Problem with a field of type varchar(4000) and TZQuery

[borelló]

I have a problem that I don't know how to resolve:

I'm using a TZQuery inside a class. I have created this TZQuery dinamically to access a table (in a MSSQL Server) that has a field of type varchar(4000). The result of the query for this field is a string of 256 characters long. So my trouble is that there are values for this field longer than 256 characters, and I can`t modify the database.

How could I resolve this problem?

I'm working with Delphi 7 and MSSQL Server 2000.

Sorry for my english, It isn't my native language.
