查询语句：select * from tb

where info->'$.name' = '特价促销'  or JSON_CONTAINS(info->'$[*].name', '"特价促销"', '$')

查询语句：SELECT * FROM nlu_define_table WHERE

JSON_CONTAINS(JSON_ARRAY("我","想","销","存单"),keywords->'$.keywords') ORDER BY weights DESC;

其他查询语句：

SELECT * FROM nlu_define_table;

SELECT * FROM nlu_define_table WHERE

keywords LIKE "%销%";

SELECT * FROM nlu_define_table WHERE

JSON_EXTRACT(keywords,'$.keywords') LIKE "%销%";

SELECT * FROM nlu_define_table WHERE

keywords -> '$.keywords' LIKE "%销%";

第三条sql和第四条sql是等效。
