Question

我的表doc中有一个jsonb列（gppermission），其中包含数据

[{"Deny": "true", "Allow": "false", "GroupName": "Group 1 "}, 
 {"Deny": "false", "Allow": "true", "GroupName": "Group 2 "}, 
 {"Deny": "false", "Allow": "true", "GroupName": "Group 3 "}, 
 {"Deny": "true", "Allow": "false", "GroupName": "Group 4 "}]

我需要在此数据中搜索

{"Deny": "false", "Allow": "true", "GroupName": "Group 3 "}

我尝试了以下查询。但没有结果：（

select * from doc as dc ,jsonb_array_elements(dc.gppermission) as e(gp) where e.gp = '{"Deny":"false","Allow":"true","GroupName":"Group 3"}'

看到Query for array elements inside JSON type，但它有一个＆＃39;对象＆＃39;参考，我的json数组是不同的

请帮忙......

我得到了一个解决方案，这可能不是解决这个问题的唯一方法。

select * from doc as dc ,jsonb_array_elements(dc.gppermission) as e(gp) where e.gp ->>'Deny'='false' and e.gp ->>'Allow'='true' and e.gp ->>'GroupName'='Group 1'

在PostsonSQL中搜索jsonb列中的json数组，数据为json数组
