[jira] [Comment Edited] (CASSGO-118) Nil map for UDT column inserts zero-valued UDT instead of NULL
[ https://issues.apache.org/jira/browse/CASSGO-118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18071719#comment-18071719 ]

I'm actually unsure if we should change this, as it has been there for a long time, and applications could rely on this behaviour. Probably fixing it in the next major release is what we should do

> Key: CASSGO-118
> URL: https://issues.apache.org/jira/browse/CASSGO-118
> Project: Apache Cassandra Go driver
> Issue Type: Bug
> Reporter: Bohdan Siryk
> Priority: Normal
>
> Inserting a row with a nil map for a UDT-typed column results in a non-NULL value whose fields behave like defaults / zero values, instead of storing NULL for the whole UDT.
> *Expected*
> The UDT column is NULL in DB.
> *Actual*
> The UDT column is present (not NULL) and fields appear as type defaults (empty string, 0, false, etc.).
