Truncate time part from Datetime column or literal in Oracle SQL

I have shown how to truncate the time part from a datetime column value in SQL Server T-SQL in one of my previous posts here –

Here is the same (how to truncate the time part from a datetime column value) in Oracle SQL:

TRUNC(datetime_column)

or

TRUNC(datetime_expression)

very straight forward…!! isn’t it.. ? 🙂
