SqlDataSource And Optional Stored Procedure Parameters
Oct 12, 2006
Everyone,
I have an application that pulls a list of employees into a web form. I use the same stored procedure to search for employees by various demographic characteristics, and have set all of these search parameters to be optional in the stored procedure.
Everything works fine when I pull the entire list (without declaring any select parameters). However, on my Search page, I have declared a number of SelectParameter (ControlParameters, to be specific) objects and mapped each one to its respective control (text boxes and a checkbox). When I attempt a search, the SqlDataSource does not select any records unless I specify an argument for ALL of the search parameters. If I omit even a single search value, the page just posts back and does not pull any information from the database. I have verified with SQL Profiler that it is not attempting to hit the database.
I have experimented with various declarations in the ControlParameter object, including the DefaultValue and ConvertEmptyStringToNull items. If I specify a non-empty string as a DefaultValue for all of the parameters, it will perform the query, but it does not query if I use an empty string as a default value - unless my user specifies a value in the form.
Any ideas?
Thanks
Tim

Hi all,
Can anyone please tell me what is the best way to handle optional parameters in a stored procedure which will ensure a good execution plan? I ask this as I have to create a stored procedure with six optional parameters and I'm getting a little concerned that, apart from the parameter issue, I'm going to have a lot of if else statements. Is there an easy way of doing all this?
Thanks

Hi I want to give the user the ability to search based on a number of criteria, however i do not know how to build my statement properly this is what i have so far;
ALTER PROCEDURE [dbo].[stream_StoreFind]
-- Add the parameters for the stored procedure here
@StoreName varchar(250),@subCategoryID INT
AS
SELECT Stores.StoreName ,StoreCategories.storeIDFROM Stores INNER JOIN
StoreCategoriesON
Stores.storeID = StoreCategories.storeID INNER JOIN
SubCategories ON
StoreCategories.subCategoryID = SubCategories.subCategoryID WHERE
My problem is how will i pass the parameters into the statement, taking into fact that sometimes they may be optional. Thank you

I have the following stored procedure:
Code Block
CREATE PROCEDURE udsp_td_queryowner
@state varchar(10) = NULL,
@businesstype varchar(20) = NULL,
@size int = NULL,
@sortorder varchar(20) = 'state'
AS
SELECT gl_t.state AS [State],
gl_t.business_type AS [Business Type],
gl_t.lowsize AS [Low Size],
gl_t.highsize AS [High Size],
e.InternetAddress AS [Owner]
FROM gl_territory gl_t JOIN employee e ON gl_t.employeenumber = e.EmployeeNumber
WHERE state = COALESCE(@state, state) AND
business_type = COALESCE(@businesstype, business_type) AND
COALESCE(@size, lowsize, highsize) between lowsize AND highsize
ORDER BY CASE WHEN @sortorder = 'state' THEN gl_t.state
WHEN @sortorder = 'business type' THEN gl_t.business_type
WHEN @sortorder = 'owner' THEN RTRIM(e.FirstName) + ' ' + RTRIM(e.LastName)
END ASC,
CASE WHEN @sortorder = 'low size' THEN gl_t.lowsize
WHEN @sortorder = 'high size' THEN gl_t.highsize
END ASC,
CASE WHEN @sortorder = 'statedesc' THEN gl_t.state
WHEN @sortorder = 'business typedesc' THEN gl_t.business_type
WHEN @sortorder = 'ownerdesc' THEN RTRIM(e.FirstName) + ' ' + RTRIM(e.LastName)
END DESC,
CASE WHEN @sortorder = 'low sizedesc' THEN gl_t.lowsize
WHEN @sortorder = 'high sizedesc' THEN gl_t.highsize
END DESC
What it allows me to do is enter in any number of the variables when running the stored procedure. For example, EXECUTE udsp_td_queryowner @state = 'IA' would give me everything in the table in the state of IA regardless of the other field values. Likewise, if I ran EXECUTE udsp_td_queryowner @state = 'KY', @size = 15 it would return the records that are in KY and the size of 15 is in the range of the low and high value.
If I run the first example in Query Analyzer I get 53 records from the data I have. It returns every record that has IA as the state. I run the same thing in Reporting Services and all I get is 3 records. Just the 3 records for the state of IA where the business type is either null or blank (I can't tell.) If I allow all of the variables to accept Nulls then it returns the correct data. However, I would like to find a better alternative because when the report is run it returns all of the records in the table initially and if they user wants to enter in any parameters they have to toggle off the null box for the corresponding paramter.
Any ideas?

Hi,
I'm developing a website using vwd express and I have created a GridView that bounds data from a stored procedure. The stored procedure takes one parameter. I tested it by using a default value and it works fine.
Now, instead of the default value i want to pass the current logged in user name as a parameter.
How do i do this. All the info i found around are for passing parameters to the select command of sqldatasource but i cant get it to work when i use a stored procedure.
Thanks, M.

I have a Gridview bound to a SQLDataSource that uses a Stored Procedure expecting 1 or 2 parameters. The parameters are bound to textbox controls. The SP looks up a person by name, the textboxes are Last Name, First Name. It will handle last name only (ie. pass @ln ='Jones' and @fn=null and you get all the people with last name=Jones. I tested the SP in Management Studio and it works as expected. When I enter a last name in the Last Name textbox and no First Name I get no results. If I enter a Last Name AND First Name I get results. I don't understand.
Here's the HTML View of the page. The only code is to bind the Gridview when the Search button is pressed.

Hello,
I'm having trouble executing a Stored Procedure when I leave the input field empty on a 'search' criteria field. I presume the error is Null/Empty related.
The Stored Procedure works correctly when running in isolation. (with the parameter set to either empty or populated)
When the application is run and the input text field has one or more characters in it then the Stored Procedure works as expected as well.
Code:
.
.
<td style="width: 3px">
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
</td>
.
.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" DataKeyNames="LogId" DataSourceID="SqlDataSource1"
Width="533px">
<Columns>
<asp:BoundField DataField="LogId" HeaderText="Log Id" InsertVisible="False" ReadOnly="True"
SortExpression="LogId" />
<asp:BoundField DataField="SubmittedBy" HeaderText="Submitted By" SortExpression="SubmittedBy" />
<asp:BoundField DataField="Subject" HeaderText="Subject" SortExpression="Subject" />
<asp:TemplateField>
<ItemTemplate>
<span>
<asp:HyperLink ID="HyperLink1" runat="server">HyperLink</asp:HyperLink></span>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<HeaderStyle BackColor="#608FC8" />
<AlternatingRowStyle BackColor="#FFFFC0" />
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:SmallCompanyCS %>"
SelectCommand="spViewLog" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ControlParameter ControlID="txtName" ConvertEmptyStringToNull="true" Name="name" PropertyName="Text" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
Stored Procedure:
ALTER PROCEDURE dbo.spViewLog (@name varchar(50) )
AS
SELECT * FROM log_Hdr WHERE (log_hdr.submittedby LIKE '%' + @name + '%')
RETURN
I have tried the 'convertemptystringtonull' parameter but this didn't seem to work.
Any guidance would be much appreciated.
Thank you

Hi,I have a stored procedure that takes 3 parameters. I am using a sqldatasource to pass the values to the stored procedure. To better illustrated what I just mention, the following is the code behind:SqlDataSource1.SelectCommand = "_Search"SqlDataSource1.SelectParameters.Add("Field1", TextBox1.Text)SqlDataSource1.SelectParameters.Add("Field2", TextBox2.Text)SqlDataSource1.SelectParameters.Add("Field3", TextBox3.Text)SqlDataSource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedureGridView1.DataSourceID = "SqlDataSource1"GridView1.DataBind()MsgBox(GridView1.Rows.Count) It doesn't return any value. I am wondering is that the correct way to pass parameters to stored procedure?Stan

I need to create a SP that will accept a varying number of input parameters. A form that the user completes has a several controls that serve to narrow the number of records returned. The more parameters given, the fewer rows returned. In the past I have accomplished this by dynamically building an SQL statement. I dosen't appear possible to pass an SQL statement in a variable to a SP. Any help or pointers would be appreciated.

Title speaks for itself really.
Is it possible to write a stored proc with optional parameters?
For example consider the following SELECT
SELECT FLD1, FLD2 FLD3 FROM TBL1
I'd like to add optional parameters to that statement so that if they wanted to narrow down the results by providing criteria for some fields they could - but didn't have to.
Is this possible?

I have a stored procedure that updates about a dozen rows.
I have some overloaded functions that I should update different combinations of the rows - 1 function might update 3 rows, another 7 rows.
Do I have to write a stored procedure for each function or I can I handle it in the Stored Procedure. I realise I can have default values but I the default values could overwrite actual data if the values are not supplied but have been previously written.
Many thanks for any guidance.

I've created a search page in my asp.net app that allows the user to enter optional parameters to narrow down the result set. It looks something like:Find all parts where: manuafacturer: <dropdownlist>ANY | manufacturer 1 |... </dropdownlist> model: <dropdownlist>ANY | model 1 |... </dropdownlist> cost: between <textbox> and <textbox> dollarsCurrently I create the SQL command on the fly building the WHERE based on what the user selects. For example if in the form above they select manufacturer = manufacturer1 model = ANY cost = between 10 and 15the WHERE string is ... WHERE manufacturer='manufacturer1' AND cost BETWEEN 10 AND 15Since the user doesn't care about model I leave it out of the WHERE. OK so here is my question. I want to move my queries to strored procedures however I'm not sure how to create the query since it changes based on what the user enters. Using the example above I'm assuming I can create one query with 4 parameters however what value would I use for ANY? parameter1 (manufacturer) = "manufacturer1" parameter2 (model) = ??? parameter3 (price low) = 10 parameter4 (proce high) = 15I see there is an ANY operator in T-SQL but it doesn't look like the right thing to use. Should I use LIKE '%'? Seems that using LIKE would result in addition overhead.ThanksSimon

Hi I have a textbox, and a dropdown list, What i am trying to do is give the user the option of searching based on both (textbox and dropdownlist) or one or the other(textbox or dropdownlist), What i am experiencing though is that when i enter a word into the textbox and select a value from a dropdownlist i get no search results even though the word is "like" the text in the database, it will only work when i type out the full word. What is wrong with my stored procedure, here it is;
SELECT S.storeID, S.storeName
FROM dbo.Stores AS SINNER JOIN dbo.storeCategories AS SC
ON S.storeID = SC.storeID left JOIN dbo.SubCategories AS SU
ON SC.subCategoryID = SU.subCategoryID
WHERE S.storeName like ISNULL(@storeName + '%', S.storeName)
AND SU.subCategoryID = ISNULL( @subCategoryID, SU.subCategoryID)

If I do this with a function and multiple inline sql statements, I could probably do it much easier, but here at work, sprocs are required, and I can't seem to stretch my knowledge and Google searches far enough to find the answer. Plus, I don't really think that creating 4 separate sProcs is the most efficient way of doing this
I need to select and return 8 columns from a table, but the problem is I need to feed the sProc parameters in such a way, that I can use different criteria in the Where Clause.
for instance, I need to combine these 4 select statements into one:1. Select (fields) from (table) Where TechID=@TechID and Status=@Status)2. Select (fields) from (table) Where TechID=@TechID3. Select (fields) from (table) Where OrdNum=@OrdNum3. Select (fields) from (table) Where CustNum=@CustNum
In all instances, the fields and the table are the same - how can I combine all these possible Where clauses (if/then - Select Case?) so that it's only one Stored Procedure?
(or, is this even possible?)

Hi,
I'm having an issue trying to send parameters to a SQLDatasource object. I"m creating it in code (and I need it to stay there) I have determined that the stored procs called with no parameters work fine. I start having problems when I have any parameters. Interestingly, it doesn't crash. It just fails to run (the onselected event never fires).
dsUser is a protected SQLDatasource property
repMain is a repeater on the aspx sheet
lstUser is a stored proc with one varchar(10) parameter called cSort
Here is my current code that will result in no called to StatementCompleted and no data. Pull cSort parameter from the proc and it works just fine. Obviously I'm setting it wrong.
string cSelect = "dbo.lstUser";
dsUser = new SqlDataSource();
dsUser .ConnectionString = GetConStr();
dsUser .SelectCommand = cSelect;
dsUser .SelectParameters.Add( "cSort", TypeCode.String, "" );
dsUser .Selected += StatementCompleted;
repMain.DataSource = dsUser ;
TIA,

Hi all,
From the "How to Call a Parameterized Stored Procedure by Using ADO.NET and Visual Basic.NET" in http://support.microsft.com/kb/308049, I copied the following code to a project "pubsTestProc1.vb" of my VB 2005 Express Windows Application:

Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim PubsConn As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS;integrated security=sspi;" & "initial Catalog=pubs;")
Dim testCMD As SqlCommand = New SqlCommand("TestProcedure", PubsConn)
testCMD.CommandType = CommandType.StoredProcedure
Dim RetValue As SqlParameter = testCMD.Parameters.Add("RetValue", SqlDbType.Int)
RetValue.Direction = ParameterDirection.ReturnValue
Dim auIDIN As SqlParameter = testCMD.Parameters.Add("@au_idIN", SqlDbType.VarChar, 11)
auIDIN.Direction = ParameterDirection.Input
Dim NumTitles As SqlParameter = testCMD.Parameters.Add("@numtitlesout", SqlDbType.Int)
NumTitles.Direction = ParameterDirection.Output
auIDIN.Value = "213-46-8915"
PubsConn.Open()
Dim myReader As SqlDataReader = testCMD.ExecuteReader()
Console.WriteLine("Book Titles for this Author:")
Do While myReader.Read
Console.WriteLine("{0}", myReader.GetString(2))
Loop
myReader.Close()
Console.WriteLine("Return Value: " & (RetValue.Value))
Console.WriteLine("Number of Records: " & (NumTitles.Value))
End Sub
End Class
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The original article uses the code statements in pink for the Console Applcation of VB.NET. I do not know how to print out the output of ("Book Titles for this Author:"), ("{0}", myReader.GetString(2)), ("Return Value: " & (RetValue.Value)) and ("Number of Records: " & (NumTitles.Value)) in the Windows Application Form1 of my VB 2005 Express. Please help and advise.

Hi, I'm having some issues with the SqlDataSource. I want to use it
to
populate a GridView, but using an optional parameter to filter the
results.
This is what I have right now (hopefully haven't made any typos
- can't
copy/paste):
<asp:SqlDataSource ID="test1" runat="server"
SelectCommand="SELECT * FROM
SomeTable WHERE (@MyParam IS NULL OR MyColumn =
@MyParam) ORDER BY
SomeColumn" ConnectionString="<%
ConnectionStrings:MyConnString %>" >
<SelectParameters>
<asp:ControlParameter Name="MyParam"
ControlID="DropDownList1"
PropertyName="SelectedValue" Type="String"
ConvertEmptyStringToNull="True"
DefaultValue=""
/>
</SelectParameters>
</asp:SqlDataSource>
<asp:DropDownList
ID="DropDownList1" runat="server" AutoPostBack="True">
<asp:ListItem
Selected="True" Value="">All</asp:ListItem>
<asp:ListItem>AnotherValue</asp:ListItem>
<asp:ListItem>SomeElse</asp:ListItem>
<asp:ListItem>Whatever</asp:ListItem>
</asp:DropDownList>
<asp:GridView
ID="GV" runat="server" DataSourceID="test1"
AutoGenerateColumns="False"
DataKeyNames="SomeID"
<columns>
<asp:BoundField
DataField="SomeColumn" HeaderText="A Title"
SortExpression="SomeColumn"
/>
(more bound columns here...)
</columns>
</asp:GridView>
When I test the SQL query in
the query designer it works (returns only rows
having the value passed as a
parameter when one is specified, otherwise it
returns all rows), so it seems
like that part is OK. The "All" (as in
"return all"/no filtering) entry in
the DropDownList has a value of a zero
lenght string, and the
ControlParameter has the convert empty string to null
to true (and the
default value is the same), so it should get converted to a
null when "All"
is selected, hence returning all rows. But it doesn't work.
It works fine for
all the entries with text, but the zero lenght string
somehow doesn't work -
I get no results at all instead of it returning all
rows (but the query
itself worked fine when I tested it).
What am I missing? I just can't
find what I'm doing wrong. Any ideas/hints?
(I also need to do the same with
an ObjectDataSource, so hopefully I can get
this to work!) I can't think of
an easy way to find out if the zero lenght
string gets converted to a null or
not (I've even tried adding OR @MyParam =
'' to the query and it still didn't
work....) Right now I'm stuck....
(Also posted this question on microsoft.public.dotnet.framework.adonet newsgroup)
Thanks a lot in advance for the
replies!

Can someone help me with this issue? I am trying to update a record using a sp. The db table has an identity column. I seem to have set up everything correctly for Gridview and SqlDataSource but have no clue where my additional, phanton arguments are being generated. If I specify a custom statement rather than the stored procedure in the Data Source configuration wizard I have no problem. But if I use a stored procedure I keep getting the error "Procedure or function <sp name> has too many arguments specified." But thing is, I didn't specify too many parameters, I specified exactly the number of parameters there are. I read through some posts and saw that the gridview datakey fields are automatically passed as parameters, but when I eliminate the ID parameter from the sp, from the SqlDataSource parameters list, or from both (ID is the datakey field for the gridview) and pray that .net somehow knows which record to update -- I still get the error. I'd like a simple solution, please, as I'm really new to this. What is wrong with this picture? Thank you very much for any light you can shed on this.

Good day,
I have an issue on constructing dynamic WHERE conditions that use OPTIONAL parameters.
SP_SOMETHING (
1) @DateFrom datetime,
@DateTo datetime,
2) @Param1 char(8),
3) @Param2 char(3),
4) @Param3 tinyint
)
I would like to use a where clause that can make use of any combination of the 4 parameters (the two dates should be together)
1 2 3 4
/ x x x
x / x x
x x / x where x = not supplied
/ = supplied a value
(and so the list continues)
Can anybody assist me or give me insights on how to go about this complicated WHERE construct without listing all the probable combinations of the supplied parameters in series of IF statements.
thank you

On many reports I have optional parameters, for example if the employee is filled in it will run for that employee but if it's null it runs for all employees. Which is the best way to handle this?
The two options I am currently looking at are:
select * from employee where (employee.id = @EmpID or @EmpID is Null)
select * from employee where isnull(@empID, employee.id) = employee.id
Anyone else have a different solution?
Currently we use the OR approach and I wanted to see if anyone had any thoughts before switching to using IsNull, which seems a bit better.

I am using Oracle 7.3 against SSRS. I have created an inline query with 7 unnamed parameters. I have named them in SSRS parameters window and selected NULL and ALLOW BLANK check boxes for all the parameters.
a.)
What I think should happen is: I should be able to pass the combination of parameters NOT all of them, because I have selected NULL and Blank check boxes. But in my case the query is not giving me any results if I pass 2 of 7 parameters. I can see the results only when I pass all 7 parameters.
Please Help me...
b.)
Is there a way I can create a Dynamic WHERE condition using ORACLE 7.3 as database and OUT REF cursor as out parameter for generating parameters. An Example would be great.......
I am much familar with SQL Server and creting a dynamic query is no problem. Because of this new assignment in Oracle 7.3 I am pulling my hair to solve this perticlaur problem...

I'm rewriting a T-SQL function that is called "Proper Case" which takes in a sentence and returns the sentence with the first letter of each word capitalized.
The new CLR(C#) function implements new functionality where it can take a string and turn it into a properly cased string, sentence cased string, lower cased, upper cased, and toggle cased.
The function takes in one parameter, the string, and the casing type, a string also. I want the casing type to be optional where if it's not passed in it defaults to "proper". The reason why I want this is so that I can easily replace the existing T-SQL function without having to add an extra parameter to each call to make life easier.
I know you can do it for SQL stored procedures, but I seem to be having trouble with the function.
Things I've tried:
1) Overloading the function in C# doesn't work because SQL functions don't like overloaded functions.
2) Attempting to set a "default" value to the parameter.
a) casingType nvarchar(4000) = 'proper'
b) default casingType nvarchar(4000) = 'proper'
Any ideas would be greatly appreciated. Thanks!

Is there a way to create optional parameters in Reporting. For example, I have two tables Region and Country, with drop downs in report displaying the list of each. The stored proc for Country list expects an input parameter RegionID but does NOT require one for the result set to be fetched. The stored procs run fine in sql, but when run with the report, the designer always complains that the RegionID Parameter must be provided for the Country DataSet/List to be populated. Is there a way to create this RegionID parameter as optional such that the country list is populated with all rows in the Country table if no RegionId is provided, and filters if a RegionId is provided??
here is some code that I am using my stored procs
Code Snippet
For Regions
SP1
Create Proc... spGetRegions
Begin...
Select RegionID, RegionName From Region
Order By RegionName
End
Code Snippet
For Countries
SP2
Create Procedure dbo.spGetCountries
@RegionID int = NULL,
AS
Begin
Select CountryID, CountryName From Country C
WHERE C.RegionID = CASE WHEN @RegionID is null THEN C.RegionID ELSE
@RegionID END
ORDER BY C.CountryName
END
