Hi Rudy,

Send Record
Document to Blob

is less work. :)

It’s fairly easy to write a method that loops through all the fields of the

Then, on the other end, use same method but ‘BLOB to variable’

Works really well.

Re: v13 - Record to Blob?

2018-07-31 Thread Chip Scheide via 4D_Tech

yes -
but I was mistaken about the end use..

end use is for archiving deleted records.
record formats may change, and blob data is not user readable

It’s fairly easy to write a method that loops through all the fields of the

Then, on the other end, use same method but ‘BLOB to variable’

I considered this approach -
but the need is for data passing between processes, so writing to disk 
is not really 'efficient'.

I went/am going with a simple convert it all to text approach.  The 
data will not need to deal with blobs, or pictures so this will do for 
now.

Hi Chip,

No native command as you might have learned from the answers on your post.
Not too difficult to implement yourself. Below is what I've been using for a 
long time.
I just noticed that I did not delete the intermediate disk document, but if 
untouched, the files in the temporary folder are automatically removed by the 
OS after three days (at least on macOS).

I think this would be very useful as a native command and trivial to implement 
(already in the plugin API, I think). If you agree, here is the feature request:

No 4D native command. You need Rob’s “API Pack” it has command to go "API 
Record to BLOB" and “API BLOB to Record"
