【问题描述】：

我正在查找从哪个 json 类型的列的表中更新数据的查询。

我的桌子是这样的：

ID |    Details

-------------------------------------------------------------------------------------------

1  | {"_translated": {"en_US": {"is_reviewed": "false"}, "default_locale": "en"}}

2  | {"_translated": {"en_US": {"is_reviewed": "false"}, "default_locale": "en"}}

3  | {"_translated": {"en_CA": {"is_reviewed": "true"}, "default_locale": "en"}}

4  | {"_translated": {"en_CA": {"is_reviewed": "false"}, "default_locale": "en"}}

我想将那些 is_reviewed = false 的行更新为 true。

输出：-

ID |    Details

-------------------------------------------------------------------------------------------

1  | {"_translated": {"en_US": {"is_reviewed": "true"}, "default_locale": "en"}}

2  | {"_translated": {"en_US": {"is_reviewed": "true"}, "default_locale": "en"}}

3  | {"_translated": {"en_CA": {"is_reviewed": "true"}, "default_locale": "en"}}

4  | {"_translated": {"en_CA": {"is_reviewed": "true"}, "default_locale": "en"}}

请有人帮我查询一下。

【解决方案1】：

使用jsonb_set（Postgres 9.5+）

UPDATE t SET details =
jsonb_set(details::jsonb, '{_translated,en_US,is_reviewed}','"true"') where id = 1;
UPDATE t SET details =
jsonb_set(details::jsonb, '{_translated,en_US,is_reviewed}','"true"') where id = 2;
UPDATE t SET details =
jsonb_set(details::jsonb, '{_translated,en_CA,is_reviewed}','"true"') where id = 4;
