Simon Charette efa1908f66 Refs #25367 -- Moved Oracle Exists() handling to contextual methods. ... Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in the following cases. 1. When part of a SELECT clause. 2. When part of a ORDER BY clause. 3. When compared against another expression in the WHERE clause. This commit moves the systematic CASE WHEN wrapping of Exists.as_oracle to contextual .select_format, Lookup.as_oracle, and OrderBy.as_oracle methods in order to avoid unnecessary wrapping.		2019-08-13 06:48:14 +02:00
