The log2()
function in SQLite calculates the base-2 logarithm of a given number.
This function can be useful for scenarios such as binary calculations, information theory, or situations where the base-2 logarithm is needed.

This function can be useful for scenarios such as binary calculations, information theory, or situations where the base-2 logarithm is needed.
Continue readingThe tanh()
function in SQLite calculates the hyperbolic tangent of a number.
The hyperbolic tangent is the ratio of hyperbolic sine to hyperbolic cosine, producing values between -1 and 1.
Continue readingThe SQLite TRUNC()
function is used to truncate a number to an integer. It returns the integer part of its argument rounding toward zero.
TRUNC()
is similar to CEIL()
and FLOOR()
, except that TRUNC()
always rounds toward zero. CEIL()
on the other hand, always rounds up, and FLOOR()
always rounds down.
The LOG()
function in SQLite calculates the logarithm of a given number to a specified base, with 10 being the default base.
This is helpful for logarithmic transformations or calculations requiring a specific base (e.g., base 10 for common logarithms or base 2 for binary logarithms).
Continue readingIn SQLite, the ceil()
and ceiling()
functions are used to return the smallest integer that is greater than or equal to a given number. They both serve the same purpose, and either function can be used interchangeably.
The RADIANS()
function in SQLite is a mathematical function that converts an angle from degrees to radians. This can be handy when working with trigonometric calculations in your database queries, as some mathematical functions (such as SIN()
, TAN()
) expect angles in radians rather than degrees.
The ASIN()
function in SQLite calculates the arc sine (inverse sine) of a given numeric value. The result is the angle in radians whose sine is the specified number.
The ACOS()
function in SQLite is used to calculate the arc cosine (inverse cosine) of a given numeric value. The result is the angle in radians whose cosine is the specified number.
SQLite’s json_valid()
function allows us to check whether a JSON string is well formed or not.
Prior to SQLite 3.45.0 the json_valid()
function only accepts one argument – the value to check. However, from SQLite 3.45.0 (released on 15 January 2024), we can now provide an optional second argument to define what valid – or “well formed” – means.
If you’re getting a SQLite error that reads ‘Parse error: near “LIMIT”‘, it could be that you’re trying to use the LIMIT
clause when using the VALUES
clause as a stand alone statement.
SQLite doesn’t allow us to apply the LIMIT
clause against the VALUES
statement.
However, there is a work around. Below is an example of how we can apply the LIMIT
clause against the VALUES
statement.
