Subject [jira] [Commented] (HIVE-7018) Table and Partition tables have column LINK_TARGET_ID in Mysql scripts but not others
Date Tue, 17 Mar 2015 13:51:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-7018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14365134#comment-14365134
] 

Xuefu Zhang commented on HIVE-7018:
-----------------------------------

Patch looks fine. However, I don't quite understand why we are also removing the following:
{code}
-  CONSTRAINT `PARTITIONS_FK2` FOREIGN KEY (`SD_ID`) REFERENCES `SDS` (`SD_ID`),
...
-  CONSTRAINT `TBLS_FK2` FOREIGN KEY (`DB_ID`) REFERENCES `DBS` (`DB_ID`),
{code}

This doesn't seem related to LINK_TARGET_ID.

> It appears that at least postgres and oracle do not have the LINK_TARGET_ID column while
mysql does.
