如何在 CosmosDB 中使用 HAVING
How to use HAVING in CosmosDB
我正在尝试使用以下查询来查看数据库中是否有重复项
SELECT c.VariantNo, count(1) AS jongel FROM c where c.brand = 'XXXX' AND c.Consumer = 'XXX_V2' GROUP BY c.VariantNo HAVING jongel > 1
但是我收到接近 HAVING
的语法错误
如果我有多个具有相同 VariantNo 的文档，如何找到？
根据我的经验，HAVING 不受支持。
作为解决方法，您可以使用此 sql:
SELECT d.VariantNo,d.jongel
from (Select COUNT(1) AS jongel,c.VariantNo from c where c.brand ='cx' and c.Consumer = 'gx' group by c.VariantNo) d where d.jongel > 1
下面是我的测试数据：
[
{
"id": "1",
"VariantNo": 2,
"brand": "cx",
"Consumer": "gx"
},
{
"id": "2",
"VariantNo": 3,
"brand": "cx",
"Consumer": "gx"
},
{
"id": "3",
"VariantNo": 2,
"brand": "cx",
"Consumer": "gx"
},
{
"id": "4",
"VariantNo": 3,
"brand": "cx",
"Consumer": "gx"
},
{
"id": "5",
"VariantNo": 6,
"brand": "cx",
"Consumer": "gx"
}<br>
]
这是输出：
[
{
"VariantNo": 2,
"jongel": 2
},
{
"VariantNo": 3,
"jongel": 2
}
]
