Sql updating a table from itself
Table variable instances of those are different in many respects to the ones discussed below! NB: Within stored routines both types of object can be cached rather than repeatedly creating and dropping new tables.
There are restrictions on when this caching can occur however that are possible to violate for function does not work and the internal name is entirely system generated with no relationship to the variable name.
The below demonstrates the metadata is still there however by keying in on a (hopefully unique) column name.
For tables without unique column names the object_id can be determined using 0), B INT DEFAULT 1, In Row Filler char(1000) DEFAULT REPLICATE('A',1000), Off Row Filler varchar(8000) DEFAULT REPLICATE('B',8000), LOBFiller varchar(max) DEFAULT REPLICATE(cast('C' as varchar(max)),10000), UNIQUE CLUSTERED (A, B) WITH (FILLFACTOR = 80, IGNORE_DUP_KEY = ON, DATA_COMPRESSION = PAGE, ALLOW_ROW_LOCKS=ON, ALLOW_PAGE_LOCKS=ON) ) INSERT INTO @T (A) VALUES (1),(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12),(13) SELECT t.object_id, t.name, p.rows, a.type_desc, a.total_pages, a.used_pages, a.data_pages, p.data_compression_desc FROM partitions AS p INNER JOIN system_internals_allocation_units AS a ON p.hobt_id = a.container_id INNER JOIN tables AS t ON t.object_id = p.object_id INNER JOIN columns AS c ON c.object_id = p.object_id WHERE = 'dba.se' Duplicate key was ignored.
It took me “few” minutes, before I realised that it was just because I use “sp_RENAME” instead of “sp_rename” :)Pinal Dave is a technology enthusiast and an independent consultant.

SQL Server 2014 in memory OLTP introduces Memory-Optimized Table Types. Both are stored in tables but table variables can use them from the current database (Source). As Aaron points out in the comments the behavior of temporary tables in these differs ) or when the session ends otherwise.If you are using a saved query to execute the table that has had the name altered make sure to reflect this change within the query script.Hi, quite useful article, but I think you should change example, from “sp_RENAME” to “sp_rename”. Normally you will not encounter any problems, but when I was running this against DB with CS collation I was getting error that procedure not exists. We can verify this by running script:while rename a column i have given [ ](bracket while rename a column) so it resulted with the bracket under that column like ‘[price]’. Now, the table name “Table_First” is renamed as “Table_Last”.“Table_First” will no longer be available in database.
