Using QGIS in the operation 'select by expression' how is the correct expression to select multiple field value? ex. City NAME = ROME and NAPLES (expression is invalid)

    do you mean OR instead of AND?

You can also use the SQL IN operator

"City Name" IN ('ROME','NAPLES')
  • Is it possible to do something similar but only stating part of the part of the words ? For example i would like to select all features containing 'RO' and 'PLES'. I tried IN but it doesn't works. I know that "City Name" LIKE '%RO%' OR "City Name" LIKE '%PLES%' works but the expression is a bit long... I would like something such as "City Name" LIKE ('%RO%','%PLES%').

Do you mean:

"City Name" = 'ROME' OR "City Name" = 'NAPLES' OR ....
  • Just formatted the code so that it's valid QGIS expression code.

    This won't actually return any results. As the City Name can't both be ROME and Naples. You want an or here, or use flippinGeo's answer and use "IN".

  • That's right, my mistake, you need to use OR, rather than AND Nov 21 '13 at 5:03
