To send an HTTP request using the Content-Type: application/x-www-form-urlencoded, you can use the %Net.HttpRequest class in ObjectScript. Below is an example of how to create and configure the request:

  1. Create an instance of %Net.HttpRequest.
  2. Set the required properties, such as Server, Port, and Https.
  3. Set the ContentType to "application/x-www-form-urlencoded".
  4. Add form data to the request using the InsertFormData method.
  5. Call the Post method to send the request.

Here is an example ObjectScript code:

Set httpRequest = ##class(%Net.HttpRequest).%New()
Set httpRequest.Server = "your.server.com"
Set httpRequest.Port = 443
Set httpRequest.Https = 1
Set httpRequest.ContentType = "application/x-www-form-urlencoded"
Set httpRequest.ContentCharset = "utf-8"

// Add form data
Do httpRequest.InsertFormData("key1", "value1")
Do httpRequest.InsertFormData("key2", "value2")

// Send the POST request
Set sc = httpRequest.Post("/your/endpoint")

// Check the response
If sc $$$ISOK {
    Write httpRequest.HttpResponse.Data.Read()
} Else {
    Write "Error: ", sc
}

Make sure to replace placeholders like "your.server.com" and the endpoint with actual values. In the example, form key-value pairs are added with the InsertFormData method [1][2].

You can use sandbox capabilities in the InterSystems IRIS Data Platform as an analytics sandbox. It provides a single tool for integration purposes, such as creating DataOps applications, BI tools, and analytical processes. InterSystems IRIS allows you to work with various programming languages including Java, Python, .NET, Node.js, and ObjectScript, and supports performing analytics and data visualizations directly within the platform [1].

You can retrieve and analyze SQL query execution plans programmatically and through interactive commands using InterSystems tools. Here are the approaches available:

  1. EXPLAIN Command:
    Use the EXPLAIN command in SQL to display the query execution plan for a SELECT query without actually executing the query. Example:

    SQL]USER>>EXPLAIN SELECT Name FROM Sample.MyTable WHERE Name='Fred Rogers'

    This command also allows for generating performance statistics with EXPLAIN STAT or alternate query plans with EXPLAIN ALT [1][2].

  2. SHOW PLAN Command:
    After executing your query, use the SHOW PLAN command in the SQL Shell to display its plan. Alternatively, you can set the execution mode to deferred to view the plan without running the query:

    SQL]USER>>SELECT Name FROM Sample.MyTable WHERE Name='Fred Rogers'
SQL]USER>>SHOW PLAN

    SHOW PLAN works for other statement types, including INSERT, UPDATE, and DELETE operations [1][2].

  3. SHOW PLANALT:
    The command SHOW PLANALT can display alternate execution plans for your query. This is useful for comparing different strategies proposed by the SQL optimizer [2].

  4. ObjectScript Method ($SYSTEM.SQL.Explain):
    Generate query execution plans programmatically using ObjectScript and the $SYSTEM.SQL.Explain() method. This can be integrated into your application workflows for automated analysis purposes [1][2].

These tools provide comprehensive ways to programmatically retrieve and analyze SQL query plans alongside their associated performance metrics, suppressing the need for SQL execution when desired and offering functionalities for debugging and optimization.
