``` create table kafka ( a UInt32, a_str String Alias toString(a) ) engine = Kafka; create table data ( a UInt32; a_str String ) engine = MergeTree order by tuple(); create materialized view data_mv to data ( a UInt32, a_str String ) as select a, a_str from kafka; ``` Alias type works as expected in comparison with MATERIALIZED/EPHEMERAL or column with default expression.
