this will help You've got multiple problems here. One, as pointed out in the comments, is that INNER JOIN cannot join to NULL (no join can, actually, but read on..) so where, for example you write in your SQL:
INNER JOIN MaritalStatus AS m ON m.MaritalStatusDesc = @maritalStatusDesc
cmd.Parameters.Add(new SqlParameter("@maritalStatusDesc", string.IsNullOrEmpty(MaritalStatusDesc) ? (object)DBNull.Value : MaritalStatusDesc));
WHERE ... AND @maritalStatusDesc Is Not Null
cmd.Parameters.Add(new SqlParameter("@maritalStatusId", IDLookupHelper.GetIDForMaritalStatusDesc(msdTextBox.Text)));
public object GetIDForMaritalStatusDesc(string msd){
    return DBNull.Value;
  using(SqlCommand sq = new SqlCommand(
    "connstr here", 
    "SELECT ID FROM MaritalStatusWHERE Desc = @msd"
    sq.Parameters.AddWithValue("@msd", msd); //note: google "can we stop using addwithvalue already"

      return sq.ExecuteScalar();
    } catch {
      return DBNull.Value

Empty string inserting a zero, not a null

Tag : mysql , By : Revision17

I think the issue was by ths following , MySQL by default attempts to coerce invalid values for a column to the correct type. Here, the empty string '' is of type string, which is neither an integer nor NULL. I suggest taking the following steps:
Change the query to the following: INSERT INTO foo (bar) VALUES (NULL); Enable strict mode in MySQL. This prevents as many unexpected type and value conversions from occurring. You will see more error messages when you try to do something MySQL doesn't expect, which helps you to spot problems more quickly.

With these it helps I am reading and storing data in MySQL and some columns data consists of empty values. e.g , the answer I found which works perfectly well is ..
  data_buffer = [ts] + data_tmp[1:]
  data_buffer = [v if v is not "" and v is not " " else None for v in data_buffer]
  print data_buffer

this will help maybe try with the use of ->execute()
remove the bindParam's and change to this:
    ':nombre' => $datos['nombre'],
    ':usuario' => $datos['usuario'],
    ':password' => $datos['password'],
    ':rol' => $datos['rol'],
    ':estado' => 0

Any of those help You create a temporary copy of Student each time you're going to addMark, and discard it afterwards. You need not to copy it, but use reference, like this:
for (auto& stud: listOfStudents) /* stud.addMark */
for (const auto& stud: listOfStudents) /* stud.getMark */
float getMark(const string &module) const throw (NoMarkException);

Inserting a string into the last empty space of another string in Python

I think the issue was by ths following , str.rsplit the second string and str.join the appropriate tokens back together:
t1, t2 = mystring2.rsplit(' ', 1)
' '.join((t1, mystring1, t2))
# 'Lorem Ipsum (Lorem Dolor Amet English French German Elit)'
