syntax for named streams

[justinmiller621]

Hey all,

I feel like there is probably a simple solution to this, but for the life of me, I cannot get the syntax right for using a named stream in my where clause. I've read the documentation over and over. Here is what I've got:

"select * from MyEvent as evt where MyUtils.myFunction(evt)"

When I create the statement, I get an error that reads:

"Property named 'evt' is not valid in any stream"

From everything I've read, this should be simple and my syntax is correct. Just for kicks, I also tried:

"select evt.* as myEvent from MyEvent as evt where MyUtils.myFunction(myEvent)"

And pretty much got the same error. The only way I've gotten this to work is, in the first statement, to replace 'evt' with 's0'. I'd like the stream name to be a little more descriptive than 's0' though.

Anyone have a clue what I'm doing wrong?

Thanks!
Justin

Has no one encountered this? Is this not as simple as I might have thought? Does my syntax look right?
