title: failed because the DataColumn is a computed column
body: <p>i'm having a another problem. I have on one dataset column set expression so it calculates for me some stuff, but when i use my awesome SQLite update function it fails with message: "<em>The column mapping from SourceColumn 'blablabla' failed because the DataColumn 'blablabla' is a computed column.</em>"
  In dataBase that field is set as NUMERIC, so it accepts any number, the expression i'm using for this field in dataset is this "<strong>Convert((inventkiekis - lik_pagr) * 1000, 'System.Int32')/1000</strong>".</p>
  
  <p>What to do to be able update my table? that function works very nice until i have computed column.</p>
  
  <p>thanks.</p>
  
  <p>PS: My Update Code:</p>
  
  <pre><code>public Int32 atnaujintiDB(DataSet dataSet, String lenta)
      {
          int numRowsUpdated = 0;
          using (kaupykliuduomConn)
          {
              if (kaupykliuduomConn.State != ConnectionState.Open)
                  kaupykliuduomConn.Open();
              using (SQLiteTransaction transaction = kaupykliuduomConn.BeginTransaction())
              {
                   using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + lenta, kaupykliuduomConn))
                  {
                      using (sqliteAdapter.InsertCommand = new SQLiteCommandBuilder(sqliteAdapter).GetInsertCommand())
                      {
                          numRowsUpdated = sqliteAdapter.Update(dataSet, lenta);
                      }
  
                  }
                  transaction.Commit();
                  transaction.Dispose();
              }
  
  
          }
          return numRowsUpdated;
      }
