    Hi Haifeng,

    There is a limit on the size of the output column as directed by its datatype in vertica. So if it is a varchar column the limit would be 65000. But in your UDF that doesn't seem to be the case. When you specified outtype = 'any' , you would have implemented the outtypecallback function. Please check that in the outtypecallback function you set the length of the output column appropriately.

    Thanks
