c# – 带参数的ASP.NET ODBC查询

请帮帮我,我不知道下面的代码有什么问题：

OdbcConnection conn = new OdbcConnection(connString);
        String query = "INSERT INTO customer (custId, custName, custPass, "+
                       "custEmail, custAddress, custAge) VALUES (" +
                       "@ID, @Name, @Pass, @Email, @Address, @Age)";

        OdbcCommand exe = new OdbcCommand(query, conn);
        exe.Parameters.Add("@ID", OdbcType.UniqueIdentifier).Value = id;
        exe.Parameters.Add("@Name", OdbcType.VarChar).Value = name;
        exe.Parameters.Add("@Pass", OdbcType.VarChar).Value = pass;
        exe.Parameters.Add("@Email", OdbcType.VarChar).Value = email;
        exe.Parameters.Add("@Address", OdbcType.VarChar).Value = address;
        exe.Parameters.Add("@Age", OdbcType.Int).Value = age;
        conn.Open();
        exe.ExecuteNonQuery(); // ERROR [07002] [Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 6.

这段代码抛出了太少的参数.我尝试执行查询时出错.数据库很好,当我将值硬编码到查询中而不是使用参数时,它工作正常.

谢谢.

来自MSDN：

When CommandType is set to Text, the .NET Framework Data Provider for ODBC does not support passing named parameters to an SQL statement or to a stored procedure called by an OdbcCommand. In either of these cases, use the question mark (?) placeholder. For example:

SELECT * FROM Customers WHERE CustomerID = ?

将您的查询重写为

OdbcConnection conn = new OdbcConnection(connString);
    String query = "INSERT INTO customer (custId, custName, custPass, "+
                   "custEmail, custAddress, custAge) VALUES (" +
                   "?, ?, ?, ?, ?, ?)";

参数顺序计数！

编辑：参数可以这样添加：

OdbcCommand exe = new OdbcCommand(query, conn);
exe.Parameters.Add("ID", OdbcType.UniqueIdentifier).Value = id;
exe.Parameters.Add("Name", OdbcType.VarChar).Value = name;
exe.Parameters.Add("Pass", OdbcType.VarChar).Value = pass;
exe.Parameters.Add("Email", OdbcType.VarChar).Value = email;
exe.Parameters.Add("Address", OdbcType.VarChar).Value = address;
exe.Parameters.Add("Age", OdbcType.Int).Value = age;
