InvalidOperationException - 执行命令时,参数必须是数据库参数或值

Question

当我运行以下ExecuteStoreQuery时,会立即抛出InvalidOperationException并显示以下消息:

执行命令时,参数必须是数据库参数或值.

        SqlParameter param1 = new SqlParameter("@pNetworkHealthAssessmentID", pNetworkHealthAssessmentID);
        SqlParameter param2 = new SqlParameter("@pRiskAssessmentQuestionsID", pRiskAssessmentQuestionsID);
        SqlParameter param3 = new SqlParameter("@pUserID", UserID);
        SqlParameter param4 = new SqlParameter("@pSortOrder", pSortOrder);

        var result = db.Database.ExecuteSqlCommand("sp_RiskAssessmentQuestion_Copy2Network @pNetworkHealthAssessmentID, @pRiskAssessmentQuestionsID, @pUserID", "@pSortOrder",
                                      param1, param2, param3, param4)

存储过程的参数如下所示:

 CREATE PROCEDURE [dbo].[sp_RiskAssessmentQuestion_Copy2Network] (
 @pNetworkHealthAssessmentID bigint
,@pRiskAssessmentQuestionsID bigint
,@pUserID bigint
,@pSortOrder int
)

存储过程不会返回任何值.为什么我得到那个例外？我已经尝试了所有可能的解决方案但到目前为止都没有成功

Answer 1

您没有包括最后一个参数,"pSortOrder"用逗号分隔,它应该是第一个字符串的一部分.

var result = db.Database.ExecuteSqlCommand("sp_RiskAssessmentQuestion_Copy2Network @pNetworkHealthAssessmentID, @pRiskAssessmentQuestionsID, @pUserID, @pSortOrder"
, param1, param2, param3, param4)
