This article introduces the knowledge about "sql storage procedure to obtain the method of Chinese phonetic first letter function". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

The copy code is as follows:
