是否可以通过这种方式只更新 1 个“产品”？因为如果我有超过 1,000 种产品，更新会非常慢(更新所有字符串)

更好的方法然后通过 SQL 获取字符串选择解码，更改特定值然后更新完整字符串？

谢谢!

Answer 1

要更新存储在 MySQL 中的部分 JSON 字符串，您确实需要检索、解码为数组/对象、编辑、编码为 JSON，然后存储。这很耗时。

我建议更改您的表架构。不确定它现在是如何设置的，但不是让一个表包含您的所有信息，您可以有一个表只用于 Products，另一个用于 Orders，另一个用于客户等

所以在您的 Products 表中，每个产品一行:

ID   |  NAME    | DESCRIPTION      |   PRICE
00123|  jacket  | gray wool jacket |   $4.99

然后在另一个表中需要引用该产品时，只需使用ID值即可。与编辑产品的 JSON 相比，您可以更轻松地更新产品的表格行。。
