Question

Database empty etag values

SDK Laserfiche Installation and Upgrades

Updated September 25, 2015

asked on September 25, 2015

We are having a problem exporting electronic documents using our SDK based tool we created for our clientele after we upgraded them to most current version of Laserfiche. The issue appears to be that documents placed in the system prior to the upgrade do not have an “etag” or “edoc_lastmod” values.

What is the best way to resolve this issue. We have over 100,000 records that this applies to.

Thanks,

The etag is basically a random value that changes whenever the document is modified (read more here), allowing client applications to detect changes and avoid unnecessary re-retrieval. The edoc_lastmodified column is the last modification timestamp for the electronic file portion of the document. I don't see why a null etag or edoc_lastmodified would prevent the documents from being exported.

We appear to be hung up on the SDK portion of the question. How about if I change the question. We upgraded one of our customers and noticed that all of their electronic document records in the database prior to upgrade are now missing the etag field. What is this field used for and how is the value calculated?

Thank you for the clarification. I went ahead and removed my question, since it may not be relevant.
