Hey @samuelcolvin, if I get it right, your first option looks like [union_extract from DuckDB.](https://duckdb.org/docs/sql/functions/union.html#union_extractunion-tag) [Example usage](https://shell.duckdb.org/#queries=v0,CREATE-TABLE-tbl1-(u-UNION(num-INTEGER%2C-str-VARCHAR))~%0AINSERT-INTO-tbl1-values-(1)%2C-('two')%2C-(union_value(str-%3A%3D-'three'))~,SELECT-union_extract(u%2C-'str')-AS-str%0AFROM-tbl1~) I'm trying to implement it at https://github.com/apache/datafusion/pull/12116 in case it helps -- This is an automated message from the Apache Git Service.
