Reading param context from an excel sheet

sszzxx — Fri, 11 Jan 2019 03:53:59 GMT

Hi All,

I have a job where it is taking 3 context param from an excel sheet:

1. .schema file

2. Data File

3. Output File

I was thinking if it's possible to take these 3 context from a .xls file as it is running for mutiple times.

The .xls file will have these information and there's like thousand over information and I do not want having to change the context_param manually each time.. :

Is there a way we can automate the job to take the context param from the excel sheet and run it?

SCHEMA	DATA_FILE	OUTPUT
I:\Schema\users.schema	I:\Data_File\users_data.txt	I:\Output\Output1.txt
I:\Schema\users1.schema	I:\Data_File\users1_data.txt	I:\Output\Output2.txt

Any help would be great, thanks.

generally - yes

variant 1 - read file with Input component and connect it to tFlowToIterate

tFlowToIterate automatically store each column to the global variable.

then do all other steps as iteration. You will have a loop for each row, on each iteration you can use correspondent values with (example) (String)globalMap.get("row1.SCHEMA")

variant 2 - same but with context variable. Little more complicated. You will need to create a loop for reading file row by row and store values to context variable from single row in the iteration. But variant 1 do absolutely same tasks
