I have a below columns in table

Table 1

USERID INT 4
DRUGCODE INT 2
READTYPE INT 2
STARTDAY INT 4
ENDDAY INT 4
LASTUPDATEDDAY INT 4

SAMPLE DATA

USERID, DRUGCODE , READTYPE ,STARTDAY,ENDDAY,LASTUPDATEDDAY
1,30,1,NULL,6,200
1,30,5,NULL,6,200
1,45,1,NULL,6,200

2,7,1,23,NULL,360
2,4,3,23,NULL,360

3,43,1,NULL,NULL,234

Now I want to replace the STARTDAY NULL value with ‘0’ & ENDDAY NULL value with LASTUPDATEDDAY. Please help on writing SCRIPT. Thanks!

UPDATE Table1
SET ENDDAY = LASTUPDATEDDAY
, STARTDAY = CASE WHEN STARTDAY IS NULL THEN 0 ELSE STARTDAY END

ENDDAY = COALESCE(EndDay,LASTUPDATEDDAY)
STARTDAY = COALESCE(StartDay, 0)
