> Implement Statement.setQueryTimeout in the Client Driver
> --------------------------------------------------------

>          Key: DERBY-506
>          URL: http://issues.apache.org/jira/browse/DERBY-506
>      Project: Derby
>         Type: New Feature
>   Components: JDBC

> Currently, the Embedded Driver supports Statement.setQueryTimeout(), but the 
> Client Driver does not. The Client Driver should be enhanced and match the 
> Embedded Driver.
> For this, we need to transfer the timeout value from the client to the 
> server, preferably without a separate round-trip. I have some loose thoughts 
> on how to do this:
> * If the client has set a timeout value for a statement, prepend the (DRDA) 
> EXCSQLSTT command with an EXCSQLSET command which contains the timeout value; 
> conceptually a "SET STATEMENT TIMEOUT <seconds>" (this does not mean that we 
> need to extend the Derby grammar; only the Network Server needs to understand 
> this DRDA EXCSQLSET command).
> * In DRDAConnThread.parseEXCSQLSETobjects() on the server side, recognize the 
> "SET STATEMENT TIMEOUT" text, parse the timeout value and remember it for the 
> coming EXCSQLSTT command. Do NOT invoke executeUpdate() with the SET 
> statement [see note below].
> * In DRDAConnThread.parseEXCSQLSTT(), check if a timeout value has been set; 
> if so, use it (by setting the timeout value on the server-side Statement 
> object before calling execute/executeQuery).
