INNER JOIN Database
This Demo Used To Save Data in Different Table and also Get This Data of Database
1) Open the Build Phases tab, and within Link Binary with Libraries, add the following frameworks:
-libsqlite3.dylib
2) create Sqlite3 Object In your view .h file for using like that ..
#import <sqlite3.h>
3) Create Database :
in Database create Two Table And Take empid as a Common to Get Data
table 1 is Look Like This :
table 2 is Look Like This :
 In "viewcontroller.m" File we create database first and also find the path using "NSSearchpathfordocumentdirectory" method . In "viewdidload" method put This code.THIS IS COPY TO VIEWCONTROLLER.M (VIEWDIDLOAD METHOD) :
NSString *docsDir;
NSArray *dirPaths ;
dirPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES); // Get the documents directory
docsDir = dirPaths[0];
databasePath = [[NSString alloc]initWithString: [docsDir stringByAppendingPathComponent:@"data.sqlite"]]; // Build the path to the database file
This code is useful for the copy file NSBundle to the NSDocument directory folder. But First Check the file is available in bundle or not ..?
THIS IS COPY TO APPDELEGATE.M :-
NSString *pathsToReources = [[NSBundle mainBundle] resourcePath];
NSString *yourOriginalDatabasePath = [pathsToReources stringByAppendingPathComponent:@"data.sqlite"];
NSArray *pathsToDocuments = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [pathsToDocuments objectAtIndex: 0];
NSString *dbPath = [documentsDirectory stringByAppendingPathComponent:@"data.sqlite"];
if (![[NSFileManager defaultManager] isReadableFileAtPath: dbPath]) {
if ([[NSFileManager defaultManager] copyItemAtPath: yourOriginalDatabasePath toPath: dbPath error: NULL] != YES)
NSAssert2(0, @"Fail to copy database from %@ to %@", yourOriginalDatabasePath, dbPath);
}
4) Make Your Storyboard Like This :
5) Write Coding Which Is given Below :
