实体框架核心2中具有输出参数的Exec存储过程

Question

I'm trying to refactor code to use dbContext.Database.ExecuteSqlCommandAsync instead of 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;

I'm getting this error:

SqlException: Incorrect syntax near @personId

What's wrong?

您需要在参数之间添加逗号：

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