Julian Hyde commented on CALCITE-1408:
--------------------------------------
+1 Looks good; I will commit right after 1.10.
It would be nice if there was a test that tries to access a column value
"SCOTT" by calling getLong(), and getLong() duly throws a SQLException. But I
don't know whether this test is possible in Avatica.
> ResultSet.getXxx methods should throw SQLException if cannot convert to the
> requested type

> {{AccessorImpl}} relies on {{cannotConvert(String)}} method to throw a
> exception when conversion is not possible between the accessor data type, and
> what the user requested.
> The exact class type of the exception is {{RuntimeException}} which is very
> generic, and not easy for the user to catch, unlike more specific types.
> Moreover JDBC drivers usually throws a {{SQLException}} instances for these
> kind of exceptions, which is likely what users are expecting.
