Can I use select statements when inserting into a table? - mysql

Question

I have the following table:
DROP TABLE IF EXISTS `worklist`;
/*!40101 SET #saved_cs_client = ##character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `worklist` (
`ID` bigint(20) NOT NULL AUTO_INCREMENT,
`ENTITY_TYPE_CODE` bigint(20) NOT NULL,
`TYPE_CODE` bigint(20) NOT NUll,
`NAME` varchar(255) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=125 DEFAULT CHARSET=utf8;
/*!40101 SET character_set_client = #saved_cs_client */;
Insert INTO code (DISPLAY, CODE_GROUP, CODE_KEY, ALIAS) VALUES ('Duplicate Claims Worklist', 'WORKLIST_TYPE', 'DUPLICATE_CLAIM_WORKLIST', 'Duplicate Claims Worklist');
INSERT INTO code (DISPLAY, CODE_GROUP, CODE_KEY, ALIAS) VALUES ('Claim', 'ENTITY', 'CLAIM', 'Claim');
INSERT INTO worklist (ENTITY_TYPE_CODE, TYPE_CODE) VALUES (SELECT ID FROM code WHERE CODE_GROUP = 'ENTITY' and CODE_KEY = 'CLAIM', SELECT ID from code where CODE_GROUP = 'WORKLIST_TYPE' and CODE_KEY = 'DUPLICATE_CLAIM_WORKLIST');
ALTER TABLE workitems ADD WORKITEMS_ID bigint(20) DEFAULT NULL;

Yes you can you need to omit the Values keyword and do something like this
INSERT INTO code (DISPLAY, CODE_GROUP, CODE_KEY, ALIAS)
SELECT DISPLAY, CODE_GROUP, CODE_KEY, ALIAS
FROM SomeTable
Obviously you will need to include a where clause to control the select statement but that's basically it.
EDIT:
It would look something like this (code is untested and has been typed directly into the editor so may have some speeling mistooks.)
DROP TABLE IF EXISTS `worklist`;
/*!40101 SET #saved_cs_client = ##character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `worklist` (
`ID` bigint(20) NOT NULL AUTO_INCREMENT,
`ENTITY_TYPE_CODE` bigint(20) NOT NULL,
`TYPE_CODE` bigint(20) NOT NUll,
`NAME` varchar(255) DEFAULT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=125 DEFAULT CHARSET=utf8;
/*!40101 SET character_set_client = #saved_cs_client */;
Insert INTO code (DISPLAY, CODE_GROUP, CODE_KEY, ALIAS) VALUES ('Duplicate Claims Worklist', 'WORKLIST_TYPE', 'DUPLICATE_CLAIM_WORKLIST', 'Duplicate Claims Worklist');
INSERT INTO code (DISPLAY, CODE_GROUP, CODE_KEY, ALIAS) VALUES ('Claim', 'ENTITY', 'CLAIM', 'Claim');
INSERT INTO worklist (ENTITY_TYPE_CODE, TYPE_CODE) SELECT A.ID, B.ID FROM (SELECT ID, 1 AS J FROM code WHERE CODE_GROUP = 'ENTITY' and CODE_KEY = 'CLAIM') A LEFT JOIN ( SELECT ID, 1 AS J FROM code WHERE CODE_GROUP = 'WORKLIST_TYPE' and CODE_KEY = 'DUPLICATE_CLAIM_WORKLIST') B ON A.J = B.J;
ALTER TABLE workitems ADD WORKITEMS_ID bigint(20) DEFAULT NULL;
