query( )

Creates a query for retrieving items from a database collection.

The query() function builds a query on the specified collection and returns a WixDataQuery object.

The returned object contains the query definition which is typically used to run the query using the find() function.

You can refine the query by chaining WixDataQuery functions onto the query. WixDataQuery functions enable you to sort, filter, and control the results a query returns.

The query() runs with the following WixDataQuery defaults that you can override:

The functions that are chained to query() are applied in the order they are called. For example, if you sort on an age property in ascending order and then on a name property in descending order, the results are sorted first by the age of the items and then, if there are multiple results with the same age, the items are sorted by name in descending order, per age value.

If the collection that you are querying has references to other collections, by default, the data from referenced collections will not be retrieved. To get the data from the referenced items, you must either use the include() chained function before find() or use the queryReferenced() function instead of query().

Items marked as hidden in the collection are not returned.

When working with Wix app collections, fields in the collections have the following permissions:

  • Can connect to data
  • Can use in dynamic page URL
  • Can be sorted
  • Can be filtered
  • Read-only Check which fields can be used in a query.

When using the query() or get() functions or another data retrieval method following a change to your database collection, the data retrieved may not contain your most recent changes. See Wix-data and Eventual Consistency for more information. To solve this problem, you can use the setTimeout() function to delay retrieving data following any changes to your database collection.
