Question

I am trying to fill up an NSmutableAray with data from sqlite database.

ItemShow class:

@interface ItemShow : NSObject 
{
NSInteger itemID;
NSString *itemYear;
NSInteger rarity;
NSString *mintage;
NSInteger availability;
NSInteger quality;
NSString *mintMark;
NSString *masterMark;
NSString *dateCode;
NSString *dateDescription;
}

Getters/setters are ok

Method in DBAccess class:

-(NSMutableArray*)getItemsOverView:(int)itemID
{
NSMutableArray *itemsArray=[[[NSMutableArray alloc]init]autorelease];
const char *sqlItems=sqlite3_mprintf("SELECT itm.itemID,itm.itemYear,itm.rarity,itm.mintage,iaval.availability as avalibility,iaval.quality as quality,itm.Mintmark,itm.masterMark,dc.dateCode,dc.dateDescription\
                                     from items as itm\
                                     join itemAvailability as iaval on iaval.itemID=itm.itemID\
                                     join dateCultures as dc ON dc.dateCultureID=itm.dateCulture\
                                     WHERE itm.itemID=%i",itemID);
sqlite3_stmt *statement;
int sqlResult = sqlite3_prepare_v2(database, sqlItems, -1, &statement, NULL);
if ( sqlResult== SQLITE_OK)
{
    while (sqlite3_step(statement) == SQLITE_ROW)
    {
        ItemShow *itemShow=[[ItemShow alloc]init];
        itemShow.itemID=sqlite3_column_int(statement, 0);
        char *itemYear=(char *)sqlite3_column_text(statement, 1);
        itemShow.rarity=sqlite3_column_int(statement, 2);
        char *mintage=(char *)sqlite3_column_text(statement, 3);
        itemShow.availability=sqlite3_column_int(statement, 4);
        itemShow.quality=sqlite3_column_int(statement, 5);
        char *mintMark=(char *)sqlite3_column_text(statement, 6);
        char *masterMark=(char *)sqlite3_column_text(statement, 7);
        char *dateCode=(char *)sqlite3_column_text(statement, 8);
        char *dateDescription=(char *)sqlite3_column_text(statement, 9);

        itemShow.itemYear=(itemYear)?[NSString stringWithUTF8String:itemYear]:@"";
        itemShow.mintMark=(mintMark)?[NSString stringWithUTF8String:mintMark]:@"";
        itemShow.masterMark=(masterMark)?[NSString stringWithUTF8String:masterMark]:@"";
        itemShow.mintage=(mintage)?[NSString stringWithUTF8String:mintage]:@"Unknown";
        itemShow.dateCode=(dateCode)?[NSString stringWithUTF8String:dateCode]:@"";
        itemShow.dateCode=(dateDescription)?[NSString stringWithUTF8String:dateDescription]:@"";

        [itemsArray addObject:itemShow];
        [itemShow release];

    }
    sqlite3_finalize(statement);
}
else
{
    [self dbConnectionError];
}

return itemsArray;
}

code in ViewDidLoad

DBAccess *dbAccess=[[DBAccess alloc]init];
self.dataArr=[dbAccess getItemsOverView:itemID];
   // ItemShow *itmShow=[dataArr objectAtIndex:1];
NSLog(@"%d",[dataArr count]); //returns 1. So, empty array
[dbAccess closeDataBase];
[dbAccess release];

Same construction works fine in other views, but now it gives error – empty array out of bounds.

What was checked

1. Select works. checked it in SQLiteStudio
2. itemID is int and the view getting it correct from previous view like it gets title.

Answer 1

Have resolved it by myself. Just made new method. Now it works
