SELECT Query - Dynamic Coulmns

Hi
I need to write a query that will have dynamic number of columns depending on the present day of the month that is, if today is 13th November then the SELECT query should have 13 columns.
Regards
Kapil

SQL does not deal with dynamic columns. The number of columns must be determined before data is retrieved so that the SQL engine knows what to get back.
Whilst it's possible to use PL/SQL to write some dynamic SQL this is not really the correct place to be doing what you want. The nature of this requirement lies with a report generating tool, as these are generally designed to produce dynamic SQL in this way.
As suggested, you would be better to write your SQL to produce 31 columns of information and then use your front end GUI to just show the columns that are required, OR use a report generator to dynamically build the query in the first place.

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.

How to make columns in the select list dynamic

Hi
I need to make columns in the select query dynamic.I have three tables.Table 1 contains master information lets say name of group(A group consists of members of various skill sets) and its period(A group is of specific period lets say for 18 months).Table 2 contains different skill sets corresponding to a group i.e there is one to many relationship between table 1 and table 2.Table 3 contains months information of skill sets.For example if skill set 1 is required for 5 months then there will be 5 rows(for each month) in table 3 corresponding to a skill set i.e there is again one to many relationship between table 2 and table 3.Tabale 3 will also contain man month value for perticular month.I need to show all the periods of a group and its sum of man month value for all skill sets.
If group1 is of 6 months (starts nov2006 and ends Apr2007) and has 5 skill sets then there will be one entry in table 1 and 5 entry in table 2(For skill set).For each entry in table 2 there will be 6 entry in table 3(for each month).I need to write a query which would display
Group name nov2006 dec2006 jan2007 feb2007 mar2007 apr2007
Gr1 10 15 21 17 18 22--These are sum of man month of all skill set for a particular groupIf Gr 2 is of 9 months then it would disply all the information in respective months.i.e for group 2 nine months information and group 1 six months information
Pls help
Thanks in advance

How to create a Type Object with Dynamic select query columns in a Function

Hi Every One,
I'm trying to figure out how to write a piplined function that executes a dynamic select query and construct a Type Object in order to assigned it to the pipe row.
I have tried by
SELECT a.DB_QUERY INTO actual_query FROM mytable a WHERE a.country_code = 'US';
c :=DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(c,actual_query,DBMS_SQL.NATIVE);
l_status := DBMS_SQL.EXECUTE(c);
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
FOR j in 1..col_cnt LOOP
DBMS_SQL.DEFINE_COLUMN(c,j,v_val,2000);
END LOOP;
FOR j in 1..col_cnt LOOP
DBMS_SQL.COLUMN_VALUE(c,j,v_val);
END LOOP;
But got stuck, how to iterate the values and assign to a Type Object from the cursor. Can any one guide me how to do the process.
Thanks,
mallikj2

Hi Justin,
First of thanks for your reply, and coming to my requirement, I need to report the list of items which are there in the dynamic select statement what am getting from the DB. The select statement number of columns may vary in my example for different countries the select item columns count is different. For US its '15', for UK it may be 10 ...like so, and some of the column value might be a combination or calculation part of other table columns (The select query contains more than one table in the from clause).
In order to execute the dynamic select statement and return the result i choose to write a function which will parse the cursor for dynamic query and then iterate the values and construct a Type Object and append it to the pipe row.
Am relatively very new for these sort of things, welcome in case of any suggestions to make it simple (Instead of the function what i thought to work with) also a sample narrating the new procedure will be appreciated.
Thanks in Advance,
mallikj2.

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>

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 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.

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

The above given logic of mine works for you, put the code in the If condition and try-
just like below:
IF NOT P_EBELN IS INITIAL.
lt_where = '& = ''&'' '.
REPLACE '&' WITH p_ebeln INTO lt_where.
REPLACE '&' WITH field_value INTO lt_where.
SELECT (lt_sel_list) INTO CORRESPONDING FIELDS OF TABLE <lt_outtab>
FROM (p_tabnam)
WHERE (lt_where).
