I never used the delegator in this purpose. I think it's not possible
and need extend EntityCondition to support this.

That's not really very efficient especially if youre trying to find a few
items from a hundred thousand. Putting it in a list would easily give you an
OutOfMemoryException. I have a workaround for this but its done using
SQLProcessor which could be problematic later on. Any other suggestions?

One way could be
values = delegator.findList("EntityName", null, null, null, null, true);
List field1Values = EntityUtil.getFieldListFromEntityList(values, "field1",
true);
finalValues = delegator.findList("EntityName",
EntityCondition.makeCondition("field2", EntityOperator.IN, field1Values),
null, null, null, true);

i am familiar with findList and how to use EntityConditionList and
EntityExpr. But i am only familiar with comparing a column with a given
value (like new EntityExpr("columnName", EntityOperator.EQUALS, value).
What
i wanted to do is to compare 2 columns of an entity. For example, if it
were
written as an SQL, it would be something like "SELECT column_a, column_b
FROM table WHERE column_a = column_b"
