Re: Selecting rows by DATE ranges
date(), date_format() t Miguel Cardenas írta: Hello list I found a little problem with an application am developing, in particular creating reports by DATE ranges. Examples: select ... where date>"2007-01-01"; returns all records where date is greater (and equal inclusive) to 2007-01-01 select ... where date>="2007-01-01"; returns all records where date is greater/equal to 2007-01-01 the ">" and ">=" have the same effect select ... where date>"2007-01-01" and date<"2007-01-20"; returns all records where date is greater/equal to 2007-01-01 and less than "2007-01-20" *** DOES NOT RETURN RECORDS FROM DAY *20* select ... where date>"2007-01-01" and date<="2007-01-20"; returns all records where date is greater/equal to 2007-01-01 and less than "2007-01-20" although I'm using "<=" *** DOES NOT RETURN RECORDS FROM DAY *20* My doubts are: 1. how can I retrieve rows with a date>"..." NOT INCLUDING the day of the specified date, I mean apply a strict GREATHER THAN 2. how can I retrieve rows with date<="..."

Accented characters in InnoDB tables?
Do you have to do something special with InnoDB tables to accept various character sets like accented, European characters? Using the default, these accented characters come out as garbage. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
