unsuccessful queries and lost connection

unsuccessful queries and lost connection

Hi all,

I'm programming a piece of software that continuously looks up if it has
pending sql queries (UPDATE and INSERT) and executes them.
I should also control if I lost the db connection or if a sql query was
unsuccessful.

My question is:

in what circumstances could I lose the connection to the db and how would I
realize it?

I have found in the refman a mysqlpp::BadQuery class.

Just something like this?

try {
   mysqlpp::Query sqlQuery = sqlConn.query();
   sqlQuery << q;
} catch(mysqlpp::BadQuery ex) {

}

Is there a better way to deal with errors?

I only want to know if it occurred an error, I am not interested in other
stats or results.



Thanks in advance,
Albert
