Is there a good way to have a dialect automatically add casting to 'THEN' expressions in 'CASE' statements?
I'm working on a dialect for the H2 database, via Jython. H2 requires values in a 'THEN' expression to have explicit casts (see: Unknown data type thrown with a case statement where all values are parameters in preparedStatement<http://h2-database.66688.n3.nabble.com/Unknown-data-type-thrown-with-a-case-statement-where-all-values-are-parameters-in-preparedStatement-td3091039.html> ) I would like to make it so that my H2 dialect will automatically add casting to 'CASE' expressions, so that users of the dialect don't have to use literal_columns each time they want to use a 'CASE' expression. One idea I had was to add a 'before_execute' event that checks elements to see if their case statements, but that seems a bit kludgy. is there a better way? Levity: Q: What do a database developer and a hollywood producer have in common? A: They both can have problems with casting. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
