One row in the PAT_ENC table represents one patient encounter. One row in the ORDER_MED table represents one medication order. One patient encounter can have many medication orders but one medication order can only have one patient encounter. In other words, the cardinality of this PAT_ENC to ORDER_MED relationship is one-to- many. You start a query with ORDER_MED. You then add PAT_ENC using an inner join. What is true about the granularity of the result set before and after adding the PAT_ENC table? A. The granularity stays at one row per patient encounter B. The granularity stays at one row per medication order C. The granularity changes from one row per medication order to one row per patient encounter D. The granularity changes from one row per patient encounter to one row per medication order on an encounter

Task 2: The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields. The CAR_ID and MAINTENANCE_TYPE_ID should be foreign keys to their original tables. Cascade update and cascade delete the foreign keys. SQL DataBase Test: Create a new table to store maintenance operations Test Query: DESCRIBE MAINTENANCES Expected Results Field Type Null Key Default Extra CAR_ID char(5) NO PRI NULL MAINTENANCE_TYPE_ID char(5) NO PRI NULL MAINTENANCE_DUE date NO PRI NULL
Write the following as MySQL query: Find the employee ID, first and last name, and salary for each employee whose salary ismore than $20,000 or who works in the shipping department. Use the UNION set operator. List the country ID, country name, city, and state/province. Be sure all country names areincluded in the result, regardless of whether there is no matching city and state/province. You have to use an outer join.
JOIN TABLES One row in the PAT_ENC table represents one patient encounter. One row in the ORDER MED table represents one medication order. One patient encounter can have many medication orders but one medication order can only have one patient encounter. In other words, the cardinality of this PAT_ENC to ORDER_MED relationship is one-to- many. You start a query with PAT_ENC. You then add ORDER_MED using an inner join. What is true about the granularity of the result set before and after adding the ORDER_MED table? SELECT ONE OF THE FOLLOWING A. The granularity stays at one row per patient encounter. B. The granularity stays at one row per medication order. C. The granularity changes from one row per patient encounter to one row per medication order on an encounter. D. The granularity changes from one row per medication order to one row per patient encounter.
Update table product to set the value of column productType equal to the corresponding id value in the table productType. This requires a SELECT * FROM productType: to see what the id value is for each type. For example, in my database a. 1|meat b. 2| seafood c. 3| vegetable d. 4 grain and rice e. 5 bakery
true/false INNER JOIN combines two relations. It takes the second relation, and appends it to the end of the first relation. In Corelated Subqueries, subquery is executed independent of the outer query: subquery is executed only once. SELECT * FROM sys.Relations displays information about all the user-defined relations within a database. Given GENDER and STUDENT relations, SELECT Gender, FName, LName FROM GENDER LEFT OUTER JOIN STUDENT ON STUDENT.GenderCode = GENDER.GenderCode ≡ SELECT Gender,FName, LName FROM STUDENT RIGHT OUTER JOIN GENDER ON STUDENT.GenderCode = GENDER.GenderCode The statements select RIGHT('I wish I had attended the practice hours', 9) and select…

The OR_CASE table has one bro per surgical case. The OR_LOG table has one row per surgical log. It's LOG_ID column identifies each log. If a case has an associated log, OR_CASE.LOG_ID will store the logs ID. Otherwise, it will be null. A query uses the following join: FROM OR_CASE INNER JOIN OR_LOG ON OR_CASE.LOG_ID=OR_LOG.LOG_ID which of the following would be the results? A. A log with no associated case.B. A log with an associated case. C. A case with no associated log.D. Rows with no case or log.
