sqlite3_step always returns SQLITE_DONE - ios

Question

I'm trying to retrieve data from a single table sqlite database, but (sqlite3_step(statement) == SQLITE_ROW) is always returning false. I've manually checked the database for the values and they're present. Here's the full code:
-(NSArray *)findByPartNumber:(NSString *)partNumber
{
const char *dbpath = [databasePath UTF8String];
NSMutableArray *resultArray = [[NSMutableArray alloc] init];
if(sqlite3_open(dbpath, &database) == SQLITE_OK)
{
NSString *querySQL = [NSString stringWithFormat:#"SELECT Description, ListPrice FROM PriceList WHERE PartNumber=?"];
const char *query_stmt = [querySQL UTF8String];
if(sqlite3_prepare_v2(database, query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
sqlite3_bind_text(statement, 1, [partNumber UTF8String], -1, SQLITE_STATIC);
if(sqlite3_step(statement) == SQLITE_ROW)
{
NSString *description;
NSString *listPrice;
const char *tmp1 = (const char *)sqlite3_column_text(statement, 0);
const char *tmp2 = (const char *)sqlite3_column_text(statement, 1);
if(tmp1 == NULL)
description = nil;
else
{
description = [[NSString alloc] initWithUTF8String:tmp1];
[resultArray addObject:description];
}
if(tmp2 == NULL)
listPrice = nil;
else
{
listPrice = [[NSString alloc] initWithUTF8String:tmp2];
[resultArray addObject:listPrice];
}
sqlite3_finalize(statement);
}
}
sqlite3_close(database);
}
if([resultArray count] == 0)
return nil;
else
return resultArray;
}
The code enters the sqlite3_prepare_v2 block, but skips the sqlite3_step block. Am I missing something?

Answer 1

There is issue with your implementation.
You have written like:
sqlite3_bind_text(statement, 1, [partNumber UTF8String], -1, SQLITE_STATIC);
if(sqlite3_prepare_v2(database, query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
...
}
You can only bind values to prepared statements, so change the above code to:
if(sqlite3_prepare_v2(database, query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
sqlite3_bind_text(statement, 1, [partNumber UTF8String], -1, SQLITE_STATIC);
...
}

Turns out sqlite3_step was always returning SQLITE_DONE because there was no data. I had the databasePath set up incorrectly.
Incorrect code:
NSString *docsDir;
NSArray *dirPaths;
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = dirPaths[0];
databasePath = [[NSString alloc] initWithString:[docsDir stringByAppendingPathComponent: #"databaseName.sqlite"]];
Correct code:
databasePath = [[NSBundle mainBundle] pathForResource:#"databaseName" ofType:#"sqlite"];
