Re: Multiple Statement result set problem with PreparedStatements ?

I have one but it relies on particular tables existing - if I get a few
minutes I too will simplify it to cause it ..

| What I'd expect to see is this sequence:
|
|   execute() returns false (no resultset for this result)
|   getUpdateCount() returns 1 (1 row inserted)
|   getMoreResults() returns false (no resultset for this result)
|   getUpdateCount() returns 1 (1 row inserted)
|   getMoreResults() returns true (resultset present)
|   getResultSet() returns an appropriate resultset for the SELECT
|   getMoreResults() returns false (no resultset for this result)
|   getUpdateCount() returns -1 (no more results)
|
| Your code seems to be expecting something different..
