We always used the SQL Server ODBC driver for connection.
However, SQL Server data are not accepted on servers that doesn't allow SSL 1.0.
Therefore we want to use other drivers ({SQL Server Native Client 11.0} or {ODBC Driver 13 for SQL Server} or {ODBC Driver 17 for SQL Server}).
Using these other drivers we get an error updating a datastore with a nvarchar(max) (nvarchar(max) in the SQL table): The data types nvarchar(max) and ntext are incompatible in the equal to operator.
I found a difference in the created syntax (createsyntaxfromsql) between the SQL Server and the other servers.
In SQL Server the nvarchar(max) column is defined with updatewhereclause=no, while in the other servers it is updatewhereclause=yes. This explains the error.
I can solve the problem with a modify updatewhereclause=no, but I think it is better that it works fine without a hack.
I wonder if there is a bug in the ODBC driver or in Powerbuilder (we use PB 2017 R3).
Has somebody the same problem and what to do about it?
Thank you for reading,
