Symptom

A mapping which contains source columns with type "NVARCHAR" fails with an error similar to this one:

com.indy.engine.common.exceptions.EngineExceptionI: Exception for source column 4 and target column 4

Solution

Some RDBMS technologies and some JDBC drivers do not support NVARCHAR conversions.

Within your workspace, you can set a JDBC option to avoid this kind of conversion: 

- Edit the .md file of the target RDBMS technology

- On the root node (the server node), choose Advanced, and add the property "JDBC.BIND.MANAGE_SET_NSTRING_AS_STRING"

 127-01

- Save the technology
