是否有传递DbType作为参数的通用方法

Question

I need to execute this parameterized query, or an equivalent:

ALTER TABLE tableName ADD COLUMN ? ?

with the parameters as the name of the new column, and the data type. For example, if I pass in 'Name' DbType.Double, then it would resolve to:

ALTER TABLE tablename ADD COLUMN Name FLOAT

I can't just create a mapping between DbType and the name of the field type, as the code's working on the IDbConnection interface, not a specific implementation. Is there a generic way of doing this? Right now I've got a separate mapping for each implementation, which is obviously far from ideal.

您将必须动态地执行此操作，并且查看特定于提供程序的翻译可能很有意义（以便提供程序可以提供自己的映射）。
