当然有可能，因为 SQL 轻轻提供 DDL 语句，例如，参见***的数据定义语言 [ ^ ]。

参见此处 [ ^

是。一些示例：

创建SQL Server数据库使用C＃ [ ^ ]

SMO - 管理你的SQL Server！ [ ^ ]

Please help.

I want to create a ms access database through query.

Is it possible?

Database Name=emplyee

e.g. Create database employee

And I want to use that query in coding of C# Windows application to create a new database, programmatically, on a button click.

Of course it is possible, since SQL gently provides DDL statements, see, for instance "Data definition language" at Wikipedia[^].

See here[^]

Yes. Some samples:
