Answer 1

nothing wrong with your code just do one thing return dataArray will be outside of the loop , you will load all quotes like this, accept my answer thanks
-(NSMutableArray *)getAllQuotesData
{
NSMutableArray *quotesArray = [[NSMutableArray alloc] init];
NSString *sqlStr = [NSString stringWithFormat:#"SELECT quote FROM quotes"];
sqlite3_stmt *ReturnStatement = (sqlite3_stmt *) [self getStatement:sqlStr];
while (sqlite3_step(ReturnStatement)==SQLITE_ROW)
{
#try
{
QuotesDC *myQuote = [[QuotesDC alloc] init];
NSString *user_id = [NSString stringWithUTF8String:(char
*)sqlite3_column_text(ReturnStatement,0)];
NSString *category = [NSString stringWithUTF8String:(char *)sqlite3_column_text(ReturnStatement,1)];
NSString *subcategory = [NSString stringWithUTF8String:(char *)sqlite3_column_text(ReturnStatement,2)];
NSString *quote = [NSString stringWithUTF8String:(char *)sqlite3_column_text(ReturnStatement,0)];
NSString *star = [NSString stringWithUTF8String:(char *)sqlite3_column_text(ReturnStatement,4)];
myQuote.userid = [user_id integerValue];
myQuote.category = category;
myQuote.subcategory = subcategory;
myQuote.quote = quote;
myQuote.star = star;
[quotesArray addObject:myQuote];
NSLog(#"%u", quotesArray.count);
}
#catch (NSException *ept) {
NSLog(#"Exception in %s, Reason: %#", __PRETTY_FUNCTION__, [ept reason]);
}
}
return quotesArray;
}

Replace your query string with this
NSString *sqlStr = [NSString stringWithFormat:#"SELECT * FROM quotes WHERE quote=320"];

Use this code,this may help you
-(void)retrivequoteFromDB
{
NSMutableArray * quoteArray=[[NSMutableArray alloc]init];
sqlite3 *sqliteDB;
sqlite3_stmt *compiledStatement = NULL;
if(sqlite3_open([databasePath UTF8String], &sqliteDB)==SQLITE_OK)
{
NSString *sql=#"SELECT quote FROM quotes";
const char *sqlC=[sql UTF8String];
if(sqlite3_prepare(sqliteDB, sqlC, -1, &compiledStatement, NULL)==SQLITE_OK)
{
while(sqlite3_step(compiledStatement) == SQLITE_ROW)
{
NSString *quote = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)];
[quoteArray addObject:quote];
}
}
sqlite3_reset(compiledStatement);
}
sqlite3_finalize(compiledStatement);
}

try like this once check your data base table 320 records placed or not if present then it'l gives ll the data.
SELECT quote FROM quotes //it'l gives only quote columnvalues from quotes table.
if you want to get all the data then use asterisk '*' symbol in the place of quote.
otherwise try like this,
SELECT quote FROM quotes limit 320 //it'l gives top 320 records
once read this one you'l found the problem. select Query
