MySQL查询从字段中提取第一个单词

我想运行一个查询，该查询仅从特定字段返回第一个单词，该字段具有多个由空格分隔的单词，我想我可能需要执行一些正则表达式工作来完成此操作?我知道如何使用PHP中的几种方法来执行此操作，但这最好在数据库端执行.任何想法表示赞赏.谢谢.

I would like to run a query that returns the first word only from a particular field, this field has multiple words separated by spaces, I assume I may need to carry out some regex work to accomplish this? I know how to do this using a few ways in PHP but this would best be carried out on the database side. Any ideas much appreciated. Thanks.
