标签：query match turn param 项目 matching xxx return tab
问题描述：
MVC5项目，利用执行sql的方式获取数据，但是在利用预编译执行的时候报错了，字段XXXwhich was not supplied.
其实就是这个参数传了个null导致的。在传参数之前做个判断，如果为null就赋值为空串即可。
if (string.IsNullOrEmpty(name)) { name = string.Empty; }
String sql = "select a.Id,a.UserName,a.TrueName,ISNULL(b.OTM, ‘0‘) as Flag from SysUser a left join FIX_MatchingModel b on cast(a.Id as varchar) = b.OTM and b.Id = @matchingId Where a.DepId = @DepId order by b.OTM desc";
SqlParameter[] sqlParameters = { new SqlParameter { ParameterName = "matchingId", Value = matchingId }, new SqlParameter { ParameterName = "DepId", Value = depId } };
DbContexts DbContext = new DbContexts();
return DbContext.Database.SqlQuery<UserView>(sql, sqlParameters).ToList();
