Module Template.Dialect

Identification of SQL Dialects and Related Information

type t = ..

This type identifies the SQL dialect and other differences which may be relevant when composing query strings. This is an open type to allow future additions, either defined below or externally. Each case has the form of a constructor identifying the software which interprets the SQL code and its version number, if available, followed by any backend-specific details.
