Adding Parameter to FilterQuery

In our table, we have a column cities, which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String = "CA"

Our filter should run this query to show all cities of state ca

Method Performance Statistics

Hello All,

There are few tools for SQL optimization available and even query builder has Show Plan to give us an estimation of the resources needed to execute.

For Methods - Is there anything similar ??

I would like to see a similar approach as to the time taken for method to execute.

Is Studio Debugger only option ??

PrimaryKey vs Idkey

Just wondering an Insight in the difference between these two indexes

IdKey / PrimaryKey
=================

Property Identifier As %Integer

Index Index1 on Identifier [Idkey]

Index Index2 on Identifier [PrimaryKey]

What's the difference?

1. If I don't have Index1 and only have Index2, then cache does still make its own id.
So how and why do I ever use the PrimaryKey. In Joins ??

Parent/Child Vs One/Many

Just curious to know about the pros and cons of Parent/Child Vs One/Many.

We do use a bit of both.
One big reason we use Parent child is we feel if we delete one global, it gets rid of all child data too and all parent child data is stored in one global. Much easier to manage.

DeepSee passing Filters in Dashboard URL

-- We have our Pivot ready for some data for all accounts. And we want to now filter it by Account

[Account].[H1].Account.&[1]

It works fine at the pivot level and it filters the records. We save the pivot with no filter values as we want users to decide the Account they want to filter for

-Now If i save this pivot without a value of a filter , then obviously it has all records and I want to filter it at the Dashboard level on my page.

URL I am passing
