DataAdapter: Update unable to find TableMapping['Table'] or DataTable 'Table'

Question

This code snippet is throwing an error:

Update unable to find TableMapping[\'Table\'] or DataTable \'Table\'.) on adapter.Update(ds); line

Answer 1

It's because .NET cannot assume that the table name in the DataSet/DataTable is identical to the database table. Thus .NET warns you about it.

To solve it you need to add a mapping to the DataAdapter:

da.TableMappings.Add("TableNameInDb", "TableNameInTheDataSet");

However, even if you have specified a name in the DataSet or the DataSource it still doesn't work, since the adapter seems to forget the name.

I only got it working by using:

da.TableMappings.Add("Table", "TableNameInDb");
