问题 I know the title may seem strange but this is what I want to do: I have table with many records. I want to get some of this records and insert them in other table. Something like this: INSERT INTO TableNew SELECT * FROM TableOld WHERE ... The tricky part is that I want this rows that I have inserted to be deleted form the origin table as well. Is there a easy way to do this, because the only think that I have managed to do is to use a temporary table for saving the selected records and then

问题 In SQL Server I need to find the offset of a given datetimeoffset(7) . I have researched the documentation and there are all ways to change the offset but not a way to know the offset of a particular value (sorry if I missed it). Well I came up with the following piece of code that I find too complicated although seems to work. DECLARE @datetimeOffset datetimeoffset(7) SET @datetimeOffset = CAST('2007-05-08 22:35:29.1234567-05:00' AS datetimeoffset(7)) DECLARE @result datetimeoffset(7)

问题 I've made some research on the matter but don't have solution yet. What I want to get is column-level dependencies in a view. So, let's say we have a table like this create table TEST( first_name varchar(10), last_name varchar(10), street varchar(10), number int ) and a view like this: create view vTEST as select first_name + ' ' + last_name as [name], street + ' ' + cast(number as varchar(max)) as [address] from dbo.TEST What I'd like is to get result like this: column_name depends_on_column

问题 I have recently done some archiving of my data, and performed the following: I had a database table that had over 33 million records, many of which were duplicates. I backed up the table and inserted the unique data into a new table, then renamed/swapped the table names, this achieved what I needed. Now however I am left with two tables... Table1 (good/live table) - 10 million records Table1_Backup (backup table) - 33 million records After doing this my SQL mdf/data file has rose to 319.7 GB,

问题 I'm in a weird situation with my query. My objective is to display the total deposits and withdrawals from multiple transactions for each person and display them.
