Hi Everyone,
Can we use substring function in a filter.
Like in transformer column_name[1,6] = 7777
Can we do the same in a filter? If yes what is the syntax
Thanks in advance.

I do not think that is possible in a filter stage. The filter stage only filters records, unmodified.

One task, one stage.
The Filter stage filters.
If you need substring perform that in an upstream Modify or Transformer stage.

Is it possible to then do something like a SQL "LIKE" command?

The filter option is calling an external command/script/program on the operating system. Therefore, you have whatever functionality is provided within that command/script/program.

I'm not seeing where it says stage vs. seq. file option. vs. coffee, etc.
