I have a SQLDataSet that I'm using thus: if (rdByApplID.Checked ) then if (length(lc_appl_id) > 0) then begin dsFindApplicant.CommandText := 'select * from ps_applicant where appl_id = :pappl_id'; dsFindApplicant.ParamByName('pappl_id').AsString := lc_appl_id; end; when executed was getting the following message: "dsFindApplicant: parameter 'pappl_id' not found" However, when I provided the value directly as shown below, it ran sucessfully. if (rdByApplID.Checked ) then if (length(lc_appl_id) > 0) then begin dsFindApplicant.CommandText := 'select * from ps_applicant where appl_id = ' + '''' + lc_appl_id + ''''; end; Setting the parameter of the component at the design time did not work either. I would like to provide different parameter in my code in the where clause. Your help will be greatly appreciated. Thanks.

I'm O.K., you don't have to respond to it. Thanks. Gbenga "Gbenga Abimbola" <gabimbola (AT) columbus (DOT) gov> wrote: Quote: Hi: Using dbExpress.
