Display values from table: The contents from the table can be viewed by using “SELECT” statement which comes under Data Manipulation Language (DML). The Syntax to view the contents using asterisk () is as follows: SELECT FROM table_Name; Selective columns can also be retrieved by replacing all the column(s) names in place of the asterisk symbol. WHERE Statement: “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. IS NULL operator: “IS NULL” operator is used to get values from the column(s) in which the condition is equal to “NULL”. Syntax: SELECT * FROM table_Name WHERE column_Name IS NULL;
