Consider the SQL instruction DELETE FROM T WHERE T.KEY = 1, where KEY is the primary key of the table T containing many rows. T belongs to a database which contains other tables and has many constraints on these tables. Select all correct answers. Select one or more alternatives: It is possible due to other constraints, to delete more than one tuples from table T. May update the values of attributes in the database because of referential integrity constraints. May delete no rows because of referential integrity constraints. May delete tables from the database schema, if there are no more rows after deletion. The SQL statement is incorrect May delete more than 1 row from tables in the database because of referential integrity constraints
