I converted a table's DateTime field to DateTimeOffset, but now the offset is automatically set to +00:00.
I need to change all DateTimeOffset fields of this table to an offset of +1:00.
How can I do this in an update query?

To get the last updated record in SQL Server: We can write trigger (which automatically fires) i.e. whenever there is a change (update) that occurs on a row, the “lastupdatedby” column value should get updated by the current timestamp.
Null Values can be replaced in SQL by using UPDATE, SET, and WHERE to search a column in a table for nulls and replace them.
To modify a primary key Open the Table Designer for the table whose primary key you want to modify, right-click in the Table Designer, and choose Indexes/Keys from the shortcut menu. In the Indexes/Keys dialog box, select the primary key index from the Selected Primary/Unique Key or Index list.
You can use SWITCHOFFSET to change the offset. You will need to subtract the amount of hours though from the date if you don't want the date to change.
SELECT SWITCHOFFSET(DATEADD(hh, -1, CAST (GETDATE() AS DATETIMEOFFSET)),
'+01:00')
You can use TODATETIMEOFFSET(datetime, '+01:00' ) This wont affect the datetime part.
