所有已实现的接口:

DatabaseMetaData, Wrapper

直接已知子类:

DatabaseMetaDataUsingInfoSchema
```
public class DatabaseMetaData
extends Object
implements DatabaseMetaData
```
JDBC Interface to Mysql functions
This class provides information about the database as a whole.

Many of the methods here return lists of information in ResultSets. You can use the normal ResultSet methods such as getString and getInt to retrieve the data from these ResultSets. If a given form of metadata is not available, these methods show throw a SQLException.

Some of these methods take arguments that are String patterns. These methods all have names such as fooPattern. Within a pattern String "%" means match any substring of 0 or more characters and "_" means match any one character.
