I'm doing a delete button to delete data from db.
It is my Java code
private void btnUsunActionPerformed(java.awt.event.ActionEvent evt) {
try
{
int P = JOptionPane.showConfirmDialog(null,"Jesteś pewny usunięcia ?","Potwierdzenie",JOptionPane.YES_NO_OPTION);
if (P==0)
{
String query = "{CALL SZPITAL_DB.usun_uzytkownik(?)}" ;
CallableStatement cst = con.prepareCall(query);
cst.setString(1,txtLogin.getText());
cst.execute();
cst.close();
JOptionPane.showMessageDialog(this,"Usunięto !","Potwierdzenie",JOptionPane.INFORMATION_MESSAGE);
Reset();
}
}catch(HeadlessException | SQLException ex){
JOptionPane.showMessageDialog(this,ex);
}
}
PL/SQL Code
create or replace procedure usun_uzytkownik
(
ID IN LOGOWANIE.LOGIN%TYPE
)
IS
begin
delete LOGOWANIE WHERE LOGIN = ID;
commit;
end usun_uzytkownik;
And the problem is that i'm using this code in another class and works good.
When i run it here i got an error:
