This is my code: OleDbConnection connection = new OleDbConnection( Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\\Offline.accdb;Persist Security Info=False); connection.Open();

This is my code:

OleDbConnection connection = new OleDbConnection(
   "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\\Offline.accdb;Persist Security Info=False");
connection.Open();
OleDbCommand command = connection.CreateCommand();
command.CommandText = "SELECT DISTINCT B.* FROM BlankFormSubmissions B, Actions A WHERE A.FormName = 'FindingNemo' AND B.ProcessName = A.ProcessName AND B.ActionName = A.ActionName AND B.ID = 12 OR B.ID = 13 OR B.ID = 14 ORDER BY B.ID";
OleDbDataReader reader = command.ExecuteReader();
while (reader.Read())
{
    string xml = (string)reader["XML"];
    // ... do something with xml
}

The column, “XML”, is an Access Database table column, of type memo.

The value of xml always contains only the first characters of the XML. I’m guessing it’s the first 256 characters. Obviously, I need all of the characters in the string.

Anyone know how to fix this?

Thanks 🙂

    The problem could be the memo field itself;

    Memo fields can’t be used in Aggregate Arguments ( like Max, Var, Sum etc. )
    If used in ‘Group By’ totals in a query only the first 255 characters are returned.
    ‘Having’ and ‘Where’ clauses in Group Aggregate functions also return only the first 255 chars
    However, using ‘First’ or ‘Last’ arguments return the full length of the string.

    Is this the entire SQL statement?
