Sort database entries
A sort is a condition used to order the entries returned from a database query.
A database query can be sorted by a property and/or timestamp and in a given direction. For example, a library database can be sorted by the "Name of a book" (i.e. property) and in ascending
(i.e. direction).
Here is an example of a sort on a database property.
Sorting by "Name" property in ascending direction
{
"sorts": [
{
"property": "Name",
"direction": "ascending"
}
]
}
Database queries can also be sorted by two or more properties, which is formally called a nested sort. The sort object listed first in the nested sort list takes precedence.
Here is an example of a nested sort.
JSON
{
"sorts": [
{
"property": "Food group",
"direction": "descending"
},
{
"property": "Name",
"direction": "ascending"
}
]
}
In this example, the database query will first be sorted by "Food group" and the set with the same food group is then sorted by "Name".
