iOS sqlite3 and datetime

[newdev]

How do I read a datetime field back from the database?

Also, I have a database table where I insert a row with a datatime column .. now i want to read this back.. how can i do that? any idea?

You have to parse it yourself. One weakness of sqlite3 is that it doesn't have a native understanding of datetime even though it provides the column type. The best way to handle this situation is to store an int representing the date and manipulate it yourself.

I agree, and NSDate's dateWithTimeIntervalSince1970: and timeIntervalSince1970 methods are your friends

what if

but what if I am dealing with dates prior to 1970 ?

if i am aksed to insert a data in precreated table whose schema i am not allowed to change, what would be my approach ? i tried sqlite3_bind_text(addstmt, 1, "28-DEC-1947", -1, SQLITE_TRANSIENT)

I get error "SQL logic error or missing database"

thanks and regards

index 1

i figured out, this statement is not a problem, this returns SQLITE_OK

in fact in sqlite3 field indexes start from 1 not zero
