Good morning Michael,

I haven't worked a lot with stored procedures but when I have worked with them, I did it like this.

TestSQLProc()
 New stmt,status,rSet,SQLQuery  

 SET SQLQuery = "SELECT PackageName.ClassName_ProcedureName('parameter')" 

 Set stmt = ##class(%SQL.Statement).%New()
 Set status = stmt.%Prepare(SQLQuery) 

 If status'=1 
 { 
    Set return="%Prepare failed:" Do $System.Status.DisplayError(status) Quit
 } 

 Set rSet = stmt.%Execute() While rSet.%Next()
 {
0 rSet."ColumnName"
 }    

Q

I think that your problem is that you're trying to get information using Call instead of Select.

I hope it helps you.

My best,

Good morning,

Sorry, I was wrong when writing the question, effectively what I am receiving is a empty string and what I want to store is an null.

David,
I have been trying to overwrite the Normalize method but it is not working for me, maybe I am not overwriting the method well

ClassMethod myPropertyNormalize(%val As %CacheString) As %String [ CodeMode = generator, ServerOnly = 1 ]
{
str=""
//s code="%val" //i %parameter("TRUNCATE"),%parameter("MAXLEN")'="" s code="$e(%val,1,"_(+%parameter("MAXLEN"))_")"
//$$$GENERATE(" Q "_code)
$$$GENERATE(" Q "_$tr(code,$c(0),""""))
QUIT $$$OK
}

I am doing it right? (I guess not xD )

Thanks!.
