Informatica中日期数据类型的问题

Question

I created a reusable transformation in which I have an input port of date/time format.

Now when I use this date/time port in my java code it gives me incompatible error long/date.

So I changed the input port of java transformation to String and used this string variable in java transformation. But even this code is giving me an error.

Day is an output port of type String. The below is the code used in java transformation:

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);

Please let me know how to use date/time variable in java transformation.

Regards, Dex.

Answer 1

You should use an expression transformation with the expression TO_CHAR(inp_Date,'dd') to do such conversions.

In your Java code the format string (dd-MM-yyyy) does not match the input date format (05/06/1998 00:00:00.000000). It should probably be changed to something like this:

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