[SQL] column names with - and (

[maria s]

Hi All,
When I am fetching the data from a table,
I am giving the column names with - and ( and ) like IL-a, IL-a(p30) etc..

select x1 as IL-a, x2 as IL-a(p30) from abc

But I am getting

ERROR:  syntax error at or near "-" and also t "(" , ")"

Can anyone help me to fix this?

Thank you,
Maria
