To update the field in database using Raw SQL?

Question

I need to update IsIgnored field based on senderId when I check in where condition,It not identifying senderId which I compared from loop.It throws exception like ambiguous column name 'senderid'.Guide me on this to resolve this issue.

  foreach (var senderId in senderIdList)
                    {
                        using (var context = new BSoftWEDIIContext())
                        {
                           var ediDocuments = context.EDIDocuments.SqlQuery("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and  edi.SenderID =senderId and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0" );

                        }

Tried like this:

 var ediDocuments = context.EDIDocuments.SqlQuery("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and  edi.SenderID ='149825353' and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0", new SqlParameter
                            {
                                ParameterName = "senderId",
                                DbType = System.Data.DbType.String,
                                Value = senderId
                            });


  foreach (var senderId in senderIdList)
                    {

                        using (var context = new BSoftWEDIIContext())
                        {
                            var ediDocuments = context.EDIDocuments.SqlQuery("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and  edi.SenderID=@senderId and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0", new SqlParameter("@senderId", senderId));

You need to add the sql parameter to your query.

  using (var context = new BSoftWEDIIContext())
                {
                    foreach (var senderId in senderIdList)
                    {
                        context.EDIDocuments.ExecuteSqlCommand("Update EDIDocument SET IsIgnored=1 from EDIDocument edi  inner JOIN  FileDetails files on edi.FileDetailsId = files.Id where edi.IsDeleted = 0 and edi.SenderID=@senderId and edi.DocumentTypeID != 3 and edi.DocumentTypeID != 5 and edi.DocumentTypeID != 2 and edi.IsIgnored = 0 and files.IsDeleted = 0",
                            new SqlParameter
                            {
                                ParameterName = "senderId",
                                DbType = DbType.Int32,
                                Value = senderId
                            });
                    }
                }
