在兩個鏈接表的第二個表中創建行（通過fk鏈接）不起作用

Question

我正在使用Eclipse Juno，GWT，Java和MySQL。

我正在將行寫入兩個通過fk鏈接的表中。對第一個表的寫入工作正常。然後我從這個寫入中返回鍵（使用Statement.RETURN_GENERATED_KEYS）到下一個寫入。執行此寫操作時，出現錯誤「java.sql.SQLException：沒有爲參數1指定值」。我已經顯示了傳遞給每個參數的值，並且有值。

兩個表中的第一列是一個自動增量pk。第二個表中的第二列是fk。

該控制檯是（顯示在第一五行是被傳遞到的參數值和第一個是FK）：

cd_id = 6 
section = Cubs 
pack = Explorer 
start date = 2013-06-28 
end date = 2013-06-28

我希望得到任何幫助。問候，格林

Answer 1

ps應該ps2

ps2.setInt(1, cd_id); 
ps2.setString(2, section); 
ps2.setString(3, pack); 
ps2.setDate(4, (java.sql.Date) startDate); 
ps2.setDate(5, (java.sql.Date) endDate);
