> In order to create a Sybase stored procedure that can be executed in a transaction (not autocommit), either:
> 1) the stored procedure needs to be created in a transaction
> or 2) the system stored procedure, sp_procxmode, has to be called (sp_procxmode <stored-proc-name> 'chained')
> SchemaExport executes DDL using autocommit, so Sybase stored procedures created with SchemaExport cannot be used in a transaction.
> It is not possible to run SchemaExport with autocommit=false. 
> This causes the unit tests for Sybase stored procedures to fail with a message like:
> "Stored procedure 'simpleScalar' may be run only in unchained transaction mode. The 'SET CHAINED OFF' command will cause the current session to use unchained transaction mode.'
> A workaround is to add a <database-object> tag containing the command to change the stored procedure to chained mode. This tag needs to follow the tag that defines the new stored procedure.
> For example, adding the following after the definition of paramHandling in the mapping for SybaseCustomSQLTest will change the paramHandling stored procedure so that it can be used in a transaction.
>    <database-object>
>         <create>
>         sp_procxmode paramHandling, 'chained'
>         </create>
>         <drop/>
>     </database-object>
