How to retrieve column values into another tableview in iPhone? - iphone

Question

I am very beginner to IOS,I have deposit table and expense table in my database I want to retrieve only deposit amount from deposit table and expense amount from expense table into two tableviews means one is for deposit amount tableview and another one is for expense amount tableview in single screen. the below is my dbmodelclass.h in this
#import <UIKit/UIKit.h>
#import <sqlite3.h>
#interface dbModelClass : UIViewController
{
NSMutableDictionary *readDic;
NSMutableArray *readArray;
}
+(NSString *)connectDb;
+(BOOL)createTable;
+(BOOL)createTable3;
+(int)saveData:(NSMutableArray *)data;
+(int)saveData2:(NSMutableArray *)data;
+(NSMutableArray *)getData;
#end
this is my dbmodelclass.m

Please help me

Answer 1

There are several solutions to your question.
The best solution is actually the easiest.
Master viewController with two embedded tableViewControllers, each presenting and managing one table from your database.
During viewDidLoad, you will create an instance of each tableViewController, set it's frame to locate on the desired coordinates of your master view and add it to the master view.
Now you can have a clean and simple delegate model for each table and if you keep the instance of each tableViewController available within the master view controller (allocate as properties), you will be able to communicate to each table from the master view.
The more complicated way is to add two tableView to the master view xib, wire them both up to the datasource and delegate methods in the master viewController and then test each call to the delegate methods to determine which tableView called the method. I've done it but it's a pain to maintain in the long run.

Answer 2

You are not doing things good :).
Why you ar creating an object witch inherits from a UIViewController to manager the DataBase, you can just create an object that inherits from NSObject.
In the getData methode you are asking the data just for the deposit table, you should pass parameters ( table name and amount) to your methode to know if you want data from deposit table or expense2 table.
And finally in the NetViewController class you can do :
...
[dbModelClass connectDb];
NSArray *depositData = [dbModelClass getDataWith....]; // here you fetch your database with deposit table and others param
NSArray * expenseData = [dbModelClass getDataWith....]; // Here you fetch your database with expensive table and others param
Edited answer :
You can do like this for example :
-(NSMutableArray *)getDataForTable:(NSString *)tableName withAmount:(NSString *)amountName
{
sqlite3 *dbobj;
NSString *dbpath =[dbModelClass connectDb];
readArray=[[NSMutableArray alloc]init];
if(sqlite3_open([dbpath UTF8String], &dbobj)==SQLITE_OK)
{
sqlite3_stmt *statement=nil;
//**** NSString *string=#"SELECT name FROM emptable";
NSString *string = [NSString stringWithFormat:#"SELECT *FROM %# WHERE %#",tableName,amountName];
const char *query=[string UTF8String];
if(sqlite3_prepare_v2(dbobj, query, -1, &statement, NULL)==SQLITE_OK)
{
while (sqlite3_step(statement)==SQLITE_ROW)
{
readDic=[[NSMutableDictionary alloc] init];
[readDic setObject:[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)] forKey:#"deposit_amount"];
// NSString *aName=[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 0)];
// NSString *pwd=[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 1)];
//[readDic setObject:[NSString stringWithUTF8String:(char *)sqlite3_column_text(statement, 1)] forKey:#"remarks"];
// [readArray addObject:aName];
// [readArray1 addObject:pwd];
[readArray addObject:readDic];
// NSLog(#"%#",readDic);
}
}
sqlite3_finalize(statement);
}
Add this
-(NSMutableArray *)getDataForTable:(NSString *)tableName withAmount:(NSString *)amountName in the dbModelClass.h
and now you can call this methode in NetViewController by passing it the table name and the amount :
[dbModelClass connectDb];
NSArray * depositResult = [dbModelClass getDataWith:#"deposite" amountName:#"deposit_amount"];
// Do same thing for the other table by passing it the appropriate names.
PS : this code is not tested and you should refactor it, it's just to show you how to pass parameters for a methode
