Even if your company is still relatively small, it may already be in the process of outgrowing the database that you started with. As this happens, new applications will interface with a larger and more powerful database. Meanwhile, the original database will still play a (reduced) role in business activities. Eventually, you will need to manage a variety of databases, each with its own features, specialized syntax, and connection protocols.
Managing multiple databases either necessitates that you employ multiple client applications or find one that can accommodate all of the databases that you use. One such tool is Navicat Premium. Not only does it support most of the major Database Management Systems (DBMSes), but it is one of the few tools that can simultaneously connect to all of them at once!
In today's blog, we will examine some of the challenges of managing multiple databases and provide some practical examples of how to overcome them using Navicat Premium.
A short time ago, we explored Some SELECT Queries You Must Know. These included determining the lowest and highest value for a column, as well as grouping results by category. Today's blog presents a couple more queries, along with a tip to make your queries almost write themselves!
Many database management and development tools support multiple connections to homogeneous databases, i.e., where they are all of the same type, ALL MySQL, ALL SQL Server, ALL Oracle, etc. On the other hand, very few support heterogeneous database servers, i.e. MySQL AND SQL Server AND Oracle, etc. Don't believe me? Just google it!
With Master-Slave topologies and modern practices such as Database sharding becoming increasingly ubiquitous, database administrators (DBAs) and developers are working with multiple databases more than ever before. Doing so is made a lot easier by software that can accommodate multiple database connections.
The Some SELECT Queries You Must Know blog presented a couple of the most important queries to know, along with some examples. Continuing with that theme, today's blog focuses on the invaluable BETWEEN operator.
