Description

Inserting into a Columnstore table from a view used to work in 1.2 and below. A customer noticed that in 5.x and above that it no longer functions. See this example:

CREATE DATABASE monty;

USE monty;

CREATE TABLE foo (id INT, fname VARCHAR(20));

INSERT INTO foo VALUES (1,'Greg');

CREATE VIEW view_foo as SELECT * FROM foo;

SELECT * FROM view_foo;

CREATE TABLE bar (id INT, fname VARCHAR(20)) ENGINE=Columnstore;

INSERT INTO bar SELECT * FROM view_foo;

– ERROR: The storage engine for the table doesn't support IDB-1011: Insert on VIEW is currently not supported.

However, if we use the wrapper trick, it does work:

INSERT INTO bar SELECT * FROM (SELECT * FROM view_foo) t;

– OK: 1 row affected

Confirmed with the following script:

DROP TABLE IF EXISTS t1,t2;

DROP VIEW IF EXISTS v1;

CREATE TABLE t1 (id INT, fname VARCHAR(20)) ENGINE=InnoDB;

INSERT INTO t1 VALUES (1,'Greg');

CREATE VIEW v1 as SELECT * FROM t1;

SELECT * FROM v1;

CREATE TABLE t2 (id INT, fname VARCHAR(20)) ENGINE=Columnstore;

INSERT INTO t2 SELECT * FROM (SELECT * FROM v1) t;

SELECT * FROM t2;

+------+-------+

| id   | fname |

+------+-------+

|    1 | Greg  |

+------+-------+

INSERT INTO t2 SELECT * FROM v1;

ERROR 1178 (42000): The storage engine for the table doesn't support IDB-1011: Insert on VIEW is currently not supported.

Not new feature. Technical debt. Huge escalation by one of biggest customers. Needs fixing asap.

UPDATE and DELETE also do not work:

DROP TABLE IF EXISTS t1,t2;

DROP VIEW IF EXISTS v1;

CREATE TABLE t1 (id INT, fname VARCHAR(20)) ENGINE=InnoDB;

INSERT INTO t1 VALUES (1,'Greg');

CREATE VIEW v1 as SELECT * FROM t1;

SELECT * FROM v1;

CREATE TABLE t2 (id INT, fname VARCHAR(20)) ENGINE=Columnstore;

INSERT INTO t2 VALUES (1,'Roman');

UPDATE t2,v1 SET t2.fname=v1.fname WHERE t2.id=v1.id;

ERROR 1178 (42000): The storage engine for the table doesn't support IDB-1011: Update on VIEW is currently not supported.

DELETE t2 FROM t2,v1 WHERE t2.id=v1.id;

ERROR 1178 (42000): The storage engine for the table doesn't support IDB-1011: Delete on VIEW is currently not supported.

build tested: 5.6.1 ( Drone #2295 )

Insert test case worked fine now.

As Barkov mentioned, UPDATE and DELETE do not work. Do we plan on fixing them as part of this ticket, or they are out of scope?
