If you write a stored procedure to "SELECT MAX" from a table and the answer is null since the table is empty, how is the null answer returned to the program from the stored procedure? Do you actually get the letters "NULL" or do you just get a space? How should you define your variable in your program?
Thanks in advance!
My stored procedure displays two result sets. How can i use that result sets in my 3-tier application. I want to bind first resultset to repeater control and second to label control. I am using SqlDataReader...

View 4 Replies View RelatedVS.NET 2005 automatically deploys a CLR stored procedure when you start a project with debugging. However, if the CLR stored procedure attempts to access external resources you will get a message stating:
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've isolated this to being because the CLR stored procedure does not have the EXTERNAL_ACCESS permission set.
Is there a security attribute that can be used to decorate the CLR stored procedure code so that VS.NET 2005 will register the CLR stored procedure with the correct permission set?

I have a stored procedure like the following. This returns 2 result sets, however i only want it to return 2nd (SELECT SomeField FROM SomeTable). How is this done? Note - it is not possible to change 'SomeSPThatReturnsAnIntAndAResultSet '
CREATE PROCEDURE [dbo].[SomeSP]
@SomeParam int
AS
BEGIN
SET NOCOUNT ON;
declare @SomeScalar int
exec @SomeScalar = SomeSPThatReturnsAnIntAndAResultSet @SomeParam
if @SomeScalar = 0
BEGIN
SELECT SomeField FROM SomeTable
END
END
Greetings
I have a SQL Server stored procedure that performs several queries and therefore returns several "result sets" at any one time.
Wiring it up via ADO.NET I populate a DataSet with a number of items in the Tables collection - which is great - and I can give each item a name for identification purposes once the DataSet is populated.
But I'd like to know if there is some way I can set the names of each result set *within the text of the stored procedure*, i.e. before the DataSet gets populated.
Any help greatly appreciated.

I have a novice question. How does one suppress result sets returned from a stored procedure?
I have created a procedure which makes use of multiple stored procedures . The purpose of this procedure (lets call it procA), is to count the rows returned from other procedures. The €œOther€? procedures will return rows having an unknown number of columns. I would like to limit any changes which may be needed to be made to the €œOther€? procs.
Once procA has collected all of the information (@@rowcount) from the inner procedures, then it will return a result set having several columns €“ mainly the subProcedure name and number of rows returned.
The purpose of procA is to query several subsystems and identify which ones need attention.
Cursor While Loop
exec @ProcName @ObjectName,@userID,@syncDate
set @recs = @@rowcount;
My c# program calls the sp as follows:
cmd = DataUtility.GetSQLCommand();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FetchAdminData";
cmd.Parameters.AddWithValue("@userID", userAlias);
cmd.Parameters.AddWithValue("@adminDate",userDate);
reader = cmd.ExecuteReader();
I do not wish to iterate over each resultSet when I am only interested in the last one. Any suggestions?
Hi there everyone. I have a stored procedure called “PagingTable� that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see. This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server. The code might look something like this:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
The problem is the stored procedure actually returns two result sets. The first result set contains information regarding the total number of results founds, the number of pages and the current page. The second result set contains the data to be shown (the columns specified). In ‘classic’ ASP I did this like this.
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control. Any idea how I can accomplish two things:
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset
Hi all,
I want to know how to handle multiple result sets return from Stored Procedure? I know one way is to insert the result sets into the table, but the limitation is the result sets must have the same data structure. If the result sets have different data structure, how can I handle it.
Thanks,
I have a report based on our product names that consists of two parts.Both insert data into a temporary table.1. A single grouped set of results based on all products2. Multiple tables based on individual product names.I am getting data by calling the same stored procedure multipletimes... for the single set of data I use "product like '%'"To get the data for individual products, I am using a cursor to parsethe product list.It's working great except that I have no idea how to identify theresults short of including a column with the product name. While thatis fine, I'm wondering if there is something that is like a header ortitle that I could insert prior to generating the data that would looka little tighter.Thanks in advance-DanielleJoin Bytes!

I'm trying to write a stored procedure for a search criteria. A user will have few controls on ASP.Net webpage to enter/select the search criteria, based on which , it returns the data.
A Textbox( to enter Username), A Textbox (to enter Employee name),
A DropDownList (To select the profile. Its Id is sent as parameter) &
A DropDownList (To select status). This is where I am stuck.
The last dropdown has 3 list items
1. --All-- value is null/empty
2. Active value is 0
3. Blocked value is 1
Though the Database table will have only 0's and 1's for the status column, the user should be able to see all records when -all-- is selected.I also tried excluding the status parameter and its condition, but no luck either way.

Hello,I'm trying to pass a null object to a stored procedure to update a SQL Table boolean field with a null value. My SQL Table boolean column allows nulls.I'm using an InfoObject which has several properties all corresponding to fields in the SQL Table. One of those fields is a boolean. I create an instance of the InfoObject in my code and assigns values to the various properties. The boolean property in question (call it InfoOjbect.BooleanProperty) is not assigned anything. I then call my StoredProcedure passing the InfoObject to it (using the DotNetNuke DAL architecture) and the final result is the Table's boolean column is populated with a 0 and not a NULL. If I explicitly define the InfoObject.BooleanProperty = null.nullboolean before passing it to the Stored Procedure, the same thing happens. How do I pass a null to the SQL database for a boolean field? I've tried making InfoObject.BooleanProperty = dbnull.value but it won't let me do this saying "dbnull cannot be converted to a boolean." Do I have to explicitly create my InfoObject properties to allow for a null to be assigned to it?Any help would be greatly appreciated. I'm using the DotNetNuke DAL architecture passing my InfoObject through a dataprovider to the sqldataprovider which calls the SQL Stored Procedure to add the new record to the Table.Thanks in advance for any help.
View 2 Replies View RelatedIn a VB.NET script, I am adding the dbnull value to a parameter that will populate a smalldatetime column:
cmd.Parameters.Add("@unitHdApprove", System.DBNull.Value.ToString)
The stored procedure then defines the input as smalldatetime:
@unitHdApprove smalldatetime,
However, the result is that the record is inserted with 1/1/1900 as the date value, instead of <NULL>.
I'm guessing that this occurs because the conversion of a '' to date will return 1/1/1900, and VB requries the parameter value to be a string (at least with this syntax), so System.DBNull.Value.ToString really equals ''.
I've rewritten the proc to accept the date as a string instead, and then for each date, cast it to a smalldatetime or set it to null as is appropriate. But this is a really bulky way to do things with more than a few dates! Is there any way to change what is in my VB code so that the procedure will insert the actual null value?
Thanks,

I have a table which has 10 columns which make up the secondary key. 1or more of these columns can be set but the remaining columns in thesecondary key will be null. For example :id k1 k2 k3 k4 k5 k6 k7 k8 k9 k10 data-------------------------------------------------0 1 1 - - - - - - - - test01 1 1 1 - - - - - - - test12 1 1 2 - - - - - - - test23 1 1 3 - - - - - - - test34 1 1 3 1 - - - - - - test45 1 2 1 - - - - - - - test56 1 2 2 - - - - - - - test6Each row represents a node in a tree structure, the secondary keycolumns point to which node in the tree. The above example has onenode in tree branch 1, three nodes in tree branch 1-1, one node inbranch 1-1-3 and two nodes in branch 1-2.My question is how can I write a single stored procedure to returnonly the nodes in a given tree branch without needing logic based onlooking for NULL parameters. I have written the stored procedurebelow. If I want to retrieve all nodes in branch 1-1 (ie; test1, test2and test3) then I want be able to call :execute "mysp Test" 1, 1But this only returns a single record, test0. The reason for this isobvious if you look at the stored procedure. What I really need is wayof sayingexecute "mysp Test" 1, 1, NOT NULLso that it returns all records in branch 1-1 where Key3 is NOT NULLbut all subsequent keys are null, ie; Key4-Key10 are NULL. The storedprocedure must work with any number of secondary keys though, so Icould use it to call :execute "mysp Test" 1, 1, 3, NOT NULLwhich would retrieve test4.Can anybody help me out here?Thanks for reading.Here's the stored procedure as it stands :CREATE PROCEDURE [dbo].[mysp Test]( @key1 smallint,@key2 smallint=NULL,@key3 smallint=NULL,@key4 smallint=NULL,@key5 smallint=NULL,@key6 smallint=NULL,@key7 smallint=NULL,@key8 smallint=NULL,@key9 smallint=NULL,@key10 smallint=NULL ) ASselect * from TreePositionTestwherekey1=@key1 andkey2=@key2 andkey3=@key3 andkey4=@key4 andkey5=@key5 andkey6=@key6 andkey7=@key7 andkey8=@key8 andkey9=@key9 andkey10=@key10GO

Hello
I've written a stored procedure with 4 parameters
create procedure dummy
( @a int, @b int, @c varchar(50), @d varchar(50))
now from front end(I'm using c#.net)
I want to send the values according to some criteria
So in the process...I've only values for @a & @c ...
so In order to reduce the code of sending Null values explicitly to other parameters...
can't I set like default values for it so that If I don't send values to certain parameters it will have the default value or Null value.
like I want something like this:
create procedure dummy
( @a int NULL, @b int NULL, @c varchar(50) NULL, @d varchar(50) NULL)

I have a stored procedure like "select * from ThisTable"
I'm doing a dataread like:
Dim val as String = dateRead("column_from_ThisTable")
If the value in the column is not null everything works great, but if the value is null, instead of getting a value of "" which I expect, I get the column name??? In this case "column_from_ThisTable"
How do I make sure I get "" returned when the value in the column is db.null?
my stored procedure is
create procedure t1 (@a int,@b int,@c int,@d int,@e int,@f int)
as
begin
select no,name,department from emp where a = @a and b =@b orc =@c or
d = @d or e = @e or f = @f
end
my problem is while executing i may get null values as input to the stored procedure .
how to validate them ? any ideas .
are there any arrays.
if c and d are null then my condition would be
where a = @a and b =@b or e = @e or f = @f
how many loops shall i have to write.
Hello,
I have a report. I need to make a drop-down parameter optional. I've setup the parameter to use a dataset as its source, and I need to allow the value to be null. I've selected allow nulls check box, and I've even tried setting the default value to System.DBNull.Value. But, when the entry is not selected (blank), no data ever comes back. If the data is blank or null, my procedure works (I've tested it). How do I send a null value to the database through reporting services report? I was hoping to avoid creating a special query just for that purpose.
Thanks.
