Database Adapter - Dynamic where clause

The database adapter needs to support a search facility.
The user can search by any one of the following
1) Date Range
2) Primary Keys
3) user who created
Based on the above options, a query needs to be dynamically created in Database adapter
Date Range
select column1, column2 from emp where createddate > ... and createddate < ....
Primary Key
select column1, column2 from emp where empid in (1,2,3)
* user who created*
select column1, column2 from emp where userid= 456
The conditions after the where clause vary dynamically.
The pure sql option does not seem to support something like
select column1, column2 from emp #whereclause
Is there a way to do this in the Database Adapter?

If you are using SOA Suite 11g you can use query by example option to achieve part of that.
It support only equality check but on dynamic number of fields

OVD database adapter and WHERE clause

Hi all,
We're using OVD 11g, and have a database adapter defined against a table in an Oracle schema. The adapter correctly maps columns to LDAP attributes and creates a virtual directory.
However the table contains users we don't want to appear in the directory. We have no control over the data in the table hence we cannot remove the unwanted users from the source.
Is there any way we can specify a WHERE clause in the database adapter which limits the users pulled out of the table and created in the virtual directory? Something like WHERE organisation = 'Company A'.
Thanks
Alan

You can specify LDAP filters in Routing Include/Exclude in Adapter configuration which will eventually translate into where clause for the database adapter.
For example if you want to exclude users from organization A all you have to do is Add an LDAP filter for that organization in Routing Exclude...
Same is the case for Routing Include.
Hope this helps,

Dynamic where clause problem?

Hi all,
I am using 4 parameters for the attrition rate report of an employee on the selection screen.
Level
Grade
Position
Salary Range (pa0008-ansal)
i have filled the values of level, grade, position, from database tables at the initialization event.
And for the salary range i hardcoded them to 0-5000, 5001-10000 etc.. and so on.
and then showed all 4 parameters are listbox on the selection screen.
now the first 3 parameters are from infotype pa0001 and the last is from pa0008.
Now I want to select pernr, persg ,persk ,plans, begda ,endda fields from infotype pa0001, and 'ansal' field from pa0008 , with the help of a dynamic where clause, is it possible, because here it might be needed for a join as well.
Please help me out with some sample coding help.
Regards
Tarun

    FROM pa0001 AS p1 JOIN pa0008 AS p8 ON p1~pernr = p8~pernr
    WHERE (lv_query) .
<Added code tags>
Now in case of salary slab, i have ranges like 0-5000 , 5001-10000 and so on and I showed it as a listbox on sel. screen.
So how can I read the figure after the '-'?????
And also review, if for the previous 3 parameters it is correct, or it can be shortened and accurated.

Loop with dynamic where clause

hi,
In a program we need to use a loop into an internal table with a where condition is decided on run time.
"Select" from database table is using dynamic where clause and it is working fine.
For the loop part does any one have any idea on this? if we can have dynamic where clause in a loop into internal tab?
Thanks

Hi,
You can't use 'loop where' dynamically .
Have you already tried to use Ranges and CHECK statement?
Like:
First mount range options;
Loop at <table>.
Check using the range.
endloop.
Maybe it's works for you !!

Dynamic Where clause - from third party system

I have internal table A with fields I am getting from legacy system
field1
field2
field3
field4
fieldn
and i am getting a condition table (Where clause conditions) from a legacy system thru an RFC call.
and in the RFC i need to delete records from internal table A using this where clause
and where clause condition table(is 72 char length single field table) from legacy system looks like the following
         ( FIELD1                          BETWEEN '01' AND '05' ) AND
     FIELD1                         NE '06'
     AND ( FIELD4                     EQ 'BU' )
     AND ( FIELD5                      BETWEEN '001' AND '009' )
How could i delete entries from internal table A using this where clause conditon table mentioned above
a®

Hi a®s,
yes, thats what I thought of: Generate subroutine Pool.
I did not elaborate on the fact that dynamic where clauses are allowed only for database selections. That means that FUNCTION 'FREE_SELECTIONS_WHERE_2_RANGE' can't be used either.
But if you generate a subroutine, you can generate TYPE and DATA declarations as well. This gives you the ability to have static where condition for the DELETE itab WHERE statement.
If the type vaies during runtime, the generation may vary too.
I think you are able to do the coding for this.
On the other hand, Thomas' 'slick' proposal using a temporary database table and a subsequent SELECT ... WHERE (<dynamic where clause) may be easier to implement.
BTW: Are ther release notes on ABAP720?

Dynamic WHERE clause in SELECT statement

Hi,
I need to extract (SELECT) all the products in different salesorganizations. Since a product can be available in more than 1 salesorg I have created several properties in the PRODUCT dimension - 1 for each salesorganization (naming: Sxxxx where xxxx is the salesorganization number).
Since I need to prefix the salesorganization property with an "S" I have created a property on the SALESORG dimension called SALESORG.
Therefore I need to create a dynamic WHERE clause in the SELECT statement. Currently my script is:
*SELECT(%SORG%, "[SALESORG]",SALESORG, [ID]=%SALESORG_SET%)
*SELECT(%PROD%, "[ID]",PRODUCT, [%SORG%]="X")
My first SELECT find the Sxxx (equal to the property I need in the PRODUCT dimension). My second SELECT uses the variable in the first SELCT statement to use the correct property for the WHERE clause.
Unfortunately the code is not validated - any suggestions?
/Lars

Hi Lars,
If you run it from a DM package without validating it, does it still work? I would bet it does.
If this is the case I would open a message with SAP (it would be an enhancement request). Until they fix the validation code, you would just have to live with the script not validating.
Cheers,
Ethan

And having an open ended search function on a web page is also not a great idea.
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 select query

Hi
I'm trying for a dynamic query and in the dynamic where clause i'm checking a field for constant.....for instance if i wanna to use WERKS EQ '0478' how to declare it in dync where clause. i tried for the following:
SELECT (TAB_FIELD) INTO TABLE DITAB UP TO 10 ROWS FROM (TAB_NAME) WHERE (CONDI).
heree CONDI = 'werks eq 0287' . in this case the query fails as the werks shud be equal to '0287' and not just 0287. How to handle this? i tried for the following
CONDI = 'werks eq " '0287' " ' but no luck as it is not a valid stmt as i knew.

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

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:

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 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
Edited by: Chunyang on Dec 13, 2012 9:09 PM

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.

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:

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 "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?

Dynamic where clause in Loop

Is iot possible to use a dynamic where clause in a loop? If so how to you code this?
i.e. Loop at itab in wa where (dynamic_where_clause)...
    endloop...
Moderator message: please read ABAP documentation for your SAP release.
Edited by: Thomas Zloch on Mar 29, 2011 3:20 PM

You should be aware that a LOOP AT ... WHERE is not an optimized access .
+ because on a standard table there is not sort order,
   so the loop goes over the whole table and does
   something when the condition is fulfilled
+ it is optimzed for sorted tables, but only for one key!
=> so your idea must have bad performance!
If this is not a problem, then you can solve the problem
in the following way:
loop at table
   if ( dynamic condition )
   endif.
endloop.
But maybe is dynamic condition is not necessary, but
a some fixed if-conditions are also o.k.

Dynamic Where Clause in SQR

How to construct dynamic WHERE clause in our sqr programming ?
In my run control table I am having parameters fromdate, thrudate [mandatory parameters] and location as [Optional Parameter] how can I declare dynamic where clause to achieve this could any one help me with coding ? Here is my sample coding
Begin-Procedure Main
if $prcs_process_instance=' '
do askvalues
else
do getvalues
end-if
End_Procedure Main
Begin-Procedure askvalues
input $frmdate 'Enter From Id' type=text format=number !Mandatory Parameter
input $todate 'Enter To Id' type=text format=number !Mandatory Parameter
input $loc 'Enter Location' value=text !Optional Parameter
End-Procedure
Begin-Procedure getvalues
Begin-Select
FROMDATE
THRUDATE
SQR_LOCATION
let $frmdate=&FROMDATE
let $todate=&THRUDATE
let $loc=&SQR_LOCATION
let where=-------------------------- ?
FROM
PS_PROCESS_TBL WHERE OPRID=$PRCS_OPRID AND RUN_CNTL_ID=$PRCS_RUN_CNTL_ID
End-Select
End-Procedure getvalues
Begin-Procedure selectall
BEGIN-SELECT
SQR_EMPLID
SQR_FNAME
SQR_LNAME
SALARY
FROM
PS_SQR_FIRST_TBL WHERE SQREMPID BETWEEN $frmdate AND $todate
END-SELECT
End-Procedure selectall

SQR will understand Where Clause as dynamic, when you include it in Square Brackets []
In your case, since fromdate & thrudate are mandatory values, I would code like this
let $frmdate=&FROMDATE
let $todate=&THRUDATE
let $loc=&SQR_LOCATION
let $Where_Clause = 'SQREMPID BETWEEN' || ' ' || $frmdate || ' ' || 'AND' || ' ' ||$todate
if $loc != ''
let $Where_Clause = $Where_Clause || ' '|| 'AND' || ' ' || 'LOCATION = ' || $loc
end-if
Now you can use this Dynamic Where Clause in which procedure you want. Only thing is you need to encode the where clause with brackets([$Where_Clause])
