Dynamic WHERE clause logic in SQL based on ITEM value

Hi,
I have a report based on following SQL query.
   select dept_no,
       dept_name,
       dept_loc
from dept
where dept_loc = :P1_DEPT_LOC
   // If P1_DEPT_LOC is not null, I want the WHERE clause and IF P1_DEPT_LOC is null, then I don't need the WHERE clause.
   // how can I build this logic in same SQLThanks,
Deepak

Deepak,
If p1_dept_loc were a LOV, this would work.
SELECT deptno,
dname,
loc
FROM dept
WHERE ( :p1_dept_loc = '%null%' OR loc LIKE '%' || :p1_dept_loc || '%' )

How to add a dynamic where clause for a sql based VO with group by query?

Hi,
Here is my case, I have a sql query based VO with the query like "select status, count(*) StatusCount from my_table group by status". Now I used the following java code trying to dynamically add the where clause to my VO to filter the rows based the type attribute in my DB table.
vo.setWhereClause("type='MyType1' ");
vo.executeQuery();
Then I got the sql syntax error. Looks like the ADF has added the where clause to the end of my sql so my sql becomes "select status, count(*) StatusCount from my_table group by status where type='MyType1' ". But what I expected was the correct syntax "select status, count(*) StatusCount from my_table where type='MyType1' group by status".
Does anyone know if this is an ADF bug? Or is there any other way to achieve my goal?
Thanks,
Chunyang

Hi,
When you use setWhereClause on the VO, it is applied on top of the VO query. I.e, assume your VO has the following query.
select empno, ename from empNow, if you apply the where clause programatically, only the two attributes that you are using in the select statement could be used. I.e
select * from (select empno, ename from emp) where ename='KING' - VALID
select * from (select empno, ename from emp) where deptno=10 - INVALID (because the inner query - the one you've defined as query for your vo does not have deptno attribute selected)If you would need to set a dynamic where clause, you need to make them available in your select statement / use bind variables.

How to dynamically update columns in a where clause to a SQL query in OSB?

Hi Gurus,
I have a requirement where in we need to dynamically update a where clause to a SQL query in OSB(11.1.1.6.0).
For example:
If the JCA sql string is "select * from emp where emp_id = 100 and emp_status ='Permanent'" now i want to change this where clause and the new query has to be like "select * from emp where emp_name like 'S%' and emp_dept like 'IT' ". basically we need to change the where clause dynamically.
We can also use "fn-bea:execute-sql()" in a xquery but I don't want to use this function as creates a new connection.
I have done some home work and found out --> as per the DOC "http://docs.oracle.com/cd/E23943_01/dev.1111/e15866/jca.htm#OSBDV943" section: "25.5.2 JCA Transport Configuration for Proxy and Business Services", when a business service is created by using JCA, we can see Interaction Spec Properties under JCA Transport Tab. This will have a property "SqlString' and we can over ride it. But I am unable to figure out how to over ride the value. I have tried by using Transport Headers activity but no luck. Please guide me how to achieve this?
Thanks in advance
Surya

I solved my problem.
In my header renderer, I simply added a line to set the text to the object value "label.setText( (String) value );" (where label is an instance of a JLabel.
Thank you to who took some time to think about it.

Dynamic WHERE Clause in a Calendar

I would like to have a Calendar display values based on a dynamic WHERE clause created using PL/SQL anonymous block evaluating the values of items that the user uses as filters. I have done this dynamic SQL for reports and would lke to do the same for a Calendar.

I figured out how to do this.
I created a Hidden Item with the source value of &APP_USER.
named P50_APP_USER.
This is how my query looks now:
SELECT * FROM APX_EVENT WHERE APX_EVENT.STORE_NR IN (SELECT APX_Z.STORE_NR FROM APX_Z WHERE APX_Z.USERNAME = :P50_APP_USER)
And it works.
I got the answer from this thread:
CALENDAR - SQL ORDER BY CLAUSE NOT WORKING

Region Source - Dynamic Where Clause

I cannot find anyway to call a function to dynamically generate a where clause for a SQL Query for the region source. For a given set of html text input types. The where clause builds is build based on the populated values of the textfields, if they are null then it excludes it from the where clause.
For example:
Select a,b,c,d,e,f
from tablename
where function_build_where(&CUSTOMER_NAME., &POSTCODE., &FNAME.)
I keep on getting an invalid relational operator.
If I execute the function directly it returns the correct statement that I want.
Any help will be great
Thanks

Losing my marbles !
I am really stuck here. It makes sense but I cannot get this to work. I have written a very basic example. I keep getting this error message:
ORA-06550: line 5, column 1: PLS-00372: In a procedure, RETURN statement cannot contain an expression ORA-06550: line 5, column 1: PL/SQL: Statement ignored
Debug:
1: begin
2: declare
3: q varchar2(2000) := '';
4: begin
5: q:= 'select PB_ID, PB_NAME from PB';
6: return q;
7: end;
8: end;
Seems like apex wraps a begin end.
Here is the code:
declare
q varchar2(2000) := '';
begin
q:= 'select PB_ID, PB_NAME from PB';
return q;
end;
Is there a way to simply just call a pl/sql function or sp?
e.g. Region Source = GetPBData()
Using dynamic PL/SQL opens up another can of worms as one cannot pre-format any fields, does this mean one has to use the API to control the length of columns etc.
Many thanks

Dynamic where clause - hard-parse

Hi there,
I landed in the middle of a situation that I'm not seeing any solution possible, so I’m turning to you for help.
We have a batch script that occurs once a day that handles a lot of information (we're talking about thousands of data).
In many situations we have to run select's with the where clause dynamically build.
That is, we have a table with something like: ID - COLUMN_NAME - OPPERATOR - COLUMN_VALUE - DEPENDING_VALUE
Our database is unique for a large number of clients (we have about 90% of my country City Hall's and then some more...), and DEPENDING_VALUE depends on each client.
So, for each client, we build the where clause based on that table and then we get the data from another table with something like SELECT ABC FROM XPTO WHERE || WHERE_CLAUSE_BUILD using dynamic sql.
So far so good, except we can have many different combinations of the where clause causing the select to be hard-parse for each client and we are trying to think of a better way to do this. Unfortunately we haven’t found one yet and I’m not seeing any light in the end of the tunnel…
This is kind of difficult to explain, so I hope I was clear enough.
Any help would be greatly appreciated.
Thank you

Hi, thank you for your answer.
We are already using the USING clause and binding.
The (we think kind of stupid) idea we had was:
We created an array of 100 positions.
Then we made a function that get’s the where clause and populates the array making something like:
‘where a = :param1 and b = :param2 and c= :param3’ and so on.
For the remaining positions, we added ‘and 1 = :paramMax+1 and … and 1 = :paramMax+N and …’ and put :paramMax+1.value = 1 and :paramMax+N = 1.
Then, when using the select with the where clause we opened a cursor using :param1.value, :param2.value, :param3.value, … :param100.value
But this still is hard-parsing because I can have:
Select x from y where a = :param1 and b = :param2 and 1 = :param3 …
And for another client
Select x from y where a = :param1 and 1 = :param2 and 1 = :param3 …
The statements are different, that’s why I’m not seeing any solution.
Thanks

Subquery in dynamic where-clause

Hi,
i'm trying to build a dynamic sql-statement in OPEN SQL, which uses a subquery in the dynamic where-clause.
In the following example code the first select works fine, the second one raises an error.
report zerrorforum.
data:
l_var_anzahl
* No Error
select
   count(*)
into
   l_var_anzahl
from
   t000 as t1
where
   t1~mandt in ( select t2~mandt from t000 as t2 where t2~mandt = t1~mandt ).
* Error
select
   count(*)
into
   l_var_anzahl
from
   t000 as t1
where
   ('T1~MANDT IN ( SELECT T2~MANDT FROM T000 AS T2 WHERE T2~MANDT = T1~MANDT )').
The Error Analysis says the following:
The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SEMANTICS', was
not caught and therefore caused a runtime error. The reason for the exception is:
The current ABAP program has tried to execute an Open SQL statement
which contains a WHERE, ON or HAVING condition with a dynamic part.
The part of the WHERE, ON or HAVING condition specified at runtime in
a field or an internal table, contains the invalid value "SELECT".
Is this behaviour documented anywhere? I didn´t find anything.
Or is it a bug?
Klaus-Dieter Lueppens

Hi,
it's not possible. Here is a quote from ABAP documentation from dynamic WHERE condition.
A logical expression can be specified as a parenthesized data object cond_syntax that contains the syntax of a logical expression or is initial when the statement is executed. It has been possible since SAP Web AS 6.40 to specify all logical expressions dynamically, with the exception of the evaluation of a subquery.

Less than or eual to Date issue in dynamic where clause

Dear All,
I have a requirement to search the leave balance information, here date as a parameter. When ever we pass the date as a parameter it should be display all the leave balance information till the parameter date.
Steps I have followed to achieve this requirement
• Created the VO and query as follows
SELECT trunc(paa.creation_date) creation_date, paa.date_start, paa.date_end,
SYSDATE duty_resumption_date, paa.absence_days leave_deducted,
paa.absence_days leave_added, 'Leave Deucted' detail,
paa.absence_days balance_remaining,
fu.user_id
FROM per_absence_attendances paa, per_all_people_f papf, fnd_user fu
WHERE 1 = 1
AND papf.person_id = paa.person_id
AND papf.person_id = fu.employee_id
AND fu.user_id=fnd_profile.value('USER_ID')
And trunc(paa.creation_date) <= TO_DATE((to_char(trunc(to_date(:1)),'DD-MON-YYYY') ),'DD-MON-YYYY')
•     Created the Advance Search Region
•     In the controller of the region, I have captured the go button logic and setting the dynamic where clause as below
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModuleImpl am= (OAApplicationModuleImpl)pageContext.getApplicationModule(webBean);
OAQueryBean oaquerybean = (OAQueryBean)webBean.findIndexedChildRecursive("QueryRN");
if (pageContext.getParameter(oaquerybean.getGoButtonName()) != null)
OAViewObject oaviewobject = (OAViewObject)am.findViewObject("XXLeaveBalanceVO");
String creationDate = pageContext.getParameter("CreationDate");
oaviewobject.setWhereClauseParam(0,creationDate);
oaviewobject.executeQuery();
•     But this where condition is working equal condition to the parameter but it is not working less than condition.
•     When I am running the VO query in Toad it is working the less than condition.
Please help me out to resolve this issue.
Thanks in Advance,

How to create dynamic where clause instead of pragmatically

Hi,
I'm using Jdev 11.1.2.2.0 and my requirement to create a two fields with search button to fetch data as adf table. User need to enter either of the field value and click search button to see his data.
So I created a sql query based view object with 2 bind variables (which are input params) & 2 view criteria (to create dynamically where clause) and then drag on to the page by ExecuteWithParams operation from data controls but couldnt work.
If anyone have idea to build dynamically please let me know.
Amar

User need to enter either of the field value and click search button to see his data.User need to enter either of the field value and click search button to see his data.
Hi Amar,
Is your requirement, creating a query panel with table??
Drag and drop the view criteria(Application Navigator>DataControls> AppModule >NamedCriteria> ViewCriteriaName ) onto the page.
In the context menu, select Query->ADFQueryPanel With Table.. That brings your necessary two columns and Search field with data represented as a table.

If you are using Apex, the for performance (and even query flexibility) it will be better creating a separate reporting region for each unique query. A boolean rendering condition checks the existing bind variables in order to determine if that specific reporting region should be executed.
This results in a reporting region having a proper and dedicated SQL query (no hacking of the where clause) and that region only being rendered for the proper combination of supplied filter criteria.
A slightly more complex, but more flexible approach, is using a generic reporting region that calls a PL/SQL function that creates returns the SQL query for execution and rendering. The approach to this is very similar to constructing a SQL ref cursor (dynamically) for a client. The only difference is that instead of creating the actual ref cursor, the code simply needs to return the SQL source code statement - with bind variables. The Apex run-time does the rest (does the binds and execution and rendering).
If you are not using Apex - you should still consider these approaches. And not hacking a single SQL to cater for all different types of filter conditions.

Dynamic Where clause in 4.6C [Literals allowed but not variables]

Good afternoon-
We have a dynamic select statement that works perfectly in 4.7 ext 2, but is causing a short dump in 4.6C. The error in the short dump says:
The current ABAP/4 program attempted to execute an ABAP/4 Open SQL
statement containing a WHERE condition of the form WHERE (itab) or
WHERE ... AND (itab). The part of the WHERE condition specified at
runtime in the internal table itab contains an invalid
value "HDR_COMP_CODE". Literals are allowed as values, but not variables.
HDR_COMP_CODE is in incoming parameter to the function module that is calling this code. It is of type BKPF-BUKRS.
Here is the code:

        TEXT_LINE(60) TYPE C,

Well, in this case, unless I'm missing something, you do not requre a dynamic WHERE clause. You can use RANGES instead.
report zrich_0001.

How to create VO with multiple dynamic where clauses on select with UNION?

I am trying to implement the View Object for the UNION query that looks like this:
     select a,b,c...
          from t1,t2,...
          where dynamic_where_clause1
     union all
     select a,b,c,...
          from t11,t12, ...
          where dynamic_where_clause2
There are up to 60 input parameters that are used to generate dynamic where clauses. They are actually created by calling PL SQL function.
So far, I was not able to assign both where clauses to the view object. Is there a workable solution for this problem, besides resorting to programmatic View Object?
I understand that recommended way with UNIONs is to wrap both queries into a parent select:
select * from (
     select a,b,c...
          from t1,t2,...
          where ... -- table relationship joints
     union all
     select a,b,c,...
          from t11,t12, ...
          where ... -- table relationship joints
) QRSLT
     where dynamic_where_clause
Unfortunately this approach doesn't work here, since individual selects are producing unmanageable amount of data and resulting query takes forever to complete.

I afraid I would not have any real benefits from using VO if I replace the entire query with every request. Actually, the performance may suffer.
I solved the problem by creating a POJO Data Control and invoking the custom select query from java. Not sure if it is the best approach to the problem, but implementation time is limited and it works.
Actually, this is not the first time I see the need to implement VO with complicated SQL like select with unions and dynamic pieces. It would be nice to find a solution and not resort to workarounds.

Dynamic WHERE clause in .xsql pages

I'm just getting started with XSQL and would like to know if you have more example source code available, or if anyone else knows of a good source.
I'm trying to build a simple search page which accepts values that would normally form the where clause in an SQL statement and send them to an XSQL page which returns the results. The main problem is that I don't know how to specify the column names dynamically.
Please let me know if you've come across this before, I'm sure this is not an unusual problem.
P.S. When's the XML book coming out?

See the "adhoc query" example that comes with the XSQL Servlet in the ./demo/adhocsql directory.
Your query can be:
<xsql:query columns="col1,col10" where="1=1">
SELECT {@columns}
FROM table
WHERE {@where}
</xsql:query>
for example, where the columns and where attribute provide default values for the columns and where parameters. If the user passes in either or both of the parameters in the URL, they override the defaults.

Dynamic where clause in "delete itab where..." variant

Hi, I need to be able to delete the contents of an internal table based on a dynamic where clause. I don't want to loop through the entire table to test each record. Since the delete statement doesn't seem to allow a dynamic "where" clause I am trying to use a macro. I can't get the macro to work either.
I get the following error in my syntax check:
Statement concluding with "...FINAL_STATEMENT" ended unexpectedly.
Is there any way to get this macro to pass the syntax text or accomplish the dynamic delete?
MACRO TO FILTER OUT UNWANTED RECORDS (RETAIL OUTLETS)

    DELETE MY_ITAB WHERE &1.

ADF dynamic where clause for VO query using BC

I'm hoping someone can help me out. I have a read only view object that I want to filter results based on some user choices. For example the user may want to see all results or they may only want to see a much smaller subset. This is for an error dashboard, the smaller subset maybe by application or maybe by application and by error severity. I think I can use a dynamic where clause but I'm not sure, Can someone get me started down the right path, or post an example that I can see.

Hi user,
You can use a dynamic where clause for this, but maybe there is a more practical option. Maybe you can have a fixed where clause, but using a bind parameter, like:
vo.application like :applicationParam. This makes an executeWithParams method available that you can call from your page, and use in the bindings. This parameter you can populate with the results of for example a poplist, with a default value of '%'.
When you do want to use a dynamic where clause, you will need to add a method to the java code of your application module, and make this method available for the client. In this method, you can use findViewObject to retrieve your VO, use VO.setWhereClause to set the whereclause to what you want, and then call VO.executeQuery. This method can then again be called from the page.
Success,
