December 2020. ProCall Client in conjunction with Microsoft SQL Server.
Observation
Chatting in ProCall Client (using Microsoft SQL Server) is not possible: the chat window remains empty.
UCServer reports the error "EDatabaseConnection::GetEvents;Field 'ReplyToSeqID' not found".
Possible reason
As of UCServer version 7.0.0.2022, SQL table "ChatEvents" has been extended by columns "ReplyToSeqID" and "ForwardedFrom".
In certain constellations, the SQL database is not updated during an update/upgrade of the UCServer.
For example, when updating/upgrading from 6.4.10.3266 to 7.1.1.3548, the columns "ReplyToSeqID" and "ForwardedFrom" in dbo.ChatEvents may not be created.
Procedure
Check if the columns "ReplyToSeqID" and "ForwardedFrom" are present in the table dbo.ChatEvents.
Solution
In UCServer version 7.1.2 and higher, this behavior no longer occurs.
Workaround
As a workaround, you can manually create the columns ReplyToSeqID (int,NULL) and "ForwardedFrom (nvarchar(MAX),NULL) in the SQL Server table dbo.ChatEvents.
Example screenshot for a workaround: Allow null values for dbo.ChatEvents
