As Frediano said, there is some slight performance gain in reducing
network traffic.  Any efficiency gains, though, are usually overwhelmed
by two things:

1.  Query execution time
2.  Program complexity  

I would suggest you reduce #2 to the extent possible.  If it's more
convenient to call  dbsqlexec() once with several statements, do so,
else don't.  :-)  Just remember to exhaust the results with a loop until
dbresults() returns NO_MORE_RESULTS.
