I have the following select statement to get the last login from the user table. This works very well under SQLite, now I'm porting the database and have Compact Edition from Microsoft.
SELECT LOGIN
FROM USERS
WHERE LASTLOGIN = (SELECT MAX(LASTLOGIN) FROM USERS)
The lastlogin
column is datetime
.
This doesn't seems to work, what's wrong? The subselect? Or something about the comparing of datetime?
this makes only one table lookup and not 2 from your previous statement
SELECT top 1 LOGIN FROM USERS
order by LASTLOGIN desc
