RE: Query on Base64 Document Database Integration plugin

Hi Robert,

Thanks for the information. I just had another query - We receive the document from a payload in form of base64 string which we are required to convert to a document and dump it in Appian's Knowledge center. Is this action supported by this plugin?

The payload to trigger Appian process (exposed as a Web API) is as follows:

{

"clientId":"Abc",

"base64Document":"<Base64 String>",

"documentExtension":"docx"

}

Thanks,
Arjun

Hi Arjun -

When you transfer documents to your cloud database, you won't use a CDT.

The plugin smart service parameter for both insert document and query document should be SQL, and not a CDT reference.

Essentially, it's " take this doc id and intsert it into this database table" AND "select this base64 sting (document) and put it in this target folder".

--to retrieve the document using Get Base64 Document from Database node
"select base64 from myschema.mytable where docid = '"& pv!docid&"'"

--to put a document in the database
="insert into myschema.mytable VALUES (:documentId, :title)"
-- where documentId and title are node input parameters that you set in the smart service itself

To address the large size of your base64 string in your cloud mySQL database, create a table with a column of type longtext or longblob.
Either should have enough capacity.
