The DB driver I am working with (for a sybase DB) does not implement a Connection.isValid(). What is the most efficient way I can validate a db connection using a query (or otherwise) in Java?

Libraries such as C3P0 and DBCP allow you to provide a validation query which is typically something very simple such as “select 1”. Hence, you could take the same approach or simply use either of these libraries (my recommendation would be C3P0).
However, rather than testing the connection prior to executing your query you could simply attempt to execute and then retry the operation if it fails because the connection is invalid. Alternatively you could consider a non-pooled connection approach where the connection is created on-the-fly each time (e.g. such as Spring’s
DriverManagerDataSource).
