Bir postgresql veritabanına çok basit bir güncelleştirme ve çalışmıyor. Sql select deyimi düzgün ve doğru değerleri döndürür. Ben VB.NET ve postgresql 9.2 kullanıyorumNeden "çapraz veritabanı başvurusu yapılmıyor" alıyorum?
{"ERROR [0A000] ERROR: cross-database references are not implemented: "openerp.public.product_template"; Error while executing the query"}.
:
i güncelleme almak zaman, öyle hata atar.
Ben Tek istediğim açıklamasında Whats eşleşecek şekilde adı alanını değiştirmektir.

bu sorunu olduğunu, ancak kod ortasında o ExecuteNonQuery() bir SELECT sorgusu için gerekli değilse bilmiyorum – Steve
Genellikle db 'olarak yorumlanır birden fazla nokta ile bir tırnaksız tanımlayıcı belirtir Postgres tarafından istisnai tetikleyen .schema.table'. Nedeni, * db server log dosyasına * bakarak, fiili rahatsız edici ifadenin, varsayılan kayıt ayarları ile birlikte hata mesajıyla birlikte belgelendiğini görüyorum. –
@ErwinBrandstetter, bir "str_import_date = 22.08.2013" gibi. O ExecuteNonQuery bir hataydı, ama sorun erwin - - dize birleştirme her zaman – Steve
