Hi

Hi,

I am trying to create a function that gets passed a statement as a string
and then I need to change the table_name within the string by adding a
"_cdc" to it, then execute the statement

ex:

string passed could be GRANT all ON authors TO bob.

then

EXECUTE GRANT all ON authors_cdc TO bob

I'm looking into parsing the string but i can't find a way to parse in a
way that'll work. Any ideas?

The extension Orafce https://github.com/orafce/orafce has some basic
library for parsing SQL PLVlex.

Another solution can be using regular expressions
