mysql - SQL横向视图

Question

如何在 SQL 中使用横向视图从 JSON 字符串中提取值？

表“人”中的示例数据：

name   information
-----  -----------------------
Jen    {"age": 15, "gender":2}
John   {"age": 22, "gender":1}
Jack   {"age": 25, "gender":1}
Pat    {"age": 55, "gender":3}

Answer 1

SELECT name , info\
FROM people\
LATERAL VIEW explode(information) exploded_information_view AS info

应该是这样的：

name / info

Jen    /   "age": 15 \
Jen     /  "gender":2
