针对一些常用的接口，ShardingSphere 提供了语法糖，可以简化操作，目前已提供的插件查询语法糖如下：
- 查询
org.apache.shardingsphere.sharding.spi.ShardingAlgorithm接口实现：SHOW SHARDING ALGORITHM PLUGINS - 查询
org.apache.shardingsphere.infra.algorithm.loadbalancer.spi.LoadBalanceAlgorithm接口实现：SHOW LOAD BALANCE ALGORITHM PLUGINS - 查询
org.apache.shardingsphere.encrypt.spi.EncryptAlgorithm接口实现：SHOW ENCRYPT ALGORITHM PLUGINS - 查询
org.apache.shardingsphere.mask.spi.MaskAlgorithm接口实现：SHOW MASK ALGORITHM PLUGINS - 查询
org.apache.shardingsphere.shadow.spi.ShadowAlgorithm接口实现：SHOW SHADOW ALGORITHM PLUGINS - 查询
org.apache.shardingsphere.infra.algorithm.keygen.spi.KeyGenerateAlgorithm接口实现：SHOW KEY GENERATE ALGORITHM PLUGINS
