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,

Rather than using EXECUTE IMMEDIATE, try DBMS_SQL.PARSE.
The PARSE procedure also supports the following syntax for large SQL
statements:
DBMS_SQL.PARSE (
c IN INTEGER,
statement IN VARCHAR2S,
lb IN INTEGER,
ub IN INTEGER,
lfflg IN BOOLEAN,
language_flag IN INTEGER);
Note:
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) .
