  1. 17000.00

  2. 17000*****

  3. **17000.00

  4. An error statement


Correct Option: D

AI Explanation

To answer this question, let's analyze the SQL statement step by step:

The SQL statement is as follows:

SELECT LPAD(salary, 10, *) FROM EMP WHERE EMP_ID = 1001;

The LPAD function in SQL is used to pad a string or number with a specific character to a specified length. In this case, the salary column is being padded with "*" characters to a length of 10.

The WHERE clause specifies that only the row where EMP_ID is equal to 1001 should be selected.

Given that the employee with EMP_ID 1001 has a salary of 17000, let's evaluate the statement:

SELECT LPAD(17000, 10, *) FROM EMP WHERE EMP_ID = 1001;

The LPAD function will pad the salary value of 17000 with "*" characters to a length of 10:

17000*****

Hence, the correct answer is D - An error statement. This is because the SQL statement is syntactically incorrect due to the use of an asterisk (*) as the padding character instead of a valid character or string.
