Query Bean Where clause

In Query Bean (Auto Customization Criteria) , OA FWK generate
where clause automatically .
I want to disable this criteria in some cases. Is there any way exists?
(Disable means remove some condition )
I want to see runtime query with where clause(In case of Query Bean) . Is there is any way to find out it?
Thanks, Avaneesh

You have couple of options to do this,
1. You can use getCriteria API on the queryBean which will stop the query execution by framework and it's the responsibility of the developer to use the dictionary returned by getCriteria and bind the complete where clause yourself.
2. You can use getNonViewAttrCriteria API on queryBean. This provides a dictionary of criteria on the column which are not mapped to a viewAttribute, for example if you want a poplist in the search region which has values like "Last one week", "Last 2 weeks", "Last 15 days" and so on and want to bind the criteria your self by interpreting the value selected.
In this case, framework still binds the where clause for the other criteria's which are mapped to a vo based column in the table and expects the developer to bind the criteria for these non viewattribute mappings in the controller.
I think your requirement fits in the second approach.

Query using where clause

I am not able to run a SQL query using where clause.
the query is as follows:
I extract the text input by the user in a text field say 'a' and
store it in string 'y'.
String y= a.getText();
//running the query
Select A from B where B.x=y;
how do we run a where clause when y is a string variable instead of value?

Use the following :
String y = a.getText();
String query ="select A.CODE from Port A where A.NAME=" + "'" + y + "'" ;
ResultSet rs= stmt.executeQuery(query);

Hierarchical query with where clause

Hi,
How can I query hierarchically a query with WHERE clause? I have a table with three fields session_id,id and root_id.
When I try with the following query,
select id, level from relation
where session_id = 79977
connect by prior id = root_id start with id = 5042;
It gets duplicate values.
I want the query to show in the hierarchical manner with a filter condition using WHERE clause. Please help me how can I achieve this. If you know any link that describes more about this, please send it.
Thanks in Advance.

-Parmy

Hi Sridhar Murthy an others,
Thanks a lot for your/the answer. It's working for me. It saved a lot of other work around without the proper knowledge of hierarchical query. Please send me any link that describes these issues in detail and also I hope as I have mentioned in the other message, same cannot be achieved on views or ( on two different tables ???)
Any way thanks for your reply,
It's working for me.

Dynamic query in where clause while looping in an internal table.

Hi,
Had a small question : How can i make a dynamic query for the WHERE clause while looping at an internal table.
i want to implement a dynamic where clause query for the below example.
it_cfx_col is an internal table and wa_cfx_col is a work area for it_cfx_col
DATA :
i_cfx_col TYPE TABLE OF cfx_col,
wa_cfx_col LIKE LINE OF i_cfx_col.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
LOOP AT it_cfx_col INTO wa_cfx_col
WHERE CREATED_BY = l_name
AND SCENARIO = l_scenario.
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
Now i want to write a dynamic query for the where clause.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
l_where_clause = 'CREATED_BY = l_name'.
l_where_clause2 = 'AND SCENARIO = l_scenario'.
if l_scenario is not initial.
CONCATENATE l_where_clause l_where_clause2
INTO l_where_clause SEPARATED BY space.
endif.
LOOP AT i_cfx_col INTO wa_cfx_col
WHERE (l_where_clause).
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
when i compile this i get an error message as { Statement concluding with "...(l_where_clause)" ended unexpectedly}
Even i changed the initilization of the variable l_where_clause2 to [ l_where_clause2 = 'AND SCENARIO = l_scenario.'. ]
added the end of line demarkation ".", but still i got the same error message.
Is it a limtation in ABAP that i cannot write a dynamic query for the where clause while looping at an internal table?
Regards,
om

Hi savita,
there in no such 1 limitaion in abap for dynamic query .. i think the error meassge is only beacuse of your synatx delcartaion.
>> LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE (l_where_clause).
   count = count + 1.
some business logic implemented using the work     area    wa_cfx_col
   endloop.
afted delclarataion also , in the where statement you should specify both the field name and value bname
   LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE l_where_clause = 'CREATED_BY = l_name' .
   count = count + 1.
hope it helps.

Issue in select query with where clause

Hi guys,
I'm facing an issue while using select query with the where clause. When I'm selecting all the data from the table it returns the correct result. But when I'm using the where clause to get the specific rows from the table it returns no rows. But the data I'm trying to fetch using the where condition exists in the table.
Here is my query which causing the issue,
select * from mytable where myfield = 'myvalue'
But if I use the following query it returns the result correctly.
select * from mytable
Also the myfield value 'myvalue' exists in the table.
I have tried by running this query in both SQL Developer and SQL Plus. I have tried this query in mssql as well. It works perfectly and returns correct result sets for both the queries I have mentioned above. I'm unable to predict the issue as I'm new to ORACLE. Please help.
Thanks,
Ram.

Hi Ram,
I experienced an issue similar to this with a varchar2 field. Some of our records had a hidden newline character at the end of them, which was making queries like the one below fail:
select * from employees
where email = '[email protected]'The best way I found to detect this was to use
select 'XX'||email||'XX' from employeesTo make sure that there were no newlines. But that is just a guess. If you could provide some example table data and the outputs of your selects, it would be helpful.

Sub query in where clause

I have the following code which keeps throwing an error:
select distinct game_code, count(player_id)
from customer_data.cd_nhl_gm_tender_stats t
where
(select distinct player_id
from customer_data.cd_nhl_gm_tender_stats
where season_id = 200818)
group by game_code, player_id
having count(player_id) > 1Error states that there's a missing expression right before the group by, any thoughts?
The subquery is basically used to find a unique player_id value, (so there's no duplicates rows in the result set.)
Sample data;
customer_data.cd_nhl_gm_tender_stats t
Game_code player_id
88484           545454
88484           545454
88484           545454There's obviously other columns in the table above, but ultimatly there is mutliple rows for each game.
I'm just trying to return each game_code where more then one player_id is found.

Michaels2 i'm not sure your code is doing quite what i need
select   *
from   (select   t.*,
                   count (distinct player_id) over (partition by game_code) cnt
            from   cd_nhl_gm_tender_stats t where season_id = 200818)
where   cnt > 1The subquery in the from clause is just selecting every game_code where season_id 200818 and then you add a where clause where cnt > 1 in the main query(whcih doesn't accomplish what I really wanted). What I need is the count of distinct player_id where season_id = 200818 AND cnt of (distinct player_id) over (partition by game_code) cnt > 2**. The issue i'm having is, that i'm not quite sure how to format the code to get these results.
To clairfy what i need one more time ( i didn't explain things well in my original post)...
I want each game_code where a player_id count is greather then two. And as stated earlier the gm_tender_stats table has numerous entries with the same player_id for the same_game code, which is why this makes writing this query a little more difficult.

The issue with using the multiple columns sub-query in WHERE clause

Hi All,
my database version is 10.2.
the problem i am trying to deal with is that when I use multiple column sub-query in the WHERE clause of the SELECT statement, the actual row number returned from the sub-query is different from the whole statement.
And what I found is that, whenever there is NULL in any of those columns returned from the SUB-QUERY, the outer query will just return NULL for that whole row.
Here is an example:
select empno, ename, job, mgr, hiredate, sal, deptno from EMP
intersect
select empno, ename, job, mgr, hiredate, sal, deptno from t;
7782     CLARK     MANAGER     7839     09-JUN-81     2450     10
7839     KING     PRESIDENT NULL 17-NOV-81     5000     10
7934     MILLER     CLERK     7782     23-JAN-82     1300     10
select * from EMP where (EMPNO, ENAME, job, MGR, HIREDATE, SAL, DEPTNO) in (
select empno, ename, job, mgr, hiredate, sal, deptno from EMP
intersect
select empno, ename, job, mgr, hiredate, sal, deptno from t);
7782     CLARK     MANAGER     7839     09-JUN-81     2450          10
7934     MILLER     CLERK     7782     23-JAN-82     1300          10     If I specifically deal with the NULL situations for the columns which might return NULL, I can get the result right.
select * from EMP where (EMPNO, ENAME, job, NVL(MGR,-1), HIREDATE, SAL, DEPTNO) in (
select empno, ename, job, nvl(mgr,-1), hiredate, sal, deptno from EMP
intersect
select empno, ename, job, nvl(mgr,-1), hiredate, sal, deptno from t);
7782     CLARK     MANAGER     7839     09-JUN-81     2450          10
7839     KING     PRESIDENT null   17-NOV-81     5000          10
7934     MILLER     CLERK     7782     23-JAN-82     1300          10     the problem is that, I feel this is a very lame way of handling it.
So, I wonder or am asking if there is any better or standard way to do it?
any help would be highly appreciated.
Thanks

Hi,
As you discovered, INTERSECT treats NULL as a value, but IN does not.
What you did with NVL is one way to handle the situation. If there was a chance that any of the columns could be NULL, then you might prefer something like this:
select      *
from      EMP
where      ( EMPNO      || '~' ||
       ENAME      || '~' ||
       job           || '~' ||
       MGR           || '~' ||
       TO_CHAR (HIREDATE, 'DD-MON-YYYY HH24:MI:SS')
                || '~' ||
       SAL           || '~' ||
       DEPTNO
     ) in (
          select EMPNO      || '~' ||
                 ENAME      || '~' ||
               job     || '~' ||
               MGR     || '~' ||
               TO_CHAR (HIREDATE, 'DD-MON-YYYY HH24:MI:SS')
                    || '~' ||
               SAL      || '~' ||
               DEPTNO
          from     emp
         intersect
          select EMPNO      || '~' ||
                 ENAME      || '~' ||
               job     || '~' ||
               MGR     || '~' ||
               TO_CHAR (HIREDATE, 'DD-MON-YYYY HH24:MI:SS')
                    || '~' ||
               SAL      || '~' ||
               DEPTNO
          from      t
         );This assumes that you can identify some string (I used '~') that never occurs in the strings in these tables.
This is implicitly converting the NUMBERs. That's usually not a good thing to do. but explicitly converting them would make this even more tedious.
You should explicitly convert any DATEs to strings, however. Depending on your default format, and your data, you might get away with implicit conversions even for DATEs, but don't bet on it.
If you had to do this often, you might consider writing a user-defined function:
delimited_string (empno, ename, job, mgr, hiredate, sal, deptno) would return a string like
'7839~KING~PRESIDENT~~17-NOV-1981~5000~10'
This will make the coding easier, but beware: it will make the execution slower.

Change JDBC select SQL query's where clause at runtime

Hi,
I have one JDBC sender channel with Select SQL Query which helps in fetching data from JDE table. We have defined where clause to fetch some particular records i.e. if ABC = NULL then fetch the record.. and then update query is used to turn that flag to "Y" i.e. ABC ="Y" so that next time the channel don't pick the same records again.
Now the problem is that if we want to fetch some records again whose flag has been set to "Y" we cannot change the select query again and again in the production environment.
Is there any way to change the select query of the JDBC channel at runtime e.g. Picking up some flat file where the conditions for the particular records to be picked are defined (ID=123) and changing the WHERE clause of select query in the JDBC channel for those records to be picked without using BPM.
Thank you!
With regards,
Simran

Hi Simran,
Yes, it is possible with the help of store procedure. In SQL Server there is a IF-Else Conditional block, which you can use inside store procedure. Create a SP with 2 additional parameter something like FlagReadAgain and KeyField. Pass the flag always as True or False. For the Key field pass the record key which you want to read again if you are passing the Flag as True else pass it as 0 or whatever.
In the procedure check if the value of flag is True -> If yes, Read the entry with key name specified in where part.
In the else part put the query which you are using for the normal flow.
IF (FlagReadAgain) = TRUE
BEGIN
   SELECT EmpName, EmpAddress
   FROM Employee
   WHERE EmpID = 'E001'
END
ELSE
   BEGIN
     SELECT EmpName, EmpAddress
     FROM Employee
     WHERE Status = 'N'
   END
You may also use the approach which Srini mentioned. Create an application to restore any value to intial stage so that it can be picked up by XI when it poll again.
Choose any approach which you like.

Jitender Chauhan

SELECT QUERY CHECK & WHERE CLAUSE DIFFERENCE.URGENT PLEASE.

My question is ,
IF SBOOK_WA-CARRID = 'LH' CONDITION IS AGAIN PRESENT IN THE DATABASE TABLE ,,,,WILL THE CHECK CONDITION SEARCH IT AGAIN EVEN AFTER FINDING IT IN THE FIRST OF THE TABLE???OR SIMPLY TERMINATE IN THE FIRST TIME THE CONDITION SATISFIES??IF DOES TERMINATE THEN ERRONEOUS RESULT IS BOUND TO COME SINCE ONE MORE RECORS IS UNSELECTED.
SIMILARLY DOES THE WHERE CLAUSE CONTINUE SEARCHING EVEN AFTER HAVING FOUND THE CONDITION ALREADY ONCE IN THE TABLE??
PLEASE HELP ME IN THIS ASPECT.PLEASE CHECK THE TWO DIFFERENT CODES & ANSWER ACCORDINGLY..
SELECT * FROM SBOOK INTO SBOOK_WA.
CHECK: SBOOK_WA-CARRID = 'LH' AND
SBOOK_WA-CONNID = '0400'.
ENDSELECT.
SELECT * FROM SBOOK INTO SBOOK_WA
WHERE CARRID = 'LH' AND
CONNID = '0400'.
ENDSELECT.

Hi,
The Check condition will be true, so it will not going to display the records, it will fill the internal table.
In the Where condition it will fill the Internal table as well as it will display also.
Hope now your query is solved

Error when trying to add a hint to inner query in WHERE clause

I have a form where the WHERE clause in a block starts like:
where seqno in (select seqno from nddf n, restriction r...
I need to add a hint to the inner query like following:
where seqno in (select /*+ ORDERED */ seqno from nddf n, restriction r...
When the query executes. I gets an error message and when I look at the detail error I see: ORA-01722: invalid number
Does anybody know the cause for this. Can I not use hints in inner queries?
Thanks,

Did you mean something like this,
i have tried the below code in forms 10g , as the where clause of 'EMP' block there was no problem.
deptno in (select /*+ ORDERED */ deptno from dept where rownum<2);
Also tried in SQLPlus like below

Af:query - change where clause

Hi,
In my form I have af:query based on a view.
also I have a checkbox that indicates to add or remove sql statements from the 'where clause' of the view.
for example:
my view query is "select * from employees where employees.kod_emp>0"
I need that in case the checkbox is checked the view will look like this:
"select * from employees where employees.kod_emp>0 *and employees.kod_dept = :dept_id*"
and when the checkbox is unchecked the view will return to the original query.
how could I implement it using the same af:query component?

vo.setNamedwhereClause("bindattrubute" , " value" );
vo.executequery();call this method on valuechangelistner of your check box.

Query Builder - Where Clause - Could not format error using date comparison

We've come across a bug in the Query Builder, under the Create Where Clause tab, if you select a column of Date type plus one of the comparison operators =, !=, <, >, <=, >=, BETWEEN or NOT BETWEEN it displays an error in the Logging Page:
Level: Severe
Source: o.d.r.queryBuilder.SQLGenerator
Message: Could not format :2010-09-02 16:20:31.0
Then under the Show SQL tab it doesn't display the date(s) you selected, e.g.
WHERE LAST_UPDATE BETWEEN AND
Also the View Results tab does not display any results.
You can still press Apply to add the SQL as is to the editor window and from there you have to manually code in the date parameters.
We're using the latest version of SQL Developer 2.1.1.64.45 Windows 32bit version with JDK

Simple finder results in huge slow sql query -- why WHERE clause?

Hi all,
wondering about the poor performance of my finder methods I took a look into the SQL that went to the database.
"SELECT DISTINCT OBJECT(p) FROM Person p"
results in
SELECT PersonID, FirstName, LastName, [etc.] FROM person WHERE (PersonID='5354B71CC0A80113008BD3BB11A57FA1') OR (PersonID='5354B893C0A80113008BD3BB3C6918FF') OR (PersonID='5354B910C0A80113008BD3BBC83093BE') OR [etc.]
where all 2000 primary keys are listed. This query costs ~ 4 seconds on my box.
A query without WHERE costs ~ 0 seconds. So why this "WHERE" clause?
Is this a JBoss specific problem? I am using version 3.2.3.
thanx!
Marcus

It's not a bug - it's how JBoss implements it's own
"findAll" methodology. Whether it's a good
implementation or not is open to debate.Really strange.
Anyway all my performance problems disappeared with setting the read-ahead strategy to "on-find". Although I don't fully understand why.

Populate list by executing query with where clause

Hi,
I m populating my list from database table using following command.
EntityManagerFactory emf = Persistence.createEntityManagerFactory("learning", new HashMap());
EntityManager em = emf.createEntityManager();
String query = "select d from Dept d";
List list = em.createQuery(query).getResultList();
My list is getting populated with all of rows in my database table(dept). The problem is, I cant use where clause in my query string.
String query = "select d from Dept d where d.dept_name='ANYNAME'";
Moreover I cant select even indivisual columns by using following line
String query = "select d.dept_code,d.dept_name from Dept d";
It looks like that my query is getting all rows from table as Object.
What to do to
1. put some where clause
2. get some particular colums instead of all columns
3. apply some table joins in query
plz help.

Hi Alex,
I misunderstood your question. You had mentioned "My list is getting populated with all of rows in my database table(dept). The problem is, I cant use where clause in my query string. "
I thought you might not have permissions to modify the code in the class, and that's why I suggested that you could write new classes.
1) write new classes,? means if I need just two columns from a table >(instead of all columns), do I need to write new class with just two >columns (getters and setters)?You can write a SQL statement anyway you want , there are no restrictions in JDBC , so if you need just 2 columns you can write a custom query for that.
"select column1 as a, column2 as be from table_name where column3 = xyz" etc.
2) Is not anyway to write SQL statement like
select dept_code,dept_name from dept where dept_name='anything'The above SQL is correct, it should work.
3) Stored procedures? can I get some example(code) to get an idea >how to implement complex queries with where clause and joinings >using stored procedures?Stored procedures are specific to the database you are using, Oracle has a particular syntax for store procdures.
You can call stored procedures from JDBC also, search on Google for
"Calling stored procedures from JDBC"
4) I m using hibernate. can I get any example of using hibernate own >query?Tutorial on Hibernate Query Language:
http://www.hibernate.org/hib_docs/v3/reference/en/html/queryhql.html

In which order does the query's where clause condition is checked

Hi All,
can anyone tell me in which order does oracle evaluate the where clause condition?
for ex: select * from users where user_type='Admin' and stauts='Enabled'

user9981103 wrote:
The conditions in the WHERE clause are checked in the reverse order of the given order.
i.e; first it will check stauts='Enabled'* and then user_type='Admin'* for your given queryWhy do you believe that?
If there is a sufficiently selective b-tree index on USER_TYPE, the optimizer would undoubtedly use that index to process the USER_TYPE = 'Admin' condition and then check the STATUS column.
If there is a sufficiently selective b-tree index on STATUS, the optimizer would undoubtedly use that index to process the STATUS='Enabled' condition and then check the USER_TYPE column.
If there is a composite b-tree index on (STATUS, USER_TYPE), the optimizer would use that index to process the two conditions nearly simultaneously, though technically the leading column of the index is evaluated first. Of course, if you reverse the order of columns in the index, you get a different evaluation order
If there are bitmap indexes on STATUS and USER_TYPE, Oracle can combine the two indexes and evaluate the two conditions simultaneously.
And that is leaving out tons of query plan options and other optimizer wrinkles.
