It looks like there are some control characters in the code. A quick analysis showed that the character is char(63). So I did a Replace on char(63) and got good SQL that can be compiled.

Just paste the code into a query window, do a search and replace on single quotes replacing them with 2 single quotes. Then wrap that in a "Select Replace('', char(63), space(1))" query and execute it. I changed the output to text and increased teh output size to the maximum size.

The output will be good, usable code.
