Hello!
So, I wanna check if my column X contains the string "CB" or "CL" or "CV", and if it does, I want to change all the null fields to the corresponding string "CB" or "CL" or "CV". For example, if the column X contains "CV" in a field, all the null values of that column will turn into "CV". And don´t worry, there will be never CB or CL or CV in the same column.
Thanks for any help,
Fernando S.
