具有数据库字符的SQLException

Question

I have data in a table:

CodeID    ColOne          ColTwo
---------------------------------------
1         DATAONE         DATAONE
2         DATATWO-Test    DATA-TEST1

Here is my code:

public static Codes [] Fetch(IDataProxy proxy, string whereClause, params FetchParameter [] parameters)
{
    List<Codes> list = new List<Codes>();
    using(IDbCommand cmd = proxy.Connection.CreateCommand())
    {
        cmd.CommandText = "SELECT [CodeID],[ColOne],[ColTwo] FROM [Codes]";
        using(IDataReader reader = cmd.ExecuteReader()) {
            while(reader.Read()) {
                list.Add(new Codes(reader));
            }
        }
    }
    return list.ToArray();
}

When I retrive the second result, I get an error message on Line 7 at "cmd.ExecuteReader()". The error message is as follows:

Unclosed quotation mark after the character string 'DATATWO'. Incorrect syntax near 'DATATWO'.

What am I doing wrong?

Thank you for all your help!

Edit :

Here is Codes:

internal Codes(IDataReader reader)
{
   this.CodeID = reader.GetInt32(0);
   this.ColOne = reader.GetString(1);
   this.ColTwo = reader.GetString(2);
   this.DataState = System.Data.DataRowState.Unchanged;
}

I overlooked something, in my example, I didn't include my "where" clause and the select statement was: where ColOne = 'DATATWO-Test . I didn't have the closing ' after the value.
