Sometimes you need to manipulate a transfer data from a souce database
to another; if you need to exclude some columns from the table list (you got them as comma delimited string list dinamically) you have to cast the string column name as sysname type
you can do it with this function, but you can use for whatever table type you want to retrieve
Just pass a list as string comma separated and receive a table of that list.
Adjust the return type at your convinience.
