#SQL

Hi All -

I was wondering if the below query could be enhanced to automatically look back 24 hours from the current datetime the query is run. As is now I, of course, have to update the date range in the WHERE clause manually.

The query is just getting all MessageBodyClassNames, counting them and then doing an AVG on TimeCreated and TimeProcessed. Nothing too complex.

SELECT MessageBodyClassName, count(ID) as Count_Of_Messages, avg(datediff(ss, TimeCreated, TimeProcessed)) as avg_processing_time_in_seconds

FROM %PARALLEL Ens.MessageHeader

What is the difference between %ID and ID in a database table? Both seem to reference the same column labelled ID.

For context, I am trying to create a viewer class for an existing persistent class.

Let us call the persistent class A, with SqlTableName = OldA.

The viewer class will be B with SqlTableName = A and ViewQuery = {select %ID, <other fields> from <some other class with the same fields as A>}

Say I have a property in a persistent class that stores list of colours and I would like to query that field and return a list and be able to loop that list to get individual colours how will l go about achieving this I have tried something like this but its not working as expected

 &sql(SELECT colour INTO :colourList FROM favouritecolours)
 While (SQLCODE = 0) 
{
 for i=1:1:$LENGTH($P(colourList,","))
 {
 set fvalue=$P(colourList,",",i) 
write "the first"_fvalue,i, 
} 
}

Hi,

I'm getting thousands of errors like the ones below:

2021-05-03 14:11:44 [SQLCODE: <-400>:<Ocorreu um erro fatal>] [Cache Error: <<READ>Dispatch+14^%SYS.BINDSRV>] [Location: <ServerLoop>] [Client info: <Username: KIORAS, Node Name: 3IK0VLS5UU, IP Address: 192.168.1.223, Executable Name: EXTRService.exe, Internal Function: B0>] [%protocol: <52>] $Id: //ce/2018.1.2/kernel/common/src/aclass.c#1 $ 23468 104

Hi ,

When I use jdbc driver to query the column info ,the "REMARKS" field always show the same as the "COLUMN_NAME" field.

When I use the sql "select * from INFORMATION_SCHEMA.columns a where a.table_name='some table name ' " to query columns info,there has a "DESCRIPTION" field ,the value is some comment for the current field.

So is there anyway to return the description to the jdbc remarks field? And is there anyway to update the desciption or remarks field? Or is there some other way that I don't know to manage column comment info?

Hi, I have used CSP to exec SQL selects from any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

DSN CLIENT ONE

CSP Webpage:

TEXTBOX: Introduce your select:

HI I am using below code to retrieve the last inserted ID of the table. It works when we do not set any custom column as IDKey. If we define any column as

IDKey below code does not return any IDKey. I know when i am defining any column as IDKey its not auto generated , but whats the best way to get the ID column value

Greetings all,

I have a quick SQL question. I am working with a class, which has a calculated property, which in turned indexed.
The calculation for this property is created based on another property value via:
SqlComputeOnChange = attributes - so basically every time I add a property attribute to my class, my new property
is calculated based on some SqlComputeCode which calls some class method.

That initial setup works as designed.

Hello,

I've got a table with many attributes and data. There is 10 000 000 registrations approximatly.

I need to make a research on this table with filters, paging, and order.

You can see an example of my SQL request :

SELECT * FROM ( SELECT TOP ALL * FROM ANCV_Data.Titre WHERE etatTitre = 'Emis' ORDER BY numRemise desc) v WHERE %vid BETWEEN 1 AND 25

Cause there are many data on my table, my SQL req is too long if I don't have index on my attributes BUT there are many associations possible...

SQL gateway.

It is not "compiling" correct the properties(get; set;) in the class, and generating 2 methods of :

GetuProperty and SetuProperty.

so it's not equivalent to standard methods interface handling.

How to delete this redundant task. Cannot press delete when logged in as _system

SQL gateway. 'Locking' problem.

while debugging, is there in Caché a command to 'unlock' the instance of a class ?

close class, and kill class is not enough.

same problem in %Activate link

for each debug I have to exit (Halt) the terminal,

make debug in C#

coming back , and re-load again in Caché.

I can refer to the TracerName for a given ImageFile object with the following syntax: obj.Study.Injection.GetAt(obj.InjKey).RadioTracer.TracerName

Is it possible to write an SQL statement to search the PET.ImageFile table to find a match based on the RadioTracer.TracerName?

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')"
