HELP IN DYNAMIC SQL....PLEASE HELP

upd_str := upd_str||'total_prv_mth_amr = nvl(total_prv_mth_amr,0) '||'+ nvl('||p_upd_prev_mth||',0),';
EXECUTE IMMEDIATE upd_str;
IN THE ABOVE IAM GETTING VALUE ERROR BECAUSE total_prv_mth_amr IS A DATABASE NUMBER COLUMN WHERE AS P_upd_prev_mth IS A VARCHAR2 WHOSE VALUE IS GOT AT RUNTIME. i NEED TO ADD BOTH THESE TOGETHER. HOW DO I DO THAT ?? PLEASE HELP ME

I don't think that's the problem. Oracle is quite capable of turning a varchar2 value into a number with a to_number(); it's called implicit conversion. ORA-1722: INVALID NUMBER most likely indicates that p_upd_prev_mth contains data that is not a valid numeric value e.g. letters, spaces, etc.
This is why we should also design a databases so that numeric data is held in a NUMBER column.

Dynamic sql please help

hi i want to write a stored procedure where i should return a reference cursor.... (var_refcursor)
i have to dynamically generate where conditions inside my stored procedure so i did something and finally generated the where conditions and saved it in a string
var_filter ='empno=value and ename=value and dept= value ) <--------- my string looks like this
now can i write like this?
execute immediate 'select * from table_emp where var_filter ;' into var_refcursor;
return var_refcursor;
2nd question) can i declare a cursor like this
cursor c1 is ( select distinct department as dept from dep_table;
minus
select distinct department as dept from emp_sample ; )
3rd question) how do i test the stored procedure whether it is returning the reference cursor or not..?( i want to see the rows that it returns

Need generic dynamic sql query to generate nodes depending on dealer levels

Input table:
create table #test(dealerid integer ,dealerlvl integer)
insert into #test values(1,1)
insert into #test values(1,2)
insert into #test values(1,3)
insert into #test values(1,4)
insert into #test values(2,1)
insert into #test values(2,2)
insert into #test values(2,3)
insert into #test values(2,4)
insert into #test values(2,5)
insert into #test values(2,6)
go
create table #test2(dealerid integer,node integer,prntnode integer,dealerlvl integer)
insert into #test2 values (1,234,124,2)
insert into #test2 values (1,123,234,1)
insert into #test2 values (1,238,123,2)

insert into #test2 values (2,245213,24353,5)
insert into #test2 values (2,2213,245213,6)
Expected result :
I have two test case here with dealerID1 and dealerID 2
Result for DealerID1
Result needed for DealerID2:
the levels for dealers might change (Dealer1 has 4 levels, and Dealer 2 has 6 levels) so i need to create an dynamic sql query which lists each node as separate columns depending on the levels.
I have hacked the query to give the result I need
select a.dealerid,a.node as Lvl1,b.node as lvl2,c.node as lvl3,d.node as lvl4
from #test2 a
join #test2 b on a.node=b.prntnode
join #test2 c on b.node=c.prntnode
join #test2 d on c.node=d.prntnode
where a.dealerid=1 and a.dealerlvl=2
select a.dealerid,a.node asLvl1,
b.node as lvl2,c.node as lvl3,d.node as lvl4,e.node as lvl5,f.node as lvl6--,a.dealerlvl,a.dealerid
from #test2 a
join #test2 b on a.node=b.prntnode
join #test2 c on b.node=c.prntnode
join #test2 d on c.node=d.prntnode
join #test2 e on d.node=e.prntnode
join #test2 f on e.node=f.prntnode
where a.dealerid=2 and a.dealerlvl=3
I am sure there is a better way to do this with dynamic sql. please help.

Dynamic sql in a trigger ...please help

HI All,
I've got a really large table called 'shop' of the form
id number, product1_cost number, product2_cost number,product3_cost, product4_cost....and so on until product20_cost,
product1_desc, product2_desc....and so so on until..product20_desc, active, start_date, end_date, usercreated,
useramended.
I have now created a new application. The new table is called 'products' which has an id, cost, description, oldproductid, shopid
I need a trigger on the table shop so that if anyone uses the old application, it automatically creates the product rows in my new table 'products'
Not all the product fields on the 'shop' table have data so I only want to migrate data if necessary.
The trigger would do the following:
1. Loop through all the products, if the product was updated and product number does not exist on 'products.oldproductid' then create a new record in products
2. If product was updated and product number does exist then simply update the product details.
I have got the trigger to work with product1. However, I'm finding it difficult to write some sort of dynamic sql that would
do the same check on all 20 products without having to repeat the code 20 times.
can someone help?

Hi All,
Thanks about your advice on the relational design. However, this is only a temporary fix. The old shop table was created about 10 years ago by someone else. Our users have to use the old pages for about 2-3 weeks and therefore I need a quick fix that will create the products on the new tables.
The other problem I have is that another powerbuilder based applicated also uses the same tables and that application is being modified to use the new tables but not until another 3 weeks. To ensure both systems are available in parallel, I have to implement this temporary solution.
B_Binoy, you seem you have a solution there but I didn't quite get it. I tried putting the whole pl/sql block in a string, replacing the '1' in product 1 using a variable x and then using execute immediate but because of the :new and :old bind variables, it kept giving me errors like 'variables not bound' etc. If you don't mind, please can you expand on your solution?
Many Thanks

Dynamic sql giving error --please help

Hi ,
I have written the following code --
CREATE OR REPLACE FUNCTION tabcount (
tab IN VARCHAR2, field IN VARCHAR2 ,whr IN VARCHAR2)
RETURN INTEGER
IS
retval INTEGER;
BEGIN
DBMS_OUTPUT.PUT_LINE ('whr' ||whr);
DBMS_OUTPUT.PUT_LINE ('field1' ||field);
EXECUTE IMMEDIATE
' SELECT COUNT(*) FROM ' || tab ||
' WHERE ' || field || 'like '/'%'||whr ||'%'/''
INTO retval;
DBMS_OUTPUT.PUT_LINE ('countis!' ||retVal);
RETURN retval;
END tabcount;
It is giving the following error--
ORA-00920: invalid relational operator
ORA-06512: at "TABCOUNT", line 10
ORA-06512: at line 2
I am not sure how to enclose the like operator within the single quotes.Double quotes is not working for me.
Thanx in advance,
Ira

Offhand, it looks like you may still have some syntax problems -- probably need a blank space before the WHERE --maybe some other stuff too.
What you need to do to debug it is this (and this works just about anytime you are having trouble with dynamic SQL):
1. store the sql statement in a variable.
2. Use DBMS_OUTPUT to display your select statement BEFORE calling execute immediate.
3. copy/paste that select into a separate window and run/debug it.
4. Once you know what is wrong with that statement, go back and fix the code accordingly.
Have fun,

Need help on Dynamic SQL Cursor in Forms

Hi All,
I am trying to execute Dynamic SQL Cursor in forms using EXEC_SQL built in.
I have a cursor for example:
'select * from supplier where supplier = '||p_supplier||' and processing_order = '||p_order
My code is
cur_num := Exec_SQL.Open_cursor;
sql_order := 'select * from supplier where supplier = '||p_supplier||' and processing_order = '||p_order;
EXEC_SQL.PARSE(cursor_number, sql_order);
EXEC_SQL.DEFINE_COLUMN(cur_num ,1,ln_Supp_Id);
EXEC_SQL.DEFINE_COLUMN(cur_num ,2,ls_Suppl_Name,30);
EXEC_SQL.DEFINE_COLUMN(cur_num ,24,ls_exchange,20);
sql_count := EXEC_SQL.EXECUTE(cur_num );
While EXEC_SQL.FETCH_ROWS(cur_num ) > 0 Loop
        EXEC_SQL.COLUMN_VALUE(cur_num ,1,ln_Supp_Id);
        EXEC_SQL.COLUMN_VALUE(cur_num ,2,ls_Suppl_Name);
        EXEC_SQL.COLUMN_VALUE(cur_num ,24,ls_exchange);
End Loop;
EXEC_SQL.CLOSE_CURSOR(cur_num );
In this case I have to write 24 Define Columns and 24 Column value. Is there any way to assign them to %rowtype at one time as I need all coulmn of the table.
I had similar case on multiple tables.
Please help me
Thanks,
Maddy

I need this dynamic sql because p_supplier and p_order values changes at run time
I do not understand. Is this a simplified sample or the real thing? You do know that you can pass variables to cursors:
cursor test is
select * from supplier where supplier = p_supplier and processing_order = p_order;
or does e.g. p_supplier hold other parts of the query?
cheers

Help Needed in Dynamic Sql or alternate to Dynamic Sql

Hi Am working in sqlserver 2008 R2 and here is my Table structure and SPC
;create table SalaryReport(IdSalary int primary key identity(1,1),
IDMainCompany int,IDSubCompany int,Salary money,Incentive int,NoofEmployees int, SalaryDate datetime, Creditscore int );
insert into SalaryReport (IDMainCompany,IDSubCompany,Salary,Incentive,NoofEmployees,SalaryDate,Creditscore)

'2014-01-01' as SalaryDate, 30 as Creditscore)
Sample Test Script:
DECLARE @IDMainCompany int = 100;
DECLARE @Process_Date datetime = '2014-01-01';
declare @Query nvarchar(max);
SELECT
CAST(SR.IDMainCompany AS VARCHAR(12)) AS IDMainCompany

,CAST(SR.Salary AS VARCHAR(12)) AS Salary
,CAST(SR.Incentive AS VARCHAR(12)) AS Incentive

FROM SalaryReport SR
WHERE SR.IDMainCompany = @IDMainCompany
AND DATEPART(MM, SR.SalaryDate) = DATEPART(MM, @Process_Date)
group by IDMainCompany, DATEPART(MM, SalaryDate)
the sample data i posted is having less columns. actually i have 20 columns in the select list. Also the parameters to the where condition i gave two i.e IDMainCompany, SalaryDate. I will also need to use IDSubCompany for some case. My skeleton will be
Create Procedure Test(@IDMainCompany int, @IDSubCompany int = null, @SalaryDate datetime)
as
BEGIN
IF(@IDMainCompany is not null && @IDMainCompany > 0 && @SalaryDate is not null && @SalaryDate <> ' ' &&
@IDSubCompany is null)
BEGIN
--The logic what discussed on previous posts will falls here with @IDMainCompany, @SalaryDate as parameter to the where condition
END
IF(@IDMainCompany is not null && @IDMainCompany > 0 && @SalaryDate is not null && @SalaryDate <> ' ' &&
@IDSubCompany is null && @IDSubCompany > 0 )
BEGIN
--The logic what discussed on previous posts will falls here with @IDMainCompany, @SalaryDate,@IDSubCompany as parameter to the where condition
END
END
As said i need to include 20 columns in the select list and as union all used on the previous sample there are 20 columns on the first query and 20 columns on the second query after the union all. The SPC will become big. If i repeat this for second if condition,
it will be too big. How can i reduce this writing more lines.
I am aware of the concept dynamic sql. Is there any other way to do this? or if dynamic sql is the only option, can anyone help me rewriting this select statements as dynamic sql
Could anyone please assist me

thanks for your reply and yes, i am invoking this from my asp.net application using C# language. Would you like to share something?
<<
Yes,
You can use client side dynamic sql. I'm not talking about concatenating strings. I'm talking about using Runtime Text Tamplates (preprocesed templates in Visual Studio 2010).
Add a new "Runtime Text Template" item to your VS project. Be "MyReportTemplate.tt" the file name of the runtime text template. The content of this file should be something like the following:
<#@ template language="C#" #>
<#@ assembly name="System.Core" #>
SELECT
-- part of your query goes here
-- the interesting part come next
FROM
SalaryReport SR
WHERE
SR.IDMainCompany = @IDMainCompany
<# if (IDSubCompany.HasValue && IDSubCompany.Value > 0) { #>
AND SR.IDSubCompany = @IDSubCompany
<# } #>
AND
DATEPART(MM, SR.SalaryDate) = DATEPART(MM, @Process_Date)
GROUP BY
IDMainCompany, DATEPART(MM, SalaryDate)
Add a new c# code file named MyReportTemplate.partial.cs closed to MyReportTemplate.tt with the following code:
public partial class MyReportTemplate
public int? IDSubCompany { get; set; }
Then, to execute the query you can write a code similar to the following:
public DataTable ExecuteReport(int mainCompanyId, int? subCompanyId, DateTime processDate )
using (var cn = CreateConnection())
using (var cmd = new SqlCommand())
using (var adapter = new SqlDataAdapter(cmd))
cmd.Connection = cn;
var template = new MyReportTemplate
IDSubCompany = subCompanyId
cmd.CommandText = template.TransformText();
cmd.Parameters.AddWithValue("@IDSubCompany", subCompanyId == null ? (object) DBNull.Value : subCompanyId.Value);
cmd.Parameters.AddWithValue("@IDMainCompany", mainCompanyId);
cmd.Parameters.AddWithValue("@Process_Date", processDate);
var table = new DataTable();
adapter.Fill(table);
return table;

                 FROM table_a

                  AND col_a = p_var1);

END my_update;

Hi,
What you posted can probably be done without dynamic SQL. If the expression after LIKE does not conatin a wild-card, then LIKE behaves just like =. You can probably arrange things so that the query always uses LIKE.
If you need dynamic SQL, then use EXECUTE IMMEDIATE to perform it.
I think you want something like this:
PROCEDURE my_update
p_id            IN NUMBER,
p_var1          IN NUMBER,
my_value        IN VARCHAR2,
my_operator     IN VARCHAR2,
x_return_status OUT VARCHAR2,
x_errors        OUT VARCHAR2
) IS
l_dynamic_string VARCHAR2 (4000);
l_update_txt        VARCHAR2 (4000);
BEGIN
    l_dynamic_string := table_b.col2 || ' '     -- If my_operator is LIKE you'll need a space here
                                    || my_operator               /* value as: "=" OR "LIKE" */
                         || Q'< '>'
                         || my_value            /* VALUE AS "2233" OR "900%" */
                         || Q'<' >'
    l_update_txt := 'UPDATE table_b'
                || '   SET col1 = NULL'
              || ' WHERE id = p_id'
                || '   AND ' || l_dynamic_string
                || '   AND id = (SELECT table_a.id'
                 || '                     FROM table_a'
                 || '             WHERE id = p_id
                 || '               AND col_a = p_var1)';
    dbms_output.put_line (l_update_txt || ' = l_update_txt in my_update');
-- EXECUTE IMMEDIATE l_update_txt;
--     No EXCEPTION hider
END my_update;While writing dynamic SQL, it's a good idea to display the dynamic text. I used put_line to do that. Remember to comment out (or remove) the display code when testing is finished.
Notice that the EXECUTE IMMEDIATE command is commented out. Only after you've tested some, and you think l_update_txt is correct, should you un-commnet that line.
Never say "EXCEPTION WHEN OTHERS THEN NULL;"
Error messages help you, especially duting development when you're likely to have lots of coding errors.
If you really need to keep the program running after encountering certain errors, then it's okay to have an EXCEPTION block, but your use of either "WHEN OTHERS" or "THEN NULL" should be very limited, and you should not use both of them together.

Help to make this dynamic sql work

Hi,
I have many DDLs to execute and these DDLs change over time, so I try to load these DDLs into a table (y) and write a proc to loop through them. But I run into some problems and need your help.
Here are the details:
create table y ( x varchar2(4000));
CREATE TABLE error_log (
error_log_ID NUMBER(20),
statement VARCHAR2(2000),
error_msg VARCHAR2(400),
Action VARCHAR2(16)
CREATE SEQUENCE SEQ_error_log
START WITH 1
INCREMENT BY 1
NOMINVALUE
NOMAXVALUE
NOCYCLE
CACHE 20
NOORDER
CREATE OR REPLACE PROCEDURE CUST_UPDATE1 (
schema_name IN VARCHAR2 ,
table_tablespcae_name IN VARCHAR2,
index_tablespcae_name IN VARCHAR2
) AS
v_code NUMBER;
v_errm VARCHAR2(400);
sql_stmt1 VARCHAR2(3000) ;
CURSOR c1 IS SELECT x FROM y;
BEGIN
FOR i IN c1 LOOP
sql_stmt1 := i.x;
DBMS_OUTPUT.PUT_LINE ( 'x = '|| sql_stmt1 );
/ **************************** worked if use this hard coded ********************************
sql_stmt1 := 'CREATE TABLE '||schema_name||'.zz
aa VARCHAR2(4) NOT NULL,
bb VARCHAR2(100) NOT NULL,
cc VARCHAR2(2) NOT NULL
TABLESPACE '|| table_tablespcae_name;
BEGIN
EXECUTE IMMEDIATE sql_stmt1;
EXCEPTION
WHEN OTHERS THEN
v_code := SQLCODE;
v_errm := SUBSTR(SQLERRM, 1 , 400);
INSERT INTO error_log VALUES ( SEQ_error_log.nextval, sql_stmt1, v_errm, DECODE(v_code, -1430, 'IGNORE', 'CHECK') );
END;
END LOOP;
END;
Test:
exec cust_update1('SCOTT', 'USERS', 'c'); -- didn't use last parameter
Senario 1. insert into y values (
'CREATE TABLE schema_name.zz
aa VARCHAR2(4) NOT NULL,
bb VARCHAR2(100) NOT NULL,
cc VARCHAR2(2) NOT NULL
TABLESPACE table_tablespcae_name ' );
===> error_log show: ORA-01918: user 'SCHEMA_NAME' does not exist
Senario 2. insert into y values (
'''CREATE TABLE ''||schema_name||''.zz
aa VARCHAR2(4) NOT NULL,
bb VARCHAR2(100) NOT NULL,
cc VARCHAR2(2) NOT NULL
TABLESPACE ''|| table_tablespcae_name' );
==> error_log show: ORA-00900: invalid SQL statement
3. I hard coded the exact dynamic from step 2 and assigned to sql_stmt1, ( as commeted out in my code) it WORKED.
Thanks
George

hi,
do the scenario1 but you have to substitute the schema_name and table_space name with your actual string before calling the dynamic sql.
ei.
sql_stmt1 := replace(sql_stmt1,'schema_name',schema_name);
sql_stmt1 := replace(sql_stmt1,'table_tablespcae_name',table_tablespcae_name);
BEGIN
EXECUTE IMMEDIATE sql_stmt1;
EXCEPTION
WHEN OTHERS THEN
v_code := SQLCODE;
v_errm := SUBSTR(SQLERRM, 1 , 400);
INSERT INTO error_log VALUES ( SEQ_error_log.nextval, sql_stmt1, v_errm, DECODE(v_code, -1430, 'IGNORE', 'CHECK') );
END;
Cheers,
J

A little help writing an SQL please? May need some advanced functionality..

Hi All
I have arequirement to write an SQL that, given a total, and some rows from a table, can return the rows where one of the columns adds up to the total
These are transactions, so I'll boil it down to:
TranID, TranAmount
1, 100
2, 200
3, 250
4, 50
Suppose I will know that I need to seek 2 transactions totalling 300.
Possible combinations are ID 1+2, or 3+4. In this case, it is an error that I cannot find a single set of transactions that satisfies the number-of and the sum-of requirements
Suppose I will know that I need to seek 3 transactions totalling 550.
Only combination is ID 1+2+3
The difficulty for me here comes in that the number of transactions hunted will change, possibly without limits but as there will be a factorial element in terms of number of combinations, imposing an upper limit would be sensible.
I considered one solution within my understanding of SQL, that I can take my rows, and (supposing I enforce a limit of 3.. i.e. I cannot look for any more than a combination of 3 transactions) cross join them to themselves on condition that no tran ID is equal to any other tran ID, I will then get a huge block of cartesian joined transactions. I can then use a where clause to pick out row combinations having the correct sum. If I can use some kind of ID > otherID in my join, then I can make the cartesian a triangle shape which hopefully would prevent essentially duplicated rows of 1,2,3 and 1,3,2 and 3,2,1 and 3,1,2 etc
If I was only looking for 2 or 1 possible combinations, I would replace the tran amounts with 0 using a case when (because the number of times I'll cross join is fixed; I dont want to get into executing a dynamic sql)
Lastly I should point out that I'm doing this in PL/SQL or possibly Java so I have the ability to introduce custom logic if needs be
I would love to hear any other input from the wise and wizened members here as to how they might approach this problem.. Maybe oracle has some cool analytical functionality that I do not know of that will help here?
Thanks in advance guys n girls!

>
Now, as I'll be looking to update another columns on these transactions so that it can be picked up by an external process, can I modify this query so that it produces a list of TranIDs so I can say:
UPDATE tran SET falg='Y' WHERE tranID IN (<the query>)
>
Well if there's a workaround for the NOCYCLE, then the following will give all the transactions as rows for a particular total...

/Only use an EXCEPTION handler when you can improve on the default error handling. The default is to print an error message, so there's no point in you explicitly doing the same.
Why do you need dynamic SQL? Post the output results you want to get from the sample data you posted.
Given that you do need dynamic SQL, why can't you use bind variables, rather than including the values as literals?
Given that you have to use literals, use Q-notation for strings that include single-quote characters.
http://docs.oracle.com/cd/B28359_01/server.111/b28286/sql_elements003.htm#sthref337

Thanks for posting the CREATE TABLE and INSERT statements; that's very helpful.
Is that the best sample data for testing? Wouldn't it be better to have at least one row that was not the same as all the others?

What is l_t_seq? Post complete test scripts that people can run to re-create the problem and test their ideas.

Help with dynamic SQL

Hello,

Please advise,

Assuming the requirement is to find the partition in the supplied table with the supplied high value and the issue is that dba/all_tab_partitions.high_value is a long, one alternative along the same lines as you've done already is as follows. (I've just used a cursor rather than a function for simplicity of demo).

Dynamic SQL Help - Getting Errors

Basically I have a table with employee data, and I'm trying to create a dynamic PL / SQL block that creates a new table and copies over the data from employee table to the new one.
I'm teaching myself dynamic SQL so this is practice. Please don't offer "better solutions" because I'm sure there are plenty - I'm just looking to complete the code as is so I better understand this query language.
Here is my code:
set serveroutput on size 10000
declare
cursor c is
select table_name, tablespace_name
from user_tables where table_name = 'EMP';
cursor c2 is
select table_name, column_name, data_length, data_type, data_precision
from user_tab_cols where table_name = 'EMP';
cursor c3 is
select *
from emp;
counter number(3);
counter := 0;
begin
for i in c loop
if (counter = 0) then
create table emp2;
insert into emp2 table_name, tablespace_name;
for i in c2 loop
insert into emp2 table_name, column_name, data_length, data_type, data_precision;
counter := counter + 1;
end loop;
end loop;
for i in c3 loop
insert into emp2 empno, ename, job, mgr, hiredate, sal, comm, deptno;
end loop;
end;
Here are my errors:
Error starting at line 3 in command:
declare
cursor c is
select table_name, tablespace_name
from user_tables where table_name = 'EMP';
cursor c2 is
select table_name, column_name, data_length, data_type, data_precision
from user_tab_cols where table_name = 'EMP';
cursor c3 is
select *
from emp;
counter number(3);
counter := 0;
begin
for i in c loop
if (counter = 0) then
create table emp2;
insert into emp2 table_name, tablespace_name;
for i in c2 loop
insert into emp2 table_name, column_name, data_length, data_type, data_precision;
counter := counter + 1;
end loop;
end loop;
for i in c3 loop
insert into emp2 empno, ename, job, mgr, hiredate, sal, comm, deptno;
end loop;
end;

Pl Dynamic sql help needed

Hello Everyone
I am using database 11g. Can someone pl suggest what are the rules for putting single quotes for dynamic sql like
1) how many single quotes before/after a sql statement .
2) Rules for putting single quotes if there exists i) a variable in the sql statement
ii) a constant for e.g 100 in the sql statment.
If you could give the answers with a simple select statement, it will be even better !!!
Thanks and regards
Gautam

Help With SUBSTR in dynamic SQL statement

Following is the dynamic SQL statement.
EXECUTE IMMEDIATE 'UPDATE table_name pml
SET pml.'|| con_fields.field ||' = SUBSTR(pml.'||con_fields.field||' ||'' ''||
(SELECT pml1.'||con_fields.field||'
FROM table_name pml1
WHERE pml1.grp_id = '||los_concats.grp_id ||'
AND pml1.row_id = '||los_concats.row_id||'
AND pml1.loser_flg = ''Y''),1, '||con_fields.max_length||')
WHERE pml.grp_id = '||los_concats.grp_id ||'
AND pml.loser_flg IS NULL ';
what it does is that it updates a particular field. This field is concatenated by a field of a similar record.
My problem is with SUBSTR function. Since I am concatenating fields I do not want the field to be updated greater than max_length on that field, the reason why I use SUBSTR. the select query inside SUBSTR works alright with one of the AND condition in a WHERE clause not present. When I add that additional condition it gives me this error.
ORA-00907: missing right parenthesis.
Is there any way to get around this problem. Does SQL has other than SUBSTR function which can limit the character length.
Appreciate it.

The other alternative I thought about was to do this first
EXECUTE IMMEDIATE 'SELECT pml.'||con_fields.field||'
FROM table_name pml
WHERE pml.grp_id = '||los_concats.grp_id||'
AND pml.row_id = '||los_concats.row_id||'
AND pml.loser_flg = ''Y''
' INTO v_concat_field;
write into the variable v_concat_field and then use it into the previous script.
But on this I get SQL Command not properly terminated, I don't get it Why?
Donald I tried with your suggested script. It works fine with one of the conditions eliminated. I don't understand what the error trying to say?
Thanks
