Dynamic Query in Loop

My objective is similar as follows -
declare
v varchar2(100) := 'Select sysdate from dual';
begin
for rec in (v)
loop
message(rec.sysdate);
end loop;
end;
The above statements returns the following error -
Encountered the Symbol - LOOP when expecting one of the following -......
Actually i am having a query, which will be created dynamically. I need to execute this query in a loop because i am having some calculation for each row.
plz help.

I guess you are looking for something like this:
DECLARE
TYPE EmpCurTyp IS REF CURSOR;
emp_cv EmpCurTyp;
emp_rec emp%ROWTYPE;
sql_stmt VARCHAR2(200);
my_job VARCHAR2(15) := 'CLERK';
BEGIN
sql_stmt := 'SELECT * FROM emp WHERE job = :j';
OPEN emp_cv FOR sql_stmt USING my_job;
LOOP
FETCH emp_cv INTO emp_rec;
EXIT WHEN emp_cv%NOTFOUND;
-- process record
END LOOP;
CLOSE emp_cv;
END;
But the problem is you can not use dynamic cursors in Forms. Use this feature in a database procedure/function.

Dynamic query in where clause while looping in an internal table.

Hi,
Had a small question : How can i make a dynamic query for the WHERE clause while looping at an internal table.
i want to implement a dynamic where clause query for the below example.
it_cfx_col is an internal table and wa_cfx_col is a work area for it_cfx_col
DATA :
i_cfx_col TYPE TABLE OF cfx_col,
wa_cfx_col LIKE LINE OF i_cfx_col.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
LOOP AT it_cfx_col INTO wa_cfx_col
WHERE CREATED_BY = l_name
AND SCENARIO = l_scenario.
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
Now i want to write a dynamic query for the where clause.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
l_where_clause = 'CREATED_BY = l_name'.
l_where_clause2 = 'AND SCENARIO = l_scenario'.
if l_scenario is not initial.
CONCATENATE l_where_clause l_where_clause2
INTO l_where_clause SEPARATED BY space.
endif.
LOOP AT i_cfx_col INTO wa_cfx_col
WHERE (l_where_clause).
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
when i compile this i get an error message as { Statement concluding with "...(l_where_clause)" ended unexpectedly}
Even i changed the initilization of the variable l_where_clause2 to [ l_where_clause2 = 'AND SCENARIO = l_scenario.'. ]
added the end of line demarkation ".", but still i got the same error message.
Is it a limtation in ABAP that i cannot write a dynamic query for the where clause while looping at an internal table?
Regards,
om

Hi savita,
there in no such 1 limitaion in abap for dynamic query .. i think the error meassge is only beacuse of your synatx delcartaion.
>> LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE (l_where_clause).
   count = count + 1.
some business logic implemented using the work     area    wa_cfx_col
   endloop.
afted delclarataion also , in the where statement you should specify both the field name and value bname
   LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE l_where_clause = 'CREATED_BY = l_name' .
   count = count + 1.
hope it helps.

Using Dynamic Query in For Loop

I have a doubt whether i can use the result from dynamic query in the for loop.
for example,
declare
v_sql varchar2(1000);
v_Id INTEGER;
begin
v_sql := 'select id from table1 where id in ('||v_Id||')';
FOR i in vsql LOOP
dbms_output.put_line(i.id);
end loop;
end;
The above query is possible ?

And here's a basic example of opening up a cursor for your dynamic query...

Single quote in dynamic query

Hi all;
Can u please help me on the following dynamic query code ? I know I am missing the single quote around 2 dates but could not figure out where to put it ! I have tried putting 2 or 3 quotes around 2 bind vars but to no avail.
Want to create a dynamic query to simulate the the following:
select
EMPNO,ENAME,JOB,MGR,HIREDATE from emp where HIREDATE >= to_date('01/01/1981','MM/DD/YYYY') and HIREDATE <= to_date('12/31/1982','MM/DD/YYYY');
dynamic code:
declare
v_q varchar2(4000);
begin
v_q :='select EMPNO,ENAME,JOB,MGR,HIREDATE from emp ';
V_q := V_Q
|| 'where HIREDATE >= '
|| 'to_date(' || :P_DATE1 || ',' ||'''MM/DD/YYYY''' || ' )'
|| 'and HIREDATE <= '

Dynamic Query Doubt

Hi,
I need to write a Dynamic Query to get the data from the table by using the Input date parameters.
LIke,
SELECT* from table where date_start between to_date('12-14-2004','mm-dd-yyyy') AND
to_date('12-15-2005','mm-dd-yyyy');
How can i write the above query in dynamic sql as i will get the two dates as input in my procedure
Help me in this

Or more preferably use bind variables with the
EXECUTE IMMEDIATE as, if the query will be called
many times, the bind variables will prevent hard
parsing of the statement each time (i.e. it will be
quicker to execute).blushadow,
Yes, the execute immediate using bind variables is better/faster than not using bind variables, but your first example outperforms your second one. This is due to the fact that execute immediate really closes all cursors, and in your first example the cursors are kept open (yes, even though you issue a CLOSE cur_test) in the PL/SQL cursor cache.

Unable to retrieve results using dynamic query

Hi Experts,
I have created a custom table and have created a custom bol to integrate it with web ui. I have redefined the dynamic query result method of genil layer. I find the data into LT_RESULT but when I invoke the root list method the LR_OBJECT does not contain the values.
Please see below the code that I have written.

Thanks in advance,

Hi,
Please check your get_objects method of the genil class. I made some changes to my implementation of get_objects method and it fixed the problem.

If I do not check Sort, it works fine. In my apps I need all fields sorted by user, how to fix this problem?
My query as below:
declare
query varchar2(2000):='select';
s_class varchar2(1000);
cursor c1 is select * from demo_preference;
begin
for c1_val in c1 loop
if c1_val.login is not null then
query := query ||' ' || 'login' || ',';
end if;
if c1_val.id is not null then
query := query ||' ' || 'id' || ',';
end if;
end loop;
query := SUBSTR(query, 1, length(query)-1);
s_class := '(NVL(:P2_class, ''%'' || ''null%'') = ''%'' || ''null%'' OR
EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = ''P2CLASSCOL'' AND c001 = class))';
query := query ||' ' || 'from ming.reg_report_view1 where'
|| ' ' || s_class;
return(query);
end;

Maybe the internally mapped column used when you clicked on sort is not shown in the report. Try using aliases when you construct the query string, it could help apex internally in identifying a column even if its order changes for a different user. After all the column order in the code is dynamic and I guess even the no of columns displayed might vary both of which could make sorting on a column identified with a number, invalid.
How about displaying the report query somewhere, so that you know what is the exact query being processed, it might give you better information about the problem.
If the problem persists, then use a collection that is fetched those record using the same query string and change the report to refer the collection and then set column sorting on. This way apex would get confused on what columns are being sorted and it would just sort on a c001..c050 column as though it was a string(yes problems with number columns sorting when you do this).

How to fetch indivdual rows from a dynamic query.

Hi,
I wish to fetch the individual rows returned from a dynamic query.
if my dynamic query is:
dyn_stmt := select col1, col2, col3
from tab1;
The query returns multiple rows.
Then how to fetch individual rows of this query ?
Please explain.

declare
cur_test sys_refcursor;
c1 varchar2(30);
c2 number;
c3 date;
begin
dyn_stmt := select col1, col2, col3 from tab1;
OPEN cur_test FOR dyn_stmt;
LOOP
    FETCH cur_test INTO c1, c2, c3;
    IF cur_test%NOTFOUND THEN
      EXIT;
    END IF;
    -- Process this row
END LOOP;
CLOSE cur_test;
END;

Dynamic query in ABAP

Can we use dynamic query in ABAP?

1. Dynamic where clause
You can use an internal table to build a dynamic where clause:
data: where_tab(30) occurs 1 with header line,
         where_clause(30) type c.
Build the where clause. Will look like this when finished
WHERE ZAFSTMD02 = 'X' AND rbusa = '5145'
With a constant, result: ZAFSTMD01 = 'X'
concatenate 'ZAFSTMD' zcostcheck-zmaaned ' = ''X''' into where_clause.
Append to internal table where_tab
append where_clause to where_tab.
With a variable, result: AND rbusa = '5145'
concatenate 'AND rbusa = ' '''' i_tab-zgsber ''''
append where_clause to where_tab.
Select
select * from zcostfreq
     where (where_tab).
endselect.
Note that you can combine static and dynamic where clauses:
select * from zcostfreq
     where bukrs = '2021' AND
                              (where_tab).
endselect.
2. Using a dynamic table name
This report prints the number og entries in a table. The table name is
specified by a parameter.
data:
l_count type i.
parameters:
p_tab type tabname.
start-of-selection.
select count(*) from (p_tab) into l_count.
write: / 'Number of entries in table ', p_tab, l_count.
3. Dynamic retrieval and writing of data
In this example, data is retrieved from the table selected on the selection
screen, and the contents of the
table is written to the screen.
DATA:
Create variable that can contain referecene to any data
dataref TYPE REF TO data.
FIELD-SYMBOLS:
<row>         TYPE ANY,
<component>   TYPE ANY.
PARAMETERS:
p_tab TYPE tabname.
START-OF-SELECTION.
Create a workarea for the tabel selected on the selection screen
CREATE DATA dataref TYPE (p_tab).
The variable dataref cannot be accessed directly, so a field symbol is
used
ASSIGN dataref->* TO <row>.
SELECT *
    FROM (p_tab) UP TO 10 ROWS
    INTO <row>.
    NEW-LINE.
    DO.
    Write all the fields in the record
      ASSIGN COMPONENT sy-index
        OF STRUCTURE <row>
        TO <component>.
      IF sy-subrc <> 0.
        EXIT.
      ENDIF.
      WRITE <component>.
    ENDDO.
ENDSELECT.
4. Dynamic SELECT
TYPES:
BEGIN OF st_bseg,
    bukrs LIKE bseg-bukrs,
    belnr LIKE bseg-belnr,
    dmbtr LIKE bseg-dmbtr,
END OF st_bseg.
DATA:
sel_list   TYPE STANDARD TABLE OF edpline,
li_bseg    TYPE STANDARD TABLE OF st_bseg,
l_bseg     TYPE st_bseg.
START-OF-SELECTION.
APPEND 'bukrs belnr dmbtr' TO sel_list.
SELECT (sel_list)
    FROM bseg UP TO 100 ROWS
    INTO TABLE li_bseg.
LOOP AT li_bseg INTO l_bseg.
    WRITE : / l_bseg-bukrs, l_bseg-belnr, l_bseg-dmbtr.
ENDLOOP.

Display results from dynamic query created and executed inside procedure

Hi;
I have created this code:
CREATE OR REPLACE PROCEDURE RunDynamicQuery(Var1 IN VARCHAR2, Var2 IN VARCHAR2, VAR3 IN VARCHAR2) AS
-- Do something
-- That ends up with a variable holding a query.... (just an example)
MainQuery :='select sysdate from dual';
end RunDynamicQuery;
How can I run this procedure and see the result on the dymanic query generated inside it?
BEGIN
compare_tables_content('VAR1','VAR2','VAR3');
END;
Expected Output for this given example:
20-05-2009 11:04:44 ( the result of the dymanic query inside the procedure variable MainQuery :='select sysdate from dual';)
I tested with 'execute immediate':
CREATE OR REPLACE PROCEDURE RunDynamicQuery(Var1 IN VARCHAR2, Var2 IN VARCHAR2, filter IN VARCHAR2) AS
-- Do something
-- That ends up with a variable holding a query.... (just an example)
MainQuery :='select sysdate from dual';
execute immediate (MainQuery );
end RunDynamicQuery;
BEGIN
compare_tables_content('VAR1','VAR2','VAR3');
END;
Output:"Statement processed'' (no sysdate displayed ! )
Please consider that the collums in the query are always dynamic... PIPELINE Table would not work because I would need to define a container, example:
CREATE OR REPLACE TYPE emp_tabtype AS TABLE OF emp_type;
FUNCTION RunDynamicQuery (p_cursor IN sys_refcursor)
RETURN emp_tabtype PIPELINED
IS
emp_in emp%ROWTYPE;
BEGIN
LOOP
FETCH p_cursor
INTO emp_in;
EXIT WHEN p_cursor%NOTFOUND;
PIPE ROW (...)

That would be a nice solution, thanks :)
''For now'' I implemented like this:
My dynamic query now returns a single string ( select col1 || col2 || col3 from bla)
This way I don't have dynamic collumns issue, and from business side, this ''string'' format works for them.
This way I can use the pipelines to get the result out...
OPEN myCursor FOR MainQuery;
FETCH myCursor
INTO myRow;
WHILE (NOT myCursor%notFound) LOOP
PIPE ROW(myRow);
FETCH myCursor
INTO myRow;
END LOOP;
CLOSE myCursor;

Dynamic query and Open Cursor fetch into ??

Hi;
I think we took the wrong turn some were... because looks like a dead end...
What I need to do:
Create a procedure to compare two generic tables in diferente databases and find rows that have diferent data.
(No restritions on what tables it might compare)
What I have done:
CREATE OR REPLACE PROCEDURE COMPARE_TABLES_CONTENT_V3(
tableName_A IN VARCHAR2, tableName_B IN VARCHAR2, filter IN VARCHAR2) AS
-- Get all collumns present in [TableName_A]
-- This is necessary to create a dynamic query
select column_name bulk collect
into v_cols1
from all_tab_columns
where table_name = v_tab1
and owner = nvl(v_own1, user)
order by column_id;
-- If there is no columns in table A ... them no need to proceed
if v_cols1.count = 0 then
dbms_output.put_line('[Error] reading table ' || tableName_A ||
' collumns information. Exit...');
return;
end if;
-- Collect Collumns information by ',' separated, for the query
for i in 1 .. v_cols1.count loop
compareCollumns := compareCollumns || ',' || v_cols1(i);
end loop;
-- Create the query that gives the diferences....
getDiffQuery := 'select ' || compareCollumns ||
' , count(src1) CNT1, count(src2) CNT2 from (select a.*, 1 src1, to_number(null) src2 FROM ' ||
tableName_A ||
' a union all select b.*, to_number(null) src1, 2 src2 from ' ||
tableName_B || ' b) group by ' || compareCollumns ||
' having count(src1) <> count(src2)';
Whats the problem?
I'm lost...I can access the query using debugging on the oracle procedure... and run it OK on a new SQL window. No problem here... its perfect.
But I dont know how to access this information inside the procedure, I need to format the information a bit...
I try a cursor...
open vCursor for getDiffQuery;
fetch vCursor into ??????? -- Into what... query, columns and tables is all dynamic...
close vCursor;
Any ideas..

Making the issue more simple....
At this point I have a oracle procedure that generates a dynamic sql query, based on the table names passed by parameter.
getDiffQuery := 'select ' || compareCollumns || (.....)
end procedure;
This ''getDiffQuery'' contains a query that gets the diferences in the tables. (Working fine)
I would like to access this information in the same procedure.
I cant use cursor because the table, columns... actualy all is dynamic based on the generated query:( !

Using jquery FullCalendar in APEX with dynamic query

Hi,
I am trying to implement jquery FullCalendar in APEX and came across thie following post but I am unable to get the events to work. I would really like to see it working with an Application_Process:
How we can highlight events in Calendar
Currently I created an Application Process that simply calls a DB table and convert it into json format.
DECLARE
v_sql varchar2(400);
BEGIN
v_sql := 'SELECT * FROM CAL_FEED';
apex_util.json_from_sql(v_sql);
END;
But I am unsure how to add the events via an Application_Process.
I have tried the following in numerious ways (events:function, url feed, etc). It does work if I just do an array but would like it as a dynamic query.
$('#calendar').fullCalendar({
events: "http://server:8080/apex/f?p=101:53:4352610578859707:APPLICATION_PROCESS=IAT_TEST_CAL_FEED"
Thank you in advance,
Jimmy

Hi,
I was able to get the events into Fullcalendar with an Application Process but not sure if this would scale well with alot of events.
Would someone be able to tell me if there is a better way?
I am currently using an On Demand Application Process called IAT_TEST_FEED:_
DECLARE
lv_cal_list VARCHAR2(16000);
lv_return_str VARCHAR2(32000);
BEGIN
FOR i IN (SELECT "CAL_FEED"."ID" as ID,
"CAL_FEED"."title" as caltitle,
"CAL_FEED"."start" as calstart,
"CAL_FEED"."end" as calend
FROM "CAL_FEED")
LOOP
lv_cal_list := lv_cal_list || '{"id":' || CHR(39) || i.ID || CHR(39) || ',' ||
' "title":' || CHR(39) || i.caltitle || CHR(39) || ',' ||
' "start":' || CHR(39) || i.calstart || CHR(39) || ',' ||
' "end":' || CHR(39) || i.calend || CHR(39) || '},';
END LOOP;
lv_return_str := '[' || RTRIM(lv_cal_list,',') || ']';
htp.prn(lv_return_str);
EXCEPTION WHEN OTHERS THEN
htp.prn('error');
END;
In a HTML Region on a page within the Region Header:_
<link rel="stylesheet" type="text/css" href="#WORKSPACE_IMAGES#fullcalendar.css" />
<script type="text/javascript" src="#WORKSPACE_IMAGES#ui.core.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#ui.draggable.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#ui.resizable.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#jquery.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#fullcalendar.js"></script>
<script type="text/javascript" src="#WORKSPACE_IMAGES#fullcalendar.min.js"></script>
<script type='text/javascript'>
$(document).ready(function() {
$('#calendar').fullCalendar({
events: function(start, end, callback) {
$.ajax({
type: "POST",
url: "wwv_flow.show",
dataType: "json",
data: {
p_flow_id:$('#pFlowId').val(),
p_flow_step_id:$('#pFlowStepId').val(),
p_instance:$('#pInstance').val(),
p_request:"APPLICATION_PROCESS=IAT_TEST_FEED"
success:function(calevents){
$.each(calevents, function(i, calevent){
$('#calendar').fullCalendar('renderEvent', calevent, true);
</script>
The line within the ajax call is basically where my concern would be
$('#calendar').fullCalendar('renderEvent', calevent, true);
Thank you,
Jimmy
