ExecuteSQL doesn't select table if it having d

问题:

I have created table with single column having data type -dateTimeOffset value and inserted some values.

create table dto (dto datetimeoffset(7))
insert into dto values (GETDATE()) -- inserts date and time with 0 offset
insert into dto values (SYSDATETIMEOFFSET()) -- current date time and offset
insert into dto values ('20131114 08:54:00 +10:00') -- manual way

In Nifi,i have specified "Select * from dto" query in Execute SQL .

It shows below error..,

java.lang.IllegalArgumentException: createSchema: Unknown SQL type -155 cannot be converted to Avro type

If i change that column into dateTime then ExecuteSQL runs correctly but it doesn't worked in DateTimeOffset column.

Any help appreciated.

Many thanks

datetimeoffset is a MSSQL-specific JDBC type and is not supported by ExecuteSQL (which supports the standard JDBC types). You could try to cast the datetimeoffset field into some other standard type such as datetime, as described here.
