fetching data into existing workfile

[tjriddle]

Here is the situation. I have monthly data variable in a workfile from 1965 to 2032, say CPI. I want to fetch updated data for 2009 to 2033 from an eviews data base but I do not want to overwrite the existing data from 1965 to 2008. In other words, I want to replace part of the time series, not all of it and be assured that the part of the data I am not interested in changing stays the same. I do not want to have to change the name of the time series either.

If the database only has data in it from 2009 to 2033, then you can merge in that data, and the original data from 1965-2008 will be left intact.

Otherwise I think the best option is rename the variable, fetch in the database version, merge the two series together, then rename it back.

Something like:

Code: Select all

rename cpi temp fetch cpi smpl 2009 2032 temp=cpi smpl @all d cpi rename temp cpi

I would suggest, as an improvement to the software, that you allow overwrites of just a prtion of the data. Much simpler.

It appears that in version five you had an option under "OBJECT" called "Update from DB" this option disappeared in version 6.

Will it do what I need?

Update from DB is still there in 6, but it does exactly the same thing as Fetch.
