I am connecting to a MS SQL Server Database using JDBC. These columns can be up to 255 characters.

Scott Roth · Mar 7, 2025 go to post

I thought the EnsLib.JavaGateway.Service is its own JVM. I have many different JavaGateway Services build 1 for each database I connect to so I can make MS SQL Query/Stored procedure calls.

But you want to make sure the %JDBC Server is running at the Server Level as well.

Within a BP, you can create a Variable list, and just call

do context.<variable>.Insert(<value>)

and it will add it to the list. Now that I have that piece working, I need to figure out how to extract that list so I can create some logic around it.

Scott Roth · Mar 4, 2025 go to post

do I have to call

foreach(<field>)
{
  set list = $LB(<field>)
 }

or can I

foreach(<field>)
{
 set list= $LI(<field>,<counter>)
}

Nice comparison, also you have to take in account the processing speed as well. I found using Embedded SQL through a SQL Outbound Adapter can slow processing significantly down as it has to build the SQL in the connection to get results. I have a high-volume Business Process that required us to build a Stored Procedure on MS SQL instead of the Embedded SQL so that the SQL Server has the query already built.

Within our DTC...

With some help from the Developer community, below is a Function I wrote for our needs to take a Base64 and write it out to a PDF.

ClassMethod DecodeBase64HL7ToFileFaxing(base64 As %Stream.GlobalBinary, Ancillary As %String, FileName As %String) As %String
{
	set ArchDir = <directory>
	set ArchAncDir = ArchDir_Ancillary_"/"
	set FaxDateDir = ArchAncDir_$PIECE($ZDATE($HOROLOG,7)," ",1)_"-"_$PIECE($ZDATE($HOROLOG,7)," ",2)_"-1/"

	if '##class(%Library.File).DirectoryExists(ArchDir)
	{
		do ##class(%Library.File).CreateDirectory(ArchDir)
	}
	if '##class(%Library.File).DirectoryExists(ArchAncDir)
	{
		do ##class(%Library.File).CreateDirectory(ArchAncDir)
	}
	if '##class(%Library.File).DirectoryExists(FaxDateDir)
	{
 		do ##class(%Library.File).CreateDirectory(FaxDateDir)
 	}
	set Oref = ##class(%Stream.FileBinary).%New()

	$$$LOGINFO(FaxDateDir_FileName)

	set Oref.Filename = FaxDateDir_FileName

	Do base64.Rewind()
	While 'base64.AtEnd {
		set ln = base64.ReadLine()
		set lnDecoded = $system.Encryption.Base64Decode(ln)
		do Oref.Write(lnDecoded)
	}
	Do Oref.%Save()
	do ##class(%File).SetAttributes(Oref,33261,.return)
	set Oref = "" // Close file
	set PDFFilePath = "/Fax/PDFFiles/"_Ancillary_"/"_$PIECE($ZDATE($HOROLOG,7)," ",1)_"-"_$PIECE($ZDATE($HOROLOG,7)," ",2)_"-1/"_FileName
	return PDFFilePath
}

I can't recall if we ever went live with this conversion.

Thanks, I was able to resolve my issues with JDBC and using Active Directory Password Authentication through Microsoft Entra. Connecting using JDBC to MS Azure SQL through Microsoft Entra and Active

I published an article based on my findings...

I ended up putting statements into my BP that set the EnsLib.SQL.Snapshot variable = "" after use.

I am still working with WRC and Microsoft to determine where the issue is.

Scott Roth · Jan 9, 2025 go to post

According to Microsoft, I had to download the 12.8 driver. But that did not work either, Microsoft is saying I need to install Maven and POM.

We use the Gateway to make Queries and Stored Procedure calls from our Business Processes/Business Operations.

@Chandrasekar Angaiah

My Init is as follows..

Method OnInit() As %Status

{

  Set ..InitDSN = ..Adapter.DSN

  //Set ..Adapter.ConnectAttrs = "QueryTimeout:45" ; try this too just in case...

  Set ..%Row.MaxRowsToGet = -1

  Quit $$$OK

}

When I try to compile, I am getting a %Row does not exist in this class.

Thanks, this looks very helpful in the case where we are in EST, but Radiology reads might come from a CST.

I ended up writing a function with some help from the Developer community to do this. The function basically iterates through the the HL7 message and check it against a Data Lookup Table. I am in the office in two week and will share it once I am back in the office.

This could be useful to the other versions of IRIS as well. Folks who use IRIS for Health, Health Connect, and HealthShare might find this useful.

I haven't had a chance to fully dive into 2024.2 and heading out on Vacation for the Holidays. I will take a look again at this after the 1st of the year.

I have seen this before on SQL Outbound Operations when we have had to force stop the BO when it was trying to call/execute a Stored Procedure. The only way we have seen to get rid of the empty PIDs is to stop/start the namespace.

More than likely there is a Firewall in place that every call we make outside of the Medical Center goes through.

Using a Personal laptop which is not owned by OSU, I was able to see type ahead search results and return search results from the Documentation page.

I would double check your directory

my config for Red Hat 8 is the following...

#### BEGIN-ApacheCSP-SECTION ####
LoadModule csp_module_sa "/opt/webgateway/bin/CSPa24.so"
CSPModulePath "/opt/webgateway/bin/"
CSPConfigPath "/opt/webgateway/bin/"
CSPFileTypes csp cls zen cxw

<Directory "/opt/webgateway/bin/">
AllowOverride None

if your still having an issue I would suggest you talk with WRC

I went through the motions of creating a Foreign Server, and foreign tables to pull in MS SQL information in order to centralize a view that I had created on MS SQL Server and just pull it into IRIS.

After fumbling my way through the creation, I could query the tables, but if I would only query 1 column to pull into this sql statement, I would get an error.

I could not see the tables in DBeaver as I prefer to use it to write my sql statements.

As soon as I signed out of the Production, both the foreign server, and tables no longer exist.

Are Foreign tables a temporary thing?

I would like to create a view in IRIS so my team doesn't have to rely on others to pull the data and we could reference it instead of calling a JDBC lookup on MS SQL server.

I would also like to make the server, and tables available to all namespaces.

Can someone help, or should I contact WRC?

I have never used JSON before to execute queries with an EnsLib.SQL.OutboundAdapter, but I have executed using

..Adapter.ExecuteUpdateParmArray. I would assume it works the same way

Method DeleteProviderAddress(pRequest As osuwmc.CPD.DataStructures.DeleteProviderAddress, Output pResponse As Ens.Response) As %Status
{

  set query = "DELETE FROM ProviderAddresses where Address_k = ? and DoctorNumber = ?"


  set par = 2

  set par(1) = pRequest.AddressKey

  set par(2) = pRequest.DoctorNumber



  set tSC = ..Adapter.ExecuteUpdateParmArray(.nrows,query,.par)



  if 'tSC write " DeleteProviderAddress Failed ",tSC

  quit tSC

}

I already use Get("<column>") to pull the values, I was just looking for an easier way like with a Foreach loop

I went to previous versions of the documentation, and the search did not work there either.
