Re: Linking two tables with Dates

I would suggest that the two answers you have previously received may be missing an important piece of the puzzle.

You can almost never write a WHERE clause like:

    WHERE date_field = date_value

The reason is that date field in Oracle do not just contain the date. They also contain the time. Try this instead:

    WHERE TRUNC(date_field) = TRUNC(date_value)
