Modifying a Date Field

Modifying a Date Field

Modifying a Date Field

How do I add a number of days/months/years to a date field.

e.g. in Access I can do the following:

Update [MyTable] set [mydate] = dateAdd('m', 2, [mydate])

This will add 2 months to all the [mydate] values.

How do I do something similar in Pervasive??


RE: Modifying a Date Field


I got this from the manual - hopefully it will help.


Date Arithmetic
The SRDE supports adding or subtracting an integer from a date where the integer is the number of days to add or subtract, and the date is embedded in a vendor string. (This is equivalent to executing a convert on the date).

The SRDE also supports subtracting one date from another to yield a number of days.

SELECT * FROM person P, Class C WHERE p.Date_Of_Birth < ' 1973-09-05' and c.Start_date >{d '1995-05-08'} + 30

RE: Modifying a Date Field

Thanks Tom - although I didn't need the convert on the date.

I simply did something like the following the following:

UPDATE "My Table" SET myDate = myDate + 365


RE: Modifying a Date Field


Glad I could help.  Thanks for the star.
