Hi !
My problem can appear easy, but I'm working on it for two hours and I didn't find any solution...
I want to create a column in a table. This is a code, composed with exactly 5 numbers.
At the beggining, I used a numeric column, but if I do it, zeros are erased at beginning of code.And now, with a text one, I don't know how to check if all characters are numbers.
So, what should I do ???
