I was investigating a sporadic failure in the test case aggregate/avg_mixed which does nothing but executes the below query and makes sure that an exception with the message "Unexpected type STRING in aggregation input stream. Expected type FLOAT. [AlgebricksException]" is thrown:
for $x in [float("2.0"), "hello world", 93847382783847382, date("2013-01-01")]
However, if you execute the query few times, sometimes it will return the error message as well as some results!!
The output looks something like this:
Unexpected type STRING in aggregation input stream. Expected type FLOAT. [AlgebricksException]
