Hello everyone, I'm just trying to grab one column of information and I
keep getting the exception thrown by this snippet of code in
coonection.cpp

if (lock()) {
if (throw_excptns) {
throw BadQuery("lock failed");
}
else {
return Result();
}
}

Here's what I do to get the error...

void GetEntryNumber(Connection* con){

Query entry_query = con->query();
entry_query << "select Entry_Number from db_environment";
Result EntryNumRow = entry_query.store(); <---THIS IS WHERE IT
ERRORS
Row Entry = EntryNumRow.fetch_row();


return;

}

My OS = Win XP Pro and im using the new SQL server 5.0.4-beta-max

Thanks!!

Lance

Just a guess... do you have other threads using mysql at the same time?

I just looked into Connections use of its locking facility a few days
ago, and it was my impression that it was only used to prevent multiple
simultaneous connection attempts. If I'm right, the only way for a lock
to continue to be asserted is if you aren't establishing a connection
correctly. Check the obvious things: can other MySQL programs connect
to that database using that user name and such, etc.
