  Key Concepts: 
  A scalar function is a type of function in SAP HANA that takes one or more input values and returns a single output value. It is used to perform calculations on data stored in the database. Examples of scalar functions include mathematical functions, string functions, date functions, and aggregate functions. 
  
  How to use it: 
  Scalar functions can be used in SQL statements to perform calculations on data stored in the database. For example, the SUM() function can be used to calculate the sum of a set of values. The syntax for using a scalar function is: SELECT () FROM . 
  
  Tips & Tricks: 
  When using scalar functions, it is important to remember that the output of the function will be a single value. Therefore, if you are trying to calculate multiple values, you will need to use multiple scalar functions. Additionally, it is important to ensure that the data types of the input and output values are compatible.
