Issue Inserting Nested User Defined Types

[Ryan Whitfield]

I have a relatively complex data structure that I would like to store in a column, and I have made a number of nested user defined types, but I cannot figure out how to properly insert them.

For a more simple example I tried to insert rows with the following data structure:
parent {
name text,
nested frozen<nest>
}
frozen {
val1 int,
val2 int
}

My query looks like this:
INSERT INTO wt.test_table (key, val) VALUES (?,?)
When I try to bind the parent type to val, I get CASS_ERROR_LIB_INVALID_VALUE_TYPE. The query runs to completion, but val is null. Any guidance?

Thanks for bringing this to our attention. It's a bug in the driver. It'll be fixed in the next release. As a stop gap, you can use "varchar" instead of "text" (it's just an alias for "varchar") for string fields in UDTs.

I've created an issue to fix it: https://datastax-oss.atlassian.net/browse/CPP-287

Here's the fix: https://github.com/datastax/cpp-driver/commit/dc2955e3562d2bd99b218227e84523b96abcae22
