asuman — Wed, 24 Jul 2019 15:09:18 GMT

In a data set we have a column of date in datetime format.

I want to increment the date with 2 months,4 hrs,10 min and 6 second.

Kindly help to write this query.

So you have column with DATETIME (not DATE).

You can use the INTNX() function to increment dates by periods. You will HAVE to use it to increment by MONTH, but since the value is DATETIME you need to use the DTMONTH interval. To increment by time just add the time value since both DATETIME and TIME values are stored as number of seconds.

want=intnx('dtmonth',have,2,'same')+'04:10:06't ;

If you don't tell INTNX() where in the target period you want it will set it to the BEGINNING of the period.

You want to use SAME, not BEGINNING or END.
