Exclude expressions for defining a role

Dear all,


I would like to define roles, but unfortunately I do not know the needed expression.

I do have a column “PLP”, containing several correct entries, but sometimes it is just mentioned “not defined” or the line is empty.


Now I would like to exclude the empty ones as well as the ones stating “not defined”…


I already have several roles in place, but these do never exclude something, but just search for something specific.


Is there anybody out there who could help me, please?

Hi @Orstenpowers ,


Not very clear.


What is the expected output. A table, a column.


You can use  the EXCEPT function

@Orstenpowers , Not very clear. In edit query mode you can replace null value with other values

Hi, I am trying to define/ manage roles




I thought of something like

[PLP] <> "not defined" && [PLP] <> blank

but this does not work. 

How do I need to adjust this to work properly? Can you help me?

I got it on my own. 🙂


[PLP] <> BLANK() &&
[PLP] <> "not defined"


Thanks for your offered support!
