How to specify SQL escape character

Question

The percent (%) and underscore (_) character have special meaning in SQL,
and I want to escape these so users cannot type them in and effect the
queries. The database is DB2, which does not have a default escape
character, but one can be specified in an "escape" clause, like this:
select * from customer where name like 'ERIC\%' escape '\'
This query will look for a row where the name is literally equal to
'ERIC%'. This brings me to my question:
How do I specify to Kodo that it adds the "escape" clause to the end of
the SQL?
Thanks,

How do I specify to Kodo that it adds the "escape" clause to the end of
the SQL?Unfortunately there is no easy way to do this. The only way I can think of off
the top of my head is to create a subclass of the appropriate DBDictionary for
your database (see src/kodo/jdbc/sql/) and override the DBDictinoary's
toSelect(SQLBuffer, SQLBuffer...) method to add the escape clause. You can then
plug your custom dictionary into kodo:
kodo.jdbc.DBDictionary: your.custom.class.Name
