Make the fixes and puts some other things I think is related and it would need. I also think that we would need an 'transformation' field to apply some transformation into a variable (or maybe the user would do that using 'select from dual' or binding another different variable just for that)
Note: we can take a look on the older revisions (like https://gist.github.com/luan-cestari/5a1d5a360b93cb4f38d2/8a0a25bd67d12c72058c9312a6f1ece85c7036ea ) to check some removed features (that may come back if we found an useful scenario)
The lastest version is in the following repository -> https://github.com/lightblue-platform/lightblue/tree/SQLFeatureBranch/lightblue-rdbms/metadata/src/main/resources/json-schema/metadata/rdbms/metadata

OK, I will wipe needsWhere and needsAnd from this schema.
OK about the conditional constructs. I thought sth, I will fix it during the morning
Not sure about having more then one schema. I think I got you idea, but I'm afraid that select schema would be necessary for insert/update/delete.
