Delete or update statement without where clauses

Reports usages of DELETE or UPDATE statements without WHERE clauses.

Without WHERE clauses, DELETE drops all the data from the table, and UPDATE overwrites values for all the table rows.

Example (MySQL):

CREATE TABLE t1 (a TEXT, b INT, c BOOLEAN); update t1 set a = 'Smith'; delete from t1;
