You can create a small procedure where you output multiple 100 char lines. Just break the string up into 100 char chunks and display each chunk separately.

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<http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sql.htm#i997676>.

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) .
