AA1234567890ZZZ' AS check_digit FROM dual
UNION ALL SELECT 1234, 'AA2121212121ZZZ' FROM dual
;Also post the results you want from that data. In this case, the results would be the contents of the baemployee table after you run the UPDATE.
Would you want:
employee stock_nbr
1234 1234567890or would you want
employee stock_nbr
1234 2121212121If you run the UPDATE statement you posted with the data above, you'll get the "ORA-01427: single-row subquery returns more than one row" error, and you can see what causes it: there is more than one row from emp_check_dig that could be used to UPDATE the same row of baemployee. Say what you want to do in this situation (and why), and someone will help you find a way to do it. -
