Simon Charette 277ed07209 Fixed #29195 -- Fixed Exists.output_field resolution on single-valued queries. ... The Subquery class which Exists inherits from defaulted to using single-valued querie's field if no output_field was explicitly specified on initialization which was bypassing the Exists.output_field defined at the class level. Moving Subquery's dynamic output_field resolution to _resolve_output_field should make sure the fallback logic is only performed if required. Regression in 08654a99bb. Thanks Oli Warner for the detailed report.		2018-03-08 13:30:41 -05:00
