FMDB and index 0 beyond bounds for empty array - ios

Question

I am going crazy trying to debug this. I am trying to basically duplicate a row in my SQLite db and increment a value. I have used similar insert statements elsewhere in my code and had no problems, but this time it is not cooperating. The program errors when it gets to the executeUpdate statement.
I am relatively new to iOS programming and have gone as far as I can on my own.
Here is my function:
+ (BOOL)updatePetWithNewVet:(NSNumber *)i {
NSString *appSupportDir = [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) lastObject];
NSString *dbPath = [appSupportDir stringByAppendingPathComponent:#"pets.sqlite"];
FMDatabase *database = [FMDatabase databaseWithPath:dbPath];
[database open];
FMResultSet *results = [database executeQuery:#"Select * from vets order by vetID desc limit 1"];
if ([results next]) {
NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
NSInteger vID = [results intForColumn:#"vetID"];
NSInteger vID2 = vID+1;
NSNumber *newVetID = [NSNumber numberWithInteger:vID2];
NSString *vName = [results stringForColumn:#"vetName"];
NSString *vPhone = [results stringForColumn:#"vetPhone"];
NSString *vStreet = [results stringForColumn:#"vetStreet"];
NSString *vCity = [results stringForColumn:#"vetCity"];
NSString *vState = [results stringForColumn:#"vetState"];
NSNumber *vZipcode = [f numberFromString:[results stringForColumn:#"vetZipcode"]];
NSLog(#"%#", vName);
NSLog(#"%#", vPhone);
NSLog(#"%#", vStreet);
NSLog(#"%#", vCity);
NSLog(#"%#", vState);
NSLog(#"%#", vZipcode);
NSLog(#"VET ID: %ld", (long)vID);
NSLog(#"NEW VET ID: %#", newVetID);
[results close];
[database executeUpdateWithFormat:#"INSERT INTO vets (vetID, vetName, vetPhone, vetStreet, vetCity, vetState, vetZipcode) Values (?, ?, ?, ?, ?, ?, ?)", newVetID, vName, vPhone, vStreet, vCity, vState, vZipcode, nil];
NSLog(#"%#", [database lastErrorMessage]);
}
[database close];
return 1;
}
And it is not working. This is what get when I crash:

Answer 1

You are using executeUpdateWithFormat, but are not using printf-style syntax in your SQL. Either use executeUpdateWithFormat with printf-style format string, or use executeUpdate with the ? placeholders.
Personally, I'd suggest you just use executeUpdate (and drop the nil from the end of the list).
