I am using a grid component (delphi) connected via Postgres ODBC , and via Datasource - ADOTable - ADOConnection to a postgres database. All works well. Tried using the PostgreSQL Native Provider, built a working connection string. It connects OK but I have only read access to the data (in the grid I cannot edit or add any rows). I have also tried several other OLEDB providers but they all exhibit the same behaviour. Why does ODBC work and PostgreSQL Native Provider (or other OLEDB's) not work? Help would be appreciated on this as I have spent a long time researching what to use for my future commercial projects. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
