I am trying to call a stored procedure inside a SQL SELECT statement. Has anybody had to do this in the past? I have a SELECT statement in a Microsoft Access database and I need that SELECT statement to call the stored procedure in the SQL server. Any help would be appreciated

For Example.
If we have procedure name sprocCurrentPriority
select * from tablename where colmunname = exec sprocCurrentPriority
Hi All... I'm calling a stored procedure from C#. I'm sending it input parameters as follows:SqlCommand c = new SqlCommand("AddAuthor", myConnection);c.CommandType = CommandType.StoredProcedure;
c.Parameters.Add(new SqlParameter("@LastName", SqlDbType.VarChar, 100));c.Parameters["@LastName"].Value = "Last";
c.Parameters.Add(new SqlParameter("@FirstName", SqlDbType.VarChar, 100));c.Parameters["@FirstName"].Value = "First";
In my opinion, that works nice - and it's easy. The reference I'm using says I can also specify "output" parameters - instead of supplying a value, one needs to change a property called direction.
But my stored procedure doesnt return any output parameters per se, but it does return a value. That is the last statement in the stored procedure is "RETURN @@IDENTITY" - it returns the identity field after an INSERT... So how do I get that value back in my C# code?
Thanks for the help in advance. Happy 4th to all! : ) -- Curt
Hi,
I was wondering if someone can tell me why my sub for calling stored procedures doesn't work.The string strFinFileId is not null.
I keep getting the following error System.IndexOutOfRangeException: Total
Here's my sub.
'//get GrandTotal Protected Sub GetGrandTotal(ByVal finfileid As String) Dim myConnection As SqlConnection Dim connString As String Dim strFinFileId As String Dim strGrandTotal As Decimal
strFinFileId = finfileid connString = ConfigurationManager.ConnectionStrings("PMOConnectionString1").ConnectionString
myConnection = New SqlConnection(connString) 'you need to provide password for sql server myConnection.Open()
Dim sql1 As String
sql1 = "GetGrandTotal " & Convert.ToInt32(strFinFileId)
Dim myCommand As SqlCommand
'Response.Write(sql1) 'Response.End()
myCommand = New SqlCommand(sql1, myConnection)
Dim reader As SqlDataReader = myCommand.ExecuteReader() While reader.Read() strGrandTotal = reader.Item("Total") LabelGrandTotal.Text = strGrandTotal 'Response.Write(strFinFileId) 'Response.End()
End While reader.Close() myConnection.Close() End Sub
Cheers

I have a stored procedure written to update a table:
The stored procedure has the following parameters:
@Original_TypeID int,
@Type_Desc varchar(35),
@Contact_Name varchar(20),
@Contact_Ad1 varchar(25),
@Contact_Ad2 varchar(25),
@Contact_City varchar(10),
@Contact_Phone varchar(12),
@Contact_Fax varchar(12),
@Contact_Email varchar(35)
And I want to call this procedure when the "update" button is clicked, my code is:Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim myConnection As New SqlConnection(ConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString)Dim myCommand As SqlCommandDim UpdteParam As New SqlParameter()
myConnection.Open()myCommand = New SqlCommand("[dbo].[sp_Update_Types]", myConnection)
myCommand.CommandType = CommandType.StoredProcedure
????????????????????????myCommand.Parameters.Add(UpdateParam)
???????????myCommand.ExecuteNonQuery()
myConnection.Close()
End Sub
Can you please help me with the ????? areas? I don't know how to pass the parameters into the procedure, and also the second set of ??? s, I'm not sure if I am executing the command correctly.
Thank you.
I'm relatively new to SQL Server and I was wondering if there is any way to call a DLL from a regular stored procedure? I believe I've read that the extended stored procedure is a DLL and therefore should be able to call another DLL. Can this also be verified? We're looking to speed up some sections of Visual Basic code which does some heavy I/O work. I've also asked this once before but didn't get an absolute answer - can you write the extended stored procedures in Visual Basic or is C/C++ the only language supported right now?
Thanks.

Hi AllI was wondering if there is a way to call a stored procedure from insideanother stored procedure. So for example my first procedure will call asecond stored procedure which when executed will return one record and iwant to use this data in the calling stored procedure. Is this possible ?Thanks in advance
View 18 Replies View RelatedIs it possible to have a stored procedure in database A while callingit from database B and have it manipulate the tables in database B(whatever the calling database happens to be)?We have a large-scale app that uses many complex stored procedures,and as of now, we're copying the SPs to every new database that iscreated, and it will soon become a nightmare for propagating updatesand fixes.

I have a simple stored procedure:
create procedure sp_testres
@mult1 int,
@mult2 int,
@result int output
as
select @result = (10*@mult1) + @mult2
go
When I call it
declare @result int
exec sp_testres 5, 6, @result output
print @result
(Result is correctly shown as 56).
I then in C# wrote the following:
m_cmd.CommandText = "sp_testres";
SqlParameter param2 = new SqlParameter("@mult2", SqlDbType.Int);
param2.Value = 6;
SqlParameter param1 = new SqlParameter("@mult1", SqlDbType.Int);
param1.Value = 5;
SqlParameter param3 = new SqlParameter("@result", SqlDbType.Int);
param3.Direction = ParameterDirection.Output;
m_cmd.CommandType = CommandType.StoredProcedure;
m_cmd.Parameters.Add(param1);
m_cmd.Parameters.Add(param2);
m_cmd.Parameters.Add(param3);
m_cmd.ExecuteNonQuery();
This works and param3.Value holds the result value.
I also notice that I can supply the parameters in any order, and things work fine.
What I want to know is: can I call the stored procedure with parameters, where I haven't supplied the parameter name, and just rely on the parameter order matching instead?
Hello All,
We are trying to figure out how to make a stored procedure call and pass some inputs using C# and plain ADO. We are able to call an empty stored procedure but cannot pass parameters into a stored procedure.
Does anyone have sample code in C# whereby we can open a connection and pass inputs into a stored procedure? The following is a sample code we are using:
ADODB.Parameter param = new ADODB.Parameter();
param=cmd.CreateParameter("@StoreID", ADODB.DataTypeEnum.adInteger, ADODB.ParameterDirectionEnum.adParamInput,sizeof(int) , 9);
cmd.Parameters.Append(param);
ADODB.Recordset rsInv = cmd.Execute(out objAffected, ref objAffected,-1 );
In the above example, we create a parameter of type integer and try to add it to the ADO Command object. It is supposed to return a recordset. It returns a recordset with record count -1.
Sincerely,
Dwight Kulkarni
I am writing a set of store procedures (around 30), most of them require the same basic logic to get an ID, I was thinking to add this logic into an stored procedure.
The question is: Would calling an stored procedure from within an stored procedure affect performance? I mean, would it need to create a separate db connection? am I better off copying and pasting the logic into all the store procedures (in terms of performance)?
Thanks in advance

I have created a cursor using the following type of syntax:
DECLARE MyCursor CURSOR FOR
SELECT ID FROM tblEmployees
OPEN MyCursor
BEGIN
FETCH NEXT FROM MyCursor
END
CLOSE MyCursor
Instead of the SELECT statement (SELECT ID FROM tblEmployees), I actually have a very complex select statement. I have created a stored procedure to handle this select. However, I cannot find a way to call a stored procedure in place of the SELECT statement in the cursor. Is this possible? Thanks.

Hi guys, hoping one of you may be able to help me out. I am using VS 2005, and VB.net for a Windows application.
I have a table in SQL that has a list of Storedprocedures: Sprocs Table: SPID - PK (int), ID (int), NAME (string), TYPE (string)The ID is a Foreign key (corresponding to a Company ID), the name is the stored procedure name, and Type (is the type of SP).
On my application I need to a certain SP depending on the company selected and what page you are on. I have a seperate SP that passes in parameters for both Company, and Type and should output the Name value:
ALTER PROCEDURE [dbo].[S_SPROC] ( @ID int, @TYPE CHAR(10), @NAME CHAR(20) OUTPUT )AS
SELECT @NAME = NAME FROM SPROCSWHERE [ID] = @IDAND [TYPE] = @TYPE
Unfortunately I dont seem to be able to get the output in .Net, or then be able to fill my dataset with the Stored Procedure.Has anyone done something similar before, or could point me in the right direction to solving this problem.
ThanksPhil
Hi, all
I'm using Sql server 2000
I want to make select statement dynamically and return table using function.
in sp, I've done this but, in function I don't know how to do so.
(I have to create as function since our existing API..)
Following is my tials...
1.
alter Function fnTest
( @fromTime datetime, @toTime datetime)
RETURNS Table
AS
RETURN Exec spTest @from, @to
GO
Yes, it give syntax error..
2. So, I found the following
From Sql Server Books Online, Remark section of CREATE FUNCTION page of Transact-SQL Reference , it says following..
"The following statements are allowed in the body of a multi-statement function. Statements not in this list are not allowed in the body of a function: "
.....
* EXECUTE statements calling an extended stored procedures.
So, I tried.
alter Function fnTest
( @fromTime datetime, @toTime datetime)
RETURNS Table
AS
RETURN Exec master..xp_msver
GO
It doesn't work... syntax err...
Here I have quick question.. How to execute statements calling an extended stored procedures. any examples?
Now, I'm stuck.. how can I create dynamic select statement using function?
I want to know if it's possible or not..
Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?
Is it possible to call a stored procedure inside a select statement: I tried this , but is giving error "Incorrect syntax near the keyword 'execute'."
"
SELECT PC.ProductId
FROM ProductCategories PC
WHERE PC.CategoryID in ( execute get_category_hierarchies 1 )
"
where get_category_hierarchies is the stored procedure which expects an integer parameter.

Hi all. This has kept me up all night! I'm trying to populate a datgrid with multiple tables with relating keys in each table.
For ease, I've made the databases hopefully understandable.
DoctorsDB - (ID, Name, Phone)
FriendsDB - (ID, Name, Phone)
PetsDB - (ID, Name)
PeopleISawTodayDB - (MyID, MyName, DocID, FriendID, PetsID)
Now I need to generate a datagrid with the following details:
MyID, MyName, Doc's Name, Friend's Name, Pet's Name.
I have some success with the following code:
PROCEDURE dbo.PeopleISawTodayDB
@ID as Int
AS
BEGIN
SELECT
PeopleISawTodayDB.MyID, PeopleISawTodayDB.MyName, PeopleISawTodayDB.DocID, PeopleISawTodayDB.FriendID, PeopleISawTodayDB.PetID, DoctorsDB.ID, DoctorsDB.Name, FriendDB.ID, FriendDB.Name, PetDB.ID, PetDB.Name
FROM
PeopleISawTodayDB INNER JOIN
DoctorDB ON PeopleISawTodayDB.DocID = DoctorDB.ID INNER JOIN
FriendDB ON PeopleISawTodayDB.FriendID = FriendDB.ID INNER JOIN
PetDB ON PeopleISawTodayDB.PetID = Pet.ID
WHERE PeopleISawTodayDB.JobID=@ID
END
BUT it will only make a row appear if there are ID's in each of the PeopleISawTodayDB respective ID fields.
If I want to leave one blank (as in I didn't see that person that day), I would like it to still find the other details and populate the datagrid.
Can anyone lend a coding hand???? Cheers

Hello, I need to use a if statement in stored procedures.
What I need to know is the proper syntax because anything I try does not work.
I need to check if 24 hours passed:
datediff(hh, Users.LastLogin, GetDate())

Thanks =)!
This works great in a query:

INSERT INTO OUTHOUSE.OUTHOUSE.KCA_BLDGS_ACCES

But the stored procedure only creates ONE Use statement:
USE [KCADOWNLOAD]
...etc.
I assume I can run an SP utilizing two databases...
The SP fails because it hasn't got a clue what OUTHOUSE is...

I am trying to simulate the <sequence name>.nextval of oracle in SQL Server 2000.
The situation is that i need to be able to run programmatically INSERT statements. In Oracle I am able to do INSERT INTO TABLE_A (ID, NAME) VALUES (TABLE_A_SEQUENCE.NEXTVAL, 'MIKKO') in a single prepared statement in my code.
I know that to recreate this in SQL Server 2000 I need to create a stored procedure and table to set up a way to generate "the next value" to use in my INSERT. but the schema below forces me to do my insert in 2 steps (first, to get the next value. second, to use that value in the INSERT statement), since I cannot execute the stored procedure inside my INSERT statement.
Is there any way for me to generate values within my INSERT statement that would simulate Oracle's <sequence name>.nextval and allow me to execute my INSERT in 1 line of code?
TABLE

-- return an error if sequence does not exist
-- so we will know if someone truncates the table

Hi,
We use stored procedures to populate the properties of data layer objects. Is there any advantage or disadvantage (performance wise) of using "SELECT * FROM Table1" Vs
SELECT COLUMN1, COLUMN2, COLUMN3, ETC FROM Table1.
Using individual column names in the select store procedure is getting difficult to maintain for large number of columns or when columns are added or removed.
Thanks,
Suparna
Ok, I currently have a query which is basically doing the following:
Code:
SELECT ...
WHERE x IN (101,102...)
I have a couple of questions:
Firstly would making this to a stored procedure really make much of a difference to performance considering the WHERE IN clause.
Secondly how can I pass this list of values to use in the WHERE IN clause to the stored procedure. I tried nVarChar but really wasn't surprised when it didn't work... and can't really think of another clear way.
Thanks in advance,

Hello,
This is my foray into Stored procedures, so I'm hoping this is a fairly basic question.
I'm writing a stored procedure, in which I dynamically create an SQL statement.
At the end of this, the SQL statement reads like:
Code SnippetSELECT COUNT(*) FROM StockLedger WHERE StockCode = 'STOCK1' AND IsOpen = 1 AND SizeCode = 'L' AND ColourCode = 'RED' AND LocationCode IS NULL AND RemainingQty > 0
Now this statement works a charm, and returns a single value. I want to assign this count to a variable, and use it further on in the stored procedure. This is where the problems start - I cant seem to do it.
If I hard code a statement, like
Code SnippetSELECT @LineCount = COUNT(*) FROM StockLedger
that works fine (although it brings back a count of all the lines).
But if I modify the dynamically created SQL Statement from earlier on to:
Code SnippetSELECT @LineCount = COUNT(*) FROM StockLedger WHERE StockCode = 'STOCK1' AND IsOpen = 1 AND SizeCode = 'L' AND ColourCode = 'RED' AND LocationCode IS NULL AND RemainingQty > 0
it doesnt work - it complains: Must declare the scalar variable "@LineCount".
Just to clarify, when I say "dynamically created an SQL statement, I mean that by a bunch of conditional statements I populate a varchar variable with the statement, and then eventually run it exec(@SQLStatementString)
So, my question would be, how do I do this? How do I make a dynamically generated SQL statement return a value to a variable?
Hi,
I need to keep track of the number of hits on a particular page. Im using a stored Procedure
What I want to do is get the number of hits and increment it by one :)
ie: Sub Procedure should be like below
SELECT noOfHits WHERE pageName = 'bla bla'
noOfHits = noOfHits + 1 etc.
Also, some of the pages will be added and deleted all the time, so before I increment the noOfHits variable I need to check that the pageName 'bla bla' exists. AND if it doesnt I need to create a pageName called 'bla bla'
What I need to do in essence is:
1. Check that a particular row exists. if it doesnt create it.
2. Increment a value (by one) to a column in this particular row.
Phew. Hope you got that. Any ideas much appreciated,
Thanks,
Pete
