01:55 Conclusion and Summary
Today, we are discussing IIF function. IFF Function perform actions based on conditions, like the 'IF' function in Excel, which uses conditional logic to print different values depending on whether a condition is true or false.
The syntax for an 'IF' function is simple: write 'IF', the column name, an equality check, and the specified value. For example, you can print '1' where 'PRD1' is, and '2' where 'PRD2' is. This can be nested for more conditions.
Using functions in the industry is common, but they can get lengthy and error-prone, especially with bracket placement. Finding errors is easier as they show the line number.
An alternative to the 'IF' function is the 'CASE' statement, which is simpler and will be covered in the next video. Thank you for watching Educate Cube. Please like, share, and subscribe to our YouTube channel, and follow us on LinkedIn.
