There is a table with trigger in our SQL database. (sql server 2014). When updating record from Microsoft SQL Server Management Studio update takes like 1/10 sec. When the record is changed in MS ACCESS (in the form) it takes like 5-6 seconds to update. There is a trigger on that table, but the same operation directly from MSS Management Studio is fast, so it is not a problem with a trigger itself. THe trigger has to insert 1 record to 15 milion records table. I am looking for reasons why the same operation from ACCESS and SQL management studio can take 40 times longer. Any suggestions? Or links to known issues in that topic?
EDIT: It's ACCESS 2003. It's subform bound to form by ID field. I am edditing simple integer column of record. I use normal connection with my sql server, it's adp project and we just use typical connection for it. I tried to do update from VBA (the same project) but from simple module -> the same effect. So it does not metter if it is eddited from form or update command is send from other module to that table. It still takes long.
