Date Wed, 08 Mar 2006 21:25:39 GMT
Implement Connection.isValid as defined by JDBC4

         Key: DERBY-1090
         URL: http://issues.apache.org/jira/browse/DERBY-1090
     Project: Derby
        Type: Sub-task
  Components: JDBC  
    Reporter: Olav Sandstaa
    Priority: Minor
     Fix For:

The Javadoc for JDBC4 says this about Connection.isValid:

boolean isValid(int timeout) throws SQLException

Returns true if the connection has not been closed and is still valid. The driver shall submit
a query on the connection or use some other mechanism that positively verifies the connection
is still valid when this method is called. 

The query submitted by the driver to validate the connection shall be executed in the context
of the current transaction. 

Parameters: timeout - - The time in seconds to wait for the database operation used to validate
the connection to complete. If the timeout period expires before the operation completes,
this method returns false. A value of 0 indicates a timeout is not applied to the database

Returns: true if the connection is valid, false otherwise
