Structured Query Language, or SQL (pronounced as the letters S-Q-L or the word sequel) is a language for communicating with databases, so you can quickly and easily retrieve all of the valuable information stored inside a database.
Common requests for information in RB9 are built in, and triggered by entering text and/or clicking buttons in the different windows in RB9. You don’t need to know SQL for most information retrieval in RB9. You can make customized searches of your RB9 database, however, using Query Maker’s SQL wizard.
To ask RB9’s database engine to find something, we construct an SQL statement: a string of SQL keywords and supplementary information (such as table and field names) that the database engine understands.
Database tables usually contain large amounts of data, and you seldom need to retrieve all the rows in a table. Usually, you only want the particular data needed for specific operations or reports. Retrieving just the data you want involves specifying search criteria, also known as a filter condition, in SQL.
