How to create a list of documents and also be able to open them in SharePoint 2013 online?
The documents are stored in an on-premise SQL Server database table.
How I was going about it was to
- Create a WCF service in Visual Studio
- Host that service in IIS
- Create an External Content Type in SharePoint Online
- Add the WCF service connection
- Export and Edit the BDC model from SharePoint Online BCS to include <MethodInstance Type="StreamAccess"...
- Import the BDC model back to SharePoint Online BCS
- Create a List
- Click on the link and open the file
I'm having issues after step 6...
I successfully imported the BDC model back into SharePoint Online BCS, but I don't know how to create a list with the document link. I also don't know if my code is correct within the WCF service or the BDC model I edited. I am using a byte[] (byte array) to pass an image sql datatype. See code and picture below:
This is what happens if I try to edit the DocumentReadStream Operation....

{
List<Documents> LD = new List<Documents>();
string ConStr = "data source=server_name; initial catalog=database_name; integrated security=False; User ID=xxxxxxx; Password=xxxxxx";
SqlConnection con = new SqlConnection(ConStr);
SqlCommand cmd = new SqlCommand("Select TOP 2 DocumentID, DmeName, DmePermissions, Content FROM DME_SP", con);
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
while(dr.Read())
{
Documents d = new Documents();
d.DocumentID = int.Parse(dr[0].ToString());
d.DmeName = dr[1].ToString();
d.DmePermissions = dr[2].ToString();
d.Content = (byte[])dr[3];
LD.Add(d);
}
dr.Close();
con.Close();
return LD;
}
}
}
