> If we don't plan to support concat operator (||), we should throw a decent error message early.
> The error is cryptic:
> 0: jdbc:drill:schema=dfs> select cast(l_orderkey as varchar(10)) || '-' || cast(l_partkey as varchar(10)) from cp.`tpch/lineitem.parquet`;
> Query failed: Query stopped., Line 65, Column 29: "value" is neither a method, a field, nor a member class of "org.apache.drill.exec.expr.holders.VarCharHolder" [ bc85685d-e08a-494b-aa9f-5b3fa4ee4033 on atsqa4-133.qa.lab:3

> Error: exception while executing query: Failure while executing query. (state=,code=0)
> I believe that error that I'm getting from the query below is the result of not throwing "Unsupported" message earlier.
> Please correct me if I'm wrong.
