Simple BIT_XOR() Examples in DuckDB
In DuckDB, the bit_xor() function returns the bitwise XOR of all bits in a given expression.
Here are some basic examples that demonstrate how the bit_xor() function works in DuckDB.
BOOL_OR() Examples in DuckDB
In DuckDB, the bool_or() aggregate function returns true if any input value is true, otherwise it returns false.
Here are some basic examples that demonstrate how it works.

In DuckDB, the bit_or() function returns the bitwise OR of all bits in a given expression.
Let’s see how the bit_or() function works in DuckDB with some basic examples.
Exploring the BIT_AND() Function in DuckDB
In DuckDB, the bit_and() function returns the bitwise AND of all bits in a given expression.
Let’s take a quick look at the bit_and() function, along with some simple examples.
Understanding the TAN() Function in SQLite
The TAN() function in SQLite calculates the tangent of an angle provided in radians. The tangent is the ratio of sine to cosine (or the ratio of the opposite side to the adjacent side in a right triangle).
Using DuckDB’s FAVG() Function for More Accurate Floating Point Averages
The favg() function in DuckDB calculates averages using a floating point summation method known as Kahan summation (or compensated summation). This method helps reduce the accumulation of rounding errors that can occur when many floating point numbers are involved when using the regular avg() function.
A Quick Look at the AVG() Function in DuckDB
In DuckDB, avg() is an aggregate function that returns the average of all non-NULL values in its argument (usually a column).
In this article we’ll take a quick look at this function, along with some basic examples.
Continue readingUnderstanding Type Affinity in SQLite
SQLite is a lightweight, self-contained database engine renowned for its simplicity and flexibility. One of its unique features is the way it handles data types through type affinity, which determines how SQLite associates values with storage classes.
Unlike many database systems that enforce strict type constraints, SQLite’s type affinity system is more flexible, accommodating a broader range of data.
Continue readingAn Overview of ARG_MIN() in DuckDB
In DuckDB, arg_min() is an aggregate function that finds the row with the minimum value in one column and returns the corresponding value from another column at that row. Rows where either of the first two expressions is NULL are ignored.
In this article we explore DuckDB’s arg_min() function with some simple examples.
