SQL NESTED Query

i just wanna know whether the JSP can support nested queries such as this:
SELECT     family_name, employee_id
FROM         EMPLOYEE
WHERE     EXISTS
                          (SELECT     *
                            FROM          UserAccess
                            WHERE      UsrGrp = 'ITS/Admin' AND EMPLOYEE.employee_id = UserAccess.EmplID)???

hmm.. i'm using microsoft sql server.. when i execute the above query in the database.. it works.. but when i tried to execute the query using JSP... it prompt me an error.. shown below..

Nested query in FROM clause causes 'SQL Command not properly ended' error

I don't see anything wrong with the above query, it fails with 'SQL Command not properly ended'.
If I remove the usage of the nested query in the FROM clause, then it doesn't give that error. Please advice what I'm doing wrong.

Pls try
SELECT sj.job_id AS job_id, 'STATUS_AWAITING_PREPARATION' AS job_status, sjr.email_sys_attach_filename AS attach_filename, sje.emailaddr as emailaddr_lastsentto
FROM arsnd_jobs sj, (SELECT emailaddr from ARSND_JOB_EMAILS where job_id=sj.job_id AND ROW_NUM=1) SJE, ARSND_JOB_QUEUE sjq,ARSND_JOB_RECIPIENTS sjr
WHERE sj.job_id=sjq.job_id and sj.job_id=sjr.job_id
AND sjq.PROCESSING_STATE=0
ORDER BY sj.created
I have removed the 'as' clause you used for alias of the subquery. It should work fine now.....

Oracle SQL Select query takes long time than expected.

Hi,
I am facing a problem in SQL select query statement. There is a long time taken in select query from the Database.
The query is as follows.
select /*+rule */ f1.id,f1.fdn,p1.attr_name,p1.attr_value from fdnmappingtable f1,parametertable p1 where p1.id = f1.id and ((f1.object_type ='ne_sub_type.780' )) and ( (f1.id in(select id from fdnmappingtable where fdn like '0=#1#/14=#S0058-3#/17=#S0058-3#/18=#1#/780=#5#%')))order by f1.id asc
This query is taking more than 4 seconds to get the results in a system where the DB is running for more than 1 month.
The same query is taking very few milliseconds (50-100ms) in a system where the DB is freshly installed and the data in the tables are same in both the systems.
Kindly advice what is going wrong??

How to do a Nested Query ?

I have three Tables Student, Courses, Marks
Table : Student
Columns
StudentID <PK>
First Name
Last Name
Table : Grades
Columns
StudentID <FK>
Grade
Table : Courses
Columns
StudentID <FK>
CourseID
CourseDesc
Now to get all the course descriptions which this particular student is taking based on the StudentID we do something like this :
SELECT c.courseDesc
FROM Courses c, Student s
WHERE s.StudentID = '100'
AND s.StudentID = c.StudentID
The above will work
But If I need to do it in nested query how can I do it : Something like
SELECT * FROM
SELECT c.courseDesc
FROM Courses c, Student s
AND s.StudentID = c.StudentID
WHERE s.StudentID = '100'
Thanks for the help.
Harsimrat

oops,try this...
SELECT * FROM (
SELECT s.StudentID,c.courseDesc
FROM Courses c, Student s
WHERE s.StudentID = c.StudentID)
WHERE StudentID = '100';
SQL> select * from

Reg: SQL select Query in BPEL process flow


Hi,
I am suppose to execute a SQL select query (in BPEL Process flow) as mention below in JDeveloper using Database adapter.


SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM= <xyz>


AND OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=<xyz> AND SUPP_IND = ‘Y')
Now my question is:
1. What does this "*" refer to in the query and how can I retrieve the value of LENGTH*WIDTH* HEIGHT from the query where LENGTH,WIDTH and HEIGHT are the individual field in the table.
2.What does this " AS" refer to? If " ITEM_CUBE " is the alies for the table name "ITEM" to retrieve the value, then query shoud be evaluated as


SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM_CUBE.ITEM= <xyz>


AND ITEM_CUBE.OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=<xyz> AND SUPP_IND = ‘Y')
Is my assumption correct?
Please suggest asap.
Thanks...




Hi
Thank for your reply!
I have a nested select query which performs on two different table as shown below:

SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM= <abc>


AND OBJECT= (SELECT NAME FROM SUPPLIER WHERE ITEM=<Item> AND SUPP_IND = ‘Y')
I am using DB adapter of Oracle JDeveloper in BPEL process flow, where I can able to select only one master table in DB adapter say SUPPLIER and its attributes at a time.But as per my requirment I need to select both the table (CUBE and SUPPLIER) in a single adapter to execute my query.
It can be achievable by using two DB adapter , One to execute the nested query and another to execute the main qyery considering value of nested query as a parameter.But I want to achieve it by using a single one.
Am I correct with my concept?
Please suggest how to get it ?

Using nested query to avoid repeated object traversal

Hi everyone,
My SQL is still very basic, hopefully this is not a dumb question ;-)
I have a table with a single spatial column of type SDO_GEOMETRY:
SQL> desc WITHIN_POINT_DISTANCE_TAB
Name                                            Null?    Type
POINT                                                    MDSYS.SDO_GEOMETRYin which I store only single point geometries. I discovered that using the min/max SQL operators to get the combined extend of my points is faster than using SDO_TUNE.EXTEND_OF:
SQL> select min(e.point.sdo_point.x) min_x, max(e.point.sdo_point.x) max_x, min(e.point.sdo_point.y) min_y, max(e.point.
sdo_point.y) max_y from WITHIN_POINT_DISTANCE_TAB e;
     MIN_X      MAX_X      MIN_Y      MAX_Y
-44.700001 737.400024 -23.870001 1094.83008
Elapsed: 00:00:00.01but it bothers me a bit to repeat e.point.sdo_point 4 times in the above (what can I say, I'm a developer ;-) So I thought I could use a nested query to select all the SDO_POINT_TYPE sdo_point's and refer it using a p alias, and be able to simplify the query to:
SQL> select min(p.x), min(p.y), max(p.x), max(p.y) from (select t.point.sdo_point from WITHIN_POINT_DISTANCE_TAB t) p;
select min(p.x), min(p.y), max(p.x), max(p.y) from (select t.point.sdo_point from WITHIN_POINT_DISTANCE_TAB t) p
ERROR at line 1:
ORA-00904: "P"."Y": invalid identifierBut obviously this is incorrect, yet I'd like to understand what I'm missing here.
I posited that maybe the sub-query can't return an object member and needs to return a column, but that doesn't appear to be the case:
SQL> select min(p.sdo_point.x), min(p.sdo_point.y), max(p.sdo_point.x), max(p.sdo_point.y) from (select t.point from WIT
HIN_POINT_DISTANCE_TAB t) p;
select min(p.sdo_point.x), min(p.sdo_point.y), max(p.sdo_point.x), max(p.sdo_point.y) from (select t.point from WITHIN_P
OINT_DISTANCE_TAB t) p
ERROR at line 1:
ORA-00904: "P"."SDO_POINT"."Y": invalid identifierCan someone please explain why the nested query approach fails as written above?
More generally, is it a bad idea to go for a nested query just for syntactic reasons? Are there performance implications going the nested query route above? (I actually wanted to see the perf. implications experimentally, but since it fails I can't...)
Any insight would be appreciated. Thanks, --DD

Thank you Peter. I now understand that I need to alias the column in addition to the table (the latter only because I traverse objects which require table aliases).
SQL> select min(t.p.x), min(t.p.y), max(t.p.x), max(t.p.y) from
2 (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt) t;
MIN(T.P.X) MIN(T.P.Y) MAX(T.P.X) MAX(T.P.Y)
-44.700001 -23.870001 737.400024 1094.83008
Elapsed: 00:00:00.01Performance-wise it looks similar, but I need to test on a bigger table because it's too fast with 10K points to show differences. Overall it doesn't look that using the nested query syntax makes the query more readable once all pieces to make it work are there.
Thanks again, --DD
PS: Just aliasing the column and not the outer table fails:
SQL> select min(p.x), min(p.y), max(p.x), max(p.y) from (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt);
select min(p.x), min(p.y), max(p.x), max(p.y) from (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt)
ERROR at line 1:
ORA-00904: "P"."Y": invalid identifier

Count(*) with nested query

Hi,
I have a question about the count(*) with nested query.
I have a table T1 with these columns:
C1 number
C2 number
C3 number
C4 number
C5 number
(The type of each column is not relevant for the example.)
This query:
select C1, C2, C3, C4
from T1
group by C1, C2
it's not correct becausa C3 and C4 are not columns specified in the GROUP BY expression.
If if run this query:
select count(*)
from (select C1, C2, C3, C4
from T1
group by C1, C2)
I haven't an error message (the result is correctly the number of records).
Why?
Thanks.
Best regards,
Luca

Because you are just selecting count(*) and none of the columns from the subquery, Oracle is optimising it by ignoring the selected columns and just running the sub query with the group by columns. I know it seems odd, but if you take a basic example:
SQL> ed
Wrote file afiedt.buf
1 select count(*)
2 from (select empno, sal, mgr, deptno
3 from emp
4* group by deptno)
SQL> /
COUNT(*)
3... all columns but deptno are ignored
... but if you include one of the other columns, even if you group by that column...
SQL> ed
Wrote file afiedt.buf
1 select count(*), empno
2 from (select empno, sal, mgr, deptno
3 from emp
4 group by deptno)
5* group by empno
SQL> /
group by empno
ERROR at line 5:
ORA-00979: not a GROUP BY expression
SQL>... the error returns, because you're forcing oracle to include the column in the subquery.

left outer join
EXISTS (SELECT 1 FROM IvItemGenericLink G

Executing nested query contains ORDER BY:Help Needed

I have a database in ORACLE 8.0 enterprise
edition in HP-UX. I am trying to execute the following query
"select * from ( select * from temptable order by value desc) where rownum < 5"
and I am getting the following error
"missing right parenthesis"
This syntax is given in the Oracle user guide
under sql commands section and it is not
working.
Similar query is working on Oracle 8.1 running on Win NT.
Does any body throw some light.
Thanks in advance
-raj

Your query works fine in Oracle 8i:
SELECT *
FROM (SELECT *
FROM temptable
ORDER BY value DESC)
WHERE ROWNUM < 5;
However, prior to Oracle 8i, in Oracle 8.0, it is not allowed to have an ORDER BY clause within a nested query. So, in Oracle 8.0, a query like the above cannot work. However, the following, with the ORDER BY clause in the outer query will work:
SELECT *
FROM temptable a
WHERE 5 >=
(SELECT COUNT (*) + 1
FROM temptable b
WHERE b.value > a.value)
ORDER BY a.value DESC;
null

Sql select query problem

hi friends,
i've a view called "risk_efforts" with fields user_id,user_name,wknd_dt,week_day,prod_efforts,unprod_efforts.

USER_ID VARCHAR2(14)
USER_NAME VARCHAR2(50)
WKND_DT VARCHAR2(8)

PROD_EFFORTS NUMBER
UNPROD_EFFORTS NUMBER
data is like this:
when there is some data in prod_efforts, unprod_efforts will be null
when there is some data in unprod_efforts, prod_efforts will be null
for example:
USER_ID     USER_NAME     WKND_DT     WEEK_DAY     PROD_EFFORTS     UNPROD_EFFORTS

G666999     GTest     20100403     TUE     14     null
now i want to combine these 2 rows into 1 row i.e o/p should be like this
USER_ID     USER_NAME     WKND_DT     WEEK_DAY     PROD_EFFORTS     UNPROD_EFFORTS
G666999     GTest     20100403     TUE     14 3
i've tried all combinations but couldn't get the query. Please help me with the exact SQL select query.
thanks,

Welcome to the forum.
First read this:
Urgency in online postings
Secondly, it's always helpful to provide the following:
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details.
You have provided #3 and #4. However with no usable form of sample data forum members will often not respond as quickly as they could if you provided #2.
I'm just wagering a guess here but what about this:SELECT ROW_ID
, USER_ID
, WKND_DT
, WEEK_DAY
, MAX(PROD_EFFORTS) AS PROD_EFFORTS
, MAX(UNPROD_EFFORTS) AS UNPROD_EFFORTS
FROM RISK_EFFORTS
GROUP BY ROW_ID
, USER_ID
, WKND_DT
, WEEK_DAY

How to capture all the rows returned from a sql select query in CPO

Hi,
I am executing an sql select query which returns multiple rows. I need to capture the values of each row to specific variables. How do I proceed.
Thanks,
Swati

The select activities ("Select from Oracle," Select from SQL Server," etc.) against database already return tables. Use one of the database adapters to do your select, and it will already be in a table form. Just put your query in the select and identify the columns in your result table. The online help or the database adapter guides in the product documentation can help.

From SharePoint Content Database, Using SQL-Server Query how to fetch the 'Document GUID' based on 'Content Type'

I want to get all the documents based on content type using SQL Server Query. I know that, querying the content database without using API is not advisable, but still i want to perform this action through SQL Server Query. Can someone assist ?

You're right, it's not advisable, may result in corruption of your databases and might impact performance and stability. But assuming you're happy to do that then it is possible.
Before you go down that route, have you considered using something more safe like PowerShell? I've seen a script exactly like the one you describe and it would take far less time to do it through PS than it would through SQL.

Sql server query

sql server query to rearrange the rows after inserting the rows in a table

You want to re-arrange the data physically?!!! Why? I believe its something impossible other than having a clustered key(there could be some strange ways of doing it) and a thing that should not worry about. Always there is a ORDER BY CLAUSE to order your
data while retrieving

Sql developer query window corrupting on scroll

Hi there
I have a weird error - when I scroll in my SQL developer query window (tab) the text corrupts and only comes back if I click in the window somewhere or save. Has anyone else seen this? I'm on version 1.5.5 and don't really want to upgrade to the latest as I don't like the new layout (no dbmsoutput etc in the results window)
Cheers, Kate

sorted it by adding a line AddVMOption -Dsun.java2d.noddraw=true to the sqldeveloper.conf file, as per thread SQL Editor not refreshing after scroll on Windows Vista
