Why not just use a giant 'REPLACE(NULL, 'Missing Value')' statement? It's more flexible and you don't have to worry about the syntax. *winks*

Hmm, I'm not sure. Maybe B? The syntax looks cleaner and more straightforward than the other options.

I'm going with C. The 'NullasNull *' syntax is correct, and 'Set NullValue = 'Missing Value'' is the right way to set the null values.

D looks good to me. The 'NullAsValue*' syntax ensures that null values are treated as a specific value, and 'Set NullValue = 'Missing Value'' sets that value to 'Missing Value'.
