This is a preparatory patch-set for adding static and dynamic type
checking to SQL built-in function arguments.
Mergen Imeev (5):
sql: modify arithmetic aggregate functions
sql: introduce SQL built-in functions to parser
sql: separate functions in parser
sql: separate function flags from functions
sql: encapsulate SQL built-in functions opcodes

This patch modifies arithmetic aggredate functions, so after this patch
they will work according to out implicit cast rules. It means that if
argument of SUM ar AVG was INTEGER, then the result will also be
INTEGER. It the argument was DOUBLE, the result will be DOUBLE. NUMBER
values cannot participate in arithmetic operations.
Needed for #4415
Part of #6105

From: Mergen Imeev via Tarantool-patches @ 2021-08-18 14:34 UTC (permalink / raw)
To: vdavydov; +Cc: tarantool-patches
This patch moves SQL built-in functions to parser, so now names of these
functions are new keywords. Also, but to this the number of arguments
for functions with a variable number of arguments will be checked during
parsing. For functions with a constant number of arguments, it is always
checked during parsing.
Part of #6105

From: Mergen Imeev via Tarantool-patches @ 2021-08-18 14:35 UTC (permalink / raw)
To: vdavydov; +Cc: tarantool-patches
This patch separates SQL built-in functions from user-defined functions
when creating a VDBE. This makes it easier to validate user-defined
functions, and we can now modify built-in SQL functions without breaking
user-defined functions.
Part of #6105

From: Mergen Imeev via Tarantool-patches @ 2021-08-18 14:35 UTC (permalink / raw)
To: vdavydov; +Cc: tarantool-patches
This patch separates function flags from function definition. This
allows us not to look for a function where we need its flags, but not
the function itself. It also allows us to search for a function after
the function arguments have been properly initialized, which will help
us to check the types of those arguments.
Part of #6105

Yup, a lot of copy-paste. Hard to distibgush the core of each. This all
could make significantly shorter:

Message-Id: <f06233a02a22ad0d5d97f6c9fdccf58e536182a3.1629505300.git.tsafin@tarantool.org>

Subject: [PATCH] sql: handle sql builtins in parser
To: imeevma@tarantool.org
Refactored a way how builtins declared in parse.y:
- made handling code to not duplicate in each case;
- properly initialized id fallback so they all
could be used in non-functions context.
