My straight forward solution using [MySQL]MIN
\nSELECT P.PRODUCT_ID, P.PRODUCT_NAME\n    FROM PRODUCT P\nJOIN SALES S\n    USING (PRODUCT_ID)\nGROUP BY PRODUCT_ID\n    HAVING MIN(S.SALE_DATE) >= \'2019-01-0
```\nSELECT P.PRODUCT_ID, P.PRODUCT_NAME\n    FROM PRODUCT P\nJOIN SALES S\n    USING (PRODUCT_ID)\nGROUP BY PRODUCT_ID\n    HAVING MIN(S.SALE_DATE) >= \'2019-01-01\'  \n    AND \n    MAX(S.SALE_DATE) <= \'2019-03-31\'\n```
