哪个 MySQL 查询将在表中的一个特定字段中进行文本搜索和替换?

What MySQL query will do a text search and replace in one particular field in a table?

即搜索 foo 并替换为 bar,这样一个字段值为 hello foo 的记录就变成了 hello bar.

I.e. search for foo and replace with bar so a record with a field with the value hello foo becomes hello bar.

推荐答案

更改 table_namefield 以匹配您的表名和相关字段:

Change table_name and field to match your table name and field in question:

UPDATE table_name SET field = REPLACE(field, 'foo', 'bar') WHERE INSTR(field, 'foo') > 0;

  • REPLACE(字符串函数)
  • INSTR(字符串函数)
    • REPLACE (string functions)
    • INSTR (string functions)
