The param set by command COM_STMT_SEND_LONG_DATA is not cleared using COM_STMT_RESET

[x4studio]

According to mysql protocol, prepare statment's param set by command COM_STMT_SEND_LONG_DATA will not be cleared until command COM_STMT_RESET is called. If one param is long enough to use send long data in one Exec and then very short in next Exec, it may cause error. Is it right?

Looks like you are right.

For reference: http://dev.mysql.com/doc/internals/en/com-stmt-reset.html

Has anyone ever encountered a problem with this?
From the documentation it is not clear to me if it must be reset. Moreover I can not find any other driver actually using this packet type.
