The SQL LIMIT clause constrains the number of rows returned by a SELECT statement.

In today's blog, we'll explore a few of these, using Navicat for PostgreSQL.

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.

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?
