The SQL Client: Your Connection to the Database Engine However, it’s important to note that these days, almost all database companies offer free versions of their databases, perhaps with some limitations, oriented towards small businesses. Small companies tend to use free database engines like PostgreSQL or MySQL, while medium-sized companies and corporations tend to use more robust database engines like Oracle, DB2, or SQL Server. A database engine consists of several databases, which in turn consists of tables that store data and procedures that manipulate data.Īs an example, consider the following two independent database engines, one for a company named GoGreen that runs in Oracle and another for a sports retail company named BeOlympic that uses PostgreSQL. In SQL, data is organized and grouped in tables. You’ll also need some additional technical information, like the names of the tables where the data you want to work with will be stored. ![]() ![]() To start, you need to identify what database engine you’d like to use. Getting Started with SQL Queries: Choosing a Database Engine So if you learn SQL while working in Oracle, you can easily change gears and work with SQL Server, PostgreSQL, or any other database engine that uses standard SQL or a derivative of it. It’s important to understand that all database engines speak the core SQL language. That means it’s developed by a community of developers, and anyone can use it for free (including you!). For example, Microsoft developed SQL Server, while Oracle developed the Oracle and MySQL engines.Īmong the engines on this list, PostgreSQL is a special case because it is an open-source database engine. Some of these engines are developed by companies for commercial or limited personal use. There are many different database engines on the market, such as Oracle, SQL Server, DB2, MySQL, and PostgreSQL. Installing a database engine is fairly easy, and it’s the first step you should take to be able to run SQL queries on your computer.

When enabled, the Current query will have a slight highlight. The Run query button will default to Run current, however the dropdown will contain a Run all option. ![]() The correct information would be as follows: Enabled (as default) However, setting Enabled (as default) does change the default to Run current and Enabled (but not default) leaves the default as-is. The default run query button will still be Run current, however the dropdown will contain a Run all option. The Current query will have a slight highlight.
