// MSSQL returns dates with the format Oct 13 2002 or 13 Oct 2002
|
|
// and this causes tons of problems because localized versions of
|
|
// MSSQL will return the dates in dmy or mdy order; and also the
|
|
// month strings depends on what language has been configured. The
|
|
// following two variables allow you to control the localization
|
|
// settings - Ugh.
|
|
//
|
|
// MORE LOCALIZATION INFO
|
|
// ----------------------
|
|
// To configure datetime, look for and modify sqlcommn.loc,
|
|
// typically found in c:\mssql\install
|
|
// Also read :
|
|
// http://support.microsoft.com/default.aspx?scid=kb;EN-US;q220918
|
|
// Alternatively use:
|
|
// CONVERT(char(12),datecol,120)
|
|
//
|
|
// Also if your month is showing as month-1,
|
|
// e.g. Jan 13, 2002 is showing as 13/0/2002, then see
|
|
// http://phplens.com/lens/lensforum/msgs.php?id=7048&x=1
