In MySQL, the STDDEV() function returns the population standard deviation of a given expression.
STDDEV() is a synonym for the standard SQL function STDDEV_POP(). There’s also a STD() function which also does the same thing, so we can use either of these functions to get the same result.

In MySQL, the BIT_XOR() function returns the bitwise XOR of all bits in a given expression.
XOR is an exclusive OR, and so a XOR b is mathematically equal to (a AND (NOT b)) OR ((NOT a) and b).
In MySQL, the BIT_OR() function returns the bitwise OR of all bits in a given expression.
In MySQL, the BIT_AND() function returns the bitwise AND of all bits in a given expression.
MySQL provides us with a bunch of functions that can modify JSON values. Here are ten functions that we can use to modify JSON values in MySQL.
In MySQL, we have several options when it comes to extracting data from JSON documents. Below are six methods we can use to do this.
MySQL includes some inbuilt functions that can be used to create JSON values, such as JSON arrays, JSON objects, or a quoted string literal.
Here are seven functions that allow us to create JSON values in MySQL.
Below is a list of the JSON functions and operators available in MySQL.
In MySQL, we have several options when it comes to removing the quotes from a JSON value.
For example, normally if we return a string value from a JSON document, we would get that value along with its quotes. But sometimes we might not want the quotes. Below are three methods we can use to unquote a JSON value in MySQL.
