Hi,

SELECT *

FROM TABLE

WHERE ID = (SELECT MAX(ID) FROM TABLE)

What does your table structure look like? Do you have a naturally

increasing column (DATETIME reflecting when the row was

created)?

Regards

Sandeep

Thanks so much for your replies!!

But, my table have only one column, the table structure look like --

Create table latest_value

(

[name] varchar(50)

)

Hi Vijay,

The concern is, unless you have any one of the column like identity, date of creating/modify, or row version (timestamp), it’s very difficult/can’t to get the last insert row from the table.

And have the question; you have any audit for that table?

You could create an insert trigger that puts the value NAME into another table. It would overwrite whatever the previous value was with the new value. Or add a new unique column to your table.

If your table lacks a key then obviously you ought to add one at the first opportunity, otherwise it could be difficult to make any sense of the results. Why would you want duplicate rows in the table?

There is not necessarily any single latest row because multiple rows could have been inserted simultaneously.

In SQL Server 2008 and later you can turn on the Change Data Capture feature so that you can retrieve information about the row insertion order. In earlier versions that information is not exposed unless you record it in the database yourself.

Without either a date column or and identity column, it can't be done reliably. As David suggests, you should probably add one, the other, or perhaps both.

That does NOT get you what you want, which is the last row inserted into the main production table. That gets you the 'last' row inserted into the TEMPORARY table. Tables are UNORDERED sets of data unless they have a CLUSTERED INDEX on them. SQL Server can insert the rows from the production table into the temp table in ANY ORDER IT PLEASES, and that order can change from execution to execution. You cannot rely on this method.

The last value inserted into your table was 'Snoopy'. Prove me wrong.

Seriously, without a date/time column, or at least a sequential identifier, there is no deterministic way to know which value was inserted last. Still there are ways to have a clue.

For example, you could query the default trace for the last INSERT on the table, but that won't work if the table is BULK inserted.

http://www.sqlservercentral.com/articles/SQL+Server+2005/64547/

Also, you could also create an AFTER INSERT trigger on the table which updates the inserted value in another table each time an insert is performed, but again that won't work for BULK inserts.

Tables are UNORDERED sets of data unless they have a CLUSTERED INDEX on them.

Tables are unordered sets even if they do have a clustered index. A clustered index is just one form of internal storage. It doesn't impose any logical ordering any more than a nonclustered index on a heap does.

Heh... obviously not a fan of WITH (INDEX(0)) or the "Quirky" Update, huh?

WITH (INDEX(0)) doesn't mean a table is ordered. It just specifies a hint for an execution plan. In fact it doesn't even order the query results AFAIK because the INDEX hint without ORDER BY results in an unordered scan. Rows might be returned in allocation order rather than cluster key order or they might be reordered by a merry-go-round scan.

The order in which records are inserted does not hold any significance unless you specifically track the insert time details.

Also the order in which records are stored does not hold any significance in the table if you do not have clustered index or auto increment or ordered data.

Just to make sure we completely cover the topic:

An IDENTITY column will help you find the most recently-inserted row, unless IDENTITY_INSERT or DBCC CHECKIDENT (RESEED) are used to insert records out of order.

A TIMESTAMP column will allow you to find the row used in the most recent INSERT or UPDATE.

A DATETIME column with DEFAULT GETDATE() will work for single-row inserts, but if multiple rows are inserted in the same statement they will all have the same value.
