Database - Introduction to SQL - Discussion

The SQL aggregate functions SUM, AVG, MIN, and MAX are typically used with numeric columns, as they operate on numerical data to compute a sum, average, minimum, or maximum value, respectively. However, MIN and MAX can also be used with non-numeric data, such as strings, where they return the lexicographically smallest or largest value. So, MIN and MAX can not only be used with numeric columns. Therefore the final answer is FALSE.

SUM and AVG can be used only with numeric columns, for example int, small int, tinyint, decimal, numeric, float, real, money, and small money data types. MIN and MAX cannot be used with bit data types.

Avg and sum are needed to be numeric. While max, min and count can be non-numeric. i.e. they can be string as well.

You can use AVG(), SUM(), MIN(), MAX(), VARIANCE(), STDDEV() functions for numeric data types only. The COUNT() function can be used for any data type.

It is not working the sql server. So we can't say true for all. Ther will be the right ans for it is FALSE.
