DateValue is a date column that contains the posting date of transaction. A query should label each transaction based on how many days have elapsed since the transaction was posted. The requested ranges are

$0$

$-$

$30$

$$days$,$

$31$

$-$

$60$

$$days$,$ and greater than

$90$

$$days$.$ How does the following CASE state fail to label the transcations appropriately? CASE WHEN DATEDIFF$($d$,$ DateValue, CURRENT$\_$TIMESTAMP$)<=90$ THEN $\text{'}61-90$ days'
