Exec的实体框架中的核心存储过程的输出参数2

Question

我试图重构代码使用dbContext.Database.ExecuteSqlCommandAsync，而不是SqlCommand

List<SqlParameter> parameters = new List<SqlParameter>(); 

parameters.Add(new SqlParameter("@certificateTypeId", "TA")); 
parameters.Add(new SqlParameter("@personId", 1m)); 
parameters.Add(new SqlParameter("@selfAssessment", xDocument.ToString())); 
parameters.Add(new SqlParameter("@selfAssessmentVersion", 1m)); 
parameters.Add(new SqlParameter("@sponsorPersonId", 1m)); 

var outputParam = new SqlParameter("@certificationEventId", SqlDbType.Decimal, 10); 
outputParam.Direction = ParameterDirection.Output; 
parameters.Add(outputParam); 

string sql = "[My Stored Proc] " + string.Join(" ", parameters.Select(ToEfString).ToArray()); 

// runtime value: [My Stored Proc] @certificateTypeId @personId @selfAssessment @selfAssessmentVersion @sponsorPersonId @certificationEventId OUT 

var result = await dbContext.Database.ExecuteSqlCommandAsync(sql, parameters); 

return ((SqlDecimal)outputParam.SqlValue).Value; 

我得到这个错误：

SqlException: Incorrect syntax near @personId

什么问题？

您需要添加逗号的参数之间：

[My Stored Proc] @certificateTypeId, @personId, @...
