I want to update the type of a column named "password". At the moment it has type NVARCHAR(40) and I want it to be of type NVARCHAR(64). This is what I did:
<changeSet id="1 - change password length" author="chris311">
<update tableName="tablename">
<column name="password" type="NVARCHAR(64)"/>
</update>
</changeSet>
What else is there to do? Because this obviously does not change anything in the DB.
You're using the wrong refactoring operation. Try modifyDataType
