I have a table which is about 2G size. the lock type on this table is set as AllPage. I think this cause performance issue when issue select query, many SH lock applied. I try to change the lock type to datarow, which should have no lock when issue select as document indicated.
but when I try it with DBArtisan, it took longtime and never end. Then I stop the app and connect it again. I found the lock type do change it to datarow. but there is a new table name like mytab_3309ac22 created.
then I try to change lock type again on other table and got following info:
You can not run Alter Table Lock in this database because the 'select into/bulkcopy' option is off.
Looks like dboption changed. So want to know if this is safe for data when change lock type? how to ensure it is done properly?
