hi all,
i've been banging my head against the keyboard, trying to figure out what is
going on. i am writing a program in xcode that uses the c/c++ sqlite3
library. the problem i am having is the following:
1. i open a connection to my db using sqlite3_open()
NSString *dbFile = [[NSBundle mainBundle]
pathForResource:@"data"
ofType:@"db"];
if (sqlite3_open([dbFile UTF8String], &db) == SQLITE_OK) {
//NSLog(@"SQLite connection open SUCCEEDED!");
} else {
//NSLog(@"SQLite connection open FAILED!");
}
2. i run a sqlite3_exec function call to either insert,delete or update
NSString query = @"delete from table where id =3";
char *error;
int rc = sqlite3_exec(db, [query UTF8String], NULL, NULL, &error);
if (rc == SQLITE_OK) {
//debug start
NSLog(@"DBObject.update. SQLITE_OK");
//debug end
return YES;
} else {
//debug start
NSLog(@"Error: %@", [NSString stringWithUTF8String:error]);
sqlite3_free(error);
//debug end
return NO;
}
3. the return value from sqlite3_exec is SQLITE_OK. however, when i check
the database table nothing has changed. (select sql statements work fine.)
4. when i type in the insert, delete or update sql statement into the
console it works fine.
i don't know what is going on. can anyone please help? thanks so much!!
