The data returned by the useQuery function is an instance of QueryResult, which contains the results of the query along with some additional information.

​
Properties

An array of Field objects, each one representing a column in the query result. Each Field object has the following properties:

  • name: The name of the column.
  • type: The type of the column data.

The type property can be one of the following values: string, integer, float, boolean, datetime, null, unknown.

rows
unknown[][]

​
Methods

If you need to export the data into different formats, you can use the following methods:

​
.serialize()

Serializes the query result into a JavaScript object.

{
  "rowCount": 2,
  "fields": [
    { "name": "id", "type": "integer" },
    { "name": "name", "type": "string" }
  ],
  "rows": [
    [1, "Alice"],
    [2, "Bob"]
  ]
}

​
.toJSON()

Serializes the query result into a JSON string.

"{\"rowCount\":2,\"fields\":[{\"name\":\"id\",\"type\":\"integer\"},{\"name\":\"name\",\"type\":\"string\"}],\"rows\":[[1,\"Alice\"],[2,\"Bob\"]]}"

​
.toCSV()

Serializes the query result into a CSV string.

"id,name \n 1,\"Alice\" \n 2,\"Bob\""

​
.toArray()

Serializes the query result into an array of objects, where each object represents a row in the query result.

[
  { "id": 1, "name": "Alice" },
  { "id": 2, "name": "Bob" }
