Partial intervals are not counted. ); put cc hex4. 1 Answer. I understand there still is a discrepancy with the yrdif function but unless there are no other options with intck to get a decimal the yrdif might be my only option. I believe this happens because the alignment option in the INTCK function defaults to DISCRETE, which counts interval boundaries in between two dates, rather than CONTINUOUS, which counts full intervals in between dates, shifted to the start date. LOB ,MMD. – Cliff AB. The ROUND function is the same as the ROUNDE function except when the first argument is halfway between the two nearest multiples of the second argument, ROUNDE returns an even multiple. Then try the intck function for the difference. Adj_form1=floor((intck(‘month’,dob,today)-(day(today)<day(dob)))/12); The FLOOR function in this formula will round down to the nearest whole number. WEEK_NUM AS SELECT DISTINCT MUC. For more information on the INTCK and INTNX functions, see INTCK and INTNX: Two essential functions for computing intervals between dates in SAS, an article by @Rick_SAS. If Date is numeric this will fail with your attempt: date>"&date1". You can fix this by using the CONTINUOUS method in INTCK. The INTNX function returns the SAS date value for the beginning date, time, or datetime value of the interval that you specify in the start-from argument. It will not print a function derived from other variables. proc sql noprint; create table daystoOverdue_list as select distinct business_object_rk , DateDiff (DAY, value_dt, Today ()) as value_dt from case_DataTable_d as tbl where tbl. For example, if you are using the INTCK function to count the months between two dates, regardless of the actual day of the month specified by the date in the beginning value, SAS treats it as the first of that month. ERROR: Unresolved reference to table/correlation name s_cases. cchex=put (cc,hex4. 2, a fifth argument to the INTCK function was added which will also help calculate a person's age. 33 rounded to the nearest tenth equals 3*0. The INDEX function searches source, from left to right, for the first occurrence of the string specified in excerpt, and returns the position in source of the string's first character. end1=input (end,yymmdd8. The form of the INTCK function is. The INPUT function cannot be called by %SYSFUNC. For example: An application is submitted at 1pm on 2nd Jan 2014, and now it is 10am 3rd Jan, then SLA is 4 hours (1pm to 4pm on 2nd Jan, and then 9am to 10 am on 3rd Jan) Another application is submitted at 5pm. Example This program computes age using each of these methods (YRDIF, dividing by 365. The INTCK function works both with time variables and datetime variables. timedelta (18). DATETIME values are seconds. Desired result is the SURV_MM and N_MONTH is what I ended up with INTCK function as coded below. If you are performing a calculation such as age, or tenure, then be sure to use the 'continuous' parameter of intck(). This was not a stated requirement of the original problem. The syntax of INTCK function is as follows: INTCK (interval, start date, end data, method) interval: Interval to calculate (day, week, month, quarter, year etc. Use INTCK to calculate the number of days between the patient’s current record’s date and the last date. 1 Answer.
