BDE TQuery reading a SQL Server VarChar(500)


I have a Table on SQL Server having a VarChar(500) field.  When I query this table using a TQuery component, it only returns the first 255 characters from the 500 char field.

I tried the same thing with TADOQuery object and it worked fine, all 500 char were returned.

I HAVE to use a TQuery object (I cannot switch to a TADOQuery).

Can anyone help me with this ?

Thanks :)

   The problem came from MS side, BDE uses DBLibrary for accessing Sql server, and MS didn't update the DBLibrary for sql server 7 and above to allow the new data types and varchar > 255

to solve this problem you need to switch to ADO

BTW, there's area of Delphi topic, if you ask the question there you will got a better and more comments for your questions

with the same problem, my solution
   WHEN len(texte) > 255 THEN substring(texte,1,255)
   ELSE texte
END as texte1,
   WHEN len(texte) > 255 THEN substring(texte,255,len(texte)-255)
   ELSE ''
END as texte2

After in the program, Query.FieldByName('texte1').AsString + Query.FieldByName('texte2').AsString
