Re: send data one after another to three tables in cyclic order

Hi,

 

In tmysqlinput, add an additional column to group the data into different buckets.

e.g:- 

select (@a:=@a+1)%300 bucket, emp_id from employee, (SELECT @a:= 0) AS a order by emp_id;

 

You need to add a tmap after tmysqlinput and connect 3 tmysqloutputs as 3 output components of tmap.

 

For the first output table in tamp, add a condition in expression filter input_row.bucket>=1 && input_row.bucket<=100

 

Similarly, for second output table,add expression     input_row.bucket>=101 && input_row.bucket<=200

 

For third output table, (input_row.bucket>=201 && input_row.bucket<=299) ||  input_row.bucket == 0  

Please note that in third output table, you will have an additional clause to capture records with numbers like like 300, 600, 900 etc.

 

This should resolve your issue.

 

Please mark it as an acceptable solution if the suggestion has helped to resolve your query.

 

Warm Regards,
