Parameter Stored Procedures And Access Listboxes...Help!!!

Apr 22, 2001

I have upsized a complex Access 97 application to SQL Server 7, and want to substantially preserve the user interface design by using an Access 2000 project (*.adp) as the front end.

Most of the original Access queries accepted their parameters from screen form objects, and this works well using SQL 7 stored procedures as form recordsources.

However, Access 2000 does not seem to provide a way to tell a listbox or combo box how to pass a parameter value from a screen form object to its SQL 7 stored procedure rowsource.

These parametized listboxes are critical to the interface design.
Please help!!!

Sorry if I haven't choose appropriate forum for this question.

I have MSSQL05 beta. I know how to list all stored procedures in selected database (everything is in localhost). I need to list parameter names and types for selected stored procedure(s).
How can I do that or anything that can return parameter names and types?

It's windows application.

Having Difficulty With FormView, Stored Procedures And Insert Parameter

Feb 17, 2005

I setup the databse and Visual Web Developer to use
stored procedures when the insert command is used. The
database also uses the field UserName that I pass using a
SessionParameter within the InserParameter block from the
Membership.GetUser.Username from the aspnet_ tables.

My difficulty is when using the "Formview" as the body to
with which to insert (I wanted the design versatility of
FormView) I get an error: "system.formatExpression: Input
string was not in a correct format" when I leave the
textboxes empty and invoke the insert command. I first
assumed that the bound textboxes are not being converted
correctly when left blank, so I used the
ConvertEmptyStringToNull=True, with no success. I then
coupled that with the Type=[correct format] still with
the same error. Alas, my final attempt was to set
defaults in the "ALTER PROCEDURE" within the stored
procedure itself.

Any help would be most appreciated. Thanks.

Parameter Passing - Table Name & Column Name In Stored Procedures

Mar 9, 2001

How can a Stored Procedure use a variable table name and column name ?

The statement :-

SELECT @columnname FROM @tablename

gives error "Line 5: Incorrect syntax near '@tablename'."

I am passing the parameters 'tablename' and 'columnname' into the stored procedure, (in order to select a variable column from a variable table).

If I hard-code the tablename, then I get a column of output with just the name of the column I was trying to list, e.g. surname,

i.e. SELECT @columnname FROM employeetable gives :-

surname
surname
surname
surname
surname
surname


How can I get the procedure to accept a variable table name and column name ?


I thought one way to do it would be to use the 'EXEC' statement :-

SELECT @sql = 'SELECT '+ @columnname +' FROM '+@tablename
EXEC(@sql)

but this gives error : "Incorrect syntax near the keyword 'FROM' "

although the following table works :-

SELECT @sql = 'SELECT surname FROM '+@tablename
EXEC(@sql)

The problem seems to be mainly with variable column names.

Also, we don't really want to use the EXEC statement because it will not be compiled and will be slower. (Does anyone know by how much slower ?)


Any advice would be appreciated.

Kind regards,
Ian.

Execute SQL Task - Parameter Mapping For Stored Procedures

Dec 17, 2007

Hi ALL,

I have a Execute SQL Task to execute a stored procedure. It has no input and output parameters.

The stored procedure is defined as follows:


set ANSI_NULLS ON

set QUOTED_IDENTIFIER ON

go

CREATE PROCEDURE [dbo].[SetSLATimePriority]

AS

BEGIN

DECLARE @PriorityID tinyint,@MAXPriorityID tinyint

DECLARE @Priority NVARCHAR(MAX), @SLATime int

SET @PriorityID=1

SET @MAXPriorityID=0

SELECT @MAXPriorityID=MAX([Priority ID]) FROM [MTD Dashboard].[dbo].[Priority]

SET NOCOUNT ON;

WHILE @PriorityID<=@MAXPriorityID

BEGIN

SELECT @Priority= [Priority] FROM [MTD Dashboard].[dbo].[Priority]

WHERE [Priority ID]=@PriorityID

SELECT @SLATime= [SLA Time in hours] FROM [MTD Dashboard].[dbo].[Priority]

WHERE [Priority ID]=@PriorityID

UPDATE [MTD Dashboard].[dbo].[Remedy Dump-Filtered]

SET [SLA Time] = @SLATime WHERE [Priority] like @Priority

SET @PriorityID=@PriorityID+1

END

END


The Properties of Execute SQL Task are set as follows:

Result Set: None
Connection Type: OLEDB
SQL Source Type: Direct Input
SQL Statement: EXEC ? = [dbo].[SetSLATimePriority]
IsQueryStoredProcedure: True
ByPassPrepare: False

Parameter Mapping:

Variable Name : User::IntValue
Direction: ReturnValue
Data Type: Long
ParameterName: 0

I am getting the following error, when I run this package.

[Execute SQL Task] Error: Executing the query "EXEC ? = [dbo].[SetSLATimePriority]" failed with the following error: "Invalid parameter number". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

I am not able to figure out, where exactly the problem is.. Can some one please help me out?

Restricting Access To Stored Procedures

Oct 5, 2005

I'm going through the SQLSecurity Checklist I found at sqlsecurity.com. One of the points it says to "Restrict to sysadmins-only access to stored procedures and extended stored procedures that you believe could pose a threat." It also lists a bunch of stored procs and extended stored procs that you should consider restricting to sysadmins only. I was wondering if someone could give me some pointers on how to do this? I would like to write a script that I could run on every sql server 2000 install that would do this. How could I ensure that every user does not have access except the sysadmins?

Thanks,
Chris

Can't Access Properties On Stored Procedures

Jul 3, 2007

Hi. I have set up an instance of SQL 2005 on my local computer. I use MS SQL Server Management Studio to login into my 2005 instance via Windows login. When I expand "Stored Procedures" under "Programmability" of the Database I want and go to a stored procedure and right click, I don't see the "properities" selection.

I know it's there because I can get to it on other instances but I can't get to it on my local instance. I added my windows user to my Logins and then to my database users but it didn't help.

Can anyone please tell me what I need to do so I can access the properties of the stored procedures?



Thanks

Stored Procedures - Restricting Access

Dec 12, 2006

Hello everyone,

I have a design problem which I am hoping somebody can shed some light on.

I am running SQL Server 2000 using SQL authenticaiton (due to be changed to Windows authentication in the next 6 months). I have a table in my database which we shall call monthly. I want to restrict the ability to insert to the monthly table to 2 stored procedures (proc_abc & proc_xy) which I have written which do various other validation checks before it inserts the data into monthly.

Users with the Foo function assigned are able to execute proc_abc & proc_xy

I have written a VB application which can be used by users who are not familiar with SQL to be able to execute these stored procedures. (Must have Foo function in order to login to this application).

I want to restrict the ability to execute the stored procedures to users using the VB application only, and thus not be able to execute the stored procedure using Query Analyzer or such like for any Foo user.

Is there anyway I can do this?

One suggestion put to me is two split the functions. Have one function lets call it Top which can access the VB application and then have another function called Bottom which is able to execute the stored procedures. Only the VB app would have access to the Bottom credentials. But is this secure? Would I just hard code the credentials for the Bottom function user within the VB app? This doesn's seem a secure way of doing things to me.

Thanks for the help!

MS Access And Stored Procedures Or Views

Mar 13, 2008

Can Microsoft Access access a stored procedure on the SQL Server? If not, is there any way to assign a parameter to a view? I can link to a view in Access, but I cannot link to a procedure. I need to SELECT * from aTable WHERE ID = [@PassidInID]. Any way to do this through Access? The reason for this, is because I am trying to run an existing query (which is very busy - using other queries with queries in them etc.), and I keep getting an ODBC error. I am thinking that if I move the queries to the SQL Server, it may get rid of this error?
It's a 2-tier app I have. Tables on the server, forms, queries, and everything else in Access.
Thanks in advance - I hope.

SQL 2012 :: Parameter Error When Executing A Package With Built In Stored Procedures

Jul 23, 2014

I am using Excel VBA to run a stored procedure which executes a package using the built-in SQL Server stored procedures. The VBA passes two values from excel to the stored proc., which is then supposed to pass these "parameters" to the package to use as a variable within the package.

@Cycle sql_variant = 2
WITH EXECUTE AS 'USER_ACCOUNT' - account that signs on using windows authentication
AS
BEGIN
SET NOCOUNT ON;
declare @execution_id bigint

[code]....

When I try to execute the package, from SQL Server or Excel using the Macro I built, I get the following error:"The parameter '[User::Cycle]' does not exist or you do not have sufficient permissions." I have given the USER_ACCOUNT that runs executes the stored procedure permission to read/write to the database and the SSIS project folder.

Stored Procedures To Limit SELECT Access

Sep 17, 2007

Hi there,
I have a database table with a field to specify the username of records that particular user is allowed to access (read only).  I want to be certain the user does not have access to any other records.  So I'm using a stored procedure to query the table with "WHERE dbuser = USER".
My problem is that the stored procedure is returning an error that the table I'm querying cannot be found, and I suspect it is because the user does not have proper permissions to see those tables, even through the stored procedure.
So my question is, how do I grant the user sufficient access for this stored procedure to work without outright granting them select permission on the tables?
Much appreciated!

Running SQL Server Stored Procedures Through Access

Dec 13, 2004

Hi,
Can someone help me with this problem.
I have a stored procedure in SQL Server that updates a particular table. When I run it in SQL server Query Analyser, it works fine. But I want to invoke this stored procedure when I click a button on an MS Access Form. The code I'm using is:

Dim cn, cmd
Set cn = CreateObject("ADODB.Connection")
cn.Open "SQL" //Data Source Name
Set cmd = CreateObject("ADODB.Command")
Set cmd.ActiveConnection = cn
cmd.CommandText = "LoadApplicants" //Stored Procedure Name
cmd.CommandType = adCmdStoredProc
cmd.Execute

for some reason only a few records are updated everytime I click on the button. Is there any reason why this is happening?

Any advice would be greatly appreciated.

Passing Parameters To Action Stored Procedures Using ADO, In Access Project

Jul 20, 2005

There is a form in an Access Project (.adp, Access front end with SQLServer) for entering data into a table for temporary storing. Then, byclicking a botton, several action stored procedures (update, append) shouldbe activated in order to transfer data to other tables.I tried to avoid any coding in VB, as I am not a professional, but I havefound a statement in an article, that, unlike select queries, form's InputProperty can't be used for action queries. Therefore, parameters can bepassed to action stored procedure only by using ADO through VB.As I'm not very familiar with VB, I had to search in literature.So, this is a solution based on creating Parameter object in ADO and thenappending values to Parameter collection.Please, consider the following procedure I created for passing parametersfrom form's control objects (Text boxes) to a stored procedureDTKB_MB_UPDATE:Private Sub Command73_Click()Dim cmd As ADODB.CommandSet cmd = New ADODB.Commandcmd.ActiveConnection = CurrentProject.Connectioncmd.CommandText = "DTKB_MB_UPDATE"cmd.CommandType = adCmdStoredProcDim par As ADODB.ParameterSet par = cmd.CreateParameter("@DATE", adDBTimeStamp, adParamInput)cmd.Parameters.Append parSet par = cmd.CreateParameter("@BATCH_NUMBER", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@STATUS", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@DEPARTMENT", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@PRODUCTION", adVarWChar, adParamInput, 50)cmd.Parameters.Append parSet par = cmd.CreateParameter("@SAMPLING_TYPE", adVarWChar, adParamInput,50)cmd.Parameters.Append parcmd.Parameters("@DATE") = Me.DATEcmd.Parameters("@BATCH_NUMBER") = Me.BATCH_NUMBERcmd.Parameters("@STATUS") = Me.STATUScmd.Parameters("@DEPARTMENT") = Me.DEPARTMENTcmd.Parameters("@PRODUCTION") = Me.PRODUCTIONcmd.Parameters("@SAMPLING_TYPE") = Me.SAMPLING_TYPEcmd.ExecuteSet cmd = NothingEnd SubUnfortunately, when clicking on the botton, the following error apears:"Run-time error'-2147217913 (80040e07)':Syntax error converting datetimefrom character string."Obviously, there is some problem regarding parameter @DATE. In SQL Server itis datetime, on the form's onbound text box it is short date (dd.mm.yyyy)data type. I have found in literature that in ADO it should beadDBTimeStamp.So, what is the problem ?Greetings,Zlatko

Access 2007 Runtime: Stored Procedures As Record Source

Hello

In our company, after switching to Office 2007, Access 2007 runtime is installed on our general user machines.
Everything is just fine and beautiful, except that there is one issue with runtime:

Several forms in my Access Project use stored procedures in SQL Server 2000 as their record source. When i try to open the forms in Access 2007 Runtime on user machines, i receive an error that "The record source dbo.Myprocedure speified on this form or report does not exist ".
I use dbo.ProcName format and the forms open correctly in my full version Access.
What could be the problem?

Control Access To SQL Server 2005 Database Only Through Stored Procedures Issue

Apr 14, 2008


Hello,

I have a database (SQL 2005) with two schemas (dbo and s1) and with tables defined in dbo and tables defined in s1. The stored procedures are also defined in both schemas, some of them in dbo some of them in s1. Some of the stored procedures query tables from dbo and s1 at the same time.
I want to have a new db role with access to the database only through sps and no other access read/write to the tables. I created a new db role and granted execute permission to it and assigned a user to it.
When I execute stored procedure defined in dbo with query against dbo tables, it works as expected.
However, if I run stored procedure defined in s1 with query to table in dbo, I receive error about missing select permission for the table in dbo. I am not sure why, but I can assume there is an issue with the ownership chain.
I can grand read/write permission for the tables, but this will break our original requirement for limited access to the db only through sp.
The other option is to have another role r2, with read/write, privilege and to use EXECUTE AS r2 in the sp.

I would like to ask first why the error for missing select permission happens and is there another way to have role restricted to only execute permission for all stored procedures.

Thanks,
IT

Database Access Via COM Objects - V- Database Access Via Stored Procedures

Aug 17, 2000

We have been asked to look into using stored procedures with SQL Server 7.0 as a way to speed up a clients site. 99% of all the articles I have read along with all the books all say Stored Procedure should be used whenever possible as opposed to putting the SQL in your ASP script. However one of my colleagues has been speaking to Microsoft and they said that that they were surprised that our client wanted to use Stored Procedures as this was the old method of database access and that now he should really consider using COM objects for data access as itis much faster. Has anyone got any views on this or know of any good aticles regarding this matter ?

ADO - Cannot Access The Return Parameter Of A Stored Procedure On SQL Server 2005

Apr 18, 2007

Hello,



I am trying to access the Return Value provided by a stored procedure executed on SQL Server 2005. The stored procedure has already been tested and it returns the required value. However, I do not know how to access this value. I have tried appending a parameter to the command object using "adParamReturnValue" but that only returns an error. The code works fine without appending this parameter. I have tested it by grabbing the recordset and returning the first field.



To avoid any confusion, I'm not talking about adding an "output" parameter to the stored procedure. I just want to be able to access the return value provided when the procedure is executed. Below is some of the code I am using.



try{

pCmd.CreateInstance((__uuidof(Command)));

pCmd->ActiveConnection = m_pConnection;

pCmd->CommandType = adCmdStoredProc;

pCmd->CommandText = _bstr_t("dbo.GetFlightPlan");



............................ code here ........................................



pCmd->Parameters->Append(pCmd->CreateParameter(_bstr_t("AircraftID"),adChar,adParamInput,7,vAcId));

pCmd->Parameters->Append(pCmd->CreateParameter(_bstr_t("DepartureAerodome"),adChar,adParamInput,4,vDepAero));

pCmd->Parameters->Append(pCmd->CreateParameter(_bstr_t("DestinationAerodome"),adChar,adParamInput,4,vDestAero));

pCmd->Parameters->Append(pCmd->CreateParameter(_bstr_t("DepartureHour"),adInteger,adParamInput,2,vDepHour));

pCmd->Parameters->Append(pCmd->CreateParameter(_bstr_t("DepartureMin"),adInteger,adParamInput,2,vDepMin));



VARIANT returnVal;

returnVal.vt = VT_I2;

returnVal.intVal = NULL;

pCmd->Parameters->Append(pCmd->CreateParameter(_bstr_t("RETURNVALUE"),adInteger,adParamReturnValue,sizeof(_variant_t),returnVal));

//Get Return value by executing the command

//The return value should be the DB unique ID.



pCmd->Execute(NULL, NULL, adCmdStoredProc);

int uniqueId = returnVal.intVal;

//pRst = pCmd->Execute(NULL, NULL, adCmdStoredProc);

//GetFieldValue(0,pRst,uniqueId);



printf("The DB unique ID is: %i",uniqueId);

return uniqueId;

}

////////////////////////////////////////////////////////////////////////////////////////////
I try to do an ADO.NET 2.0-VB 2005 programming in my VB 2005 Express to get @percentage printed out in the VB Form1. I read some articles in the websites and MSDN about this task and I am very confused about "How to Work with Output Parameters & Report their Values in VB Forms": (1) Do I need the Form.vb [Design] and specify its properties of the object and classes I want to printout? (2) After the SqlConnectionString and the connection.Open(), how can I bring the value of @percentage to the Form.vb? (3) The following is my imcomplete, crude draft code:

Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes

Public Class Form1

Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=pubs;Integrated Security=SSPI;"

Dim connection As SqlConnection = New

SqlConnection(connectionString)

Try

connection.Open()

Dim command As SqlCommand = New SqlCommand("byroyalty", connection)

command.CommandType = CommandType.StoredProcedure
...................................................................
..................................................................
etc.
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
From the above-mentioned (1), (2) and (3), you can see how much I am lost/confused in attempting to do this task. Please help and give me some guidances and good key instructions for getting the output parameter printed out in the FORM.vb in my VB 2005 Express project.

Thanks in advance,
Scott Chang
