How to write a query on a component-item-type properties

hi
For the following sample repository definition file.
<item descriptor name ="student" idcolumn="id">
<property name="name" data-type="string"/>
<property name="department" component-item-type="department" data-type="list" />
</item descriptor>
<item descriptor name ="department">
<property name="name" type="string"/>
<property name="HOD" data-type="string" />
</item descriptor>
If I get a view of the student Itemdescriptor and will I be able to query on the department item descriptor in the same rql ?

Nitin,
Thanks for the mail.
I am getting below error.
Attempt to create a sub-property query expression for the property: "department", which is not a RepositoryItem. Only properties that are RepositoryItems can have sub-properties.*
atg.repository.RepositoryException: Attempt to create a sub-property query expression for the property: "department", which is not a RepositoryItem. Only properties that are RepositoryItems can have sub-properties
For more clarity PFB how the ItemDescriptor looks like
<item-descriptor name="student" display-property="displayName">
<property name="isActive" data-type="boolean" default="false"/>
<table name="student" type="auxiliary" id-column-names="student_ID">
<property name="studentId" display-name="student" column-name="student_id" data-type="string" required="true"/>
</table>
<table name="student_department" type="multi" id-column-name="student_ID" multi-column-name="sequence_id">
<property name="department" display-name="department" column-name="department_id" data-type="list" component-item-type="departmentl" />
</table>
</item-descriptor>
<item-descriptor name="department" super-type="superDepartment" sub-type-value="department" display-property="name" display-name="departmentname">
<table name="department" type="auxiliary" id-column-name="department_id">
<property category="Basics" name="location" data-type="int" column-name="location" display-name="Location" required="true" default="1">
<attribute name="propertySortPriority" value="-5"/>
</property>
<property category="Basics" name="name" display-name="name" column-name="name" data-type="String" />
<property category="Basics" name="HOD" display-name="HOD" column-name="HOD" data-type="String"/>
</table>
</item-descriptor>
Thanks

How to write this query to filter combination of few values

Hi,
I have a table CHIMM which is a transaction table and contains information of the vaccines given to a child.
columns are: child_id, vacc_id, vacc_given_dt. I have to query for remaining vaccines.
HEXA is a vaccine_id which is composite vaccine of DPT1,POL1,HBV1 & HIB1 (vaccine ids).
I want to write to query if any of DPT1,POL1,HBV1 & HIB1 given then HEXA should not be displayed in the result.
OR
if HEXA is given then of course any of DPT1,POL1,HBV1 & HIB1 should not be displayed in the result.
How to write this query?
Regards

Hi,
I'm still not sure what the output you want from that sample data is. Do you just want the child_ids, like this
CHILD_ID
       3
       4? If so, here's one way to get them:
WITH     all_vacc_ids     AS
     SELECT     c.child_id
     ,     c.vacc_id          AS child_vacc_id
     ,     v.vacc_id
     ,     COUNT ( CASE
                         WHEN c.vacc_id = 'HEXA'
                   THEN 1
                     END
                )       OVER ( PARTITION BY c.child_id
                                   )    AS hexa_itself
     FROM          vacc   v
     LEFT OUTER JOIN     chimm c     PARTITION BY (c.child_id)
                      ON     c.vacc_id     = v.vacc_id
     WHERE   v.vacc_desc       = 'HEXA'     -- See note below
SELECT       child_id
FROM       all_vacc_ids
WHERE       child_vacc_id     IS NULL
AND       vacc_id     != 'HEXA'
AND       hexa_itself     = 0
GROUP BY child_id
rha2 wrote:there are alot of vaccines, i just put 3 for example. this query gives error: invalid relational operatorAre you saying that the vacc table contains other rows, but those other rows are not needed for this problem? It would be good if you included an example in the sample data. The query above considers only the rows in vacc where vacc_desc='HEXA'. You can have other rows in the vacc table, but they won't affect the output of this query. The query above makes no assumptions about the number of rows that have vacc_desc='HEXA'; it will report all child_ids who are missing any of them, regardless of the number (assuming the child does not have the 'HEXA' vacc_id itself, like child_id=1).
You still haven't said which version of Oracle you're using. The query above will work in Oracle 10 (and higher).

How to write this query ?

how to write this query ?
list the emp name who is working for the highest avg sal department.
I can use row_number over to get correct result. If we don't use this row_number function, just plain sql, how to do it ?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno

I can use row_number over to get correct result. If we don't use this row_number function, just plain sql, how to do it ?ROW_NUMBER is just plain SQL, and has been since Oracle 8.1.
ROW_NUMBER (or its close relative, RANK) is the simplest and most efficient way to solve this problem. Why not do this the right way?
the row_number version is like this
select emp.* from emp ,
select deptno, row_number() over (order by avg(sal) desc) r from emp
group by deptno
)e
where e.r = 1
and emp.deptno = e.deptno
If there happens to be a tie (that is, two or more departments have the same average sal, and it is the highest), then the query above will only arbitrarily treat one of them (no telling which one) as the highest. Change ROW_NUMBER to RANK to get all departments with a claim to having the highest average sal.
You could use the ROWNUM pseudo-column instead of ROW_NUMBER, if all you want to do is avoid ROW_NUMBER.
Without using ROW_NUMBER or RANK, there are lots of ways involving other analytic functions, such as AVG and MAX.
If you really, really don't want to use analytic functions at all, you can do this:
SELECT     *
FROM     scott.emp
WHERE     deptno     IN (
                  SELECT       deptno
                  FROM       scott.emp
                  GROUP BY deptno
                  HAVING       AVG (sal) = (
                                                   SELECT    MAX (AVG (sal))
                                           FROM          scott.emp
                                           GROUP BY deptno

How to write sql query for counting pairs from below table??

Below is my SQL table structure.
user_id | Name | join_side | left_leg | right_leg | Parent_id
100001 Tinku Left 100002 100003 0
100002 Harish Left 100004 100005 100001
100003 Gorav Right 100006 100007 100001
100004 Prince Left 100008 NULL 100002
100005 Ajay Right NULL NULL 100002
100006 Simran Left NULL NULL 100003
100007 Raman Right NULL NULL 100003
100008 Vijay Left NULL NULL 100004
It is a binary table structure.. Every user has to add two per id under him, one is left_leg and second is right_leg... Parent_id is under which user current user is added.. Hope you will be understand..
I have to write sql query for counting pairs under id "100001". i know there will be important role of parent_id for counting pairs. * what is pair( suppose if any user contains both left_leg and right_leg id, then it is called pair.)
I know there are three pairs under id "100001" :-
1. 100002 and 100003
2. 100004 and 100005
3. 100006 and 100007
100008 will not be counted as pair because it does not have right leg..
But i dont know how to write sql query for this... Any help will be appreciated... This is my college project... And tommorow is the last date of submission.... Hope anyone will help me...
Suppose i have to count pair for id '100002'. Then there is only one pair under id '100002'. i.e 100004 and 100005

Sounds like this to me
DECLARE @ID int
SET @ID = 100001--your passed value
SELECT left_leg,right_leg
FROM table
WHERE (user_id = @ID
OR parent_id = @ID)
AND left_leg IS NOT NULL
AND right_leg IS NOT NULL

Hi All
Pls advise how to write a query whereas the return result is the

I know there is describe <table_name>;
Is there any other ways?
Pls advise

Edited by: user600866 on Oct 14, 2008 12:13 AM

Data Dictionary table user_tab_columns has all the column names. You can query that and get what ever you want.
To get the column list of a table just query
select *
from user_tab_columns
where table_name = <your_table>Edited by: Karthick_Arp on Oct 14, 2008 12:18 AM

How to write named query if we want to use IN syntax in our sql statement?

I cannot find a suitable category about named query, so please move to appropriate place if there is any.
When we write named query, below statement is fine.
Query q2 = em.createQuery("SELECT o FROM Table1 as o WHERE field1 = :input1");             q2.setParameter("input1", "value1");
Now, my question is, how can I write this type of query when we want to use the IN sql syntax? As below statement CANNOT return correct results. Even I tried to put a pair of single quote [ ':input2' ], it won't help also.
Query q2 = em.createQuery("SELECT o FROM Table1 as o WHERE field2 IN (:input2)");             q2.setParameter("input1", "3633, 3644");
Can anyone suggest? Thanks.

Can anyone suggest?The above is in your code right? Not in some configuration file?
Then you do it the same way as with regular jdbc/sql.
1. You start with a collection of values - call it collection A.
1. Create a for loop that dynamically creates the string using 'bind' variables (whatever you want to call the 'colon' entity in the above).
2. Call the createQuery method using the string that was created
3. Create a second loop that iterates over A and populates with setParameter.
Pseudo code
        Object[] A = ...
        String sql = "SELECT o FROM Table1 as o WHERE field2 IN (";
        for (int i=1; i <= A.length; i++)
              if (i == 1)
                 sql += ":input" + i;
             else
                 sql += ",:input" + i;
        sql += ")";
        Query q2 = em.createQuery(sql);
        for (int i=1; i <= A.length; i++
              q2.setParameter("input" + i, A[i-1]);
              }By the way there is a jdbc forum.

How to write select query for this

Hi,
I had a html form and in the for i had drop down box and it needs to select multiple values from the drop down box. When i select multiple values then i have to write the SQL select statement query .
When i try to write the select statement and trying to run i am getting error.
select * from Table
where emo_no = '1,2,3'
this is how i write query please suggest me how to write query for selecting multiple values from the drop down box.
Thanks

select * from Table
where emo_no in ( 1,2,3)
for integer values
select * from Table
where emo_no in ('1','2','3')
for characters
If we talk about large scale applications that may have millions of records, I would suggest this.
declare @t table (v int)
insert into t (v) values (1)
insert into t (v) valves (2)
insert into t (v) values (3)
select *
from table
inner join @t t on table.emo_no = t.v
Using "in" for a where clause is not so bad for filtering on a few values, but if you are filtering a lot of rows and a lot of values (emo_no) the performance degrades quickly for some reasons beyond the scope of this.
This is just one solution, I'll through this out as well, instead of an in memory (@t) table, doing a disk based temp table (#t) and creating an index on the column "v".
create table #t (v int)
insert into #t (v) values (1)
insert into #t (v) valves (2)
insert into #t (v) values (3)
create index ix_t on #t (v)
select *
from table
inner join #t t on table.emo_no = t.v
drop table #t
Pardon any syntax errors and careful using a drop statement.
Sometimes in memory tables work better than disk temp tables, it takes some testing and trial and error depending on your datasets to determine the best solution.
Probably too much info ;-)
