it should still fix some issue try this ...check db is whether it is opened or not and change this code...
code :
 -(void) update:(NSString *)filePath withName:(NSString *)place description:(NSString*)description
    {
        sqlite3* db = NULL;
        int rc=0;
        sqlite3_stmt* stmt =NULL;

        rc = sqlite3_open_v2([filePath cStringUsingEncoding:NSUTF8StringEncoding], &db, SQLITE_OPEN_READWRITE , NULL);
        if (SQLITE_OK != rc)
        {
            sqlite3_close(db);
            NSLog(@"Failed to open db connection");
        }
        else
        {
            /*
             NSString  *strMQueryupdate=[NSString stringWithFormat:@"update br set TOTAL='%@',QUTY='%@' WHERE PID='%@'",[@(total )stringValue],[@(lblQtn )stringValue],produdId];
             */

          NSString * query  = [NSString stringWithFormat:@"UPDATE  places SET description='%@' WHERE place='%@'",description,place];
            const char *sql = [query UTF8String];

            if (sqlite3_prepare_v2(db, sql, -1, & stmt, NULL) != SQLITE_OK)
            {
                NSLog(@"update fails");
            }
            else
            {
                sqlite3_bind_text(stmt, 1, [place UTF8String], -1, SQLITE_TRANSIENT);
                sqlite3_bind_text(stmt, 2, [description UTF8String], -1, SQLITE_TRANSIENT);

                int success = sqlite3_step(stmt);
                sqlite3_reset(stmt);
                if (success == SQLITE_ERROR)
                {

                }
                else
                {
                    NSLog(@"update success");

                }
                sqlite3_finalize(update_statement);
                sqlite3_close(db);
            }
    }

Hope this helps To update a value in my SQLite database (android) I use following method. The table is calles objects, the field I want to update is showinfo1, of a specific item with a certain id and level. , your query should be like this
code :
public void insertString(int id, int level, String field, String value){

    myDataBase.execSQL("UPDATE OBJECTS SET " + field + "='" + value + "' WHERE _ID=" + id + " AND LEVEL =" + level);

}

To fix the issue you can do I would like to know what is wrong with this code. I get the problem: error near "," syntax error , Your update query is the following.
code :
string updateQuery = string.Format(@"UPDATE ItemDatabase 
      SET _itemDescription=@ItemDescription, 
      _ItemPrice=@ItemPrice, 
      _ItemName=@ItemName 
      WHERE [_itemDescription] = '{0}', 
            [_itemPrice] = '{1}', 
            [_itemName] = '{2}'", Item.ItemDescription, Item.ItemPrice, Item.ItemName);
   SQLiteParameter[] sqlParams = new SQLiteParameter[]
   {
        new SQLiteParameter("@ItemDescription",DbType.String),
        new SQLiteParameter("@ItemPrice",DbType.String),
        new SQLiteParameter("@ItemName", DbType.String)
    }; 
      WHERE [_itemDescription] = '{0}' AND 
            [_itemPrice] = '{1}' AND 
            [_itemName] = '{2}'", Item.ItemDescription, Item.ItemPrice, Item.ItemName);
  Item.Description = "Item1";
  Item.ItemPrice = "100";
  Item.ItemName = "Stuff";
string updateQuery = @"UPDATE ItemDatabase 
      SET _itemDescription='Item1', 
      _ItemPrice='100', 
      _ItemName='Stuff' 
      WHERE [_itemDescription] = 'Item1' AND 
            [_itemPrice] = '100' AND 
            [_itemName] = 'Stuff'");

I think the issue was by ths following , This is the first time I came around UPDATE statement in SQLITE. Base on what I found, I came up with this method that, well, does not work) The statement itself works fine, I have checked it. And values of result and SQLITE_OK equals to 0 for some reason. So, where did it went wrong? Thank you. , Issue is with this portion of code:
code :
if (result == SQLITE_OK){
        NSLog(@"archiveArticle: Article was archived!");
        return true;
    }else{
        NSLog(@"archiveArticle: Error while creating update statement. %s", sqlite3_errmsg(self.db));
        return false;
    }
sqlite3_exec(self.db, "COMMIT", NULL, NULL, &errmsg);

  SQLiteDatabase db = this.getWritableDatabase(); 
  ContentValues contentValues = new ContentValues(); 
  contentValues.put(COLUMN_CHECKBOX, Str1 ); 
  String selection = ResturantEntry.COLUMN_LOCATION + " =? ";

  String[] selectionArgs = new String[]{chkboxValue};
 //count denotes the number of rows update
