Prior to this patch, the auto-increment feature could only be set
in an INTEGER field of PRIMARY KEY if the PRIMARY KEY consisted of
a single field. It was not possible to use this feature if the
PRIMARY KEY consists of more than one field. This patch allows to
set AUTOINCREMENT for any INTEGER field of PRIMARY KEY. This was
achieved by changing the way the feature is defined. It was
previously defined after the PRIMARY KEY keywords, but now it must
follow the definition of the field to which it belongs.
Example of old definition:
CREATE TABLE t (i INT, a INT, PRIMARY KEY (a AUTOINCREMENT));
Example of new definition:
CREATE TABLE t (i INT, a INT AUTOINCREMENT, PRIMARY KEY (a));
Closes #4217
@TarantoolBot document
Title: The auto-increment feature
The auto-increment feature allows to replace a NULL inserted in an
INTEGER field of PRIMARY KEY with a number generated by sequence
if the field has the feature. This feature can belong to any
INTEGER field of PRIMARY KEY, but no more than one of the INTEGER
fields of PRIMARY KEY can have it.
Definition of the feature should follow the field it belongs to.
Examples of definition of auto-increment feature:
CREATE TABLE t (i INT PRIMARY KEY AUTOINCREMENT);
CREATE TABLE t (i INT AUTOINCREMENT, a INT, PRIMARY KEY(i));
CREATE TABLE t (i INT, a INT AUTOINCREMENT, PRIMARY KEY (i, a));

That’s obvious and I guess already documented.
Instead, I’d rather focus on changes provided by
exactly your patch. What is more, this patch introduces
non-compatible grammar changes, which without doubts
must be documented.
Regarding to patch itself, why did you decide to break current
way of declaration of autoincrement feature? If there was any
discussion, please past it here (I failed to find one in server
dev mailing list).

Why don’t simply use has_autoinc + autoinc_field?
It wouldn’t affect performance, but IMHO code would
look a bit better.

Adding autoincrement to a list of constraint declarations leads to
such unclear error message:
tarantool> CREATE TABLE tt(x INTEGER PRIMARY KEY AUTOINCREMENT AUTOINCREMENT);
---
- error: 'Syntax error in CREATE TABLE: statement cannot have more than one AUTOINCREMENT'
…
Previous version looked better IMHO:
- Syntax error near 'AUTOINCREMENT'

Statement can’t have autoinrement specifier by definition -
it’s table’s property. Thus, more accurate error message
would be:
“Table can’t feature more than one AUTOINCREMENT specifier/field” OR
“Table must feature at most one AUTOINCREMENT specifier/field”
Also, check error messages produced by other vendors.

Test below doesn’t really belong to the issue..

unchanged.

New patch:
From f71cec86f8a19c60c2c71f78d25c473e7495b2e3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] sql: AUTOINCREMENT for multipart PK
Prior to this patch, the auto-increment feature could only be set
in an INTEGER field of PRIMARY KEY if the PRIMARY KEY consisted of
a single field. It was not possible to use this feature if the
PRIMARY KEY consisted of more than one field. This patch defines
two ways to set AUTOINCREMENT for any INTEGER or UNSIGNED field of
PRIMARY KEY.
Closes #4217
@TarantoolBot document
Title: The auto-increment feature for multipart PK
The auto-increment feature can be set to any INTEGER or UNSIGNED
field of PRIMARY KEY using one of two ways:
1) AUTOINCREMENT in column definition:
CREATE TABLE t (i INT, a INT AUTOINCREMENT, PRIMARY KEY (i, a));
CREATE TABLE t (i INT AUTOINCREMENT, a INT, PRIMARY KEY (i, a));
2) AUTOINCREMENT in PRIMARY KEY definition:
CREATE TABLE t (i INT, a INT, PRIMARY KEY (i, a AUTOINCREMENT));
CREATE TABLE t (i INT, a INT, PRIMARY KEY (i AUTOINCREMENT, a));
