> After [SQOOP-2737] several users ran into that their SQOOP commands are failing due to the fact the original commands were not phrased cases sensitive table/column/schema names in mind.
> There had been also another outcome of this feature, that the "--split-by" option does not accept Oracle functions anymore (e.g. MOD(col_name,4) ), as after correct escaping+quoting it would be handled by Oracle as a db col name, instead of an expression to evaluate.
> My goal here is to introduce an option to turn on/off the (fully proper and industry standard) escaping implemented in [SQOOP-2737], and also add an environment variable support for that, thus users would have the backward compatible fallback plan, and not changing their command.
> I do also plan to implement an argument for supporting split-by with database functions/expressions, and thus the escaping and the split-by expressions features would become independent.
