c# - 远程过程调用 (RPC) 协议(protocol)流不正确

Question

我使用 entityframework 5.0。我有很多测试。如果我单独运行一个测试，它会通过，如果我和其他人同时运行这个，它不会通过。测试之间没有联系。每次发送一个相同的查询。它不会被修改。

**query:**

insert [dbo].[Patient]
       ([AddressId],
        [FirstName],
        [LastName],
        [MiddleName],
        [MuthersName],
        [Sex],
        [BirthDate],
        [TAJNumber],
        [Height],
        [Weight],
        [PhoneMobil],
        [PhoneHome],
        [Email],
        [OtherDisease])
values (13 /* @0 */,
        'Peter' /* @1 */,
        'Peter' /* @2 */,
        'Peter' /* @3 */,
        'Maria' /* @4 */,
        1 /* @5 */,
        '1991-07-04T00:00:00' /* @6 */,
        '5464845' /* @7 */,
        170 /* @8 */,
        66 /* @9 */,
        '00456249864' /* @10 */,
        '00456249864' /* @11 */,
        'alma22@mailmetrash.com' /* @12 */,
        null)



select [Id]
from   [dbo].[Patient]
where  @@ROWCOUNT > 0
       and [Id] = scope_identity()

Answer 1

当我尝试插入一列数据类型为 float 的新行时，我遇到了这个问题。当我尝试插入 SQL Server 不支持的 Infinity 或 NaN 值时，引发了与您相同的异常。

如果您使用 Entity Framework ，建议使用 HibernatingRhinos assembly .您可以跟踪生成的查询并检测导致问题的参数。

如果您使用 TPT (Table-Per-Type)，SQL Profiler 将不会帮助您.
