Thank you all for the hints.

Is there any way, I can output and see if the syntax is correct ? 

DBMS_OUT doesn't seems to work.

Thank You,

Kind Regards,

The PARSE procedure also supports the following syntax for large SQL 
   c                  IN   INTEGER, 
   statement          IN   VARCHAR2S, 
   lb                 IN   INTEGER, 
   ub                 IN   INTEGER, 
   lfflg              IN   BOOLEAN, 

   language_flag      IN   INTEGER); 

The procedure concatenates elements of a PL/SQL table statement and parses 
the resulting string. You can use this procedure to parse a statement that 
is longer than the limit for a single VARCHAR2 variable by splitting up 
the statement. 

VARCHAR2S is a table of VARCHAR2

See the PL/SQL Packages and Types book.

Hi List, 

We have a requirement in generating triggers for a set of configured 
tables in our database ( Oracle 10g) . I am thinking to write a procedure 
which reads the table names configured  and create trigger for each table 
with a defined business ( Its just for audit , so the trigger code is same 
for table A and B but the name and columns might differ , the basic logic 
is same.) 

The problem I am facing is that , in  my generic procedure  I am not able 
to generate the trigger string and execute it using 'EXECUTE IMMEDIATE' as 
for some of our tables when all columns and trigger code is appended the 
string goes beyond 4000( defined as VARCHAR2) .
