If the length – 50 is a negative value, then we have less than 50 characters to display and we can show the full summary column. Not bad, but if you have a lot of meta columns the most important column Text will get scrunched up and take up. If the length – 50 is null, then we have a null summary. The decode will check if the length of the SUMMARY column is greater than 50 by using the SIGN function. In the next example, we’ll use a decode to truncate the long text to the first 50 characters.

When dealing with long text entries in a report, sometimes it’s necessary to reduce or simplify the amount of data being displayed.
