### What feature or improvement would you like to see? It will be nice to support reading from union columns from databases that support them when using the `database/sql` adapter. For example, in DuckDB, this should work: ```go // Register "duckdb" as described in https://pkg.go.dev/github.com/apache/arrow-adbc/go/adbc/sqldriver // Error handling and closing resources omitted for brevity db, err := sql.Open("duckdb", "") _, err = db.Exec("create table test(a union(u varchar, v int))") _, err = db.Exec("insert into test values('aba'),(2)") rows, err := db.Query("select * from test") for rows.Next() { var s any err = rows.Scan(&s) fmt.Println(s) } if rows.Err() != nil { fmt.Println(rows.Err()) } ``` This should print: ``` aba 2 ``` but currently prints: ``` Not Implemented: not yet implemented populating from columns of type sparse_union<u: type=utf8, nullable=0, v: type=int32, nullable=1> ``` I have a draft PR ready if the enhancement makes sense. -- This is an automated message from the Apache Git Service.
