【问题描述】*：DM7的MPP环境中，创建了分布表```CREATE TABLE PRODUCTION.PRODUCT_INVENTORY
(PRODUCTID INT NOT NULL REFERENCES PRODUCTION.PRODUCT(PRODUCTID),
LOCATIONID INT NOT NULL REFERENCES PRODUCTION.LOCATION(LOCATIONID),
QUANTITY INT NOT NULL)
DISTRIBUTED BY RANGE (QUANTITY)
(
VALUES EQU OR LESS THAN (100) ON EP01,
VALUES EQU OR LESS THAN (MAXVALUE) ON EP02
);
在DM8中有系统表ALL_TABLES_DIS_INFO可以查询到相关分布字段信息，但DM7中此信息是在哪个系统表可以查到的？
