Pl/sql Procedure is Not Creating With the CLOB data Type

Question

Hi,
I am Using Oracle 10g Express Edition Release2.... My Doubt is While creating a table With CLOB Data Type the table is created successfully,but while Creating a Procedure With the CLOB Data type i am getting an Error Message
2667/5 PL/SQL: Statement ignored
2667/24 PLS-00382: expression is of wrong type
then i tried With the Varchar2(30000) the Procedure is Created Successfully note i have not changed any thing in my code except the data type.
I am Just Confused ......Why the Procedure is not Created with CLOB Data type?
Please advice ...
Thank U

Answer 1

hi,
Thanks for reply....Another Example
CREATE TABLE USER_MAS (USER_ID     VARCHAR2 (20 Byte),MAIL_ID     VARCHAR2 (255 Byte));
set serveroutput on
declare
atable varchar2(64) := 'USER_MAS';
acolumn varchar2(64) := 'MAIL_ID';
avalue varchar2(64) := 'NEWYORK' ;
dyn_sql clob;
begin
dyn_sql := 'update '||atable||' set '||acolumn||' = '''||avalue|| '''' ;
dbms_output.put_line(dyn_sql);
execute immediate dyn_sql;
end;
commit ;
Error at line 2
ORA-06550: line 9, column 23:
PLS-00382: expression is of wrong type
ORA-06550: line 9, column 5:
PL/SQL: Statement ignored
When i Changed the Data type to varchar2(64)
update USER_MAS set MAIL_ID = 'NEWYORK'
PL/SQL procedure successfully completed.
Commit complete.
I like to Know the Reason Why the Procedure is Not Created in Oracle 10g XE DB
Note :the Same Script i used in 11g DB the Procedure is Created Successfully....
Why you need use CLOB or VARCHAR2 in your temp_num variable as you sending parameters as number?
In the Procedure we are create some run time queries while executing the procedure. There are around 10 run time queries created.
The size of each query is more than 4000 characters . We then add all the queries using union all after each query  to the clob variable as the normal varchar will not support.
Please Advice
