Please help me with this.
Hi Lily, please find the solution below:
You can cast any (column's) data type to string data type with the following processors:
1. Processor Name : Cast to Single type
Select single or multiple columns to which you want to cast single data type.
Select new data type for selected columns.
2. Processor Name : Cast to Different type
Want to cast different column to different cast type.
Select column then select data type and replace old column as true.
Hope, it will help you.
