JDBC receiver adapter - sqlBindMode

Hi,

I need to perform Delete all existing records from a table (statement1) and Insert the new set of records into the same table (statement2). And in order to improve the performance, I've tried to use sqlBindMode in the JDBC receiver adapter. But, sqlBindMode is throwing the below error for delete statement.  Is it because the delete statement missing the where clause? Any idea how this can be fixed?

(structure 'Statement_Delete'): java.lang.NullPointerException: while trying to invoke the method java.util.ArrayList.size() of an object loaded from local variable 'whereArray'

Thanks
