Nope, sorry. Still full of HTML stuff. Hang on, I'll see if I can fix it.
Luca's message below:
=====================
I'm using for the first time the postgres lock utilities, but brobably
I'm doing something of not legal.
My action are:
void *Execute(void *pParam)
{
........................................
........................................
& nbsp; string tableLock = "BEGIN WORK;";
tableLock.append(" LOCK TABLE ");
tableLock.append(actorTable);
tableLock.append(" IN ACCESS EXCLUSIVE MODE;");
res = PQexec(connection, tableLock.c_str());
........................................
........................................
pObj->ReturnNotification(static_cast<string>(notify->relname),connection);
.........................................
.........................................
CleanUpBeforeStop(void *pParam);
}
void CleanUpBeforeStop(void *pParam)
{
.........................................
.........................................
res = PQexec(pPti->conn, "COMMIT WORK;");
}
Well, the function Execute is the detached procedure of a thread. In
here I execute the LOCK command on the table "actorTable". Then, in the
method ReturnNotification I read the locked table. At last, calling the
function CleanUpBeforeStop, I execute the COMMIT command.
Well, all this doesn't work (the connection is th e always the same in
all methods and functions). Have I to Lock the table, perform some
operation on this table, and unlock the table all in the same function
scope?
Any Idea?
Thanks in advance.
