  Key Concepts: 
  Column functions are a set of functions in SAP HANA that allow users to perform calculations on columns of data. These functions can be used to calculate aggregate values, such as sums, averages, and counts, as well as more complex calculations, such as standard deviation and correlation. 
  
  How to use it: 
  Column functions can be used in SQL statements to perform calculations on columns of data. For example, the SUM() function can be used to calculate the sum of a column of numbers. The AVG() function can be used to calculate the average of a column of numbers. The COUNT() function can be used to count the number of rows in a table. 
  
  Tips & Tricks: 
  When using column functions, it is important to remember that the order of the arguments matters. For example, when using the SUM() function, the column name should always come first and the table name should come second. Additionally, when using multiple column functions in a single statement, it is important to use parentheses to ensure that the calculations are performed in the correct order.
