问题 I am trying to find the smallest missing number in this table. +------+--------+ | id | number | +------+--------+ | 902 | 1 | | 908 | 2 | | 1007 | 7 | | 1189 | 8 | | 1233 | 12 | | 1757 | 15 | +------+--------+ In the number column, you can see there are several gaps between the numbers. I need to get the number after the smallest gap. So in the case above I need the number 3.

问题 I have SQL Server 2014 and I'm trying to access my reports via the URL access. As I understand, the Excel format should be giving me an XLSX file which supports an unlimited number of rows. However, after looking at my log files I noticed that I was getting maximum row errors for any reports with more then 65536 rows. After looking into this I discovered that any time I request the reports via URL with format as EXCEL, they generate a XLS file instead of XLSX. If I run the reports out of

问题 Does a query that gets the count of all rows in a table have to do a full table scan or does SQL Server maintain a count of rows somewhere? SELECT COUNT(*) FROM TABLE_NAME; The table TABLE_NAME has a primary key, and therefore a clustered index, and looks like so: CREATE TABLE TABLE_NAME ( Id int PRIMARY KEY IDENTITY(1, 1), Name nvarchar(50) NOT NULL ); I am using Microsoft SQL Server 2014. 回答1: The server will always read all records (if there's an index then it will scan the entire index)

问题 Envision a stored procedure which takes @skip (offset) and @take (maximum number of rows to return. If @take is null , then I want to return "all rows after applying the offset". I can accomplish this by counting the number of rows in the table/view if @take is null , but then I have to perform two queries which is, of course, not optimal. I was hoping there was an option similar to FETCH [NEXT] ALL ROWS . DECLARE @skip BIGINT = 0; DECLARE @take BIGINT = NULL; IF (@take IS NULL) SET @take =

问题 Concerning SQL Server Change Data Capture , can you track the User who has made the change to the row/column data or is there anyway to extend CDC to allow this? I couldn't see anything in the documentation. 回答1: You can't capture username with CDC.. You have to use Auditing to do so or if this is a one time request,you can query TLOG.. Below is the connect item requesting the same.. CDC : options to capture more data (username, date/time, etc) You also can use triggers as per this article

问题 I want save date with UTC time zone in sql server 2014. I have used ZonedDateTime zonedDateTime = ZonedDateTime.now(ZoneId.of("UTC")) to get the current date time and persisting this to db using Hibernate session object.

问题 Given this code, I'm getting back no results: SELECT TOP 10 * FROM MyTable WHERE CONTAINS(TextColumn, '"W"') Things I've checked: Longer words return a result There are no stop LIST associated with this index There is definitely text such as "James W Brown" in the column The full text index is up to date. EDIT: I was looking for a stop lists, not a stop word, associated with the index. 回答1: The answer is to make sure you have an empty stop list associated with the index. It isn't enough to
