Insert SQL

I am inserting rows in a table. This table is appearing in all namespace as I did global mapping.

So once I run insert command from a method, it insert the rows. When I run the same insert command from other namespace, it replace the existing data in table.

Insert command is same in all namespace but the data I m inserting is different.

From my recent post, I uploaded a set of values into a global, and I am trying to compare the first field, and then

$GLOBAL("123", "bone issue")=""

$GLOBAL("234","joint issue")=""

Now, I want to compare and see if the DG1:4.1 segment has the code $GLOBAL and then replace the DG14.1 segment with the code and the description

so For Eg: if DG1:4.1 exists in $GLOBAL("123") then replace the segment with the code and description

Can someone guide me on how I can achieve this?

Hey InterSystems Community!

This is probably far-fetched - is there a way to get notified/get a piece of code triggered whenever the state of a global changes?

Now what could I possibly want with that? Quite simple! I would like to forward the content of a global (in this case the "FSLog" global written by the FHIR implementation) while adding timestamps to it - to create some sort of file-based logging for it.

Hi,

I have a class with around 400k lines and 60 columns. Class storage is Cache SQL storage (Mapped from a global).

I want to create multiple indices on certain fields.

I am familiar with two approaches:

1. Create a new map (Index type) on a pointer global.

2. Create a bitmap index

Which approach is more recommended to be used in the case I described? If there are any other approaches, I will be happy to hear.

Thanks :)

Hi there have been various posts around how to clean up globals without parent data but none have gone into how you solve these issues.

Our database is approaching 600gb in size so i am looking into how to reduce this.

We use standard purge tasks.

Our cache stream class has a global size of 2463243 from running global size so it is what i would like to tackle first.

1) is there any way i can find based on my oldest message session for where most of these globals
