我的名为Approvals的表包含以下列： ID，审批者，PendingAtLevel
批准者的样本值看起来像这样[["ash","bash","rash"],["cat","bat","rat"],["boss"]] which is basically a 2d array。
Andpuntatatlevel指示我的请求在哪里挂起。如果级别为2的待处理状态，则表示该请求可以由以下"cat","bat" or "rat"中的任何人批准。
以下是我的表格示例数据：
Id PendingAtLevel Approvers
1 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
2 2 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
3 3 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
4 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
5 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
6 2 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
7 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
8 2 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
9 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
10 2 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
11 3 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
12 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
13 1 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
14 2 [["ash","bash","rash"],["cat","bat","rat"],["boss"]]
我正在尝试构建一个api，在其中我可以传递用户名（例如“ boss”）作为输入，它将返回我正在等待“ boss”批准的请求
我想为PostgreSQL查询编写一个sql查询，其中当我提供查询参数boss时，它将返回第3和11条记录。
这是Postgresql9.x.x。我已经尝试了一些基本查询，但无法走得更远。我的专长不是sql。
select Id, PendingAtLevel FROM Approvals WHERE SPLIT_PART(Approvers,'],[',?) LIKE '%boss%'
我希望看到以下结果：
Id PendingAtLevel
3 3
11 3
