Select by Attributes With OR Operator












2















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 "="?



Thanks in advance

          You should repeat the column name for each value in the query



          "H1" = '31p' or "H1" = '34n' ...


          You had better to use "in" operator like



          "H1" in ('31p', '34n', '31q', '61f')
