TITLE: ALTER TABLE - ADD column
DESCRIPTION:
FBTEST: functional.table.alter.01
NOTES:
[06.10.2023] pzotov
1. Removed SHOW command for check result because its output often changes.
It is enough for this test to obtain similar data from RDB tables.
Created view and stored function to obtain type name by rdb$fields.rdb$field_type and .rdb$field_sub_type.
2. Made example more complex: add column with charset differ than default one for DB (collate not specified, i.e. it must be default for charset).
