I have a situation in which I have a column with descriptions, the problem is that if any of the special characters (that is any character other than 0 to 9, a to z , A to Z) are contained in it. I want to mark it.
The problem is tried looping through each value character by character , it becomes too much time taking. I have about 20K values.
I want mark
All suggestion and help much appreciated , Especially from
