    • getDriverFor

      String getDriverFor(String connectionUrl)
      Returns the fully qualified class name of the JDBC driver to use for given connection URL or null if this dialect doesn't know how to handle that URL.
      Parameters:
      connectionUrl - the JDBC URL of the database to connect to
      Returns:
      the FQCN of the driver on null.

    • canWorkWith

      boolean canWorkWith(DatabaseMetaData metaData) throws SQLException
      Returns true if this dialect can handle a connection to a database identified by the provided metadata, false otherwise.

      Note that this method is only used when Sqlg is provided the connection from JNDI and thus the connection and pooling is handled externally.

      Parameters:
      metaData - the metadata identifying the database being connected to.
      Returns:
      true if this dialect can work on this connection, false otherwise
      Throws:
      SQLException

    • instantiateDialect

      SqlDialect instantiateDialect()
      Instantiates the dialect based on the provided configuration. This only gets called if getDriverFor(String) returns non-null class name or canWorkWith(DatabaseMetaData) returns true.
      Returns:
      the dialect to use, never null

    • load

      static SqlgPlugin load(String connectionUrl)
      Loads the plugin to use for the provided JDBC URL.
      Parameters:
      connectionUrl - the JDBC URL of the database to connect to
      Returns:
      the plugin to use, never null
      Throws:
      IllegalStateException - if no suitable Sqlg plugin could be found

    • load

      static SqlgPlugin load(DatabaseMetaData metaData) throws SQLException

      Throws:
      IllegalStateException - if no suitable Sqlg plugin could be found
