I am just trying to make my stored procedure, where I have to initialized tons of variable to a empty string, shorter (fewer lines so that it would be easier to read). Do you see anything wrong with this SELECT of multiple variables?

Dmitry,

I believe your way is a very good way and this is what I use myself. If I can set them all at once, I do it.
