ORA-01843 not a valid month- Comparing Dates

Question

I have a problem when try to select data from a table filtering by date.

For example:

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = \'23         


        

Answer 1

If you don't need to check exact timestamp, use

SELECT * FROM MYTABLE WHERE trunc(DATEIN) = TO_DATE('23-04-49','DD-MM-YY');

otherwise, you can use

SELECT * FROM MYTABLE WHERE DATEIN = TO_DATE('23-04-49 20:18:07','DD-MM-YY HH24:MI:SS');

Here, you use hard code date,if you directly compare then you must use DD-MM-YY HH24:MI:SS else you might get ORA-01849: hour must be between 1 and 12.
