Raj,

In the subject you mention database or file. If you've got files that contain the PL/SQL code, the following perl snippet might be of help to you:

$ perl -e '$prt=0; open F,"your_file_name" or die "cannot open file: $!\n"; while (<F>) { chomp;
/(?:select|insert|delete|update)\b[^;\/]*/igo && do { $prt = 1; }; ( $prt ) && print $_, "\n"; /^[^;\/]*[;\/]/ && do { $prt = 0; }; } close F; '

This will print all lines that have select/insert/update/delete statements in them, and any that follow up to and including the next line that contains a ';' or a '/'. It relies on the fact that all statements start with a defined keyword and end with a ';' or a '/'. There may be leading or trailing code snippets, depending on the formatting of the file. You can add any other keywords that you need to the (?:select|...) section, separated by a '|'.

Of course, this will only catch the pieces of dynamic sql that contain the starting keyword.

Hope this helps,
Tony
