I had to use a NOEXPAND hint to get it to use the view. Since the hash is persisted to disk in the indexed view, that's not necessary:įROM dbo.PersonWithHashForSomeReason WITH (NOEXPAND) Notice the lack of a Compute Scalar operator, which would normally be used to produce the hash value. Looking for a specific set of rows in the table produces an index scan (execution plan link). ON dbo.PersonWithHashForSomeReason (BusinessEntityID) I can make that an indexed view by clustering it on BusinessEntityID:ĬREATE UNIQUE CLUSTERED INDEX CX_BusinessEntityID Note: I was too lazy to write my own CLR function, so this one is from this Q&A. In the AdventureWorks2014 sample database, I created this view on the delightfully named Person.Person table:ĬREATE OR ALTER VIEW dbo.PersonWithHashForSomeReasonĭbo.SpookyHash(CONVERT(binary(50), FirstName)) AS FirstNameHash So you can at least avoid the cost of calculating the value on the fly when reading from the table. However, you can include it in the SELECT list of the view definition, which will persist the value to disk. You're right that you can't include the SQLCLR in the index keys of the indexed view. It actually is kind of miserable when you think of an indexed view as a solution, only to find your use case hits on one of the many limitations of indexed views (I'm looking at you, LEFT JOIN). How should I correct the script so that it is run smoothly? Check if instance name is correct and if SQL Server isĬonfigured to allow remote connections. While establishing a connection to SQL Server. SQL Server : A network-related or instance-specific error has occurred Sqlcmd: Error: Microsoft ODBC Driver 11 for Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server Network Interfaces: Error Locating Server/Instance Specified Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : SQL Server Within the Log you can see the following: The script must be executed locally on the server (Windows Server 2012). \SQLEXPRESS -U ENT_LEG_USA -P Ent元gpr0d -Q "EXEC sp_BackupDatabases ='C:\SQLBackups\', -o C:\SQLBackups\LogBK.txt \SQLEXPRESS -Q "EXEC sp_BackupDatabases ='C:\SQLBackups\', -o C:\SQLBackups\LogBK.txt bat file that has the following code: sqlcmd -U USUARIO -P P -S.
