[Tarantool-discussions] Implicit cast for ASSIGNMENT

[Mergen Imeev]

Hi all,
I would like to discuss the second issue of casts in SQL. I mean
implicit casting for ASSIGNMENT.

For now, I suggest avoiding questions about SCALAR, as the
discussion is already in progress.

So, I suggest removing the current implicit casts. We can
reimplement implicit casts in accordance with ANSI in issue #3836.
But since priority of #3836 is low, this is most likely not going
to happen for some time.

At the moment, I see two ways to remove implicit casts:
1) Disable all implicit casts, except casts for numeric values.
These casts will become UDCF later.
2) Disable all implicit casts. Assignment in Tarantool-SQL will
work the same as in noSQL Tarantool.

What do you think about this?
