#SQL

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method"). // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Hello,

I have a global whose structure is multi-level and I am trying through a class and a SQL query to display a table which includes all the values ​​and levels.

The program below works perfectly when I call it directly from the Terminal, however when I call it from within a CSP it does not work (It does not do the SELECT).

In the USER namespace, the program works both in the Terminal and on the CSP , but in another namespace it only works when called directly in the Terminal.

InterSystems FAQ rubric

By specifying the start and end values ​​of the IDs for which you want to rebuild indexes in the arguments of the %BuildIndices() method provided in the persistent class (=table) definition, you can rebuild only the indexes within that range.

I cannot get any further hint from the error message in red in this screenshot. Is there any clue or details about the connection failure that I could look for?

I found the thread that discusses object mapping, in particular mapping a common global among more than one namespace. The example that is given is a simple one when it's ^global(sub1, ^global(sub2, etc. However I'm having trouble getting this to compile/work when the global has a fixed subscript amongst variable ones.

I have this global in namespaces LAB and ARK in the following format:

^CB(1,sub1)=....

^CB(1,sub2)=...

^CB(1,sub3)=...

Here is what I have for this. In it's current state it throws tons of errors:

hi，
I followed the example of the system and wrote a method to connect to an external database to obtain a result set, but I couldn't get the result.
can anyone please help on this.

If I had:
________________________________________
Class MN.Student Extends %Persistent
{
Property Name As %String;
________________________________________
Class MN.Course Extends %Persistent
{
Property TeacherName As %String;
Relationship StudentName As MN.Student [ Cardinality = one, Inverse = Name ];
________________________________________

For "Cardinality = one" the SQL line below would be sufficient for archiving
INSERT INTO MN.Course (TeacherName, StudentName) VALUES ('Pierre','3')"

InterSystems IRIS currently limits classes to 999 properties.

But what to do if you need to store more data per object?

This article would answer this question (with the additional cameo of Community Python Gateway and how you can transfer wide datasets into Python).

The answer is very simple actually - InterSystems IRIS currently limits classes to 999 properties, but not to 999 primitives. The property in InterSystems IRIS can be an object with 999 properties and so on - the limit can be easily disregarded.

Hi All,

I am facing some issues. I am having a SQL query that is executed using %SQL.Statement ExecDirect() method. Now I want to convert it into Embedded SQL using &SQL().
But where clause is dynamic in my case and It may contain 3-4 clauses.

I'm trying to execute SQL on a EC2 via SSM:

import boto3

instanceid = "i-123456789"
sql = """SELECT path FROM Security.Applications WHERE ID = '/csp/sys'"""
template = """su - irisusr -c 'cat << EOF | iris sql iris -U %SYS
                """ + sql + """
                        q
                        EOF'
                       """
template = [line.strip() for line in template.splitlines()] 
template = """\n""".join(template) 
ssm_client = boto3.client('ssm') 
response = ssm_client.send_command(
            InstanceIds=[instanceid],
            DocumentName="AWS-RunShellScript",
            Comment=AWS,
            Parameters={'commands': template})

Hi All,

I am trying to fetch resultset using the below code -

set rs = ##class(%ResultSet).%New("Simple.Person:ValidateAge")

do rs.Execute()

it is giving me error while the same code I run it through iris terminal worked fine.
I want to understand that problem behind this. Also how can I check the possible methods that I can use on 'rs' somewhat dir() does in python.

Is "time" a reserved word in the %CONTAINS function?

When I run the following SQL query, I get 0 matching results

SELECT ID, text
FROM Test.Sentence
WHERE text %CONTAINS('time') OR text %CONTAINS('time ') OR text %CONTAINS(' time')

However, when I run a query where the search string contains words other than "time" alone, it returns the expected matching results
