Hi.
For your particular case you do not need regex at all. Simple substring +
position.
Example:
Select
D.NAZWA
, SUBSTRING(D.NAZWA FROM POSITION('V', D.NAZWA)+1 FOR POSITION('p', D.NAZWA)-3)
AS V
, SUBSTRING(D.NAZWA FROM POSITION('p', D.NAZWA)+1 FOR POSITION(' ',
SUBSTRING(D.NAZWA FROM

I just noticed that it is safer to use 'V#"[[:DIGIT:]]+#" %.pdf'

You could use "Regular
I have some data in a table which I need to 'pull apart'. It's
essentially a ID for a reference but it's not as tidy as I would like
because of the variable length and a little variable in case although
the format is consistent.
V p .pdf
For example 'V12 p234 The state of the nation.pdf'
