FOR EACH ROW triggers are called once for each inserted, updated, or deleted row.QUEUE is implemented for syntax compatibility with HSQL and has no effect.The trigger need to be created in the same schema as the table. Currently, enabling this is experimental only.This is a global setting, which means it is not possible to open multiple databases with different modes at the same time in the same virtual machine

SQL Server Forums - How to change Increment Value on IDENTITY column
That's not a problem, easily scripted (although we have to make sure we have conditionally scripted all possible FKeys for all databases (one per client).There are not many rows (yet!)Half a dozen client databases have this issue in production. So if we have added (accidentally or deliberately) an additional FKey - perhaps to a client-specific table - then the script would fail.Probably some other things that I've overlooked ..

Instead, Enterprise Manager creates a new table that has the new schema with the changed nullability setting, uses an INSERT INTO statement to move the data into the new table, then deletes the old table. If you use SQL Server Profiler to trace the activity of Enterprise Manager, you'll see that Enterprise Manager can issue more than 150 commands that change the nullability of a column
The orders in which these are executed are as follows: Table Functions Unique Constraints Check Constraints Indexes You must also edit this script to use your desired collation. Download all scripts and explanation here About Collation Consolidation At some time in your DBA career, you may find yourself in a position when you sit back and realize that your database collations have somehow run amuck, or are faced with the ever annoying CANNOT RESOLVE COLLATION message when trying to join data of varying collation settings
sql server - Why does ALTER COLUMN to NOT NULL cause massive log file growth? - Database Administrators Stack Exchange
But it's clear that - while both the update operation and the addition of the NOT NULL constraint undeniably write to the page - the latter does so in an entirely different way. On databases with one of the snapshot isolation options enabled then the versioning information in each row is updated (@SQL Kiwi points out that this can also occur in databases without SI enabled as described here)
I changed the database collation to the correct one and when I ran the process it created a new database and assigned the default (correct) collation to all the columns. If you have any good idea about this subject, I encourage you to write down good small post about the subject and I publish as blog post with due credit to you along with your contact info
alter table - SQL Server - script to update database columns from varchar to nvarchar if not already nvarchar - Stack Overflow
