How CONVERT() Works in MariaDB
In MariaDB, CONVERT() is a built in function that converts a value to another data type. It takes a value of one type and returns a value of the specified type.
You provide the value as an argument when you call the function, as well as the type that you’d like it converted to.

How CHARSET() Works in MariaDB

We provide the string when we call the function.

In MariaDB, the BINARY operator casts the string following it to a binary string.
The BINARY operator enables you to do a column comparison byte by byte rather than character by character. This causes the comparison to be case sensitive even if the column isn’t defined as BINARY or BLOB. It also means that leading/trailing spaces become significant.
How BIT_LENGTH() Works in MariaDB
In MariaDB, BIT_LENGTH() is a built in string function that returns the length of the given string argument in bits.
You provide the string as an argument when you call the function.
