Informatica中日期數據類型的問題

Question

我創建了一個可重用的轉換，其中有一個日期/時間格式的輸入端口。

現在，當我在Java代碼中使用此日期/時間端口時，它給了我不兼容的錯誤long / date。

因此，我將java轉換的輸入端口更改為String，並在java轉換中使用了此字符串變量。 但是，即使這段代碼也給了我一個錯誤。

Day是String類型的輸出端口。 以下是java轉換中使用的代碼：

SimpleDateFormat formatter;
formatter = new SimpleDateFormat("dd-MM-yyyy");
Date my_date = null;
try{
    my_date = formatter.parse(Inp_Date);
}
catch(Exception e) { 
          System.out.println("Unparseable using " + formatter); 
      }
    formatter = new SimpleDateFormat("d");
    Day=formatter.format(my_date);

請讓我知道如何在java轉換中使用日期/時間變量。

問候，敏捷。

Answer 1

您應該使用帶有表達式TO_CHAR(inp_Date,'dd')的表達式TO_CHAR(inp_Date,'dd')來進行此類轉換。

在您的Java代碼中，格式字符串（dd-MM-yyyy）與輸入日期格式（05/06/1998 00：00：00.000000）不匹配。 應該將其更改為以下內容：

formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss.SSSSSS");
