使用通配符的搜索功能

Question

我正在研究 seach 函數，其中請求來自帶有通配符的前端，並根據請求輸出所需的結果。

假設我們在 DB 中有一個 Name 列，其中包含一些記錄：

Name
---------
political party Delhi, IN (ruling)
political party Mumbai, IN (ruling)
political party Kerala, IN (not ruling)
political party Goa, IN (ruling)

 Now from JSP page request is coming as *Del*ruling* (or request could come just as *Del*) and outcome should be: political party Delhi, IN (ruling). I spent few days but could not find how to implement this functionality. Any guidance will be highly appreciated.

MySQL 支持通配符。 它們由%字符表示並在LIKE語句中使用。 因此，只需將所有 '*' 替換為 '%' 就可以了！

SELECT *
FROM articles
WHERE body LIKE '%Del%ruling%'
