What's the simplest way to check if database exists in MSSQL using VB.NET?

I'm trying to check if a database exists in the Microsoft SQL Server, what's the simplest way to do that? I just want it to return a true or false value then I would create a database if it doesn't exist. Any help would be appreciated, thanks.

You can try the following query :

select * from sys.databases where [name] = <name of database>

Connect to a system-db (master, msdb, tempdb or model) - because you can be sure that they exist! Then you can select the list of database like this:

select * from sys.databases

or if you want to know if a specific db exists:

select * from sys.databases where name = 'NameOfYourDb'

If you connect without a database name in your connection string (belongs to which provider you are using) you should automatically be connect to your default database (which is "master" by default)

Try below one

Declare @Dbname varchar(100)

SET @Dbname = 'MASTER'

if exists(select * from sys.databases where name = @Dbname)
select 'true'
else 
select 'false'

this is specially for SQL Server
