1. I'm trying to minimize the number of requests I'm doing to the DB. What
I need is a way to count the number of rows that the query return to me
prior to going thru the "sqlite3_step()".
If this number is 0, I want to skip the processing and just return.
How is this different from just calling sqlite3_step, seeing it return
SQLITE_DONE right away, and getting out of the loop?
//////// check the number of rows returned by the query
if( numRows == 0 )
return;
else
{
sqlite3_step( stmt );
sqlite3_finalize( stmt );
}
This leaks a statement handle. Make it
if (sqlite_step(stmt) == SQLITE_ROW) {
// Process the row
}
sqlite3_finalize( stmt );
Is there such a function?
No there is not.
2. Considering the same code above, if I want to delete this row, I will
need another statement variable. But will it screw up the original select
statement? Something like this:
Just run this statement;
DELETE FROM players WHERE players.isnew="1";
You are making it way too complicated.
