How to dynamic create Select SQL statements.

Hi frnds,
I want to make a SELECT statement in which all values I will get dynamically. Like i have two fields on selection screen, one for table name and one for field name. Now I need to make my ITAB according to the table selected and field name selected. So finally my ITAB will be having the field which I chosen from selection screen.
Now how can I make a dynamic ITAB and how to create a dynamic SELECT statement?
It wud be great if you can help me.
Thanks

Here is a sample program....
This will get you started in programming a dynamic internal table as well as dynamic select.
report zrich_0002.
type-pools: slis.
field-symbols: <dyn_table> type standard table,
               <dyn_wa>,
               <dyn_field>.
data: alv_fldcat type slis_t_fieldcat_alv,
      it_fldcat type lvc_t_fcat.
type-pools : abap.
data : it_details type abap_compdescr_tab,
       wa_details type abap_compdescr.
data : ref_descr type ref to cl_abap_structdescr.
data: new_table type ref to data,
      new_line type ref to data,
      wa_it_fldcat type lvc_s_fcat.
selection-screen begin of block b1 with frame title text .
parameters: p_table(30) type c.
selection-screen end of block b1.
* Get the structure of the table.
ref_descr ?= cl_abap_typedescr=>describe_by_name( p_table ).
it_details[] = ref_descr->components[].
loop at it_details into wa_details.
clear wa_it_fldcat.
wa_it_fldcat-fieldname = wa_details-name .
wa_it_fldcat-datatype = wa_details-type_kind.
wa_it_fldcat-intlen = wa_details-length.
wa_it_fldcat-decimals = wa_details-decimals.
append wa_it_fldcat to it_fldcat .
endloop.
* Create dynamic internal table and assign to FS
call method cl_alv_table_create=>create_dynamic_table
             exporting
                it_fieldcatalog = it_fldcat
             importing
                ep_table        = new_table.
assign new_table->* to <dyn_table>.
* Create dynamic work area and assign to FS
create data new_line like line of <dyn_table>.
assign new_line->* to <dyn_wa>.
* Select Data from table.
select * into corresponding fields of table <dyn_table>
           from (p_table).
* Write out data from table.
loop at <dyn_table> into <dyn_wa>.
do.
    assign component sy-index of structure <dyn_wa> to <dyn_field>.
    if sy-subrc <> 0.
      exit.
    endif.
    if sy-index = 1.
      write:/ <dyn_field>.
    else.
      write: <dyn_field>.
    endif.
enddo.
endloop.

How to dynamically execute generated SQL statements using 11gR2 ?

Hello,
I'd like to know if it is possible to do what the following statement intended to do:
select * from (select replace('select empno from emp',
                             '') from dual);in other words, is it possible to dynamically generate and execute a select statement in a from clause ?
thank you for your help,

Hello Aketi,
That is totally WICKED !!
I've been playing with the code you posted, pretty much since you did, trying to figure out how it works. I have some idea of how it works now but, I cannot figure out why I get the set of results, not once but TWICE.
When I run the query you posted above, this is what I get:

How could I find the SQL statement who get this message ?

ORA-01555 caused by SQL statement below (Query Duration=11191 sec, SCN: 0x0854.723b9c32)
... How could I find the SQL statement who got this message ?
Thanks, Paul

ORA-01555 means that the UNDO/ROLLBACK space is not large enough.
This occurs because the SELECT statement is attempting to read the UNDO, but the UNDO has been released (transactions have committed or rolled back) and reused.
The following are SOME of the reasons I have seen this to occur:
1) Updates in a loop, with commits happening in the same loop
- this will mark the UNDO available quickly and quickly reuse it. Then when the SELECT wants to rebuild a block, the UNDO used to rebuild the block has been reused (solution, make the UNDO bigger)
2) A SELECT cursor used to control a loop in which updates are performed, and a 'done' flag is marked against the current cursor record, and commits are performed at the end of each loop, prior to fetching the next record
- same problem as above, but it hits the current process. Same solution
3) A 'month end' activity spike occurs, and all sorts of transactions create updates. There is a report that reports the activity - amusingly it needs to start at the beginning of all the work and updates periodically by doing a huge SELECT up front. This is then used to drive a loop which attempts to get information from the various transactions that have been updated and committed. After a while, the SELECT gets an ORA-01555
- same problem as above and same solution. Get a bigger UNDO segment.
You say this only happens once a month. That should give a hint.
I wouldn't bother with which SELECT statement, as much as which APPLICATIONs are being run when it happens.
One way around this - use 10g and set the guaranteed retention period. All sorts of other things will break, by no more 1555. <g>

How set dynamically created query in GridControl?

How set dynamically created query in GridControl?
Thank you

If your dynamic query is based on an Entity object, then you can probably use RowSetInfo setQueryInfo method.
The argument to this method is a 'Query' object. There are three flavours provided in the oracle.dacf.dataset
package.
oracle.dacf.dataset.QueryViewInfo
defines an updateable SQL query based on a predefined BC4J View Object.
oracle.dacf.dataset.QueryStatementInfo
Creates a view object based on an arbitrary SQL statement.
oracle.dacf.dataset.QueryInfo
Creates a View Object from an Entity Object and additional SQL clauses. The View Object will have
that Entity Object as its sole Entity Object base.
If in your application you are able to specify the name of the entity, then you can use the QueryInfo method to define your
query. Please try the following.
SessionInfo si = ....
void runDynamicQuery()
RowSetInfo rsi = new RowSetInfo();
AttributeInfo ai = new AttibuteInfo(..);
ai.setName(..);
rsi..addChild(ai);
si.addChild( rsi)
rsi.setQueryInfo( new QueryInfo( ...../* include entity name */ .... ));
rsi.setName(....);
rsi.open(true);
grid.setDataItemName(...);
Hope this helps,
Sathish.

How can i use one SQL statement to solve problem?

How can i use one SQL statement to solve the question below?
For a Table named A, there is a column named F(char type).
Now select all the records where F like '%00' and update their F value to '%01'
Just one SQL statement.Do not use PL/SQL block.
How to do that?
Thanks.

What is the data volume for this table?
Do you expect lots of rows to have '%00' as their value?
Following two statements come to mind. Other experts would be able to provide better alternatives:
If you have index on SUBSTR(f, 2):
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) || '01'
WHERE substr(f,
              -2) = '00';If most of the rows have pattern '%00':
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) ||
           DECODE(SUBSTR(f,
                         -2),
                  '00',
                  '01',
                  SUBSTR(f,
                         -2));

How can I write a SQL statement which checks if a table exists?

How can I write a SQL statement which tells me whether a table exists?

execute an sql query: select * from <tablename>
catch the exception n check whether the erroe code
matches the one that occurs for table doesn't exist
that's itHow is your answer any different from the one given in the first reply?
It isn't.
As WorkForFood says DatabaseMetaData has a bunch of methods for getting information about tables but this is more useful when you don't know the names of any of the tables.. it sounds like you do so I would concur SELECT from table is probably the quickest way to go. If it helps the Xopen error should be either S1000 or 42S01 (I think) but I would try and see if there is a specific vendor code for table not found/not exists error and check for that.

How to dynamically create sql statement for Defaulting Segment Values?

Hi,
Navigation:
1) Descriptive/Segments
2) Query for DFF to be modified
3) Uncheck “Freeze Flexfield Definition”
4) (B) Segments
5) Segments Summary form opens
6) (B) open - Segments form opens
Now, here I want to specify Default type as "SQL Statement" and in the default value field I want to use SQL statement with parameters (to evaluate the default value).
The parameters should be pass at runtime from the form in which we have this DFF. The parameters value should be one of the values which get evaluated at runtime in the form window.
Please suggest how we can achieve this?
Or is there any alternative to achieve this?
Thanks!!

Jason,
it is possible, though not so simple as with a report.
What you need to do is to create a pipelined function, that returns your date and count data. This pipelined function can be the base of a pseudo-table, which can be used in a select. For the pipelined function you need to define types for one row and a table to define the return-type for your function:
create or replace type calendar_row as object (date_time date, description varchar2(250));
create type calendar_table as table of calendar_row;
Then you can create the package with the function:
================================================
create or replace package dyn_calendar is
procedure set_query(i_query in varchar2);
function view_source return calendar_table pipelined;
end;
create or replace package body dyn_calendar is
v_query varchar2(100) := null;
procedure set_query(i_query in varchar2) is
begin
v_query := i_query;
end;
function view_source return calendar_table pipelined is
TYPE cursor IS REF CURSOR;
c_cal cursor;
v_date_time date := null;
v_description varchar2(100) := null;
r_cal calendar_row;
begin
open c_cal for v_query;
fetch c_cal into v_date_time, v_description;
loop
exit when c_cal%notfound;
r_cal := calendar_row(v_date_time, v_description);
pipe row(r_cal);
fetch c_cal into v_date_time, v_description;
end loop;
return;
end;
end;
================================================
Now you can set query in a PL/SL region before the calendar:
dyn_calendar.set_query(SELECT count(*), ' || :P8_SOURCE_DATE || ' FROM ' || :P8_SOURCE_TABLE || ' GROUP BY ' || :P8_SOURCE_DATE);
and you can base your calendar on the query:
select * from table(dyn_calendar(view_source))
Good luck,
Dik

Dynamic select sql statement

Hi currently i have a problem with the sql statement.
The field name and the table name of the sql statement will depend on what the user input. We need to find out what records is in tableA columnA and not in tableB columnB.
Below is my sql statement:
SELECT * FROM (TABLEA) INTO TABLE ITABA
WHERE (COLUMNA)
NOT IN ( SELECT (COLUMNB) FROM (TABLEB) ).
=============================================
ColumnA = "the user input the field name"
TableA = " the user input the table name"
TableB = " the user input the table name"
The problem lies at the WHERE clause. The system generate a sql error which says "unable to find the field name".

Hi,
Check the following code:
For dynamic table name....
REPORT demo_select_dynamic_database .
DATA wa TYPE scarr.
DATA name(10) TYPE c VALUE 'SCARR'.
SELECT *
INTO wa
FROM (name) CLIENT SPECIFIED
WHERE mandt = '000'.
WRITE: / wa-carrid, wa-carrname.
ENDSELECT.
For dynamic field list
REPORT demo_select_dynamic_columns .
DATA: itab TYPE STANDARD TABLE OF spfli,
wa LIKE LINE OF itab.
DATA: line(72) TYPE c,
list LIKE TABLE OF line(72).
line = ' CITYFROM CITYTO '.
APPEND line TO list.
SELECT DISTINCT (list)
INTO CORRESPONDING FIELDS OF TABLE itab
FROM spfli.
IF sy-subrc EQ 0.
LOOP AT itab INTO wa.
WRITE: / wa-cityfrom, wa-cityto.
ENDLOOP.
ENDIF.

How to set client within SQL statement without using another pl/sql stmt.

I have a following select statement
SELECT SUM (w.prior_forecasted_costs + w.prior_committed_costs)
FROM xxsuf.job_cost_summary_table w,
apps.pa_periods p,
pa.pa_resources bz,
pa.pa_resource_list_members cz,
pa.pa_tasks dz
WHERE w.project_id = z.project_id
AND w.task_id = dz.task_id
AND dz.task_number '98000'
AND w.resource_list_member_id = cz.resource_list_member_id
AND cz.resource_id = bz.resource_id
AND NOT EXISTS (SELECT NULL
FROM pa.pa_tasks zz
WHERE zz.parent_task_id = dz.task_id)
AND w.resource_list_member_id != 1000
AND p.period_name = w.pa_period
AND p.current_pa_period_flag = 'Y'
Above select statement uses pa_periods view which only works when I set my client using "exec DBMS_Application_Info.set_client_info(83);" in Toad or SQL*Plus session.
I was wondering how can I achieve it within select statement. so that I don't have to use another PL/SQL statement to set my client. Is there anyway to set client with my org id within above select statement ?
Please advise.
--Rakesh

You can simply create a function which calls dbms_application_info and use that in your sql statement as in
SQL> create or replace function set_client_info (i_info varchar2)
   return varchar2
as
begin
   dbms_application_info.set_client_info (i_info);
   return i_info;
end set_client_info;
Function created.
SQL> create or replace view v_emp
as
select * from emp where empno = to_number(sys_context('userenv','client_info'))
View created.
SQL> select ename from v_emp where set_client_info(7788) is not null
ENAME
SCOTT
1 row selected.
SQL> select ename from v_emp where set_client_info(7900) is not null
ENAME
JAMES
1 row selected.

How do i see the sql statements that are run ?

i want to see (in a log file) what are the sql statements that oracle had ran.
how do i do it ? what configurations should i do ? how ?
please help ... thanks

Current SQL statements are viewed in dynamic tables:
SELECT SCHEMANAME, SQL_ADDRESS, SQL_TEXT, last_call_et
FROM V$SESSION, V$SQLAREA
WHERE V$SESSION.SQL_ADDRESS=V$SQLAREA.ADDRESS
A historical log of all SQL statements is recorded in Oracle Archived Logs, and can be viewed using the Oracle Logminer approach. This process requires your database to be in ARCHIVELOG mode, and that Logminer be configured to read the archived logs.

How to tune the following sql statements which has two unions in oracle 10g

I want to know how to make this run faster? Can we add hints? or is it because of any table space? Any help is appreciated.
