    • createDialectHelper

      public static Dialect createDialectHelper(DialectFactory factory, DataSource dataSource)
      Creates a temporary connection and calls DialectFactory.createDialect(javax.sql.DataSource, java.sql.Connection).

      factory - Dialect factory
      dataSource - Data source, must not be null
      Returns:
      Dialect, or null if factory cannot create suitable dialect
