Do not Filter "_" as a placeholder, but as real sign

Hi @all,

i want to Filter “_” as a real sign, not as a wildcart or placeholder.

For example…

What can I do?

Thx

Hi @StevenB,

thank you for raising that question!

Wildcards can be escaped with a backslash ( ‘%’ , ‘_’). You will find further information regarding how to use wildcards in the PQL Function Library. Simply search for ‘wildcard’.

You can access the PQL Function Library via the help button in your analysis.

Hopefully that will solve your issue!

Best,

Justin

Thank yor for your answer, but the problem is still alive.

For Example:

Result:

With the backslash I still have the wrong lines in the evaluation.

I need all lines with _B_

Hi Steven,

when you’re using a string constant as a pattern, you need to escape the backslash itself.
The pattern would therefore be ‘%\\_B\\_%’

Hope this fixes the issue!

Best
David
