- Q6. Is it possible to use a package body without a package specification?
- Ans.
No, a package body cannot be used without a package specification.
A package body must always be associated with a package specification.
The package specification defines the public interface of the package, while the package body contains the implementation details.
Attempting to use a package body without a corresponding package specification will result in compilation errors.
- Q7. What is a SQL query that can be used to find duplicate values in a database?
- Ans.
Use a SQL query with GROUP BY and HAVING clause to find duplicate values in a database.
Use GROUP BY clause to group the values that are duplicated.
Use HAVING clause to filter out the groups that have more than one occurrence.
Example: SELECT column_name, COUNT(*) FROM table_name GROUP BY column_name HAVING COUNT(*) > 1;
- Q8. Queries using group by and having clause
- Ans.
Group by and having clause are used together to filter groups based on specified conditions.
Group by clause is used to group rows that have the same values into summary rows.
Having clause is used to filter groups based on specified conditions.
Example: SELECT department, AVG(salary) FROM employees GROUP BY department HAVING AVG(salary) > 5000;
- Q9. What are the definitions of the Substr and Instr functions?
- Ans.
Substr function extracts a substring from a string, while Instr function returns the position of a substring within a string.
Substr function syntax: SUBSTR(string, start_position, length)

Instr function syntax: INSTR(string, substring)
Example: INSTR('Hello World', 'World') will return 7
- Q10. What is the process for writing a SQL query that includes a subquery?
- Ans.
Writing a SQL query with a subquery involves nesting one query inside another to retrieve specific data.

Enclose the subquery within parentheses and use it in the WHERE or FROM clause of the main query
Ensure that the subquery returns a single value or a single column result
- Q11. What is the difference between char, varchar, and varchar2 data types?
- Ans.
Char is fixed length, varchar is variable length with max 4000 bytes, varchar2 is variable length with max 32767 bytes.
Char is fixed length and always right-padded with spaces, while varchar and varchar2 are variable length.
Varchar can store up to 4000 bytes of data, while varchar2 can store up to 32767 bytes.
Char is less efficient in terms of storage compared to varchar and varchar2.
