Format Date

[talendstar]

I am passing a date value to a global variable and then trying to print it to the screen using tJavaRow:

System.out.println(globalMap.get("MaxInsertDateTime"));

and this prints fine - here is the output:

2019-07-15T03:46:02

However what I would like to do is format the value to "YYYY-MM-DD" format. I tried multiple different ways to do it but no luck so far:

System.out.println(TalendDate.formatDate("YYYY-MM-DD",(globalMap.get("MaxInsertDateTime"))));

Error:

Detail Message: The method formatDate(String, Date) in the type TalendDate is not applicable for the arguments (String, Object)

I also tried this:

System.out.println((String)globalMap.get("MaxInsertDateTime"));

Error:

java.lang.ClassCastException: java.util.Date cannot be cast to java.lang.String

What am I doing wrong here?

My goal is to format the date as "YYYY-MM-DD" and then use it later in tMSSQLInput component in a where condition.

Hi,

The message is telling you what's wrong :

The method formatDate(String, Date) in the type TalendDate is not applicable for the arguments (String, Object)

Java doesn't know that your globalMap.get("MaxInsertDateTime") object is actually a date, so it takes it as an Object and cannot use formatDate on an Object.

You have to explicitly tell that globalMap.get("MaxInsertDateTime") is a Date (assuming it *is* a date of course).

If you setup your global variable correctly, this should work :

System.out.println(TalendDate.formatDate("yyyy-MM-dd",(Date)globalMap.get("MaxInsertDateTime")));

btw: Talend corrects the misuse of upper/lower case in the date format but I strongly suggest you to use the proper case (see SimpleDateFormat for the detail)
