“'SELECT *' 仅对单个输入集有效。”

Question

正在尝试学习沙盒中的查询语法 (https://www.documentdb.com/sql/demo)

SELECT food.id FROM food JOIN t in food.tags WHERE t.name = "oil"

这行得通，但是如果我想获取整个文档怎么办，所以我尝试了

SELECT food.* FROM food JOIN t in food.tags  WHERE t.name = "oil"

和

SELECT * FROM food JOIN t in food.tags  WHERE t.name = "oil"

并得到错误：

{
  "errors": [
    {
      "severity": "Error",
      "location": {
        "start": 7,
        "end": 8
      },
      "code": "SC2040",
      "message": "'SELECT *' is only valid with a single input set."
    }
  ]
}

如何取回整个文档？

Answer 1

你想要的是：

SELECT VALUE food FROM food JOIN t in food.tags WHERE t.name = "oil"

“'SELECT *' 仅对单个输入集有效。”

"'SELECT *' is only valid with a single input set."
