sqlite3_prepare_v2(contactDB, query_stmt, -1, &statement1, NULL);
while (sqlite3_step(statement1) == SQLITE_ROW)
{
NSLog(#"Enter in the denger zone");
NSString *idField = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement1, 0)];
NSString *addressField = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement1, 2)];
NSString *NameField = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement1, 1)];
NSString *phoneFiels = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement1, 3)];
NSLog(#"ID is=%#",idField);
NSLog(#"Name is=%#",NameField);
NSLog(#"Address is=%#",addressField);
NSLog(#"Phone No. is=%#",phoneFiels);
[idField release];
[NameField release];
[phoneFiels release];
[addressField release];
}
sqlite3_finalize(statement1);
sqlite3_close(contactDB);
}
thanks in advance.

We are sharing Some come which is using NSMutableDictionary to store your data and you can easily use that code to print your data,where do you want
if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK)
{
const char *sql = "Select * from CalculateTime";
sqlite3_stmt *insertStmt;
if(sqlite3_prepare_v2(database, sql, -1, &insertStmt, NULL) != SQLITE_OK)
NSAssert1(0,#"Error: Failed to prepare statement with message '%s'.",sqlite3_errmsg(database));
arrayCountry = nil;
arrayCountry = [[NSMutableArray alloc]init];
arrayCity = nil;
arrayCity = [[NSMutableArray alloc]init];
arrayFlag = nil;
arrayFlag = [[NSMutableArray alloc]init];
arrayZone = nil;
arrayZone = [[NSMutableArray alloc]init];
NSString *str2;
while(sqlite3_step(insertStmt)==SQLITE_ROW)
{
char *row;
row = (char*)sqlite3_column_text(insertStmt, 0);
if(row != NULL)
{
str2 = [NSString stringWithUTF8String:row];
[arrayCountry addObject:str2];
}
row = (char*)sqlite3_column_text(insertStmt, 1);
if(row != NULL)
{
str2 = [NSString stringWithUTF8String:row];
[arrayCity addObject:str2];
}
row = (char*)sqlite3_column_text(insertStmt, 2);
if(row != NULL)
{
str2 = [NSString stringWithUTF8String:row];
[arrayFlag addObject:str2];
}
row = (char*)sqlite3_column_text(insertStmt, 3);
if(row != NULL)
{
str2 = [NSString stringWithUTF8String:row];
[arrayZone addObject:str2];
}
}
}
Access these dictionary data to print anywhere..
