PHP 遍历 JSON 并通过 T-SQL 保存答案

【问题标题】：PHP Iterate through JSON and save via T-SQLPHP 遍历 JSON 并通过 T-SQL 保存
【发布时间】：2021-12-09 03:44:49
【问题描述】：

我有 PHP 代码从我订阅的网站返回以下值，我的问题是如何循环遍历这个数组并回显每一行？除此之外，如果可能的话，我想将每条记录插入到 MS-SQL 数据库中，最好是通过批量插入。

【问题讨论】：

您的 SQL Server 版本是多少？如果是 SQL Server 2016 或更高版本，您可以将整个 JSON 传递给存储过程，以便一次性加载所有内容，即批量插入。

感谢 Yitzhak，我正在使用 SQL 2018。我尝试运行脚本，但出现错误提示“$.t”附近的语法不正确。
我的答案是遵循 minimal reproducible example 模式。只需将它按原样复制到 SSMS，运行，它就会工作。我在答案中添加了一个小提琴。看看吧。
谢谢伊扎克！我可以看到您的解决方案通过您提供的 Fiddle 完美运行，我喜欢它！我认为我的 SQL 版本中缺少某些内容，因此我遇到了与前面提到的相同的错误。对不起，我也打错了我的 SQL 版本，应该是 2017 年。但奇怪的是，我尝试在 Fiddle 中更改 SQL 版本，它仍然可以正常工作。你知道我在这里缺少什么吗？
它有效！我刚刚使用以下命令将数据库的兼容性级别从 100 更改为 140。谢谢伊扎克和斯库利！你真的很棒！ ALTER DATABASE {我的数据库} SET COMPATIBILITY_LEVEL = 140;
@SnakeBytes，很高兴听到建议的解决方案对您有用。请不要忘记将其标记为答案。

感谢 Skully，它成功了！只需弄清楚批量插入以将记录附加到我的表中。
