问题描述
我有一个存储过程，它使用几个表并创建一个交叉表结果集.为了创建交叉表结果集，我使用了基于表中记录动态生成的 CASE 语句.
I have a stored procedure which uses a couple of tables and creates a cross-tab result set. For creating the cross-tab result set I am using CASE statements which are dynamically generated on basis of records in a table.
是否可以使用 ADO.NET 实体框架从此 SP 生成实体?因为每次我为特定的 SP 尝试 Get Column Information 时，它都会说 选定的存储过程不返回任何列.
Is it possible to generate an entity from this SP using ADO.NET Entity framework? Cuz each time I try Get Column Information for the particular SP, it says that The selected stored procedure returns no columns.
任何帮助将不胜感激.
推荐答案
我团队的一个成员最近遇到了这样的事情，其中一个存储过程正在生成各种动态 SQL 并返回计算列，因此数据上下文没有知道该怎么做.我自己还没有尝试过，但这是他声称有效的解决方案:
A member of my team recently encountered something like this, where a stored procedure was generating all kinds of dynamic SQL and returning calculated columns so the data context didn't know what to make of it. I haven't tried it myself yet, but this was the solution he claimed worked:
解决办法很简单，就是放行立即关闭；"进入过程.这允许数据上下文实际上生成返回类.这在这种情况下有效，只是因为proc除了查询什么都不做数据.
您只需要SET FMTONLY OFF"proc 足够长以生成班级.然后您可以将其注释掉.
You only need the "SET FMTONLY OFF" in the proc long enough to generate the class. You can then comment it out.
