How to set the variable of read column?

How to set the variable of read column if the value are string?

Hi @fightblue,
Could you please elaborate it.

i use Ctrl+K to creat variable which shows object
I want to know is there any other variable to use, and if i can clear it

Instead of creating ctrl+k , create own variable and change the variable type also
“Browse for type”

Hi @fightblue

i just converted IEnumerable object to String.


thanks. how to clear ColumaA, because it will be used repeatly, i want to clear it before be used again.
