And when applied on a string, this function, called len, will tell you the length of a string.So that's going to tell you how many characters are in the string.And characters are going to be letters, digits, special characters, spaces, and so on. ...
CREATE FUNCTION SPLIT_STR( x VARCHAR(255), delim VARCHAR(12), pos INT ) RETURNS VARCHAR(255) RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos), LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1), delim, ''); 定义完成后,通过命令:SELECT SPLIT_STR(string, delimiter, position) 使用...
Return a copy of the string where all characters occurring in the optional argument deletechars are removed, and the remaining characters have been mapped through the given translation table, which must be a string of length 256. You can use the maketrans() helper function in the string module...
Determining String Length The string functionlen()returns the number of characters in a string. This method is useful for when you need to enforce minimum or maximum password lengths, for example, or to truncate larger strings to be within certain limits for use as abbreviations. ...

In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
