Best approach to export data from Appian database

which formats are fine for you and why do you need to export the DB? - Then perhaps you can run your own query entity

Is it a normal operation that you are going to take or it is only one time activity? - Then go to Appian DB on mysql and export DB

How much data are you expecting to export?

Thank you for the quick response.

Data in any of the formats will be fine for us. I need to export the database tables for project purpose.

It is not a one time activity. We need to perform it once or twice a day.

The data we are trying to export is in bulk. There are many table and we have to export all the tables. 

Then I would use

"Export Data Store Entity to CSV" and i would create one csv per entity. Then save it in a folder and/or send it somewhere.

I have read about 'Export Data Store Entity to CSV' smart service and implemented the below code..

a!localVariables(
  local!exportDocId,
  local!errorMessage,
  {
    if(
      isnull(local!exportDocId),
      /*This link field contains the link that starts the export*/
      a!linkField(
        labelPosition: "COLLAPSED",
        links: a!dynamicLink(
          label: "Export to CSV File",
          saveInto: {
            a!exportDataStoreEntityToCsv(
              entity: cons!ENTITY,
              documentName: "CSV Export " & now(),
              saveInFolder: cons!FOLDER,
              onSuccess: a!save(
                local!exportDocId,
                fv!newDocument
              ),
              /*This displays an error if there is an issue executing the the save*/
              onError: a!save(
                local!errorMessage,
                "Error Exporting File to CSV"
              )
            )
          }
        )
      ),
      {}
    ),
    if(
      /*This only displays the download link if a valid document was created*/
      not(isnull(local!exportDocId)),
      /*This changes the link to a download link for the newly created document */
      a!linkField(
        links: a!documentDownloadLink(
          label: "Download CSV File",
          document: local!exportDocId
        )
      ),
      a!textField(
        value: local!errorMessage,
        readOnly: true
      )
    )
  }
)

I am able to export one csv file using this code in an interface. 

How to connect this interface with process model to get the data from multiple tables. Please provide the screenshot of the process model with node configuration demonstration if possible. 

I believe the poster above was suggesting that you implement this in a process instead of using an interface. An interface only allows you to export a single document at a time, but in a process you could export all of them and put them into a folder that could easily be retrieved later.

I dont think it is a good idea to do via interface.

as requested, this is how it looks in the process model.

Those two settings required to make it work,

Thank you for your help.

I am able to export data from multiple tables using multiple  'Export Data Store Entity to CSV' and 'Export Data Store Entity to Excel' smart services in the process model. I am able to download this data in my local system using 'User Input Task'. 

Now, I want to know how can I get this data on FTP site in place of downloading it on my local system?  

Hello,

i think you should open a different threat for that question, and perhaps check if there is someone already with the same issue.

One solution could be to do via API and for sure there are ways to do via sftp, but i dont have experience with that case.

Yes thanks for the suggestion. I will open a different threat for that.

While I am trying to export data from Appian database using 'Export Data Store Entity to Excel' smart service, I am facing

'Unable to export. Maximum number of columns exceeded: 50' error.

And that node failure due to which I am unable to export tables with more than 50 columns.

Please help me in resolving this issue.

I would try with the settings of the node, selecting the number of rows and perhaps have it split in two documents...

Please display it's configuration with a process model example as above. 

How do you develop your things in Appian? Is there anyone from your team you could ask support from if what you need is step by steps?

Don't get me wrong, but expecting that each single step of your development is in the community is not the aim of this.  You should go through what is suggested and try it yourself. If you don't manage, then ask the community the specific issues you might face, but asking that you have all the code and configurations here to solve your problem, is not what I understand this community is for.

Good luck
