Let's say we have a container with following items
{
location:CA,
bool: false
}
{
location:CA,
bool: false
}
{
location:CA,
bool: false
}
How do we write a stored procedure to query all items and update all item's bool field from false to true? I have not find any reference yet and I know CosmosDB stored procedure only support querying not updating or deleting.
This stored procedure code:
// SAMPLE STORED PROCEDURE
function sample() {
var collection = getContext().getCollection();
// Query all documents in one logic partition
var isAccepted = collection.queryDocuments(
collection.getSelfLink(),
'SELECT * FROM root r',
function (err, feed, options) {
if (err) throw err;
if (!feed || !feed.length) {
var response = getContext().getResponse();
response.setBody('no docs found');
}
else {
feed.forEach(element => {
element.bool = true;
collection.replaceDocument(element._self, element,function (err){
if (err) throw err;
})
})
var response = getContext().getResponse();
response.setBody("replace success");
}
});
if (!isAccepted) throw new Error('The query was not accepted by the server.');
}
Execute stored procedure:
BTW, your partition key should be /location.
