eq (equals), eq_ and cmpFor historical reasons, two 'CompareEquals' functions exist: 'eq' (CompareEquals) and 'eq_' (CompareEqualsWithNull). Both behave in the same way.
Example: eq_(totalprice, grossprice) is equivalent to or(and(isNull(totalprice), isNull(grossprice)), not(or(isNull(totalprice), isNull(grossprice))), eq(totalprice, grossprice)) | ||||||
