This method can be satisfied, the expression is transferred to a portion of the group. In this case, we can only use the judgment array.Then according to the resulting array, go to each one to determine the length of each; The code is as follows:Let Strarr = Utils.toarray (val);Let str = ", strlen = 0, num =

(collate) is not the same, so you need to specify the rules of comparison, utf8mb4_unicode_ci is utf8mb4 the character set corresponding to the comparison rules. For example, if the character set is a utf8mb4 database, execute the SQL statement: select * from boy where name=‘xueweihan‘ you need to filter the records in the database with the specified collate rules.Use PostureTo create a database:CREATE DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;To connect to a database
