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 !!

REPORT with dynamic WHERE CLAUSE (run RDF or REP) ?
Hi:
When running a REPORT (myreport.rep) with dynamic where clause using a lexical parameter, I got this error:
REP-1439: Cannot compile .REP or .PLX file as it does not have source
If i run the report specifiying RDF extension (myreport.rdf) the report run successfully! Is this normal ?
If I specify RDF extension will Report Server COMPILE the report everytime I execute it ?
When using dynamic WHERE CLAUSE I will have to run RDF files instead of REP ?
I'm running Reports 9i under Linux, with IDS under Windows.
Waiting Help
Joao OliveiraIt sounds like you are building the .rep files on one platform (windows) and running them on another (linux). The reason that the .rdf file continues to work is that Reports recompiles the PL/SQL within the report when you move from one platform to another or change schemas. .rep files can't be re-compiled in this way so you need to ensure they are compiled successfully when converting them.
You need to convert from .rdf to .rep on the platform that you are intending to run on. Try running rwconverter on the linux platform with "compile_all=yes" to produce the .rep file and running that .rep file. -
Dynamic itab with Dynamic Where clause
Hi, Dear All,

Dynamic where clause: Urgent
Hi,
I am facing a problem with data retrieval in a BADI with dynamic where clause.
I have a variable defined as:
data: lv_where_condn TYPE string.
I concatenate the data in the string based on the user's input and perform the following select:
SELECT *
FROM zd_apo_prodvar1
INTO TABLE lt_data
WHERE (lv_where_condn).
The sy-subrc returns a value 4 although there is data in the system for the users data input.
Earlier it used to give a short dump which I have now take care of with the catch statement.
SAP has suggested the following:
This problem happens if an attempt was made to bind or define a variable character string with a buffer length less than the two-byte minimum requirement. Please check the variable definition in your custom code and increase the buffer size or use a different type.
Any inputs will b appreciated in declaring the dats type for lv_where_condn.

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 PMHi,
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 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.

Is iot possible to use a dynamic where clause in a loop? If so how to you code this?

Moderator message: please read ABAP documentation for your SAP release.
Edited by: Thomas Zloch on Mar 29, 2011 3:20 PMYou 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.

Creating dynamic where clause with string delimiter " ; "
hi...
i need a solution for complex problem like, 1. start_date IN date,
end_date IN date,
shift_type IN varchar2
i will get shift_type as "first_shift" or "first_shift;second_shift" or "first_shift;second_shift;third_shift" ....etc any combination. where fist & second & third shits are nothing but 1 , 2 , 3. i need to find out data between start_date and end_date in combination of shifts ( may be 1;2 or 1;3 or 1;2;3 or 2;3 ...etc) . now i need to write this code in dynamic where clause ...i tried in different ways...but not succeeded. can anybody guide me step by step...or with script.
NOTE: there is a table called "shift" with data like
shift_type shift_mode
1 first_shift
2 second_shift
3 third_shiftHi,
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
If the question involves parameters, give a few different sets of parameters and the results you want for each set, given the same sample data.
It's unclear that you need dynamic SQL at all.
If shift_type is a variable, that can be either a single value or a ;-delimited list (such as '1;3'), you can compare that to a column called shift_column like this:
WHERE ';' || shift_type || ';' LIKE
'%;' || shift_column || ';%'No dynamic SQL or PL/SQL required.
If you really do want to use dynamic SQL, these two pages should gives you some ideas:

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.

How to set dynamic where clause in ADF?
Hi,
I have a View object called BillInfoVO. This has
all the information about who created the request, the time , status etc.,
I need to display this VO in a jsp. But before I display, i need to fileter this
VO results with different where clauses according to the role of the user.
For example, if the role is admin, then
where clause should be 'status = 'Completed, and created by = 'Current user'
If the role is requestor, then
the where clause should be
sales manager id = 'Current user' and
Status != Complete etc.,
Could any one please let me know how I can
dynamically set the where clause to filter the appropirate
result row set in the jsp?
Your help will be greatly appreciated.
Thanks,
venkiYou'll create a service method in your AM that will use the setWhereClause method of a viewobject.
Then you'll expose it as a client method.
Then you'll drag it from your data-control onto a button in your JSF page that will call your page for the query.

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?
/LarsHi 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.

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. -

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.hi prabhu,
this is how u select dynamically...
DATA: COND(72) TYPE C,
ITAB LIKE TABLE OF COND.
PARAMETERS: CITY1(10) TYPE C, CITY2(10) TYPE C.
DATA WA TYPE SPFLI-CITYFROM.
CONCATENATE 'CITYFROM = ''' CITY1 '''' INTO COND.
APPEND COND TO ITAB.
CONCATENATE 'OR CITYFROM = ''' CITY2 '''' INTO COND.
APPEND COND TO ITAB.
CONCATENATE 'OR CITYFROM = ''' 'BERLIN' '''' INTO COND.
APPEND COND TO ITAB.
LOOP AT ITAB INTO COND.
WRITE COND.
ENDLOOP.
SKIP.
SELECT CITYFROM
INTO WA
FROM SPFLI
WHERE (ITAB).
WRITE / WA.
ENDSELECT.

How to create a procedure to output REF CURSOR with any WHERE clause?
I have an requirement like this: I have huge query which need to reuse in my code more than 10 times. This SQL has about 50 lines. Thing is for those 10 odd times sometimes the WHERE clause changes (columns are the same). So I cannot create a view since SQL is not static.
I thought of writing a procedure with a WHERE_CLAUSE input para. I output a sys refcursor by adding the where clause. But I can't do it since you cannot add a where clause like that.
i.e.
PROCEDURE dynamyic_query (p_where_clause IN VARCHAR2, p_out_query OUT SYS_REFCURSOR ) IS
BEGIN
OPEN p_out_query FOR SELECT ......... FROM table WHERE || ' ' || p_where_clause;
END;The above gives error.
How to handle a situation like this???? Any help would be greatly appreciated.I tried this method:
I created a table tab_test which has these records:
TNAME TABTYPE CLUSTERID
ABS_V4_P_ERROR_MESSAGES TABLE
ABS_V4_P_ORG_PARAM TABLE
ABS_V4_P_PARAMETER TABLE
ABS_V4_P_SYS_PARAM TABLE
ACCINTERFACE_PARAMETERS TABLE
ACCOUNTS TABLE
ACCOUNT_EXTRACT_PERIODS TABLE
ACCOUNT_EXTRACT_PERIODS# TABLE
ACCOUNT_EXTRACT_PERIODS_1 TABLE Now I create this proc:
PROCEDURE FORMS_TEXT_DYN_SQL_TEST(p_where_cluase IN VARCHAR2, p_out_cursor OUT SYS_REFCURSOR) IS
v_stmt VARCHAR2(1000);
BEGIN
v_stmt := 'SELECT tname FROM tab_test WHERE tname LIKE ''%ABS_V4%'' AND tabtype = :x';
OPEN p_out_cursor FOR v_stmt using p_where_cluase;
END;I create this code block and run it:
declare
v_tname varchar2(200);
out_cursor sys_refcursor;
begin
forms_text_dyn_sql_test('TABLE', out_cursor );
LOOP
fetch out_cursor INTO v_tname;
exit when out_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_tname);
END LOOP;
end;
/I get correct output:
ABS_V4_P_ERROR_MESSAGES
ABS_V4_P_ORG_PARAM
ABS_V4_P_PARAMETER
ABS_V4_P_SYS_PARAMHowever, when I change the proc like this:
PROCEDURE FORMS_TEXT_DYN_SQL_TEST(p_where_cluase IN VARCHAR2, p_out_cursor OUT SYS_REFCURSOR) IS
v_stmt VARCHAR2(1000);
BEGIN
v_stmt := 'SELECT tname FROM tab_test WHERE tname LIKE ''%ABS_V4%'' AND :y';
OPEN p_out_cursor FOR v_stmt using p_where_cluase;
END;And run this code block:
declare
v_tname varchar2(200);
out_cursor sys_refcursor;
begin
forms_text_dyn_sql_test(' 1 = 1 ', out_cursor );
LOOP
fetch out_cursor INTO v_tname;
exit when out_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(v_tname);
END LOOP;
end;
/I get error:
[1]: (Error): ORA-00920: invalid relational operator ORA-06512: at "ABS.FORMS_TEXT_DYN_SQL_TEST", line 6 ORA-06512: at line 5Looks like you can only put column_name = :z, column_name = :y type values. You cannot it seems replace it with any WHERE CLAUSE????
