[3pt] SCALAR and NUMBER values in SQL

[TarantoolBot]

Scalar and number values in SQL

Product: Tarantool
Since: 2.10.0-beta1
Root document: ? https://www.tarantool.io/en/doc/latest/reference/reference_sql/
SME: @ ImeevMA

Details

SCALAR values can now be compared with values of any other scalar type,
but cannot be implicitly cast to any other scalar type. This means that
SCALAR values cannot participate in arithmetic, bitwise operations,
concatenation, or functions that, by definition, do not accept SCALAR
values.

NUMBER values now also cannot be implicitly cast to any other numeric
type, which means that NUMBER values cannot participate in arithmetic
and bitwise operations, or in functions that, by definition, do not
accept NUMBER values.

This is one of many changes from @ImeevMA that affect SQL.
I think they should be done together.
