Question

I have 2 issues with below query

1) I want to append ‘HDR’ before the output of below query

select unique count(quote_id)
from    T_CONV

I tried various ways

select 'HDR'|| unique count(quote_id)
from    T_CONV

select 'HDR' + unique count(quote_id)
from    T_CONV

but none of them is working

Please let me know how to do that.

2) I also want to ensure that output of count should immediately start after HDR without any spaces or tabs , for that I tried RPAD function but that is not working with count function.

help is highly appreciated

Answer 1

try this

select 'HDR' || count(quote_id)
from    T_CONV
