Simple Oracle query: literal does not match format string

Question

I want to execute a simple function in Oracle. The signature is defined as follows:

CREATE OR REPLACE FUNCTION NewCaseListForValidation
(
                            


        

Answer 1

It's best not to rely on particular value in NLS_PARAMETERS settings, cause this will make your function break in the env with another NLS_DATE_FORMAT.

I'd explicitly specify date formatting in your function as suggested in the answer above

exec :rc := newcaselistforvalidation(to_date('2010-01-01','YYYY-MM-DD'),to_date('2011-01-01','YYYY-MM-DD'),100);
