Dynamic field in select query

Hi Team,
I have to select dynamic fields from database table GLT0.
This depends on period value given on screen.
If period is 01 then fields will be hsl01.
If period is 02 then fields will be hsl01 and hsl02.
If period is 03 then fields will be hsl01,hsl02 and hsl03 .
so on...till 12..
My code is throwing exception at select query.
"Error in module RSQL of the database interface."
My code :
*"      Type declaration to store field name as per given period
TYPES : BEGIN OF y_fieldname        ,
           fieldname(10) TYPE c    ,
         END OF y_fieldname         .
data t_fieldname TYPE STANDARD TABLE OF y_fieldname   .
DO p_monat TIMES.
     clear w_count .
      MOVE sy-index TO w_count
      IF sy-index LE c_9.
        CONCATENATE c_hsl
                    c_0
                    w_count
        INTO      e_fieldname-fieldname.
        APPEND e_fieldname TO t_fieldname.
      ELSE.
        CONCATENATE c_hsl
                    w_count
        INTO     e_fieldname-fieldname.
        APPEND e_fieldname TO t_fieldname.
      ENDIF.
    ENDDO.

Hi Asik,
I m selecting all fields now as suggestd by u so in one record i have hsl01 to hsl12.
I have to calculate balance into e_glt0_bal-bal .This balance is summation of e_glt0_bal-hsl01 till e_glt0_bal-hsl12 (depending on monat).
I m using logic in process then
my code now :
data:    w_monat_bal type string .
          DO p_monat TIMES.
            MOVE c_01 TO w_count .
            CONCATENATE 'e_glt0_bal-hsl'
                         w_count
                   INTO w_monat_bal.
            ASSIGN w_monat_bal TO <fs_monat_bal>.
            e_glt0_bal-bal = e_glt0_bal-bal + <fs_monat_bal>.
            w_count = w_count + c_01.
          ENDDO.
But <fs_monat_bal> can not be added.
Giving exception :
Unable to interpret "e_glt0_bal-hsl01" as a number.
If I do <fs_monat_bal> type GLT0-hslvt instead to type any
Then assigning from w_monat_bal is not possible.

Dynamic fields in select statement

Hi all,
   In selection screen we are having period as select option.The values for period are 01 to 16. Based on
      the values entered in selection screen for period we need to select HSLXX from FAGLFLEXT.
   For example if we enter 01 to 03 in selection screen then we need to select HSL01 HSL02 HSL03
       from FAGLFLEXT.
Like this we need to select fields dynamically in select statement. Can any one tell me how to restrict fields dynamically.

Swetha

hi Swetha,
the third select statemnet will work for you..
try this..

* With a variable, result: AND rbusa = '5145'
concatenate 'AND rbusa = ' '''' i_tab-zgsber ''''
append where_clause to where_tab.

Dynamic field in select statment.

Hello,
I created a report in which i have two checkboxes in the selection screen. The first checkbox is for the option to bring or not, initial purchase requisitions (BANFN) from EKPO and the second is to bring initial or not, RFQs
(ANFNR). I want the select statment to have this form:
select ...
from ekpo
into g_table
where ..
and dynamic field = " ".
Can this be done ?
i tried to put it as a string but it didnt work. (data: dynamic field type string value "EKPO-BANFN")
P.S i know that it can be by writing the same select code twice.
I just wonder if this can be done by this way
\Regards.

Hey Nick,
I have more conditions than the one i said before , should all be in the lv_where_clause ?
check my code.

DYNAMIC VARIABLE IN SELECT QUERY

hi all,
i m selecting a belnr from one table and want to fire another query on different table wherein this belnr falls somewhere in middle of the whole field.
eg: wa-belnr = 4000
select * from cdhdr where
objectclass = '%wa-belnr%.
i want to select records which contains this belnr.
but %wa-belnr% doesnt work.
pls suggest if theres any solution.

Hi,
select * from cdhdr where
objectclass = '%wa-belnr%.
In the above query use LIKE instead of '='.
Also instead of %wa-belnr% Use like this
<b>DATA: str type string.
concatenate '%' wa_belnr '%' into str.
select * from cdhdr where
objectclass LIKE str.</b>

Update multiple fields using select query efficiently – 9i

I need to populate a table called prop_charact used for synching data to a legacy system.
Prop_charact has fields that are found in a few other tables (no one field is found in more than one table outside of prop_charact). I want to pull the data from the corresponding fields in the source tables and put it into prop_charact. I only want to populate prop_charact with records that have been updated, but want to pull all fields for those records (whether or not that field has been updated). I am getting the list of updated records from a transaction history table.
After getting that list, I was not sure what to do with it.
I put what I want to do in terms of strictly SQL. I am thinking there are more efficient (less system resources) ways of doing this, but I am not sure what to pursue. I can use PL/SQL, but please keep in mind I am limited to using version 9i. Anyone have any hints about what I should look into using instead of just thes particular SQL statements?

How to use Field-symbol with dynamic select query

Can anybody tell me, how to use field-symbols in the dynamic select query.

FIELD-SYMBOLS <fs> { typing | STRUCTURE struc DEFAULT dobj }.
1. ... typing
2. ... STRUCTURE struc DEFAULT dobj
The FIELD-SYMBOLS statement declares a field symbol <fs>. The name conventions apply to the name fs. The angle brackets of the field symbols indicate the difference to data objects and are obligatory. You can declare field symbols in any procedure and in the global declaration section of an ABAP program, but not in the declaration section of a class or an interface. You can use a field symbol in any operand position in which it is visible and which match the typing defined using typing.
After its declaration, a field symbol is initial - that is, it does not reference a memory area. You have to assign a memory area to it (normally using the ASSIGN statement) before you can use it as an operand. Otherwise an exception will be triggered.
eg.
FIELD-SYMBOLS <fs> TYPE ANY.
DATA: BEGIN OF line,
        string1(10) VALUE '0123456789',
        string2(10) VALUE 'abcdefghij',
      END OF line.
WRITE / line-string1+5.
ASSIGN line-string1+5(*) TO <fs>.
WRITE / <fs>.
output:
56789

How to pass the feild names of a select query dynamically?

Hi
How can we pass the feilds names in select query dynamically?
For example in my selection screen i wil be giving the table name, and feilds in that table.....
those feilds should be taken in my select query...
instead of
PARAMETERS : tab_name TYPE ddobjname .
SELECT *
    FROM (tab_name)
    INTO TABLE <newtab>
   UP TO 25 ROWS.
parametrs : feild1 like-------
                 feild2----
i need select feild1 feild2 feild3    FROM (tab_name)
    INTO TABLE <newtab>
   UP TO 25 ROWS.

by the way, contrary to popular belief there is no performance problem when using
SELECT * FROM dbtab INTO CORRESPONDING FIELDS OF TABLE itab WHERE ...
as long as the structure of itab contains only the required fields.
I ran some benchmarks against this and above construct is maybe 0.1% slower (Oracle 10g) than a
SELECT f1 f2 f3 f4 ... FROM dbtab INTO TABLE itab WHERE ...
but is saves you from maintaining a potentially very long field list in your code. So when you need additional fields later on, you just add them to the DDIC structure or type definition and that's it.
Maybe something you want to factor in here.
Cheers
Thomas

Dynamic Select Query including Dynamic Tables with For all Entries

Hello everyone,
I need to create a select query which involves using of Dynamic Tables.
Suppose I have a dynamic table <d1> which consist of let say 10 records.
Now i need to make a select query putting data into another dynamic table <d2>
CONCATENATE keyfield '=' '<d1>' INTO g_condition SEPARATED BY space.
CONCATENATE g_condition '-' keyfield INTO g_condition.
SELECT * FROM (wa_all_tables-name) INTO CORRESPONDING FIELDS OF TABLE <d1>
        FOR ALL ENTRIES IN <d1>
WHERE (g_condition).
But it is giving dump.
Please help me on this....

    A condition specified at runtime has an unexpected format.
What happened?
    Error in the ABAP Application Program
    The current ABAP program "ZNG_CUSTOMWRITE" had to be terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SEMANTICS', was

     clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    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 "ZCOURIER-ZCOURIERID".

Dynamic From statement in select query and/or outer join not working

Dear Experts, I have a select query where the select columns are dynamic, the where condition is also dynamic. It is of the below format:
Select (dynamic columns) INTO <wa>
FROM a inner join b on af1 = bf1
inner join c on af2 = cf2......
WHERE (dynamic conditios)
ORDER BY ( dynamic sort condition).
Now I have to include some tables (dynamically depending on the user input) in the inner join statement which will give description for the selected fields. And these database tables may or may no be empty. So in this case, my select query will not return any data if these tables are empty. And I dont want that.
I tried using outer join for the extra tables but it gave me a runtime error. I also tried forming the inner join statement dynamically but it was not supporting.
Kindly give me pointers.
Thanks

Hey thanks for the reply, but the problem is not solved.
I am already using ( fileds, value) like table in my where condition and the select statement was working properly.
the problem is that now I have to include some tables in the join statement which can be empty and so i want to use Outer join.
But I am getting a runtime error as below:
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SYNTAX', was not
     caught in
    procedure "ZATSCSNG_RFC_READ_TABLE" "(FUNCTION)", nor was it propagated by a
     RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    The running ABAP program wanted to execute a SELECT statement whose
    WHERE condition was (partly) specified dynamically. The part that is
    specified in an internal table at runtime is compared to a field of the
    right table of an LEFT OUTER JOIN. Such comparisons are not supported by
     all database systems and are therefore not allowed.

Absolute dynamic select query with dynamic join and where

Has anyone ever tried creating an absolutely dynamic SELECT query with dynamic Join and Where conditions.
I have a requirement of creating such a query in an Utility Class, and i have written the code. But its throwing my sysntax errors.
Please let me know where am I going wrong OR is it really possible to create such a dynamic Query??
    SELECT (FIELDS) INTO TABLE IT_TABLES
      FROM ( (ME->TABLE1) inner join ( me->table2 )
      on ( on_condition ) )
      WHERE (me->where_fields).
Ags.

It worked for me in a following way:
select * into corresponding fields of table <result_table>
        from (join_string)
        where (l_where).
Where the contents of join_string were dynamically build using concatenation. So it will be something like
concatenate ME->TABLE1 'as a INNER JOIN' me->table2 'as b ON (' into join_string separated by space.
<...>
add here matching/reference colums, something like
concatenate 'a~' me->TABLE1_JOIN_COL into temp1.
concatenate 'b~' me->TABLE2_JOIN_COL into temp2.
concatenate join_string temp1 '=' temp2 into join_string separated by space.
<...>
concatenate join_string ')' into join_string separated by space.
And then use similar approach for l_where variable.
