Re: QRY and Dates

There is a special variable for current date, so that is easy. The trick is converting your field into a date string representation. This means inserting dashes between the year and month and day, since SQL does not recognize just the digits as a valid string representation. (See the SQL Reference section on string representations of dates and times.)
If it is a character field, then do this, using an ISO representation - no need to convert explicitly to a date: 

select * from yourfile
where substr(datefld,1,4) || '-' || substr(datefld,5,2) || '-' || substr(datefld,7,2) >= 
current date - 1 day

If the date field is numeric with 8 digits, use

digits(datefld) where I have "datefld" in the example.

Hi, I've got a file containing dates in yyyymmdd format. The date contains entries that are about a year old. I want to use query, if possible, to report on records where the dates are the current date or the current date -1 (yesterday). 

Does anyone have any examples of how this can be done?

Any help appreciated.

Thanks
