how to insert NSDate in sqlite? - iphone

Question

HELLO i am trying to insert Current date in my database table
i have a column dateVisited of type datetime
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"yyyy/MM/dd HH:mm:ss"]; //this is the sqlite's format
NSDate *stringTime = [NSDate date];
NSString *formattedDateStringTime = [formatter stringFromDate:stringTime];
sqlStr = [NSString stringWithFormat:#"Insert into AnwaltHistory (id,dateVisited) values (%d,'%#')",Id formattedDateStringTime];
NSLog(#"%#",sqlStr);
BOOL Res = [appDelegate InsUpdateDelData: sqlStr];
if (Res)
{
NSLog(#"The Following instrunction is excuted successfully !");
}
else
{
NSLog(#"The Following instrunction Failed to execute !");
}
the statement executes successfully but when i actually go and check the table it says invalid date... i dont know why
as i have printed sqlstr i copy paste from the console and paste it in sqlite and run it manually it runs perfectly fine and has the actual date....
can any one guide me where i am mistaken :S.......
please

Answer 1

Why not use:
"Insert into AnwaltHistory (id,dateVisited) values (%d,datetime())",Id

Answer 2

You could try this:
double dateVisited = [[NSDate date] timeIntervalSince1970]; //now
// save dateVisited to your 'dateVisited' field

Answer 3

According to the official documents, the DateTime on SQLITE should be in ISO8601 format (AKA: a string of ("YYYY-MM-DD HH:MM:SS.SSS"))
Therefore, to store the date, you should format your date string, below is a code to help you with this:
NSDate *SourceDate = [NSDate date]; // Or whatever NSDATE you like...
NSDateFormatter *MyDateFormatter = [[NSDateFormatter alloc] init];
[MyDateFormatter setDateFormat:#"yyyy-MM-dd HH:mm:ss.SSS"];
NSString *SQLiteQuery = [NSString stringWithFormat:#"Insert into YourTable(YourDateField) values ('%#')", [MyDateFormatter stringFromDate:SourceDate]];
This should do it, give's a shout if you need more help,
