Expand description

Types and functions related to PG’s and Sqlite’s ON CONFLICT clause

Upsert is currently supported by diesel for the following database systems:

PostgreSQL version 9.5 or newer
Sqlite3 version 3.24.0 or newer
MySQL version 5.7 or newer

See the methods on InsertStatement for usage examples.

Constructing an upsert statement from an existing select statement requires a where clause on sqlite due to a ambiguity in their parser. See the corresponding documentation for details.
