Hi All. Does somebody know where (some internet sites or sample code) I can achieve a good understanding in the use of the status PQTRANS_IDLE, PQTRANS_ACTIVE, PQTRANS_INTRANS, PQTRANS_INERROR, PQTRANS_UNKNOWN using the lib function PQtransactionStatus? I need to use this flags in order to discipline some BEGIN-COMMIT blocks in a multithreading Windows/Linux environment. Each thread uses a separate db connection and shouldn't have any interaction with the other threads, but I still have messages as "WARNING: There is already a transaction in progress" and "WARNING: There is no transaction in progress". A further information is that the DB operation involved in each thread is a store in a table. This table is the same for each thread. Thanks in advance.
