When working with databases, we often encounter rows that lack data. This missing data may result from unknown or inapplicable values, errors during data import or input, or specific calculations involving non-existent values. In such cases, there are two ways to represent missing data: NULLs and empty (or blank) values. While these might seem identical at first glance, they are different and impact essential database operations in distinct ways.

When working with MySQL databases, you may encounter the need to change a database name. However, MySQL no longer supports a direct renaming option. The RENAME DATABASE command, available in earlier versions, was removed due to the risk of data loss. Despite this, renaming a database in MySQL is still possible.

Ad-hoc queries are temporary SQL queries created and executed to perform a specific task without prior preparation or to save as permanent procedures or functions. Usually, they can be used to analyze data, search for particular information, or solve temporary tasks. However, if user-defined input data generates the text in ad-hoc queries dynamically, they may be vulnerable to SQL injections. In the article, we’ll explore what ad-hoc queries are and what security and access risks they may cause.

Imagine you’re working in a UNIX-based environment, managing multiple databases like MariaDB, PostgreSQL, or Oracle, and you have to connect their data to different applications. Without UNIX ODBC drivers, you’d have to write custom code for each database, which would quickly turn into a nightmare — each database has its own way of handling queries, connections, and authentication. Luckily, ODBC drivers can save the day by acting as “translators”.
