I have the atttribute table with the values like these:


I would like to get rid of the ', although the regular formula for the replace seems not to work


Is there any other way to get rid of the apostrophe mark?

    you'll need to escape the middle ' - I forget what the escape char is for those expressions try \\'

  • Why use regexp_replace rather than a simple replace ? anyway in both case you will need to escape the quote by doubling it so use regexp_replace("STREET",'''','') or replace("STREET",'''','')

    Also note that unless you use a more complex expression in your regex_replace this will also remove legitimate quote if present (ie. it will turn 'O'Hare International Airport' to OHare International Airport)

Use this: replace (STREET, '''','')

Variant: to remove only single quotes ' at the start and end and keep them inside the string (O'Hare International Airport, see comment by @J.R), use:

regexp_replace (STREET,'^''|''$','')

'O'Hare International Airport' -> O'Hare International Airport

In RegEx, ^ stands for start, $ for end of line, see here. The pipe | is a logical OR operator.
