Enum Class JdbcMetadataOnBoot

java.lang.Object
java.lang.Enum<JdbcMetadataOnBoot>
org.hibernate.engine.jdbc.env.JdbcMetadataOnBoot
All Implemented Interfaces:
Serializable, Comparable<JdbcMetadataOnBoot>, Constable
public enum JdbcMetadataOnBoot extends Enum<JdbcMetadataOnBoot>
Whether access to JDBC metadata is allowed during bootstrap. Typically, Hibernate accesses this metadata to understand the capabilities of the underlying database to help minimize needed configuration.

API Note:
The default value is ALLOW.

  • Enum Constant Details

    • DISALLOW

      public static final JdbcMetadataOnBoot DISALLOW
      Access to the JDBC metadata is disallowed. At a bare minimum, this requires specifying the dialect or database being used. Specifying the database version is recommended as well.
      API Note:
      The specified Dialect may also provide defaults into the "explicit" settings.

    • ALLOW

      public static final JdbcMetadataOnBoot ALLOW
      Access to the JDBC metadata is allowed.
      API Note:
      This is the default.
      Implementation Note:
      When errors occur accessing the JDBC metadata, implicit values will be used as needed.

    • REQUIRE

      public static final JdbcMetadataOnBoot REQUIRE
      Access to the JDBC metadata is required.
      Implementation Note:
      Functions like ALLOW, except that errors which occur when accessing the JDBC metadata will be propagated back to the application.
