varbinary
If the table has a varbinary field type the insert/update failed with the error message Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.
I can't repro. Can you provide the log output with the log level set to Debug?
Just create a table
CREATE TABLE dbo.foo
(
NUM_TRF int,
NAME varchar(255),
DESCRIPTION varchar(1000),
REPORT varbinary(max)
)
on both sites ( source and destination) and try to synchronize this. The insert/update should be done using the CAST('some_data_in_report_filed' AS VARBINARY(MAX))
Works for me. Had to make NUM_TRF a primary key though, otherwise change tracking can't be enabled on the table. Do you have change tracking enabled on the table?
