Inferring parameter type when passing DBNull

Hello,
how can I generate a SqlParameter with DBNull value if I don't know the column type? If I do not specify it, it defaults to string and the command fails if the column type is different.
The SQL server does not seem to worry that much about types if you include NULL in the statement directly, so is there a way how to achieve this using the parameters?
Thanks,
Jan

OK, well I was talking about setting the column value to Null *in* the stored procedure based upon what it has received from .NET. I'm not sure how the parameter type in ADO.NET is relevant in this instance. That is unless we're not
talking about the same thing.
Is there an issue with using optional parameters and defaulting a column value to Null? I don't think ADO.NET is going to be much help here.

"Missing parameter values " when passing parameter to subreport

i have a subreport embedded in main report.
sub report take a procedure with parameter.the main report does nothing but only holds many sub report.now i have to pass parameter from code to sub report.ive used the following code but it gives "missing parameter values" error
Any help??
   ParameterField paramField = new ParameterField();
        ParameterFields paramFields = new ParameterFields();
        ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
        paramField.Name = "@LabNo";
        paramDiscreteValue.Value = "1034";
        paramFields.Add(paramField);
        ParameterValues paramvalues = new ParameterValues();
       paramvalues.Add(paramDiscreteValue);
        paramField.CurrentValues.Add(paramDiscreteValue);
rptDocument.ParameterFields[0].CurrentValues = paramvalues;

does the sub report have parameters in it as well?
if the sp used for the sub report has parameters you need to pass them to the sub. i would probably remove the parameters from the sub and join the sub to the main by the parameter from the main to the field in the sub.

When/How to use - "search" parameter type in parameter like other types.

We recently upgraded BI Publisher to 10.1.3.4. I saw new parameter type "search" in parameter section, when creating report. whats the use of it? How to use it ? like other parameter type Text, Menu,Hidden, Date.
I couldn't find any help or release notes on this !
Thanks

I started looking into this parameter type when our drop-down for customer numbers went from 13,000 (manageable) to 45,000 (completely unmanageable).
I imagine this is supposed to mimic the effects of a "Long List" type LOV in Oracle Applications (as I had inquired about in [this thread|http://forums.oracle.com/forums/thread.jspa?threadID=895521&stqc=true|Large List of Values (LoV) hangs. Is there an equivalent for a long list?]), but performance-wise, "Search" does not seem to be any more efficient that using the "Menu" type LOV. Even with the help of having a partial string with a wildcard to match, the "Search" still takes too long to pull up to be of any use to us.

Well I posted a thread several weeks ago...see this thread below
trying to get used to sql*plus, running and creating a simple procedure
and someone made comments about the select query leading to sql injection. Now I am trying to understand the true case behind that. I have an idea made it is because of the first concatenation in the parameter or not. Not sure.

I have the same problem with mine... but im trying to find a way to fix it without restoring it...
but one fix is to shut it down completely ... then press and hold BOTH the power button and the home button .. hold both of those 4 ten seconds .. then release the power button but still hold down the home button .. and then it'll show something that says "connect to itunes" once u get it connected to itunes , click the restore button ... BEWARE THIS WILL WIPE OUT EVERYTHING ON YOUR IPOD!!! IT WILL RESTORE IT BACK TO FACTORY SETTINGS , AS IF U JUST BOUGHT IT !!!!! then it should work fine again .. but u will lose all data on there besides the things you have synced with itunes already..
Thats y im iffy with doing this , im trying to find a fix where i wont have 2 restore it but i dont think there is 1 :'(
good luck tho

I think SAP Query Manager can support the sub-query, kindly advise how to solve or other alternative way to solve this issue.
Thanks a lot.

Dear Thanga Raj K,
From your solution i can get my expected result, only within your solution you miss out the @ in line 32 for ToDate variable.
After i have added it, it working perfectly.
Thanks once again.

How to skip the spaces, ' etc when passing the parameter to srw.run_report?

Hi, I have got problem with passing parameter to srw.run_report. It seems it doesn't take the special symbols such as space, ', etc.. the statement is like:
srw.run_report('report=test1 p_name='| |:p_title);
if :p_title is "JOE", there is no problem to pass it, but if the :p_title is "JOE LI", then the value of the parameter can be passed to p_name.
Does any one know how to skip those special symbols in the string when passing it to srw.run_report. Thank you very much.
Joe

Hi,
Try this :
srw.run_report('report=test1 p_name='| |
chr(34)| |:p_title| |chr(34)

Sorry No, if your screen is broken, then you won't be able to unlock your phone.
You do backup your phone on a regular basis right?

What type of license should the user be assigned when passing transactions through the DI Server?

What type of license should the user be assigned when passing transactions through the DI Server?
We used to assign indirect access licenses to users that were just using the DI Server. We have one add-on developer that says that the user has to be a Profession license. Current environment is SAP B1 9.0 PL10. My understanding was that you could have up to 10 users assigned to a single DI Server license.

Hi,
From the license guide,
Indirect Access – has access to any SSP solutions (developed with the SAP Business One DI-API) only. The Indirect Access license is bundled with the DI server. Users who have an Indirect Access license can access a limited number of application forms, but cannot perform any functions with the SAP Business One application. Users who have an Indirect Access license can access an unlimited number of SSP solutions

Generic Method, How parameter type is determined

For method
<T> void fromArrayToCollection(T[] a, Collection<T> c) { ... } Why does
fromArrayToCollection(sa, co);passes and
fromArrayToCollection(oa, cs); fails.
oa - Object Array, Object[]
cs - Collection of String, Collection<String>
sa - String Array, String[]
co - Collection of Object, Collection<Object>
What are the rules governing the type of T inferred by compiler?

epiphanetic wrote:
I think you still haven't fully understood the issue.
I suggest, you also read the same generics tutorial by Gilad Bracha, section 6 from where I found this issue :). Ha! But I think it's misleading that that section uses arrays.
In his words "It will generally infer the most specific type argument that will make the call type-correct." Its also mentioned that collection parameter type has to be supertype of Array parameter type but no reason is given. I wonder why it fails to infer correct type in second case.Assume you passed in an array of Objects, and a Collection of Strings, and it was possible that T would then be Object. Using Bracha's example implementation:
static <T> void fromArrayToCollection(T[] a, Collection<T> c) {
   for (T o : a) {
      c.add(o); // correct
}Now imagine you had this code making use of it:
Object[] objects = {Integer.valueOf(1), "hi", new Object()};
Collection<String> strings = new LinkedList<String>();
fromArrayToCollection(objects, strings);
String string = strings.iterator().next(); //get first String, which is actually an IntegerTrying to get the first String would give a ClassCastException. So clearly that method cannot not be safely invoked.
The reason I think he's confusing things by using the array is because you might get it in your head that this would be OK:
static <T> void fromCollectionToCollection(Collection<T> one, Collection<T> two) {
   for ( T t : one ) {
      two.add(t);
Collection<Object> col1; Collection<String> col2;
doSomething(col1, col2);When clearly it's unsafe, as now your Collection of Strings might have a non-String in it! That's why I said this is more a nuance of generic arrays than of type inference proper.

IN,OUT and IN OUT Parameter Types

Dear All,
as per some book,
IN parameter uses Call by Reference
and OUT and IN OUT Uses Call by Value
we can use NOCOPY for Making OUT and IN OUT Call by Reference.
my small doubt is
when u r passing a reference of a Variable how oracle takes care that only IN Parameter are not allowed to change (in c and c++ we can say *para to access the variables) ,
i mean in case i use NOCOPY all parameter type are using CALL BY REFERENCE then how the "No Modify" is forced in case of IN Parameter.
Thanks for Reading Request.
Raj.

The pl/sql compiler will simply not allow you to have a stmt that assigns something to an "IN" parameter. It can fully be enforced at compile time.

Raw parameter type

Hi all,
my WD application call the RFC "CRM_ICSS_UPLOAD_SR_ATTACHMENT" for attach documents. But, the file content parameter is the RAW type. I send the byte[] value for this parameter, but when I try to open the file uploaded in transaction, the file is corrupted (the content doesn't open). I try to pass the file content. For txt files, its OK!, but to images and other files, the file is open, but this content is corrupted!!!
Any suggestions!?
Thanks,
Yuri.

CHAR is limited to 2k.
VARCHAR2 is limited to 4k.
You should be using CLOB if you're
saving XML strings.
