Question

I have to create a query which should create a database by concatenating the machine name and any given name. I have following SQL query but I am getting an error. Please suggest me.

DECLARE @machinename VARCHAR(100)    
SET @machinename=HOST_NAME()   

CREATE DATABASE @machinename+' Test'

Answer 1

You need to use Dynamic SQL and you need to remove the space in the ' Test' portion:

DECLARE @machinename VARCHAR(100)    
declare @sql varchar(max)
SET @machinename=HOST_NAME()  
set @sql = 'CREATE DATABASE ' + QUOTENAME(@machinename + '_Test')

execute(@sql)

From MSDN Database identifiers:

Embedded spaces or special characters are not allowed.
