Mapping - Adding conditions in tmap

Anonymous — Sat, 16 Nov 2024 14:11:58 GMT

Let us say Table1 (T1) has following columns
C1
C2
C3
C4
Table2 (T2) has following columns
C1
C2
C3
C4
I need to do a mapping and move C2, C3 and C4 from T2 to new table T3 only when T1.C1 == T2.C1 && T1.C2 == T2.C2 && T1.C3 == T2.C3
Please help

Well more simply

create output table in tMap and ad a filter (+->) with your condition

else you can use a triple inner join

Hello,
I want to put some condition in my tMap.
I have a tiFileInuptDelimited->tMap ->tPostgresqlOutput (my database is Postgres).
All my column in my File are string and I want to put some condition in my tMap to put my data in my table with Integer, Char, Date, etc....
So for the Date, I have a regex expression in my condition and in the expression of my field I am using TalendDate.parseDate ("dd/MM/yyyy", row1.date). So it works when my data of my File is not empty because othwersie it doesn't work.
I tried to put another condition (String.valueOf(row1.date).equals("")) but i have still the same error message:
Caused by: java.text.ParseException: Unparseable date: ""
at java.text.DateFormat.parse(DateFormat.java:335)
at routines.TalendDate.parseDate(TalendDate.java:85)
... 3 more
I also have tried to put String.valueOf(row1;date)==null and i don't have an error but that doesn't go to the database.....
And i have the same rpoblem when i want to parse the String in an Integer....
with Integer.parseInt
thank you for your help

if you have a new/different question, post it in its own topic (makes it easier 1. for people to realize you have a new question. 2. see that your question has not already been answered), like you did later yesterday: 4655
also, don't post the same question in multiple topics

Hi,
I want to create a condition in the Talend TMap, here's what I do: when the value in the Code column of the table source = "W" in the attribute table CodeDisplay the destination, I would like to display "Woman" and if I find "M" I put "Man" here's what I have but it does not work:
row1.code.equals ("W")? "Woman": "Man"
I tried that too:
row1.code.equals ('W')? "Woman", "Man" / / simple coat with ''
Is what we can put together three alternatives for example:
if it is equal to 'W' to women, if it is equal to "M" to "Man", and if it is not W or M, to "Undefined"
Could you help me please?
Here is the error that appears:

Hi,

if it is equal to 'W' to women, if it is equal to "M" to "Man", and if it is not W or M, to "Undefined"
Could you help me please?

The expression as below should work:
row1.code.equals("W")?"Woman" row1.code.equals("M")?"Man":undefined")

This is another problem, the class file is missing, I think you could get the same problem on other jobs.
Which OS? Do you have blank space in the installation path?
