The view V_PAT_ADT_LOCATION_HX returns one row of information per bed stay. The column ADT_DEPARTMENT_ID is the ID of the bed's department. The column ADT_DEPARTMENT_NAME is that department's name. Two distinct departments can potentially share the same name. Which of the following queries would return exactly one row per department and display the name of the department? A. SELECT ADT_DEPARTMENT_ID, MIN(ADT_DEPARTMENT_NAME) FROM V_PAT_ADT_LOCATION_HX GROUP BY ADT_DEPARTMENT_ID B. SELECT MIN(ADT_DEPARTMENT_ID), ADT_DEPARTMENT_NAME FROM V_PAT_ADT_LOCATION_HX GROUP BY ADT_DEPARTMENT_ID C. SELECT 'ADT_DEPARTMENT_ID', ADT_DEPARTMENT_NAME FROM V_PAT_ADT_LOCATION_HX GROUP BY ADT_DEPARTMENT_ID D. SELECT ADT_DEPARTMENT_ID, 'ADT_DEPARTMENT_NAME' FROM V_PAT_ADT_LOCATION_HX GROUP BY ADT_DEPARTMENT_ID
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
