Hi:

I need a query... which should able to assign a value or return all records when I assign a value of 'ALL' or NULL to a substitution variable.

for instance:

select *
from tab1
where &col = 'xyz';

then it should should return all the records which matches the condition of 'xyz' for col1

I also need this query return all records when I use the following:

select *
from tab1
where &col = 'ALL';

select *
from tab1
where &col = NULL <NO VALUE ENTERED>;
