1、首先我们打开数据库并连接，这里我们选择默认连接。

2、然后我们点击新建查询。

3、只之后我们输入以下代码：drop database xj后选中点击执行命令。

4、此时我们可以看到无法删除，因为当前在使用这个数据库。

5、需要切换到其他数据库。

6、然后我们再重复刚才的删除 *** 作。

7、完成图如下。

The NIST 08 mass spectral database, the successor to the NIST 05, is a fully evaluated collection of electron ionization (EI) mass spectra. It also contains MS/MS spectra and GC data. It is the product of a two decade, comprehensive evaluation and expansion of the world's most widely used mass spectral reference library by a team of experienced mass spectrometrists in which each spectrum was examined for correctness.
