I've implemented a Concrete inheritance model and Oracle 11g is balking on `CAST(NULL AS CLOB) as fieldn` during the pjoin union query execution with:
ORA-00932: inconsistent datatypes: expected - got CLOB This happens when the unioned tables representing the 2 subclasses have different `Text` fields which are created as CLOBs on Oracle. This is independent of cxOracle version, since we get the same problem running the emitted query in native Oracle SQL Developer: `select cast(null as clob) from dual` ORA-00932: inconsistent datatypes: expected - got CLOB 00932. 00000 - "inconsistent datatypes: expected %s got %s" *Cause: *Action: Error at Line: 1 Column: 8 The rest of the CASTs of NULL work fine, though, but generally NULL columns should have no datatype in Oracle via NULL definition. I am on SQLAlchemy 1.1.3. Does 1.2x handle this better? If yes, and I need to hotpatch, which lines would I need to patch? -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
