How to Create a Conditional WHERE Clause in PostgreSQL
Let’s walk through some examples to see the importance of the conditional WHERE clause in PostgreSQL, especially when dealing with data that requires extensive filtering.

Discover efficient methods to partition data in your queries. Explore techniques like GROUP BY, window functions, recursive CTE queries, and the DISTINCT ON clause to optimize performance and scalability
Understanding the PostgreSQL version you’re using is crucial for feature availability and informed decision-making, especially with cloud-managed services. Continue reading to learn how to check your PostgreSQL version.
Discover how the LIKE operator enables pattern matching with wildcards and indexing for specific access patterns, focusing on scenarios where the wildcard is at the beginning or end of the pattern. The examples and demonstrations are performed on YugabyteDB, a PostgreSQL-compatible database with variations in storage implementation.
When indexing JSON documents in PostgreSQL, you can add indexes for the access patterns just like with relational table columns. We will walk through an example of this using the Pokémon GO Pokédex as a dataset, utilizing YugabyteDB, a distributed SQL database compatible with PostgreSQL.
DBAs often need to generate SQL statements using SQL queries and then execute them. PostgreSQL has many features that can help. Let’s walk through an example using YugabyteDB, which is Postgres-compatible and provides the same SQL language and catalog views.
The Orafce extension for PostgreSQL can be used to quickly and easily generate random strings to fill in a text column. Let’s look at an example on how to use Orafce, on either your PostgreSQL database or on a PostgreSQL-compatible database, like YugabyteDB.
There are many ways to handle ID generation in PostgreSQL. In this blog, we’ll demonstrate four ways to do so in Sequelize for PostgreSQL and YugabyteDB.
Let’s see how to capture pg_stat_statements from all the nodes in a persistent table to use for analysis. The data can then be stored in YugabyteDB tables, accessible from any node unless purged. Want to see how it can be done?
Every SQL execution in PostgreSQL and therefore in YugabyteDB YSQL takes time to process. A common way to identify how much is time spent on processing is to use the pg_stat_statements view in the database. However, the time visible in pg_stat_statements might differ from the time a database client registers for the execution. Where does this difference come from? Let’s take a look.
