As costing cements its place in the NHS spotlight, costing practitioners are having to not only extract data from ever growing databases, but also search the data for relationships and variables. SQL is a programming language that is designed for managing and processing data. It is particularly useful in handling data where there are relations between different entities or variables of data. This webinar will provide you with an introduction to SQL databases and a basic understanding of how to query. It will teach you to use some of the main commands, including SELECT, AND, OR, NOT, ORDER BY, IN, BETWEEN, NAME AS, COUNT, along with how to join data from more than one table. The webinar will conclude with some top tips to help you save time when processing data.
