All Implemented Interfaces:

public class MonetConnection
extends MonetWrapper
implements Connection
A Connection suitable for the MonetDB database. This connection represents a connection (session) to a MonetDB database. SQL statements are executed and results are returned within the context of a connection. This Connection object holds a physical connection to the MonetDB database. A Connection object's database should able to provide information describing its tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, and so on. This information is obtained with the getMetaData method. Note: By default a Connection object is in auto-commit mode, which means that it automatically commits changes after executing each statement. If auto-commit mode has been disabled, the method commit must be called explicitly in order to commit changes; otherwise, database changes will not be saved.

  • Method Details

    • commit

      public void commit() throws SQLException
      Makes all changes made since the previous commit/rollback permanent and releases any database locks currently held by this Connection object. This method should be used only when auto-commit mode has been disabled.
      Specified by:
      commit in interface Connection
      Throws:
      SQLException - if a database access error occurs
      See Also:
      setAutoCommit(boolean)

    • rollback

      public void rollback() throws SQLException
      Undoes all changes made in the current transaction and releases any database locks currently held by this Connection object. This method should be used only when auto-commit mode has been disabled.
      Specified by:
      rollback in interface Connection
      Throws:
      SQLException - if a database access error occurs
      See Also:
      setAutoCommit(boolean)

    • close

      public void close() throws SQLException
      Releases this Connection object's database and JDBC resources immediately. All Statements created from this Connection will be closed when this method is called. Calling the method close on a Connection object that is already closed is a no-op.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Connection
      Throws:
      SQLException - if a database access error occurs

    • isClosed

      public boolean isClosed() throws SQLException
      Retrieves whether this Connection object has been closed. This method cannot be called to determine whether a connection to a database is valid or invalid. A typical client can determine that a connection is invalid by using the isValid() method.
      Specified by:
      isClosed in interface Connection
      Returns:
      true if this Connection object is closed; false if it is still open
      Throws:
      SQLException - if a database access error occurs

    • abort

      public void abort​(Executor executor) throws SQLException
      Terminates an open connection. The current implementation doesn't use the Executor argument, meaning it is identical to the close() method.
      Specified by:
      abort in interface Connection
      Parameters:
      executor - The Executor implementation which will be used by abort (not used)
      Throws:
      SQLException - if a database access error occurs or the executor is null

    • isValid

      public boolean isValid​(int timeout) throws SQLException
      Returns true if the connection has not been closed and is still valid. The driver will submit a query on the connection to verify the connection is still valid when this method is called. The timeout parameter is not currently used (executes as if it is equal to 0).
      Specified by:
      isValid in interface Connection
      Parameters:
      timeout - Not currently used. The time in seconds to wait for the database operation used to validate the connection to complete.
      Returns:
      true if the connection is valid, false otherwise
      Throws:
      SQLException - if the value supplied for timeout is less than 0

    • getWarnings

      public SQLWarning getWarnings() throws SQLException
      Retrieves the first warning reported by calls on this Connection object. If there is more than one warning, subsequent warnings will be chained to the first one and can be retrieved by calling the method SQLWarning.getNextWarning on the warning that was retrieved previously.
      Specified by:
      getWarnings in interface Connection
      Returns:
      the first SQLWarning object or null if there are none
      Throws:
      SQLException - if a database access error occurs or this method is called on a closed connection

    • clearWarnings

      public void clearWarnings() throws SQLException
      Clears all warnings reported for this Connection object. After a call to this method, the method getWarnings returns null until a new warning is reported for this Connection object.
      Specified by:
      clearWarnings in interface Connection
      Throws:
      SQLException - if a database access error occurs or this method is called on a closed connection

    • getDbNative

      protected ByteBuffer getDbNative()
      Retrieve the C pointer to the database. Used in ResultSet, Statement and PreparedStatement
      Returns:
      C pointer to the database

    • setAutoCommit

      public void setAutoCommit​(boolean autoCommit) throws SQLException
      Sets this connection's auto-commit mode to the given state. If a connection is in auto-commit mode, then all its SQL statements will be executed and committed as individual transactions. Otherwise, its SQL statements are grouped into transactions that are terminated by a call to either the method commit or the method rollback. By default, new connections are in auto-commit mode.
      Specified by:
      setAutoCommit in interface Connection
      Parameters:
      autoCommit - true to enable auto-commit mode; false to disable it
      Throws:
      SQLException - if a database access error occurs
      See Also:
      getAutoCommit()

    • getAutoCommit

      public boolean getAutoCommit() throws SQLException

      public void setReadOnly​(boolean readOnly) throws SQLException
      Puts this connection in read-only mode as a hint to the driver to enable database optimizations. MonetDB doesn't support read-only mode, hence an SQLWarning is generated if attempted to set to true here.
      Specified by:
      setReadOnly in interface Connection
      Parameters:
      readOnly - true attempts to turn on read-only mode; false disables it

      SQLException

    • setCatalog

      public void setCatalog​(String catalog) throws SQLException
      Sets the given catalog name in order to select a subspace of this Connection object's database in which to work. Because MonetDB does not support catalogs, the driver will silently ignore this request.

      Throws:
      SQLException

    • getCatalog

      public String getCatalog() throws SQLException
