Update statistics for all databases all tables in a server. Right off the bat, your script completely ignores schema, so it will fail unless all of your production servers only use dbo explicitly as the namespace for all tables (and nobody has a default schema other than dbo). You're also using a deprecated data type (NTEXT) for seemingly no reason. Also I don't think the WHERE clause against sys.
I don't know how anything but a U could ever be in there). Not sure why you bother ordering by file size; the job isn't going to finish faster if you handle the biggest databases first (also the join could return multiple rows for a database if it has more than one file in data. You could save quite a bit of work if you add some logic to exclude any tables that don't need it.
My partial solution. This code will be slightly harder to maintain, doesn't have the TRY/CATCH wrappers yours does, and doesn't add any additional logic about which tables to actually pursue, but since I get a kick out of making automation tasks out of dynamic SQL (and really enjoy solutions that cause no horizontal or vertical scrollbars on this site), here you go. When you're happy with the output, comment the print and uncomment the exec.
- Example 1 - sys.databases catalog view SELECT * FROM sys.databases To get a better idea of what this catalog view is comprised of take a look at this documentation. The following is the output for the master database. The result set has been transposed.
- THIS TOPIC APPLIES TO: SQL Server (starting with 2008) Azure SQL Database Azure SQL Data Warehouse Parallel Data Warehouse Contains one row for each database in an instance of Microsoft SQL Server. When SQL Server is first installed, sysdatabases contains entries for the.
- Have to wonder if it is really wise to blindly update stats on every table in every database across your entire instance.
- I have a query which I am using to list databases: SELECT * FROM sys.databases But this query does not work in SQL Server 2000. The following query works in both SQL Server.
- File Sizes May 13, 2013 by Steve Hood There are two scripts I like to use to look at the file sizes on.
DECLARE @sql NVARCHAR(MAX) = N'', @stats NVARCHAR(MAX) = N''. SELECT @sql += N'EXEC ' + QUOTENAME(name) + '.

How to update sys.servers in sql server « SQL Server 2005 – How to find Sql server Uptime. You can update sys.servers table using sp. For adding new server name to local instance of the server basically. Exploring your database schema with SQL In the second part of Phil's series of articles on finding stuff (such as objects, scripts, entities, metadata) in SQL Server. If the caller of sys.databases is not the owner of the database and the database is not master or tempdb, the minimum permissions required to see the corresponding row are ALTER ANY DATABASE or VIEW ANY DATABASE server-level permission, or CREATE.
OBJECT. A null argument name denotes a function return. If the function return or argument is a composite type, this view will have one row for each attribute of the composite type. Attributes are recursively expanded if they are composite. The meanings of ARGUMENT. Together, as a row, they represent a node of a flattened tree.
ARGUMENT. For a referenced record field, this is the index of the field within the record. For a referenced collection element, this is 1 because collection elements do not have siblings. SEQUENCETT. Argument sequence starts at 1. Return type and its recursively expanded (preorder tree walk) attributes come first, and each argument with its recursively expanded (preorder tree walk) attributes follow. DATA. Displays the name of the type declared in the package identified in the TYPE.

To prevent these updates from slowing down the system, they are not protected by latches. Hence values in the MONITOR table are not absolutely accurate. They can be used as a reliable indication of activities in the system.
