I have a trigger,
But am having a problem updating the comp_notmaintained value as its of type ntext.
If I remove this value it works with the other two.

Please can anyone suggest a workaround?

Many thanks,

Mim
CREATE trigger [trg_updatecomp]
  on [dbo].[Installed]
 for update
as
  update Company
    set comp_inststatus
      = i.inst_status, comp_expirydate = i.inst_expirydate, comp_notmaintained = i.inst_notmaintained
from Installed q 
join inserted i
on i.inst_companyid = q.inst_companyid

you cannot update the text column with an update statement, you need to use UPDATETEXT /WRITETEXT

If you are using SQL Server 2005 or later, use nvarchar(max) instead of ntext.

This should work:

CREATE TRIGGER [trg_updatecomp]
  ON [dbo].[Installed]
 FOR UPDATE
AS
  UPDATE Company
    SET comp_inststatus
      = i.inst_status, comp_expirydate = i.inst_expirydate, comp_notmaintained = q.inst_notmaintained
  FROM Installed q
  JOIN inserted i
  ON i.inst_companyid = q.inst_companyid
  JOIN Company
  ON i.inst_companyid = Company.inst_companyid ;
GO
