isValid(int timeout)

Syntax:

boolean isValid(int timeout) throws SQLException

Description:

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 operation.

Returns:

true if the connection is valid, false otherwise

Throws:

SQLException - if a database access error occurs or if timeout is less than 0
