在ormlite中插入特殊字符（从动态创建的表）

Question

我使用C＃，我创建了一个表，使用ServiceStack.OrmLite，对应于在运行时创建的类类型。需要明确的是，我做了以下内容：

• 建立在运行时（employeeType）的类型后，我能做到以下几点：

db.CreateTableIfNotExists(employeeType);

这将创建对应Employee表（动态创建的类型“员工”）。

• 实际上，我的问题是Employee表列名包含一些特殊字符（如：％，/ ...等）。创建表的方式和我刚刚描述的一样，但是当我尝试在此表中插入一行时，由于SQL语句中的语法错误（由于列名中存在特殊字符），我产生了一个异常。我有excption是以下（检查this）：

System.Data.SqlClient.SqlErrorCollection: Incorrect syntax near '('.\r\nMust declare the scalar variable \"@TokenRequestsPerSec_Request\"."

有关信息，我在表中的列的名称是“TokenRequestsPerSec_Request \秒”这样的问题是与“\”

我用下面的插入在Employee表柱：

var typedApi = db.CreateTypedApi(employeeType);

typedApi.Insert(employeeInstance);

请检查here地看到OrmLite到SQL服务器执行的INSERT语句：

exec sp_executesql N'INSERT INTO "ScanADFS" ("MonitoredObjectId","ScanDate","ScanDateInMs","EntityStatus","SystemServiceStatus","CertificateServiceStatus","FederationServiceStatus",

是否有逃避OrmLite INSERT语句中特殊字符的解决方案吗？

谢谢你的帮助！

你可以尝试这样的

查询字符串= “SELECT * FROM用户其中id = ORDER BY \？” usernum＃\ “”;

或

select * from test order by“username＃”desc;
