> DELETE's using a subquery deletes *all* the rows in the table igonoring any
> condition set by the where clause, here's an example -
> CREATE TABLE IF NOT EXISTS CUSTOMER (
> CUSTOMER_ID INTEGER NOT NULL,
> CUSTOMER_NAME VARCHAR NOT NULL,
> CUSTOMER_CITY VARCHAR
> CONSTRAINT pk PRIMARY KEY (CUSTOMER_ID,CUSTOMER_NAME)
> );
> CREATE TABLE IF NOT EXISTS SALES (
> SALE_ID INTEGER NOT NULL,
> CUSTOMER_NAME VARCHAR NOT NULL,
> SALE_AMOUNT INTEGER
> CONSTRAINT pk PRIMARY KEY (SALE_ID,CUSTOMER_NAME)
> );
> UPSERT INTO CUSTOMER VALUES(1,'MSFT','SEATTLE');
> UPSERT INTO CUSTOMER VALUES(2,'AMZN','SEATTLE');
> UPSERT INTO CUSTOMER VALUES(3,'APPL','CUPERTINO');
> UPSERT INTO CUSTOMER VALUES(4,'TSLA','PALO ALTO');
> UPSERT INTO SALES VALUES(1,'MSFT',1000);
> UPSERT INTO SALES VALUES(2,'AMZN',1000);
> UPSERT INTO SALES VALUES(3,'APPL',1000);
> UPSERT INTO SALES VALUES(4,'TSLA',1000);
> DELETE FROM SALES WHERE CUSTOMER_NAME IN (SELECT CUSTOMER_NAME FROM CUSTOMER
> WHERE CUSTOMER_CITY = 'SEATTLE' ) => Deletes all the rows
> EXPLAIN DELETE FROM SALES WHERE CUSTOMER_NAME IN (SELECT CUSTOMER_NAME FROM
> CUSTOMER WHERE CUSTOMER_CITY = 'SEATTLE' )
