Nickolay Ponomarev c69a1881c7 Change ALTER TABLE constraints parsing ... - merge PrimaryKey and UniqueKey variants - support `CHECK` constraints, removing the separate `Key` struct - make `CONSTRAINT constraint_name` optional - remove `KEY` without qualifiers (wasn't parsed and there doesn't appear to be such a thing) - change `UNIQUE KEY` -> `UNIQUE` - change `REMOVE CONSTRAINT` -> `DROP CONSTRAINT` and note its parsing is not implemented Spec: - ANSI SQL: see <table constraint definition> in https://jakewheat.github.io/sql-overview/sql-2011-foundation-grammar.html#_11_6_table_constraint_definition - Postgres: look for "and table_constraint is:" in https://www.postgresql.org/docs/11/sql-altertable.html		2019-06-02 13:54:11 +03:00
