This still gave me a sytax error. The other suggestion to multiply the interval field by 1 year also gave me a syntax error.
ii_purchased is a timestamp without time zone
ii_expected_life is a smallint
Any other suggestions?

I have to add a number of years to a date field. The years come from
another field in the table.
I know I can do this:
select (ii_purchased + interval '3 year') as date from inventory_item;
But I need to replace the 3 in 3 years with another field from the same
table ii_expected_life but I can't seem to do that without getting
syntax errors
Maybe something along lines:
select (ii_purchased + interval year_int::text||' year') as date from inventory_item
I am guessing at the data type of the field.
