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

Hello everyone smiley

I have a server configuration in a CSP Gateway installed on a PC (let's call it S2) different from the main one (let's call it S1). This configuration allows me to access a web application that is installed on S1, from a client C asking S2 for this webapp. But for now it works only in HTTP between C and S2, and we would like to use HTTPS (as it already works between S2 and S1).

Hi, I am trying to transform a message to meet a third party specification, and would like to know if you can advice me on how to separate a single OBX segment into several segments based on a '.'

I would like to separate the segment where the . [marked in red] is into another OBX segment. So the next segment would be:

I am reviewing some code where the % sign has been used liberally to name arrays that are worked on by different methods within the same class. Apparently it is not good practice to name variables with a "%" sign as the first character because this could overwrite other similarly named variables from other developers, including ISC! Is there another way to make a variable public ?

For the FIleSpec on a file service can you use a multiple wildcard values like *CLINICALENCOUNTER*.xml?

Transaction suspencion

It’s often useful to make changes inside the current transaction, that would not be rolled-back if transaction is rolled-back. For example to do some logging.

This can be achieved by using global that is mapped to temporary database -- IRISTEMP. All globals that start with ^IRIS.Temp* are mapped to IRISTEMP by default. Problem with such approach is that IRISTEMP is cleaned on InterSystems IRIS restart, so this log is lost.

What else you can do is -- suspend transaction temporarily, do the logging, and then resume the same transaction.

I have a process that takes data from a CSV file (actually a record mapper object) and creates a nicely formatted JSON string I would love to send this along to a RESTful business operation. However no matter what I try, I continually get <INVALID OREF> errors when trying to populate the object that extends Ens.Request to give it the JSON string.

I can add strings, other objects, you name it - but stuffing a JSON formatted variable/object into another object I want to send someplace is proving to be an impossibility.

Cache Ensemble

Hello,

Working on to learn very basic CUSTOM Business Service which sends to a EnsLib.File.PassthroughOperation.

But operation is not writing to File and erroring out (No Stream contained in StreamContainer Request")'.

How do convert the object to STREAM and wrap in the StreamContainer so the operation does not error and write to a file.

Thanks.

About %objlasterror

%objlasterror is a useful reference to the last error.

Every time $$$ERROR is called, %objlasterror is set to a result of this call.

It's important in cases where you want to convert exception to status:

Try {
   //  quality code
} Catch ex {
   Set sc = $g(%objlasterror, $$$OK)
   Set sc = $$$ADDSC(sc, ex.AsStatus())
}

Because AsStatus calls $$$ERROR under the wraps, the order is important, first you need to get %objlasterror and convert exception after that.
