SQL

Syndicate content 30 

Hi I am experienced with Ensemble but working in my first DeepSee project, so forgive me if this seems elementary. 

My question is, how do I clear  the data out? Every time I build I am adding more and more data. But I would like to revert my cube to being 0 so I can reload it and start over? Set my row count back to 0?

I am unable to remove/purge through the management portal

-I've tried to kill my cube Do ##class(%DeepSee.Utils).%KillCube("MyCube.Cube")  and then Rebuild it. 

 

Thanks In advance

I have several BPL's that act like SQL Server Integration Services (SSIS) where they are transferring data. When I do this they are all being written under 1 session id, is it possible to make the BPL create multiple session ID's as it is cycling through a Snapshot, so it is easier to read in the trace?

Thanks

hi,

i have two where-clauses:

a)  ... WHERE company=1 and product=7

b)  ... WHERE product=7 and company=1 

with other words the position of the where fields are swapped.

now the question is:

bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???

in my point of view, there is a  parser/optimizer who cares about this, so i don't have to care about.

Hello,

I have a small SQL question.  

Running an example queries in our Samples Namespace: 

1. select top 5 Description,Category from Cinema.Film order by Category - runs fine no issues and returns 2 columns as expected

2. select top 5 * from Cinema.Film order by Category - runs fine no issues and returns 8 columns as expected

3. select top 5 Description,Category,* from Cinema.Film order by ID - runs fine no issues, and returns 10 columns, with my first 2 repeated

4. When I try to combine the first 2 queries:

I'm having trouble accessing the snapshots  EnsLib.SQL.Snapshot in %Library.ListOfObjects that are returned from method ExecuteProcedure in EnsLib.SQL.OutboundAdapter.  The Microsoft SQL stored procedure I am executing returns multiple resultsets.

The issue I am having is that my code works fine when executed in the business operation (commented out in the code below) but when it is executed in the business process it errors.  Any ideas as to why this happens?  The error I get is:

Hello,

When i click on the menu to  run the  Data import wizard  from MP, i receive following CSP error

<UNDEFINED>zOnPageHEAD+229^%cspapp.exp.utilsqleximwizardcontent.1 *schemaname : CSP Error

 

It is happening for all the namespaces. Looks like some permission issue.  Same issue with Data Export wizard. Help to resolve this will be appreciated.

I am using

Cache for Windows (x86-64) 2017.2.2 (Build 865_0_18763U)

Thanks,

Jimmy Christian.

 &sql(SELECT colour INTO :colourList FROM favouritecolours)
 While (SQLCODE = 0) 
{
 for i=1:1:$LENGTH($P(colourList,","))
 {

Hi! I've been fiddling with linked tables to get data from other servers, and I encountered a problem that I'm curious about. Maybe I'm not using these tools as intended or there's more going on, so I'm asking here.

I'm running a query on linked table A, something simple like this:

select name from A where id = 5983658923646

And I get this error:

[SQLCODE: <-400>:<Fatal error occurred>]

  [%msg: <>]

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns. 

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:

Class ICT.Experiments.A Extends %Persistent

Property Name As %String;
Property Collection As list Of ICT.Experiments.B;
Property Collection2 As array Of ICT.Experiments.C;

Class ICT.Experiments.B Extends %Persistent

I have the classes above and I can select columns from the array collection by using two joins as follows:

Referencing this post:

https://community.intersystems.com/post/producing-json-sql

I'm not sure how to actually interact with the result set I get from doing something like this.  I want to return something like:

[{"field1":1, "field2":2}, {"field1":2, "field2":10}]

I'm finding it very difficult to get it in this format, since %Print appends a newline onto the end of the {} object it prints.

Here's the closest I've gotten:

We use a lot of external MS SQL calls to look up numerous things when it comes to HL7. I am running into an issue where the outbound calls are queued but the message is sent onto the next process before it gets a response. How do I get it to wait till the response gets back from the MS SQL call before sending it onto the next process?

 

Below is a screen shot of what I am trying to explain...Select Research Study executes at 8:33 the message is sent to the next process at 8:34, but the response of the MSSQL call doesn't come till 9:31.
