WhereClause.notEqual()

David Fahlander edited this page Jun 13, 2016 · 8 revisions

Since v1.2

Syntax

table.where(indexOrPrimKey).notEqual(key)

Parameters

indexOrPrimKey: String Name of an index or primary key registered in Version.stores()
key Key to compare with. The key MUST be a Number, String, Date or Array instance. Booleans are not accepted as valid keys

Return Value

Collection or WriteableCollection depending on table type

Remarks

Queries the collection for all valid values that does not match given value. Note that you will only find values that are valid indexedDB keys.

Given the following data:

{ id: 1, shoeSize: 9 }
{ id: 2, shoeSize: 10 }
{ id: 3, shoeSize: 11 }
{ id: 4 }
{ id: 5, shoeSize: null }
{ id: 6, shoeSize: "abc" }
{ id: 7, shoeSize: false }
{ id: 8, shoeSize: ["a","b","c"]}

And the following query:

db.people.where('shoeSize').notEqual(10).each(function(x) {
    console.log("Found: " + JSON.stringify(x));
});

We get the following result:

Found: "{id:1,shoeSize:9}"
Found: "{id:3,shoeSize:11}"
Found: "{id:6,shoeSize:\"abc\"}"
Found: "{id:8,shoeSize:[\"a\",\"b\",\"c\"]}"

Note that number 4 was not included in the result beause it hadn't a valid shoeSize key so it's not indexed. A valid key is a key of type string, number, Date or Array<string | number | Date>.
