Answer 1

- (void)CreateDatabase
{
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentPath = [paths objectAtIndex:0];
NSString *finalPath = [documentPath stringByAppendingPathComponent:#"CabManagement.sqlite"];
success = [fileManager fileExistsAtPath:finalPath];
if(success)
{
NSLog(#"Database Already Created.");
return;
}
NSString *defaultPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"CabManagement.sqlite"];
success = [fileManager copyItemAtPath:defaultPath toPath:finalPath error:&error];
if(success)
{
NSLog(#"Database Created Successfully.");
}
}
- (void)InitializeDatabase
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentPath = [paths objectAtIndex:0];
NSString *finalPath = [documentPath stringByAppendingPathComponent:#"CabManagement.sqlite"];
if(sqlite3_open([finalPath UTF8String], &dbCabManagement) != SQLITE_OK)
{
sqlite3_close(dbCabManagement);
NSLog(#"Error to Open Database :- %s",sqlite3_errmsg(dbCabManagement));
}
}

Creating database programmatically
NSArray *dirPath= NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = dirPath[0];
NSString *databasePath = [[NSString alloc]initWithString:[docDir stringByAppendingPathComponent:#"YourDBName.db"]];
NSLog(#"the DB path:%#",databasePath);
NSFileManager *fileMgr =[NSFileManager defaultManager];
if ([fileMgr fileExistsAtPath:databasePath] == NO)
{
const char *dbPath = [databasePath UTF8String];
if (sqlite3_open(dbPath, &mydatabase) == SQLITE_OK)
{
char *errMsg;
const char *sql_stmt ="CREATE TABLE IF NOT EXISTS YourTableName (ID INTEGER PRIMARY KEY AUTOINCREMENT,Name Text,Age Text,Image Text,Location Text,Date Text,Time Text,MilliSecondsTime Text,Address Text)";
NSString *Status;
if (sqlite3_exec(mydatabase, sql_stmt, NULL, NULL, &errMsg))
{
Status =#"Failed to Create Table";
}
else
{
Status =#"Suucess in Create Table";
}
NSLog(#"%#",Status);
sqlite3_close(mydatabase);
}
else
{
Status =#"Failed to Open/Create Database";
NSLog(#"%#",Status);
}
}

Generally , I would like to use FMDB by ccgus to manage my database and there is no need for me to care about How to save the database.
NSString *path = [[NSBundle mainBundle] pathForResource:#"demo" ofType:#"db"];
FMDatabase *demoDB = [[FMDatabase alloc] initWithPath:path];
if(demoDB.open == NO) {
//Something is wrong when open the "demo.db" database
} else {
//Open the database success.Then you kan run some sql query in the database.
}
