sqlite3_finalize(stmt);
}
plz suggest me something or if this is not possible then tell me how can i add 2 different array in table at same time

Answer 1

Your _twoArray contains two object which are in turn NSArray. Now it is fixed that you will have always two array within one array, then try this
NSArray *nameArr = [_twoArray objectAtIndex:0];
NSArray *bdArr = [_twoArray objectAtIndex:1];
if (sqlite3_open([databaseFilePath UTF8String], &database1) == SQLITE_OK)
{
for (int i = 0; i< [nameArr count]; i++)
{
sqlite3_stmt *stmt;
int x;
char *update = "insert into PersonNamesAndBirthDates (Names,Birthdates) values(? ?);";
x = sqlite3_prepare_v2(database1, update, -1, &stmt, nil);
if (x == SQLITE_OK)
{
NSLog(#"PersonName is -->%#",[NSString stringWithFormat:#"%#",[nameArr objectAtIndex:i]]);
NSLog(#"BirthDates is -->%#",[NSString stringWithFormat:#"%#",[bdArr objectAtIndex:i]]);
sqlite3_bind_text(stmt, 1, [[NSString stringWithFormat:#"%#",[nameArr objectAtIndex:i]] UTF8String],-1, NULL);
sqlite3_bind_text(stmt, 2, [[NSString stringWithFormat:#"%#",[bdArr objectAtIndex:i]] UTF8String],-1, NULL);
}
if (sqlite3_step(stmt) != SQLITE_DONE){}
NSLog(#"Error: ");
sqlite3_finalize(stmt);
}
sqlite3_close(database1);
}

Your array contain two objects which are array type.
for (int i=0;i<[[_twoArray objectAtIndex:0] count];i++)
{
sqlite3_stmt *stmt;
int x;
char *update = "insert into PersonNamesAndBirthDates (Names,Birthdates) values(? ?);";
x = sqlite3_prepare_v2(database1, update, -1, &stmt, nil);
if (x == SQLITE_OK)
{
NSLog(#"PersonName:%# BirthDate:%#",[[NSString stringWithFormat:#"%#",[[_twoArray objectAtIndex:0] objectAtIndex:i]],[[NSString stringWithFormat:#"%#",[[_twoArray objectAtIndex:1] objectAtIndex:i]]);
sqlite3_bind_text(stmt, 1, [[NSString stringWithFormat:#"%#",[[_twoArray objectAtIndex:0] objectAtIndex:i]] UTF8String],-1, NULL);
sqlite3_bind_text(stmt, 2, NULL,-1, NULL);
}
if (sqlite3_step(stmt) != SQLITE_DONE){}
NSLog(#"Error: ");
sqlite3_finalize(stmt);
}

You can't do it in the way you are trying to, as your for loop is providing you a array at a time not the variables. You can use following two ways:
create two arrays name and dob and add records respectively on same index then use for loop for the index of any array and use 2 string variable to store data of same index and then use these to create query
Or you can create a NSDictionary in which you can store, name and dob, such as
NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:0];
while (records) {
NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:
#"Mr. X", #"name"
#"13/12/82", #"dob"
nil];
[array addObject:dictionary];
records--;
}
And then create each query for index. to retrieve dictionary, values and to create query you use following code,
for (NSDictionary *dict in array) {
NSString *userName = [dict valueForKey:#"name"];
NSString *dateOfBirth = [dict valueForKey:#"dob"];
//write query here
}
