New Features

  • An :auto_increment key has been added to the schema information for primary key columns on JDBC, PostgreSQL, MySQL, MSSQL, DB2, and SQLite. This fixes issues in the schema_dumper extension where non-auto-incrementing integer primary keys are no longer dumped as auto-incrementing.

    For adapters that don't have specific support for detecting auto incrementing primary keys, Sequel now assumes a primary key is auto incrementing only if it is not a composite primary key and the type contains int (e.g. int, integer, bigint).

Other Improvements

  • Dataset#empty? now ignores any order on the dataset. Previously, calling empty? on a dataset ordered by an alias in the SELECT list could raise an exception.

  • Schema qualified tables are now handled correctly in many_through_many associations.

  • Using a hash as the value for the :eager association option now works correctly.

  • All PG::ConnectionBad exceptions are now treated as disconnect errors in the postgres adapter. This should be more robust than the previous method of trying to recognize disconnect errors by trying to parse the exception message.

  • Sequel now skips a hash allocation when issuing queries through datasets if sharding is not used.

  • Sequel no longer uses the JDBC schema parsing in the jdbc/sqlserver adapter. Instead, it uses the MSSQL schema parsing, which should be more accurate than the generic JDBC schema parsing.
