ORA-00932试图克服变异表错误
|
我已经应用了有关如何克服变异表错误的说明：
http://asktom.oracle.com/pls/asktom/ASKTOM.download_file?p_file=6551198119097816936
但是在最后一个触发器中，我得到了一个轻松的错误：
SQL> create or replace trigger Factura_Detalle_ai
after insert or update of PRODUCTO on Factura_Detalle
begin
for i in 1 .. state_pkg.newRows.count loop
UPDATE Factura_Detalle
SET Precio = (SELECT pre.PRECIO
FROM PRECIO pre
WHERE pre.PRODUCTO = state_pkg.newRows(i));
end loop;
end;
/

ROWID是每行地址的伪列，它是一种数据类型。 编辑： 也许是这样的：UPDATE Factura_Detalle SET Precio = ( SELECT pre.PRECIO FROM PRECIO pre WHERE pre.PRODUCTO = Factura_Detalle.PRODUCTO ) WHERE ROWID = state_pkg.newRows(i);
