I have tried like this (Delphi), but it does not work: var StartDate, EndDate: TDate; .... SQL.Add('AND (Invoices.DateTimeStamp BETWEEN :Start AND :End)'); Params.CreateParam(ftTimeStamp,'Start',ptInput).AsSQLTimeStamp := DateTimeToSQLTimeStamp(StartDate); Params.CreateParam(ftTimeStamp,'End',ptInput).AsSQLTimeStamp := DateTimeToSQLTimeStamp(EndDate); .... I badly want to be free of text conversions (done at the current time) if it is possible. I am sure it is, but how? -- Best Regards / Med venlig hilsen, Nenad Blagojevic [email]n.blagojevic (AT) techotel (DOT) dk[/email] AK Techotel A/S Sandager 8 DK 2605 Brøndby tel +45 3646 1155 dir. +45 3619 2143 Back to top Wayne Niddery [TeamB] Guest Posted: Tue Nov 18, 2003 4:35 pm    Post subject: Re: SQL and date parameters Nenad Blagojevic wrote: Quote: How should parameters being used in dbexpress TSQLQuery components?

The parameters are created for you after assigning the SQL text.
