When To Use A Function And When To Use A Stored Procedure.
Oct 28, 2006
Hi,
I thought that procedures do not return a value: well they only return a 1 or 0 depending on whether the procedure executed correctly. Functions are what you're supposed to use when you want to get a result set of some sort: ie a table or a scalar value.
Apparently that is not the case becuase you can return values from procedures. I've attempted to find out what the differences are between the two and when it is appropriate to use a procedure and when it is appropriate to use a function but I'm still unsure. Can someone please tell me the difference.
Thanks.

Hi everybody, I am having trouble how to fixed this code. I am trying to supply the parameterinside a stored procedure with a value, and displays error message shown below. If I did not supply the parameter with a value, it works. How to fix this?Error Message:Procedure or function <stored proc name> has too many arguments specified.Thanks,den2005
Stored procedure:
Alter PROCEDURE [dbo].[sp_GetIdeaByCategory]
@CatId <span class="kwd">int</span> = 0
AS
BEGIN
SET NOCOUNT ON;
Select I.*, C.*, U.* From Idea I inner join IdeaCategory C on I.CategoryID = C.IdeaCategoryID inner join Users U on I.UserID = U.UserID Where I.CategoryID = @CatId Order By LastModifiedDate Desc
End

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.

Has anyone encountered this before?
Procedure or Function 'stored procedure name' expects parameter '@parameter', which was not supplied.
It seems that my code is not passing the parameter to the stored procedure.
When I click this hyperlink:
<asp:HyperLink
ID="HyperLink1"
Runat="server"
NavigateUrl='<%# "../Division.aspx?CountryID=" + Eval("CountryID")%>'
Text='<%# Eval("Name") %>'
ToolTip='<%# Eval("Description") %>'
CssClass='<%# Eval("CountryID").ToString() == Request.QueryString["CountryID"] ? "CountrySelected" : "CountryUnselected" %>'>
</asp:HyperLink>
it is suppose to get the country name and description, based on the country id.
I am passing the country id like this.
protected void Page_Load(object sender, EventArgs e)
{
PopulateControls();
}
private void PopulateControls()
{
string countryId = Request.QueryString["CountryID"];
if (countryId != null)
{
CountryDetails cd = DivisionAccess.GetCountryDetails(countryId);
divisionNameLabel.Text = cd.Name;
divisionDescriptionLabel.Text = cd.Description;
}
}
To my app code like this:
public struct CountryDetails
{
public string Name;
public string Description;
}
public static class DivisionAccess
{
static DivisionAccess()
public static DataTable GetCountry()
{
DbCommand comm = GenericDataAccess.CreateCommand();
comm.CommandText = "GetCountry";
return GenericDataAccess.ExecuteSelectCommand(comm);
}
public static CountryDetails GetCountryDetails(string cId)
{
DbCommand comm = GenericDataAccess.CreateCommand();
comm.CommandText = "GetCountryDetails";
DbParameter param = comm.CreateParameter();
param.ParameterName = "@CountryID";
param.Value = 2;
param.DbType = DbType.Int32;
comm.Parameters.Add(param);
DataTable table = GenericDataAccess.ExecuteSelectCommand(comm);
CountryDetails details = new CountryDetails();
if (table.Rows.Count > 0)
{
details.Name = table.Rows[0]["Name"].ToString();
details.Description = table.Rows[0]["Description"].ToString();
}
return details;
}
As you can see I have two stored procedures I am calling, one does not have a parameter and the other does. The getcountry stored procedure returns the list of countries in a menu that I can click to see the details of that country. That is where my problem is when I click the country name I get
Procedure or Function 'GetCountryDetails' expects parameter '@CountryID', which was not supplied
Someone please help!
Thanks Nickdel68

Hello people,
When I am trying to call a function I made from a stored procedure of my creation as well I am getting:
Running [dbo].[DeleteSetByTime].
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.TTLValue", or the name is ambiguous.
No rows affected.
(0 row(s) returned)
@RETURN_VALUE =
Finished running [dbo].[DeleteSetByTime].
This is my function:
ALTER FUNCTION dbo.TTLValue
(
)
RETURNS TABLE
AS
RETURN SELECT Settings.TTL FROM Settings WHERE Enabled='true'
This is my stored procedure:
ALTER PROCEDURE dbo.DeleteSetByTime
AS
BEGIN
SET NOCOUNT ON
DECLARE @TTL int
SET @TTL = dbo.TTLValue()
DELETE FROM SetValues WHERE CreatedTime > dateadd(minute, @TTL, CreatedTime)
END
CreatedTime is a datetime column and TTL is an integer column.
I tried calling it by dbo.TTLValue(), dbo.MyDatabase.TTLValue(), [dbo].[MyDatabase].[TTLValue]() and TTLValue(). The last returned an error when saving it "'TTLValue' is not a recognized built-in function name". Can anybody tell me how to call this function from my stored procedure? Also, if anybody knows of a good book or site with tutorials on how to become a pro in T-SQL I will appreciate it.
Your help is much appreciated.

Hi All,
I'll admit that I'm not the greatest at stored procedure/functions but I want to learn as much as possible. So I have two questions:
1) I had VS2005 autogenerate a sqldatasource that created Select/Insert/Update stored procedures. When Updating a record and calling the stored procedure, I want to query another table (we'll call it tblBatchNo) that has only one record, Batchno. I want to put that current batchno into the Update statement and update the record with the current batchno. Can someone point me in the right direction? Remember that I'm still a beginner on this subject.
2) Can someone provide any links to online tutorials on t-sql?
Thanks in advance.

Hello all,
I'm trying to construct a select statement in a stored procedure that filters based on the returned values of a number of functions. My function works fine, but when I try to call the function from the stored procedure I get an error.
I'm going to try explain the thought process behind what I'm doing. Hope I make enough sense.The purpose of the stored procedure is to perform a wildcard search on a tool. The tool contains a number of FK that link to different tables (e.g., manufacturer, vendor). So I'm creating functions that also search the manufacturer and vendor and return the matching IDs.
Example of tool SELECT statement:SELECT tool_number, tool_description
FROM tool
WHERE tool_manufacturer IN (UDFmanufacturer_SearchName(@search_string)
This gives me an error:'UDFmanufacturer_SearchName' is not a recognized built-in function name.
Function code (removed some wrapping code for simplicity):SELECT manufacturer_id
FROM manufacturer
WHERE manufacturer_name LIKE '%' + @search_string + '%'These statements both work if I run a independent query: SELECT *
FROM UDFmanufacturer_SearchName('mol') SELECT *
FROM tool
WHERE tool_manufacturer IN (SELECT *FROM UDFmanufacturer_SearchName('mol')) This code fails:SELECT *
FROM ato_tool
WHERE ato_tool_manufacturer IN (UDFmanufacturer_SearchName('mol'))
I'm stuck. I haven't been able to find anything that shows me where I'm going wrong. Any thoughts or suggestions are appreciated. Thanks,Jay

I have a select statement like this. Notice that I am doing the same calculation on different fields. Is it possible I can make this, in coding terms, a fucntion; so I can call it when I like (this query) and just provide the field.
Example: select field1, test_field = secs_to_hhmmss(TALK_TIME) from ...
SELECT dbo.date_table.real_date, dbo.time_table.hh,
COUNT(dbo.CALLDETAIL.id) as NumOfCalls,
TalkTime =
CASE WHEN CAST(SUM(TALK_TIME) AS INTEGER)/3600<10 THEN '0' ELSE '' END
+ RTRIM(CAST(SUM(TALK_TIME) AS INTEGER)/3600)
+ ':' + RIGHT('0'+RTRIM((CAST(SUM(TALK_TIME) AS INTEGER) % 3600) / 60),2)
+ ':' + RIGHT('0'+RTRIM((CAST(SUM(TALK_TIME) AS INTEGER) % 3600) % 60),2),
HoldTime =
CASE WHEN CAST(SUM(HOLD_TIME) AS INTEGER)/3600<10 THEN '0' ELSE '' END
+ RTRIM(CAST(SUM(HOLD_TIME) AS INTEGER)/3600)
+ ':' + RIGHT('0'+RTRIM((CAST(SUM(HOLD_TIME) AS INTEGER) % 3600) / 60),2)

Hey I have the following Stored Procedure
CREATE PROCEDURE spGetOrderCount
(
@search varchar(1000) = default
)
AS
SET NOCOUNT ON
/* Setup search string */
IF (@search <> '')
BEGIN
SET @search = 'WHERE' + @search
END
/* Create a temporary table */
CREATE TABLE #TempTable
(
row int IDENTITY,
totalCount int
)
/* Insert the search results into query */
EXEC
(
'INSERT INTO #TempTable([totalCount])' +
'SELECT COUNT(*) AS totalCount ' +
'FROM tblOrders' + @search
)
/* Extract the wanted records from the temporary table */
SELECT[totalCount],
RecordsLeft =
(
SELECT COUNT(*)
FROM #TempTable TI
)
FROM#TempTable
SET NOCOUNT OFF
RETURN
;
GO
And then the following function which specifies the where clause of the statement
function getOrderCount(strDate, strStatusList)
getOrderCount = 0
dim objRS, objSP, strWhereClause
if isDate(strDate) and len(strStatusList) > 0 then
'# Filter on order status
'# Filter on date clause
strWhereClause = "(tblOrders.orderDate >= " & sqlServerDate(strDate) & ")"
'#GET order count
Set objSP = SQLGetProcedure("spGetOrderCount")
SQLSetProcedureParam objSP, "search", strWhereClause
Set objRS = SQLExecuteProcedure(objSP)
if not objRS.eof then
getOrderCount = objRS("totalCount")
end if
'# Free resources
deleteRecordset(objRS)
deleteObject(objSP)
end if
end function
When I do this together I get the following error on my ASP Page
Microsoft OLE DB Provider for SQL Server error '80040e14'
Line 1: Incorrect syntax near '.'.
/sigma_eircommobdispatch/server/database.asp, line 235
And the print out of the resulting string from the function is
(tblOrders.orderDate >= CONVERT(DATETIME, '2007-7-13', 102))
If i remove the Where clause the statement works fine..
Any ideas

I seem to be getting tasks that I am not familiar with these days. I am a
guy that has coded it all in the asp page or in the code behind in .NET.
This problem is outlined below and I need a help / advice on doing this. I
had the flow of the 3 parts to it expanded below. A call is made to a Stored
Procedure, The SP then calls a user defined function that runs SQL, this
returns a 1 or 0 to the SP which then returns the value back to the call on
the asp page. This is a lot I know but it is the way the lead guy wants it
done. Any help so I can keep most of the hair I have left is appreciated :-)
Short list of process flow:
1. Form.asp calls to rx_sp_HasAccessToClient in SQL SERVER
2. rx_sp_HasAccessToClient then calls ab_HasAccessToClient
3. ab_HasAccessToClient runs SQL command on db and sends return bit back to
rx_sp_HasAccessToClient
4. rx_sp_HasAccessToClient then sends this back to the call in the Form.asp
page
5. Form.asp then checks the Boolean and if 1 then show or if 0 then deny.

This is not the correct syntax but is showing what I understand sort of how
this is to be done so far.

best solution for this stored procedure query.I'm getting the following error:
Column 'dbo.Applicants.submitted' is invalid in the select list because it is not contained in an aggregate function and there is no GROUP BY clause. Here is my select query:
Code:
SELECT DISTINCT DATENAME(MONTH, submitted) AS mon, MAX(submitted) AS SubmitDate
FROM dbo.Applicants
WHERE ((CASE WHEN MONTH(submitted) > 8 THEN YEAR(submitted) + 1 ELSE YEAR(submitted) END) = @AcYr)
ORDER BY SubmitDate
The submitted field is a date field.I don't want to add the submitted field to Group By as I want to group by month not date.Is there any solution to avoid grouping by date?

Hello all,I have spend quite some time now but don't manage tofind out how to have the srv_describe function workingproperly for target NUMERIC(x,x) and NUMERIC types.Already tried several alternatives like e.g.// ...PVOID pvdata1;strcpy((char*)pvdata1, "12345.6789");wsprintf(colname, "Score");srv_describe(srvproc, 1 /* column #1 */, colname /* column name */, SRV_NULLTERM /* column name ending */, SRVNUMERIC, (DBINT)sizeof(DBNUMERIC), SRVNUMERIC, (DBINT)sizeof(DBNUMERIC), pvdata1);srv_setcoldata(srvproc, 1, pvdata1);srv_setcollen (srvproc, 1, strlen((char*)pvdata1));// ...but obviously does not work, I get an empty resultset.I could only manage by converting the numeric valueto string from C and then sending only strings but theSQL side expects actually a number(x,x) and is a customer, in which case, I would never propose to be casting thething from TSQL.Any ideas how to do it? The documentation and examples isquite limited in this area.Thanks in advance,Best Regards,Giovanni

could you correct my code, if you know what is the problem?
thanks
My contract table DDL:
************************************************** ***
create table contract(
contractNum int identity(1,1) primary key,
contractDate smalldatetime not null,
tuition money not null,
studentId char(4) not null foreign key references student (studentId),
contactId int not null foreign key references contact (contactId)
);
My insert stored procedure is:
************************************************** *****
create proc sp_insert_new_contract
( @contractDate[smalldatetime],
@tuition [money],
@studentId[char](4),
@contactId[int])
as
if not exists (select studentid
from student
where studentid = @studentId)
begin
print 'studentid is not a valid id'
return -1
end
if not exists (select contactId
from contact
where contactId = @contactId)
begin
print 'contactid is not a valid id'
return -1
end
begin transaction
insert into contract
([contractDate],
[tuition],
[studentId],
[contactId])
values
(@contractDate,
@tuition,
@studentId,
@contactId)
/*Error Check */
if @@error !=0 or @@rowcount !=1
begin
rollback transaction
print ‘Insert is failed’
return -1
end
print ’New contract has been added’
commit transaction
return 0
go

Hi,
I'm trying to call a Stored Procedure from a Inline Table-Valued Function. Is it possible? If so can someone please tell me how? And also I would like to call this function from a view. Can it be possible? Any help is highly appreciated. Thanks

I have created a store procedure, but the requirement is function because by using this function we need to add columns in a table with SSIS.
I have tried to create function, but the error I am facing is select statement can not return data.
CREATE PROCEDURE SP_STAT_CURR
(
@I_NET_AMOUNT NUMERIC(10,3),
@I_DOCUMENT_CURR VARCHAR(3),
@I_TARGET_CURR VARCHAR(3)
[code]....
