Introduction to the usage of length function The length function is used to return the number of characters or bytes in a specified string. It can be used to calculate the length of a string for operation and judgment when querying and processing string data. It should be noted that the length function counts the number of characters in the string, not the number of bytes. For multibyte character sets, a character may consist of multiple bytes. Therefore, the length function counts multibyte characters as one character when calculating the string length.
