is often used for cyclic operations, such as cycling through a set of values or assigning items to groups in a round-robin fashion.**Data Distribution:**It can be handy for evenly distributing data into a specified number of buckets or partitions.**Conditional Operations:**The`MOD()`

function is useful in creating conditional statements based on remainders, helping to categorize or filter data accordingly.

**Caution:** When using the `MOD()`

function, it’s essential to consider potential division by zero errors. Always ensure that the divisor is not zero before applying the `MOD()`

function in your queries.
