Oracle to_date return incorrect result
I have a table 4 columns - Code, Status, EffectiveDate (EFF_DT), EndDate (END_DT). All the columns are Varchar2 type. EFF_DT and END_DT has ISO format date (YYYY-MM-DD) with NULL values for few rows. Need to get the rows which has END_DT greater than today's date.
While executing the below query, it returns all the Not NULL rows for END_DT. Do not compare the END_DT at all.
select code, status, EFF_DT, END_DT
from (
select CODE, EFF_DT, Status,to_date("END_DT" ,'YYYY-MM-DD' ) as END_DT
from xxx.ZZZ
) TAB
where to_date(TAB.END_DT ,'DD-MM-YY' ) > to_date(CAST(CURRENT_TIMESTAMP as Date), 'DD-MM-YY')
ORDER BY 1 ASC
But the below query compares the END_DT and returns the result properly -
SELECT "TAB"."CODE" , "TAB"."STATUS" AS "STATUS" , "TAB"."EFF_DT" , "TAB"."END_DT"
FROM xxx.ZZZ "TAB"
WHERE ( (to_date("TAB"."END_DT",'YYYY-MM-DD') > to_date(CAST(CURRENT_TIMESTAMP as Date), 'YY-MM-DD')) )
ORDER BY 1 ASC
What is going wrong with the 1st query?
I see difference in return value of END_DT.
For the 1st query, the data is coming like -
while as for the 2nd query, the data is coming like

replaceto_date(CAST(CURRENT_TIMESTAMP as Date), 'DD-MM-YY')withcurrent_date. Never callto_date()with a parameter that is already a date or timestamp values. That only converts the date to a varchar just to convert that back to a date which it was to begin with

Why on earth are you storingDATEvalues in aVARCHARcolumn? That is a horrible idea.
