Load value dynamically to tSampleRow

Anonymous — Sat, 16 Nov 2024 08:28:14 GMT

I have a input file with 10 columns and a simple tmap which process the 10 columns and send it to tSampleRow where i hardcoded and to output file. It works fine.

Now i need to change the value of tSampleRow dynamically ( fetch value from database and set in context variable) and use the context variable in tSampleRow.

1. Job

2. ChildJob ( for loading context variable ) which works fine

3. tRunJob

4. tSampleRow

Can you help me how to give the value in tSampleRow and What should i assign in tRunJob Context column.

Child Job works fine :

System.out.println("hi");

System.out.println(context.rows);

globalMap.put("output",context.rows);

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

Starting job DatabaseJob at 15:32 03/04/2018.

[statistics] connecting to socket on port 3705
[statistics] connected
tContextLoad_4 set key "days" with value "monday"
tContextLoad_4 set key "rows" with value "5"
hi

5
[statistics] disconnected
Job DatabaseJob ended at 15:32 03/04/2018. [exit code=0]

Hi Dinesh,

Are you looking for this ?

You need to define context value in DB. like key=rows and value=1..5

assign this using context load in job and use context.rows in tSampleRow.
