RPAD() Alternative: Applying Right Padding in SQL Server

Posted on by Ian

The SQL rpad() function has been widely implemented across many major RDBMSs, including MySQL, Oracle, PostgreSQL, and MariaDB, to name just a few. But when it comes to SQL Server, we have a problem. SQL Server doesn’t currently provide us with an rpad() function.

But that’s not to say we can’t apply right padding in SQL Server. SQL Server still provides us with enough tools to get the job done. With a bit of work, we can get a similar result to what we might be able to achieve with rpad(). It may not be as elegant as a simple rpad() function, but at least it’s an option.

How CONCAT_WS() Works in DuckDB

Posted on by Ian

In DuckDB, the CONCAT_WS() function provides an efficient way to join strings with a specified separator. CONCAT_WS() stands for “concatenate with separator”, and many RDBMSs have such a function.

CONCAT_WS() is particularly useful when you need to combine multiple fields or values with a consistent delimiter.

Let’s explore its features and practical applications.

An Overview of the CONCAT() Function in DuckDB

Posted on by Ian

String concatenation is a common operation in database queries, and many database management systems (DBMSs) provide at least one or two ways to concatenate strings. DuckDB is no exception.

One option for concatenating strings in DuckDB is with the CONCAT() function. This function provides a robust and NULL-safe way to combine strings.

Unlike the concatenation operator (||), CONCAT() handles NULL values gracefully and provides a cleaner syntax for combining multiple strings.

In this article, we’ll explore everything from basic usage to advanced techniques and best practices.
