> The Scala interface support save SHOW command result to table:

> {code}
> But SQL interface does not support it:
> {code:sql}
> spark-sql> create table t using parquet as SHOW TABLES IN default;
> Error in query:
> mismatched input 'SHOW' expecting {'(', 'FROM', 'MAP', 'REDUCE', 'SELECT',
> 'TABLE', 'VALUES', 'WITH'}(line 1, pos 32)
