Volatile table with IDENTITY column can’t be inserted with column list

[Weishiun Tsai]

When a table is defined with an IDENTITY column, a row can be inserted with a tuple list using DEFAULT as the IDNTITY column value, or with a column list leaving out the IDENTITY column. With a volatile table, the latter method fails now with error 4193 and 2006.

As shown in the following example, a volatile table t was defined with 3 columns c1, c2, c3. C1 was declared as an IDENTITY column. The first 2 inserts used DEFAULT in the tuple list and they worked fine. The following 2 inserts used a column list specifying c2 and c3. They both failed with error 4193 and 2006.

This is seen on the v1.1.0rc2 (v0422) build.

--------------------------------------------------------------

Here is the entire script to reproduce it:

create schema mytest;
set schema mytest;

create volatile table t (
c1 largeint GENERATED ALWAYS AS IDENTITY,
c2 int,
c3 smallint);

insert into t values (DEFAULT,1,1);
insert into t values (DEFAULT,2,2);
insert into t (c2, c3) values (3,3);
insert into t (c2, c3) values (4,4);
select * from t;

drop schema mytest cascade;

--------------------------------------------------------------

Here is the execution output:

>>create schema mytest;

--- SQL operation complete.
>>set schema mytest;

--- SQL operation complete.
>>
>>create volatile table t (
+>c1 largeint GENERATED ALWAYS AS IDENTITY,
+>c2 int,
+>c3 smallint);

--- SQL operation complete.
>>
>>insert into t values (DEFAULT,1,1);

--- 1 row(s) inserted.
>>insert into t values (DEFAULT,2,2);

--- 1 row(s) inserted.
>>insert into t (c2, c3) values (3,3);

Verified on the v0519 build installed on a cluster. This problem is now fixed:

>>set schema mytest;

--- SQL operation complete.

+>c1 largeint GENERATED ALWAYS AS IDENTITY,
+>c2 int,
+>c3 smallint);
