SELECT statement:
It is used to retrieve information from the table or
SELECT * FROM table_Name;
Expert Solution & Answer
Explanation of Solution
Difference between “WHERE” and “HAVING” clause:
| “WHERE” clause | “HAVING” clause |
| “WHERE” clause is used limit the number of rows. | “HAVING” clause is used limit groups. |
| “WHERE” clause cannot be used with aggregate functions. | “HAVING” clause in used to overcome “WHERE” clause because, “HAVING” clause uses aggregate functions. |
|
Syntax: SELECT column_Name(s) FROM table_Name WHERE condition; |
Syntax: SELECT column_Name(s) FROM table_Name GROUP BY column_Name HAVING condition; |
