Aggregate Functions:

SQL has some built-in functions and they are called as aggregate functions. SQL contains five built-in functions. They are:

  • SUM – This function is used to add values from the particular column.
    • Syntax: SELECT SUM(column_Name) FROM table_Name;
  • COUNT – This is used to count the number of rows for the particular column.
    • Syntax: SELECT COUNT(column_Name) FROM table_Name;
  • MAX – This function is used to get the maximum value from the column.
    • Syntax: SELECT MAX(column_Name) FROM table_Name;
  • MIN – This function is used to get the minimum value from the column.
    • Syntax: SELECT MIN(column_Name) FROM table_Name;
  • AVG – This function is used to get the average of all the values from the column.
    • Syntax: SELECT AVG(column_Name) FROM table_Name;
