Question

**Database Join Exercise**

The `BLOOD_ADMIN_INFO` table has one row per blood unit associated with an order. Its primary key columns are `ORDER_ID` and `LINE`.

The `MAR_ADMIN_INFO` table has one row per medication administration. The columns `ORDER_MED_ID` and `MAR_BLOOD_INFO_LN` form the foreign key to the `BLOOD_ADMIN_INFO` table.

**SQL Query Example:**

Use the following query to answer the question below:

```sql
SELECT mar.ORDER_MED_ID,
mar.SCHEDULED_TIME,
mar.TAKEN_TIME,
bld.BLOOD_ADMIN_TYPE AS [Blood Type]
FROM MAR_ADMIN_INFO as mar
INNER JOIN BLOOD_ADMIN_INFO as bld
< your SQL here >
```

**Question:**

What join condition is appropriate in `< your SQL here >`?

**Options:**

A. `mar.ORDER_MED_ID = bld.ORDER_ID`

B. `mar.MAR_BLOOD_INFO_LN = bld.LINE`

C. `mar.ORDER_MED_ID = bld.ORDER_ID AND mar.MAR_BLOOD_INFO_LN = bld.LINE`

D. It is not possible to join these tables.

Select one of the following options to determine the correct join condition for the tables in the query.

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.
