would you please help me to solve this on sql????

The columns dir and ctry contain values indicated as '-', and we need to
change these to Not Given while also capitalizing the first letter of each word
in the columns. Using the movies table, write a SELECT statement that meets
the following conditions:
a Show the column show_id;
b Create a CASE statementG
) WHEN the column dir is equal to, THEN output it as Not Given
) ELSE output using the INITCAP() function to the column di&
) Give the resulting column an alias AS director;
c Create another CASE statementG
) WHEN the column ctry is equal to, THEN output it as Not Given
) ELSE output using the INITCAP() function to the column ctr\
) Give the resulting column an alias AS country;
d Order the given result by the column show_id (in ascending order).
