Ibuprofen is a medication in the nonsteroidal anti-inflammatory drug class that is used for treating pain, fever, and inflammation. This includes painful menstrual periods, migraines, and rheumatoid arthritis. About 60% of people improve with any given NSAID, and it is recommended that if one does not work then another should be tried. It may also be used to close a patent ductus arteriosus in a premature baby. It can be used by mouth or intravenously. It typically begins working within an hour.
Data can be qualitative or quantitative. 1  Qualitative data is descriptive information (it describes something). 2  Quantitative data, is numerical information (numbers).
The data type for the data column will be Decimal(10,5). If we used an integer column, then we would need to concern ourselves with integer math issues, which is not the focus of this blog. As I stated earlier, SQL Server has a built-in function for calculating the average. The Avg function will ignore rows with . So the average of 1, 2, NULL is 1.5 because the sum of the data is 3 and there are 2 rows that are not NULL. 3/2 = 1.5.
