Class OracleDataBaseQuery

java.lang.Object

org.aoju.bus.shade.screw.dialect.AbstractDatabaseQuery

org.aoju.bus.shade.screw.dialect.oracle.OracleDataBaseQuery

All Implemented Interfaces:

DatabaseQuery

public class OracleDataBaseQuery
extends AbstractDatabaseQuery

Oracle 数据库查询

还是采用从驱动中拿到数据的方式，这里注意一点，一定要加入配置参数remarks为true 否则表和列等说明不会查询出来 hikari： config.addDataSourceProperty("remarks", "true");

不过这种查询性能很慢 https://docs.oracle.com/en/database/oracle/oracle-database/20/jjdbc/performance-extensions.html#GUID-15865071-39F2-430F-9EDA-EB34D0B2D560 所以，只能够通过自定义SQL来了
