Program Plan Intro

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;

DISTINCT Keyword: “DISTINCT” keyword is used to avoid redundant data (removing duplicate values) from a column. The syntax for “DISTINCT” keyword is as follows:

SELECT DISTINCT column_Name FROM table_Name;

WHERE clause:

“WHERE” statement is used limit the number of rows. For example: Consider a table “FTable” that has two columns named “FruitName” and “Color”. “WHERE” clause is used when there is a need to display the entire FruitName whose color is Red.

SELECT * FROM FTable WHERE color = 'red';

When the above statement is executed, red colored fruits get displayed.
