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.
