Hi all,

Could anybody help? Thanks!
How to execute a query in TMUDF? Don't know how to get current connection.

Another question is that "how many TMUDF instance it has in a query". Assume 
there is a query "select udr(a()) from xx", 100 rows in xx, that udf will be 
executed 100 times. How many instance of UDF class will be created?

Best Regards,
Kevin Xu
