Hi Gurus,
   I have a table with datatype as bitstrings
create table test_a (b bit(3));
insert into test_a values ('111');
This will convert a bit to a number
select to_number((substring(b,1,1)::int),9)+3 from test_a;
How will I convert a Number to a bit
insert into test_a values (to_char(1,'9'));
ERROR:  column "b" is of type bit but expression is of type textHINT:  You will need to rewrite or cast the expression.
Please help me
