{noformat}
create table tbl_x (a int, b string); {noformat}
2. Insert data in the table

+----------+----------+
|1 |Prince |
|2 | John |{noformat}
4. Create view:
{noformat}
create view vw_x (b) as (select a from tbl_x);{noformat}
5. Try to read data from view:
{noformat}
Error while compiling statement: FAILED: SemanticException line 1:67 cannot
recognize input near ')' 'vw_x' '<EOF>' in subquery source in definition of V
IEW vw_x [ SELECT `a` AS `b` FROM ((select `tbl_x`.`a` from `default`.`tbl_x`))
`vw_x` ] used as vw_x at Line 1:14 (state=42000,code=40000) {noformat}
6. Drop the view
{noformat}
drop view vw_x; {noformat}
7. Create the view again with the below definition:
{noformat}
create view vw_x (b) as select a from tbl_x; {noformat}

{noformat}
select * from vw_x;
