    • Constructor Detail

      • PyConnection

        public PyConnection​(java.sql.Connection connection)
                     throws java.sql.SQLException
        Create a PyConnection with the open connection.
        Parameters:
        connection -
        Throws:
        java.sql.SQLException
    • Method Detail

      • toString

        public java.lang.String toString()
        Produces a string representation of the object.
        Overrides:
        toString in class PyObject
        Returns:
        string representation of the object.
      • classDictInit

        public static void classDictInit​(PyObject dict)
        Method classDictInit
        Parameters:
        dict -
      • __findattr_ex__

        public PyObject __findattr_ex__​(java.lang.String name)
        Finds the attribute.
        Overrides:
        __findattr_ex__ in class PyObject
        Parameters:
        name - the name of the attribute of interest
        Returns:
        the value for the attribute of the specified name
      • close

        public void close()
        Close the connection now (rather than whenever __del__ is called). The connection will be unusable from this point forward; an Error (or subclass) exception will be raised if any operation is attempted with the connection. The same applies to all cursor objects trying to use the connection.
      • commit

        public void commit()
        Commit any pending transaction to the database. Note that if the database supports an auto-commit feature, this must be initially off. An interface method may be provided to turn it back on.

        Database modules that do not support transactions should implement this method with void functionality.

      • rollback

        public void rollback()
        This method is optional since not all databases provide transaction support.

        In case a database does provide transactions this method causes the database to roll back to the start of any pending transaction. Closing a connection without committing the changes first will cause an implicit rollback to be performed.

      • nativesql

        public PyObject nativesql​(PyObject nativeSQL)
        Converts the given SQL statement into the system's native SQL grammar. A driver may convert the JDBC sql grammar into its system's native SQL grammar prior to sending it; this method returns the native form of the statement that the driver would have sent.
        Parameters:
        nativeSQL -
        Returns:
        the native form of this statement
      • cursor

        public PyCursor cursor()
        Return a new Cursor Object using the connection. If the database does not provide a direct cursor concept, the module will have to emulate cursors using other means to the extent needed by this specification.
        Returns:
        a new cursor using this connection
      • cursor

        public PyCursor cursor​(boolean dynamicFetch)
        Return a new Cursor Object using the connection. If the database does not provide a direct cursor concept, the module will have to emulate cursors using other means to the extent needed by this specification.
        Parameters:
        dynamicFetch - if true, dynamically iterate the result
        Returns:
        a new cursor using this connection
      • cursor

        public PyCursor cursor​(boolean dynamicFetch,
                               PyObject rsType,
                               PyObject rsConcur)
        Return a new Cursor Object using the connection. If the database does not provide a direct cursor concept, the module will have to emulate cursors using other means to the extent needed by this specification.
        Parameters:
        dynamicFetch - if true, dynamically iterate the result
        rsType - the type of the underlying ResultSet
        rsConcur - the concurrency of the underlying ResultSet
        Returns:
        a new cursor using this connection
      • __enter__

        public PyObject __enter__()
