# 2893 Inserting or Updating Data in a BLOB Field Using Delphi 2009 Causes Data to be Unreadable

---

Since switching from Delphi 2007 to 2009 (using DBISAM 4.27 build 2) I get the error # 15002 (Error uncompressing data).

I use a local database with a table containing a compressed memo field.

When I compile my application with Delphi 2009, I get the error when navigation to a record that was inserted or edited with the Delphi 2009 version. Records inserted with the Delphi 2007 version of my app don't have this problem, also not with the Delphi 2009 version of my app.

I also tested to access a record that was changed or inserted under Delphi 2009 with the Delphi 2007 version of my application. In this case the error occurs.

It seems that the problem is posting a record under Delphi 2009.
