Dear EveryOne,
sorry if my question has already been answered - I didn't find anything relevant. I have a query with a between operator on a non-indexed varchar(30) field - currently on FB 2.5 : . where MYFIELD between 'AHH00091/2017' and 'AHH00141/2017' I would expect 51 records from 91 to 141 all ending with /2017 but surprisingly, records ending with /2016 or /2015, etc. also appear in the resultset ( so I have to put other criteria e.g. and MYFIELD like '%/2017' ) I even added and index on the corresponding field but the result was the same : ( I also tested with Firebird 3 all above tests with the same result : ( Is there a size limit (count of relevant characters) on between comparisons? Am I missing something? Thank you. Best regards, Tamas Kiss
