I need to "compute when compose" a field in a document so Client+Formula are the only options I have here.
I am using a #DbLookup("" :"NoCache";"server" :"db" ;"View" ; "key" ; fieldName); command that looks into a different server/database and comes back with a UNID of a specific document. The UNID is valid for the server/db database, not the current one. How can I use this UNID to fetch/set a value on the remote document.
In IBM documentation I only found #GetDocField(UNID,fieldName) and #SetDocField(UNID, fieldName, value) that are for the local DB only!!!
How can one actually meaningfully use this UNID since it represents a document on a remote database. I searched for 40 minutes for an answer!
This is not possible using formula language.
In LotusScript you can use
Dim db as New NotesDatabase( "server" , "db" )
Dim doc as NotesDocument
Set doc = db.getDocumentByUnid( uuid )
Call doc.ReplaceItemValue( "fieldname" , value )
if you really are not able to use lotusscript in the context you have (normally there IS an option to use LotusScript wherever / whenever you need it, you probably only try to use the wrong context / event / whatever), then the possibility would be to write a litte LotusScript- Agent with the above code and hand the uuid to it via notes.ini- Parameter, profile- document or whatever fits best for you.
My reputation is too low to comment, so I have to resort to posting an answer to add a thought. Have you tried #UpdateFormulaContext?
UNID := #DbLookup(...[ReturnDocumentUniqueID]);
#Command([OpenDocument]....UNID);
#UpdateFormulaContext;
#SetDocField(#DocumentUniqueID; ...);
#UpdateFormulaContext definitely allows you to reset the 'current' document (from the IBM Domino Designer Help):
tempDate := #GetDocField(#DocumentUniqueID;"CreatedDate");
#Command([NavPrev]);
#Command([EditDocument]);
#UpdateFormulaContext;
#SetDocField(#DocumentUniqueID;"nextCreated";tempDate)
"You can use #UpdateFormulaContext to extract values from or set values in external documents. You can even access document- and database-specific information using functions such as #DbName, #DbTitle, #Created, #DocumentUniqueID, #GetDocField, #GetField, #GetProfileDocument."
Worth a punt.

My application use keywords extensively, everything is tagged with keywords, so whenever use wants to search data or add data I have to show keywords in auto complete box.
As of now I am storing keywords in another collection as below
export interface IKeyword {
Id:string;
Name:string;
CreatedBy:IUserMin;
CreatedOn:firestore.Timestamp;
}
export interface IUserMin {
UserId:string;
DisplayName:string;
}
export interface IKeywordMin {
Id:string;
Name:string;
}
My main document holds array of Keywords
export interface MainDocument{
Field1:string;
Field2:string;
........
other fields
........
Keywords:IKeywordMin[];
}
But problem is auto complete reads data frequently and my document reads quota increases very fast.
Is there a way to implement this without increasing reads for keyword ? Because keyword is not the real data we need to get.
Below is my query to get main documents
query = query.where("Keywords", "array-contains-any", keywords)
I use below query to get keywords in auto complete text box
query = query.orderBy("Name").startAt(searchTerm).endAt(searchTerm+ '\uf8ff').limit(20)
this query run many times when user types auto complete search which is causing more document reads
Does this answer your question
https://fireship.io/lessons/typeahead-autocomplete-with-firestore/
Though the receommended solution is to use 3rd party tool
https://firebase.google.com/docs/firestore/solutions/search
To reduce documents read:
A solution that come to my mind however I'm not sure if it's suitable for your use case is using Firestore caching feature. By default, firestore client will always try to reach the server to get the new changes on your documents and if it cannot reach the server, it will reach to the cached data on the client device. you can take advantage of this feature by using the cache first and reach the server only when you want. For web application, this feature is disabled by default and you can enable it like in
https://firebase.google.com/docs/firestore/manage-data/enable-offline
to help you understand this feature more check this article:
https://firebase.google.com/docs/firestore/manage-data/enable-offline
I found a solution, thought I would share here
Create a new collection named typeaheads in below format
export interface ITypeAHead {
Prefix:string;
CollectionName:string;
FieldName:string;
MatchingValues:ILookupItem[]
}
export interface ILookupItem {
Key:string;
Value:string;
}
depending on the minimum letters add either 2 or 3 letters to Prefix, and search based on the prefix, collection and field. so most probably you will end up with 2 or 3 document reads for on search.
Hope this helps someone else.
I want to customize the standard drill-down functionality and add a text parameter to the drill-down URL. I will then parse and use the parameter in the SysStartUpCmdDrillDown or EventDrillDownPoller class like the solution provided by Jan B. Kjeldsen in this question.
The standard drill-down link is dynamics://Target/?DrillDown_RecID/ :
dynamics://0/?DrillDown_5637230378/
In previous versions of AX it was possible to modify the RecId to custom text and parse the text once the client is started:
dynamics://0/?DrillDown_0MenuItemName=PurchTable&FieldName=PurchId&FieldValue=P000044
Unfortunately, in AX 2012 the RecId is checked before the client is started and if it is not a valid int64, the drill-down event is not sent to the client. Since it is not possible to change the RecId to anything other than an integer, #Alex Kwitny suggested in the comments at that same question that you can add the custom text to the drill-down target like this:
dynamics://0MenuItemName=PurchTable/?DrillDown_5637230378/
The problem I experience with this is that the link now gets confused about which instance to start.
If the target is equal to the value in the System Admin -> system parameters -> Alerts ->Drill-down target, a client with the correct server instance is started. When I append the text with my custom text, it always starts the default instance(Which could be different from the instance I intended to start). While this is not ideal, I could work around this issue.
The bigger problem is that it now always starts a new session of the default instance, even if a client session is already started. As far as I can see I cannot write X++ code to solve this issue since the server instance is determined before any code in the client is executed.
My question is this - How can I add custom text to the drill-down link while preserving the way the client instance is started: If a client for the instance is already open, it should process the link in the open client, and not start up a new client of the default instance.
You should probably come up with another solution as mentioned in this post, but there could still be a way.
The URL has two objects that can be modified:
dynamics://[Drill-down target(str)]/?Drilldown_[Int64]
According to you, if you modify the [Drill-down target], then it launches AX using the default client config, and that is behavior that you don't want. If you have a matching [Drill-down target], it'll launch in the open client window, which is behavior I can't confirm, but I'll take it at face value and assume you're correct.
So that means the only thing you can modify in the URL is [int64]. This is actually a string that is converted to an int64 via str2int64(...), which in turn corresponds to a RecId. This is where it gets interesting.
This work all happens in \Classes\SysStartUpCmdDrillDown\infoRun.
Well, lucky for you the ranges for the objects are:
RecId - 0 to 9223372036854775807
Int64 - -9223372036854775808 to 9223372036854775807
You can call minRecId() and maxRecId() to confirm this.
So this means you have -9223372036854775808 to -1 numbers to work with by calling URLs in this range:
dynamics://0/?DrillDown_-1
to
dynamics://0/?DrillDown_-9223372036854775808
Then you would modify \Classes\SysStartUpCmdDrillDown\infoRun to look for negative numbers, and fork to your custom code.
HOW you decide to user these negative #'s is up to you. You can have the first n-digits be a table id or a look-up value for a custom table. You can't technically use a RecId as part of that negative number because in theory the RecId could get up that high (minus 1).
I need to fetch from BaaS data store all records that doesn't match condition
I use query string like:
https://api.usergrid.com/<org>/<app>/<collection>?ql=location within 10 of 30.494697,50.463509 and Partnership eq 'Reject'
that works right (i don't url encode string after ql).
But any attempt to put "not" in this query cause "The query cannot be parsed".
Also i try to use <>, !=, NE, and some variation of "not"
How to configure query to fetch all records in the range but Partnership NOT Equal 'Reject' ?
Not operations are supported, but are not performant because it requires a full scan. When coupled with a geolocation call, it could be quite slow. We are working on improving this in the Usergrid core.
Having said that, in general, it is much better to inverse the call if possible. For example, instead of adding the property when the case is true, always write the property to every new entity (even when false), then edit the property when the case is true.
Instead of doing this:
POST
{
'name':'fred'
}
PUT
{
'name':'fred'
'had_cactus_cooler':true
}
Do this:
POST
{
'name':'fred'
'had_cactus_cooler':'no'
}
PUT
{
'name':'fred'
'had_cactus_cooler':'yes'
}
In general, try to put your data in the way you want to get it out. Since you know upfront that you want to query on whether this property exists, simply add it, but with a negative value. The update it when the condition becomes true.
You should be able to use this syntax:
https://api.usergrid.com/<org>/<app>/<collection>?ql=location within 10 of 30.494697,50.463509 and not Partnership eq 'Reject'
Notice that the not operator comes before the expression (as indicated in the docs).
I have not seen any discussion or awareness so far that Firebase does in fact make available a unique identifier--in fact the full URL--to each specific data record via their "snapshot" which they return, i.e. the wrapper around the data record (accessed via snapshot.val()). By doing a basic property examination of the snapshot I discovered that the unique URL is available (see examples below). However, it seems that, for some reason, Firebase keeps changing the name of the key every few days, causing my application to break. I have to go in and re-discover the new URL property key and change it so that it will work again.
Here are three examples of how I have seen the key change so far. Each value is the same, but the key keeps changing over time (i.e.: "Wb", "Xb", "bc").:
getMemberBySnapshot - snapshot has prop Wb with value https://prototype1.firebaseio.com/users/-IwohKfw1l5F3gFqyJJ5
getMemberBySnapshot - snapshot has prop Xb with value https://prototype1.firebaseio.com/users/-IwohKfw1l5F3gFqyJJ5
getMemberBySnapshot - snapshot has prop bc with value https://prototype1.firebaseio.com/users/-IwohKfw1l5F3gFqyJJ5
I have read Firebase's suggestions that developers should use an email address if they want a unique key (what if my model does not use an email field? What if a user wants to change their email?), or Firebase suggests altenatively to retrieve all existing records and then search through them on the client. Neither of these solutions are satisfying. But I'm seeing that they do provide the unique URL to each data record in the 'snapshot'. Why do they not provide a stabilized key so that a developer can call it consistently???
Firebase.js is a compiled script. The names of internal variables will change every time we compile it and release a new version, so you should definitely not be relying on any properties that are not documented on our website.
For your specific case, you should be using:
snapshot.ref().toString()
in order to get the URL.
There is a GetLastInsertId method in WebMatrix. However, using Reflector, I can see that it's implemented like this:
[return: Dynamic]
public object GetLastInsertId()
{
return this.QueryValue("SELECT ##Identity", new object[0]);
}
Which, as far as I can see, is a very bad way of doing it, because ##Identity returns the last insert considering every table and every session. I need this restricted to the scope and session I'm working with, so I was expecting this to use SELECT SCOPE_IDENTITY(), since that also seems to be what is most often used according to my reading.
My questions are:
Do the WebMatrix wrappers do something that makes this ok to use in my case?
If not, is there a simple way to get the inserted ID of an insert query using WebMatrix classes, or should I fall back on stuff like SqlClient for this?
I am interested in answers for SQL Server (not compact) if that makes a difference.
I had the same problem, and I read these answers but still couldn't get the code to work correctly. I possibly was misreading the solutions above, but what seemed to work for me was as follows:
var db=Database.Open(...);
var lastInsertID = db.QueryValue("INSERT name into Names; SELECT SCOPE_IDENTITY()");
To quote David Fowler, one of the devs on the Data APIs in WebMatrix: "[SCOPE_IDENITTY] doesn't work on ce". Since we wanted a data API that would work on both CE and regular SQL Server, we used ##Identity. So if you want to use SCOPE_IDENTITY specifically, you should use db.QueryValue method:
var db = Database.Open(...);
db.Insert(...);
var lastInsertId = db.QueryValue("SELECT SCOPE_IDENTITY()")
here is my solution
var db.Database.open('..');
var lastId = db.GetLastInsertId();
