We are using azure table storage and have thousands of tables using the same schema. Now we are looking to add another column to these tables. How do we add another column to our existing tables without deleting the table and re-adding it?

推荐答案

Windows Azure表存储实际上没有列.每个实体(例如，行)只是一组属性，没有固定的架构.如果您使用强类型的类向表中写入数据，则只需将新属性添加到该类中.

Windows Azure Table Storage doesn't actually have columns. Each entity (e.g. a Row) is simply a set of properties, with no fixed schema. If you're using a strongly-typed class to write to your table, then you just need to add your new property to that class.

对于没有新属性的旧行，您的类对象中的值将设置为其默认值.

For older rows that don't have the new property, the value in your class object will be set to its default value.
