AI Explanation

To answer this question, we need to understand the syntax of the TO_CHAR function in Oracle SQL.

The TO_CHAR function is used to convert a number or date value to a character string. It takes two parameters: the value to be converted and the format model.

In the given question, we need to display the number 2000 in the format "$2,000.00".

Now let's go through each option to determine which ones display the number in the correct format:

Option A) SELECT TO_CHAR(2000, '$#,###.##') FROM dual; This option uses the format model '$#,###.##'. However, it does not include the leading zeros after the dollar sign. Therefore, Option A is incorrect.

Option B) SELECT TO_CHAR(2000, '$0,000.00') FROM dual; This option uses the format model '$0,000.00', which includes the leading zeros after the dollar sign and displays the number 2000 in the format "$2,000.00". Therefore, Option B is correct.

Option C) SELECT TO_CHAR(2000, '$9,999.00') FROM dual; This option uses the format model '$9,999.00', which does not include the leading zeros after the dollar sign. However, it displays the number 2000 in the correct format "$2,000.00" by using a placeholder for the thousands digit. Therefore, Option C is correct.

Option D) SELECT TO_CHAR(2000, '$9,999.99') FROM dual; This option uses the format model '$9,999.99', which includes the leading zeros after the dollar sign. However, it displays the number 2000 with two decimal places instead of the required one decimal place. Therefore, Option D is incorrect.

Option E) SELECT TO_CHAR(2000, '$2,000.00') FROM dual; This option uses the format model '$2,000.00'. While it displays the number 2000 in the correct format "$2,000.00", it does not use the correct format model. Therefore, Option E is incorrect.

Option F) SELECT TO_CHAR(2000, '$N,NNN.NN') FROM dual; This option uses the format model '$N,NNN.NN'. However, it does not include the leading zeros after the dollar sign. Therefore, Option F is incorrect.

The three SELECT statements that display 2000 in the format "$2,000.00" are Options B, C, and D.
