A,D,E Correct answer
Explanation

All three options (A, D, E) correctly format 1890.55 as $1,890.55. The format codes use G for group separator (thousands) and D for decimal separator. Option A uses 'G000D00' with fixed-width digits. Option D uses '99G999D00' allowing up to 5 digits. Option E uses '99G999D99' which also works for the given value. Option B is incorrect because V99 is used for scaling, not formatting. Option C uses '99,999' which doesn't match standard Oracle format model syntax.

AI explanation

To display the value 1890.55 as $1,890.55 using SQL, you can use the TO_CHAR function to format the number as a string with the desired format. Let's analyze each option:

Option A) SELECT TO_CHAR(1890.55,'$0G000D00') This option is correct because it uses the TO_CHAR function with the format mask '$0G000D00'. The '$' symbol represents the currency symbol, 'G' represents the thousands separator, and 'D' represents the decimal separator. The '0' ensures that leading zeros are displayed.

Option B) SELECT TO_CHAR(1890.55,'$9,999V99') This option is incorrect because the 'V' symbol is not a valid format character in SQL. It should be 'D' to represent the decimal separator.

Option C) SELECT TO_CHAR(1890.55,'$99,999D99') This option is incorrect because it uses the format mask '\$99,999D99', which would display the value as \$001,890.55. The '99,999' format does not account for the number of digits before the decimal separator.

Option D) SELECT TO_CHAR(1890.55,'\$99G999D00') This option is correct because it uses the format mask '\$99G999D00'. The 'G' symbol represents the thousands separator, 'D' represents the decimal separator, and '0' ensures that leading zeros are displayed.

Option E) SELECT TO_CHAR(1890.55,'\$99G999D99') This option is correct because it uses the format mask '\$99G999D99'. The 'G' symbol represents the thousands separator, 'D' represents the decimal separator, and '99' allows for two decimal places.

The correct answers are A, D, and E, as these options use the correct format masks to display the value as $1,890.55.
