voglio fare un piccolo cambiamento in una tabella di Access utilizzando UCanAccess tramite NetBeans, ma ho incontrato un problema alla lineadatabase di aggiornamento errore di accesso "non supportato ordine di collazione sorta" da Java
pst.executeUpdate();
dettagli del database:
database name : duruBistro.accdb
table name : person
field names: tc_no (text)
name (text)
surname (text)
salary (number)
Codice:
Connection conn = DriverManager.getConnection("jdbc:ucanaccess://C:\\Users\\ysnndr \\Documents\\accessDB\\duruBistro.accdb");
String query = "UPDATE PERSON SET SALARY = ? WHERE TC_NO = '189'";
PreparedStatement pst = conn.prepareStatement(query);
pst.setInt(1, 2500);
pst.executeUpdate();
Eccezione:
012.351.run:

formatta correttamente l'eccezione? – HaveNoDisplayName
È possibile eseguire direttamente lo stesso lavoro SQL in Access? È possibile che il tuo driver JDBC non supporti il textSortOrder che hai configurato sulla tua chiave primaria, ma non sono un esperto di Access. – Rup
Perché non stai usando un parametro 'TC_NO' come lo sei per' SALARY'? – MadProgrammer
