#Business Service #Object Data Model #Ensemble

Hello Everyone,

I have a healthshare web application with production, I try to make a field in basic setting of business service, and I would like to set a string to DISPLAYLIST and VALUELIST of that Property (string maked by query to sql table). I code the same here but it's syntax incorrect in DISPLAYLIST = GetTypeDisplay(), VALUELIST = GetTypeValue(). Someone know a best way to solved my problem? Thanks so much!

Class Demo.RegDataService Extends Ens.BusinessService
{

Property xmlTagName As %String(DISPLAYLIST = ",EDocument", VALUELIST = ",Demo.EDocument");

Property PrdType As %String(DISPLAYLIST = GetTypeDisplay(), VALUELIST = GetTypeValue());

Parameter SETTINGS = "PrdType:Basic";

Parameter ADAPTER = "EnsLib.File.InboundAdapter";

ClassMethod GetTypeDisplay() As %String
{
    s result = ""
    &sql(declare CC1 cursor for
    SELECT TypeName INTO :typename FROM Demo_Data.PrdType)
    
    &sql(open CC1)
    &sql(fetch CC1)
    
    while(SQLCODE=0)
    {
        s result = result_","_typename
        &sql(fetch CC1)
    }
    &sql(close CC1)
    q result
}

ClassMethod GetTypeValue() As %String
{
    s result = ""
    &sql(declare CC2 cursor for
    SELECT TypeId INTO :typeid FROM Demo_Data.PrdType)
    
    &sql(open CC2)
    &sql(fetch CC2)
    
    while(SQLCODE=0)
    {
        s result = result_","_typeid
        &sql(fetch CC2)
    }
    &sql(close CC2)
    q result
}

First, I thanks so much for your help Eduard Lebedyuk, I make a code the same below Classmethod and succeed get sql data to Setting. But I have a new issue, DISPLAYLIST and VALUELIST (label and value of select box in setting) have the same value. Do you know some way to set different value to label and value of select box? example: DISPLAYLIST = TypeName and VALUELIST = TypeId.

Here my ClassMethod:

 ClassMethod GetPrdType(Output pCaption As %String, Output pTopResults, Output pResults, ByRef pParms As %String, pSearchKey As %String = "") As %Status
{
set tStatus = $$$OK
kill pResults, pTopResults
set pCaption = ""
set tStatement = ##class(%SQL.Statement).%New()
set strSQL="SELECT TypeId,TypeName FROM Demo_Data.PrdType"
     set tStatus = tStatement.%Prepare(strSQL)
if tStatus '= 1 Quit $$$ERROR($$$GeneralError, "No SQL Tables found")
     set rset = tStatement.%Execute()
while rset.%Next(.tStatus) {
set pResults($i(pResults)) = rset.%Get("TypeName")
}
quit tStatus
}

Not an answer, but you can use LIST function to remove cursors and simplify code.

ClassMethod GetTypeDisplay() As %String
{
    &sql(SELECT LIST(DISTINCT TypeName) INTO :result FROM Demo_Data.PrdType)
    q result
}

ClassMethod GetTypeValue() As %String
{
    &sql(SELECT LIST(DISTINCT TypeId) INTO :result FROM Demo_Data.PrdType)
    q result
}

Actually I need cursors to do some more complex tasks but I can't show the source code of the company's project here, so just edit a bit to post in this topic. But thanks for your recomment

I just want to make a select box in setting of business service in production. Example, if I set value the same below it will have result look like image

Property PrdType As %String(DISPLAYLIST = ",Type 1,Type 2,Type 3", VALUELIST = ",T1,T2,T3");

Parameter SETTINGS = "PrdType:Basic";

So I would like to use a method, classmethod or param replace string in DISPLAYLIST and VALUELIST

I do not think that it's possible.

If display values are unique, you can build a unique index and use it to translate display value into id.

Do you want to get a list of possible values at runtime?

If so consider making your property object-valued:

Property PrdType As Demo.Data.PrdType;

If you do want to build a list once at compile time, then it is probably possible using method generators, but I would not recommend this approach.

You can subclass Ens.ContextSearch to provide dynamic settings lists. Docs.

Here's a sample class that adds ability to select XData in Ensemble setting.

/// Ensemble settings interface implementation
Class Package.EnsSearchUtils Extends %ZEN.Portal.ContextSearch
{

///Get class Xdata list.
ClassMethod GetXDatas(Output pCaption As %String, Output pTopResults, Output pResults, ByRef pParms As %String, pSearchKey As %String = "") As %Status
{
    Set tStatus = $$$OK
    Kill pResults, pTopResults
    Set pCaption = ""

    Set tClass = $get(pParms("class"))
    If tClass '= "" {
        Set tClassObj = ##class(%Dictionary.CompiledClass).%OpenId(tClass)

        For i=1:1:tClassObj.XDatas.Count() {
            Set pResults($i(pResults)) = tClassObj.XDatas.GetAt(i).Name
        }
    }
    Quit tStatus
}

}

For example to add a setting XSLTTransformation to BH that would allow me to choose on XData from my Package.XSLT class, I can specify SETTINGS parameter like this:

Parameter SETTINGS = "XSLTTransformation:Basic:selector?context={Package.EnsSearchUtils/GetXDatas?class=Package.XSLT}";
