I know this is a very basic question, but I've been looking for an answer and haven't been able to find one, so here it goes. I am trying to build a long query to select features that have different values in the same field, in order to make it as agile as poossible. All in one selection.
Example: In a given attribute table, in the field "H1" select features that have values "31p", "34n", "61f" and "31q" in it.
"H1" = '31p' OR '34n' OR '61f' OR '31q' "H1" = '31p' OR "H1" = '34n' OR "H1" = '61f' OR = '31q'
None of them work. Should I use "IS" logical operator instead of "="?
