[01004][0] [Microsoft][ODBC SQL Server Driver]String data, right truncation

This will happen when the size of the buffer created by application is less than the length of data retrieved from table.Mean s length of the column in the application specs is less than length of column in the database.
Practically in an enterprise this will happen only when someone plays with these lengths[either application end or database end].

So the approach is to narrow down the problem from View->Table->column.After this check whether the problem is with application specifications or with the database table specifications.

Microsoft SQL Server JDBC Driver version 2.0

Microsoft SQL Server JDBC Driver version 2.0 supports both JDBC 3.0 and JDBC 4.0. To support backward compatibility and possible upgrade scenarios, the JDBC Driver version 2.0 includes two JAR class libraries in the installation package: sqljdbc.jar and sqljdbc4.jar.

The sqljdbc.jar class library provides support for JDBC 3.0 and requires a Java Runtime Environment (JRE) of version 5.0. The sqljdbc4.jar class library provides support for JDBC 4.0 and requires a Java Runtime Environment (JRE) of version 6.0 or later. The sqljdbc4.jar includes all of the features of the sqljdbc.jar as well as the new JDBC 4.0 methods.

The reason being, our Language,Country combination in the Regional and Language options[of control panel] doesn't fall under the Fully supported Locales.Hope this helps
