Wildcards are a very useful tool in MySQL, which can help us query and filter data more conveniently. By using wildcards flexibly, we can quickly find data that meets specific conditions. When using wildcards, you need to pay attention to some precautions and try to reduce the scope of the query to improve query efficiency. At the same time, you can also explore some other functions for fuzzy queries, such as regular expressions. I hope this article will help you understand and use MySQL wildcards.
