Module: Sequel::SQL::OperatorBuilders
- Included in:
- Sequel, VirtualRow
- Defined in:
- lib/sequel/sql.rb
Overview
These methods are designed as replacements for the core extension operator methods, so that Sequel is still easy to use if the core extensions are not enabled.
The following methods are defined via metaprogramming: , -, *, /, &, |. The , -, *, and / operators return numeric expressions combining all the arguments with the appropriate operator, and the & and | operators return boolean expressions combining all of the arguments with either AND or OR.
