Also, change the order of your dates to define the range. Instead of 'between sysdate and sysdate-20' use 'between sysdate-20 and sysdate'.

“Also, you are subtracting 20 days, not years (date arithmetics work on days)”

Just ignore this. Not sure why I thought you were trying to substract 20 years…

Why do you need to convert dates to char ?Also, you are subtracting 20 days, not years (date arithmetics work on days)

If CREATEDT is a date column, don’t use TO_CHAR() to convert it to a text string in ‘DD/MM/YYYY’ format. And don’t convert SYSDATE to a text string in ‘DD/MM/YYYY’ format. As soon as you convert to those formats, you mostly make it impossible to compare for a date range. Leave the values alone and just compare them directly to each other. — Tom
