Hi lortega,

Label1.Caption := Table1.FieldByName('Date').AsString;
or
Label1.Caption := Table1.FieldByName('Date').AsInteger;
or
.

hi Iortega,

try to put the name of the field in double-quotes e.g. select "Date" from ... or if you are working with an SQL-Server: select tablename.Fieldname from ...

I need something like...

Select * from myTable Where Date = '8/4/98'

where Date is the name of the field...

note on Oracle or MSSQL you should write the fieldname between brackets  []...
Select * from myTable Where [Date] = '8/4/98'

but who to do this on Delphi (TQuery)?

Select * from myTable Where "Date" = '8/4/98'    // Don't work

Changing the fieldname is not an option I suppose?

I use dates with a prefix:

Arrival_Date
Depart_Date
Trace_Date
Action_Date
Orig_Date
etc.

hi Iortega,

I tried to write a little bit code concerning your problem and found the following result:

with this sql-statement select * from "f:\pdoxdb\test" where "date" ="" everything is allright (concering the date field). the only thing you must pay attention (for correct results) is the format of your date-field! this belongs to your database-type. e.g. some databases use an internal date format and so you have to cast your input date (10.10.98) to this internal format (sometimes) - so please be careful.

hi Iortega,

very strange field-format, isn't it ???? Try to find the one who defined the database structure and the field-formats and buy him a lollypop ... :-)))

Do you leave the format unchanged or will you change it??? If you leave the format there should be a format-procedure which should insure an everytimes equal format result before writing to the database except you will sooner or later run into troubles (inconsitency or wrong search results) !!!
