Enum SqlDialect

All Implemented Interfaces:
Serializable, Comparable<SqlDialect>
@PublicEvolving public enum SqlDialect extends Enum<SqlDialect>
Enumeration of valid SQL compatibility modes.

In most of the cases, the built-in compatibility mode should be sufficient. For some features, i.e. the "INSERT INTO T PARTITION(a='xxx') ..." grammar, you may need to switch to the Hive dialect if required.

We may introduce other SQL dialects in the future.

  • Enum Constant Details

    • DEFAULT

      public static final SqlDialect DEFAULT
      Flink's default SQL behavior.

    • HIVE

      public static final SqlDialect HIVE
      SQL dialect that allows some Apache Hive specific grammar.

      Note: We might never support all of the Hive grammar. See the documentation for supported features.
