Delete

The DELETE statement deletes documents that satisfy the predicates in the WHERE clause. If you don't specify the WHERE clause, all documents are deleted.

Syntax

Rule singleDeleteStatement:

Example

SQL query:

DELETE FROM accounts
WHERE age > 30

Explain:

{
  "size" : 1000,
  "query" : {
    "bool" : {
      "must" : [
        {
          "range" : {
            "age" : {
              "from" : 30,
              "to" : null,
              "include_lower" : false,
              "include_upper" : true,
              "boost" : 1.0
            }
          }
        }
      ],
      "adjust_pure_negative" : true,
      "boost" : 1.0
    }
  },
  "_source" : false
}

Result set:

{
  "schema" : [
    {
      "name" : "deleted_rows",
      "type" : "long"
    }
  ],
  "total" : 1,
  "datarows" : [
    [
      3
    ]
  ],
  "size" : 1,
  "status" : 200
}

The datarows field shows the number of documents deleted.
