Sean Hsuan-Yi Chu updated DRILL-2054:
-------------------------------------
Description:
For example, the query:
select n_nationkey || ' + ' || n_name || ' = ' as CONCAT, n_nationkey, ' + ' as
PLUS, n_name from cp.`tpch/nation.parquet`
should print out
CONCAT n_nationkey PLUS n_name
0 + ALGERIA = 0 + ALGERIA
1 + ARGENTINA = 1 + ARGENTINA
2 + BRAZIL = 2 + BRAZIL
3 + CANADA = 3 + CANADA
... ... ... (rows/records are omitted due to space limitation)
was:
`||` can be used as either "logic operator" or "varchar operator"
1. For boolean inputs, it is "OR"
2. For varchar inputs, it is should be "concat" (of strings)
> Support `||` as "concat operator" for varchar inputs
