How To Use SQL Statements In Excel
SQL statements can be used to retrieve information from records that may be held in an Excel spreadsheet or a database.
An advantage of using a SQL statement is that you can identify which records to return by stating which of the columns you want to include and the values you want. A benefit of this approach is that you don’t have to re-type existing data, as you can create a SQL statement to get or pull the data for you.
To create a SQL statement, you will need a spreadsheet or database with records that you wish to use as your source, and a new spreadsheet.
For the purposes of this guide, sample data has been created for you to use. In this scenario, the manager of a car dealership wants to pull records for those months where the forecasted sales exceeded the actual sales so he can drill down and examine the reasons why.
