SQL database

1. Write a SELECT statement that returns four columns based on the TotRev column of the Course table: Use the CAST function to return the first column as data type decimal with 2 digits to the right of the decimal point. Use CAST to return the second column as a varchar. Use the CONVERT function to return the third column as the same data type as the first column. Use CONVERT to return the fourth column as a varchar, using style 1.
