How can I compare two datetime queries in SQL?
This can be easily done using equals to(=), less than(<), and greater than(>) operators. In SQL, the date value has DATE datatype which accepts date in ‘yyyy-mm-dd’ format. To compare two dates, we will declare two dates and compare them using the IF-ELSE statement.
How do you compare time in SAS?
In SAS, you use the INTCK function to calculate the difference between two timestamps. You provide the start time, the end time, and the desired interval, and the INTCK function returns the difference in seconds, minutes, or hours. The INTCK function works both with time variables and datetime variables.

To compare a long value to a shorter standard, put a colon (:) after the operator, as in this example: /* correct method */ if TourGuide=:’D’ then Chosen=’Yes’; else Chosen=’No’; The colon causes SAS to compare the same number of characters in the shorter value and the longer value.
How does SAS store date and time values?
SAS dates are stored as simple integer numbers. SAS time/datetimes are stored as decimal numbers to include 10th and 100th of seconds. For time values the integer part is the number of seconds from midnight. For datetime the integer part equals the number of seconds from January 1,1960.
How do you find the difference between two dates and time in SAS?
In general, the difference between two SAS dates in days can most easily be calculated as duration=end_date – start_date. If you want to consider people who (in this case) are admitted and discharged on the same date as having a duration of 1 day, then the formula becomes duration=end_date-start_date+1.
