The error I am having is: "Error: Unable to open database file".
I have a connection -> cppdb::session
sql("sqlite3:db=/home/common/source/DB/Mdata.db");
I have a process that does a lot of selects, and updates, but always
after aproximatly 600 seconds i get this error, .... I also found that
this error occurs when i try to do an update (when i do stat.exec()).
my updates are like this (It works fine, on the first 600 seconds, and
then it gives an error):
//////////////////////////////////////////////
stat = sql << "update reading_h set read_id = ?, date = ?, time = ?
where read_id = ? and mrg_id = ?" << readId << date << time <<
headerReadId << mrgId;
stat.exec();
stat.reset();
stat.clear();
