Hi, I've created a patch for the ability to handle multi statement
queries that return multiple result sets. I'm attaching that, as well
as multiquery.cpp, which is intended to go in the examples directory.
This is helpful in the case where the user wishes to execute multiple
statements in one query, and then iterate through the result sets, as
seen in the c api documentation at:
Mysql seems to treat a call to a stored procedure that returns a result
set, even if it is just one, as a multi-statement query. If you are
calling such a stored procedure, you should use these methods to make
sure you clean up properly after the call. The multiquery.cpp
illustrates this, as well as other multi-statement types of calls.
I also modified the copy method of the ResUse class to make sure that a
ResUse object gets properly purged if an un-initialized ResUse object-
one with a null result_- gets assigned to it.
