I have what I think is a unique situation. I recently deployed an application that uses several databases in SQL Express. One of the databases is named "update". For my SQL Express deployments, I typically script the backups using the following command.
```
BACKUP DATABASE update TO DISK = N'C:\SQLBackups\update.bak' WITH INIT
```
This works great for the rest of the databases but not for the one called update. When I try to run the command I get the error; Incorrect syntax near the keyword update. I have tried putting update in both single and double quotes but I get the same result.
I assume SQL is confused and thinks I am trying to run an update command. Does anyone have any insight or any suggestions on how I can make SQL understand that is a database name? This is a vendor-supplied application so I am unable to change the DB name.

Fortunately, it's as simple as wrapping the database name in brackets -- i.e.,
```
BACKUP DATABASE [update] TO DISK = N'C:\SQLBackups\update.bak' WITH INIT
```
Your vendor is at best, uninformed about polite society's rule against using keywords as object names, and perhaps a bit sadistic. 🙂

Have you tried putting the database name in square [ ] brackets?

Thanks

Thank you for this. Putting it in brackets worked perfectly. I believe they were uninformed. The application is actually developed by the New York State Police and provided free to local police departments. It's very unpolished.

that reminds me of one of those bad practice examples i wrote, to show how confusing keywords as object names could be.

IF NOT EXISTS(SELECT 1 FROM sys.databases WHERE name ='SELECT')
  CREATE DATABASE [SELECT];
GO
USE [SELECT];
GO
CREATE SCHEMA "SELECT";
GO
CREATE TABLE [SELECT].[SELECT]([SELECT] INT IDENTITY(1,1) NOT NULL PRIMARY KEY, 
                      "[SELECT]" VARCHAR(10) DEFAULT 'SELECT');
                      
INSERT INTO [SELECT].[SELECT] DEFAULT VALUES ;

SELECT 
  [SELECT].[SELECT] --TableName.ColumnName
   "SELECT", --Alias
   [SELECT]."[SELECT]" --TableName.ColumnName 
   "SELECT" --Alias
   FROM [SELECT].[SELECT].[SELECT]  ---DatabaseName.SchemaName.TableName
   [SELECT]--Alias 
   WHERE "[SELECT]" --ColumnName 
    = 'SELECT'; --Static String
