DML Statements In Code Vs. Stored Procedures
Aug 4, 2005
Hi,We're having a big discussion with a customer about where to store the SQL and DML statements. (We're talking about SQL Server 2000)We're convinced that having all statements in the code (data access layer) is a good manner, because all logic is in the "same place" and it's easier to debug. Also you can only have more problems in the deployment if you use the stored procedures. The customer says they want everything in seperate stored procedures because "they always did it that way". What i mean by using seperate stored procedures is:- Creating a stored procedure for each DML operation and for each table (Insert, update or delete)- It should accept a parameter for each column of the table you want to manipulate (delete statement: id only)- The body contains a DML statement that uses the parameters- In code you use the name of the stored procedure instead of the statement, and the parameters remain... (we are using microsoft's enterprise library for data access btw)For select statements they think our approach is best...I know stored procedures are compiled and thus should be faster, but I guess that is not a good argument as it is a for an ASP.NET application and you would not notice any difference in terms of speed anyway. We are not anti-stored-procedures, eg for large operations on a lot of records they probably will be a lot better.Anyone knows what other pro's are related to stored procedures? Or to our way? Please tell me what you think...Thanks

Hi,
This is driving me up the wall,
I have used SQL for donkey's years, but never really used Stored Procedures, well, I am starting to migrate functions from a front end ASP.Net system, and utilising the stored procedures.
I have a problem with something I thought would be really basic, i am trying to use IF THEN statements within the stored procedure to change the WHERE elements based on the parameters passed to it.
Here is the script (copied from the modification screen)
USE [QP]
GO
/****** Object: StoredProcedure [dbo].[USERS_LIST] Script Date: 02/21/2008 21:50:31 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER Procedure [dbo].[USERS_LIST]
@SearchVarChar(100)
As
SELECT TOP 100 PERCENT dbo.Members.EntryID, dbo.Members.EntryDate, dbo.Members.Username, dbo.Members.Forename, dbo.Members.Surname, dbo.Members.Gender,
dbo.Members.DateofBirth, dbo.Members.LastAction, dbo.Members.AdminUser, dbo.ActiveMember_Status.Status, dbo.ActiveMember_Mobile.Value AS Mobile,
dbo.ActiveMember_Email.Value AS Email, dbo.ActiveMember_Location.Location1, dbo.ActiveMember_Location.Location2, dbo.ActiveMember_Location.Location3,
dbo.ActiveMember_Location.Location4, dbo.F_AGE_IN_YEARS(dbo.members.dateofbirth, GetDate()) As Age
FROM dbo.Members INNER JOIN
dbo.ActiveMember_Status ON dbo.Members.EntryID = dbo.ActiveMember_Status.UserID LEFT OUTER JOIN
dbo.ActiveMember_Location ON dbo.Members.EntryID = dbo.ActiveMember_Location.UserID LEFT OUTER JOIN
dbo.ActiveMember_Email ON dbo.Members.EntryID = dbo.ActiveMember_Email.UserID LEFT OUTER JOIN
dbo.ActiveMember_Mobile ON dbo.Members.EntryID = dbo.ActiveMember_Mobile.UserID
IF (@Search='Dowle')
WHERE (dbo.Members.Username = @Search) OR
(dbo.Members.Forename = @Search) OR
(dbo.Members.Surname = @Search) OR
(dbo.ActiveMember_Mobile.Value = @Search) OR
(dbo.ActiveMember_Email.Value = @Search) OR
(dbo.ActiveMember_Location.Location1 = @Search) OR
(dbo.ActiveMember_Location.Location2 = @Search) OR
(dbo.ActiveMember_Location.Location3 = @Search) OR
(dbo.ActiveMember_Location.Location4 = @Search)
END IF
ORDER BY dbo.Members.Username
The bit I am trying to do above isn't real, but the same error appears every which way I try.
Msg 156, Level 15, State 1, Procedure USERS_LIST, Line 14
Incorrect syntax near the keyword 'WHERE'.
What am i doing wrong?
Thanks

Is it true that replacing embedded sql statements (that insert/update and fetch data
from sql databases) by stored procedures improves overall respones time and SQL performance.
We have tons of embedded SQL statements in our Visual Basic modules and are debating whether replacing them by SQL Stored procedures
will really be worht the effort.
Any insights on this?
Thanks in advance. If possible, please reply to my e-mail.Thanks.

I cannot create temporarytables.i had not created the intial SQL statement, i am just trying toconvert it to a stored procedure which accepts thos parameters. thishas been a real headache for me, any help as always appreciatedgreatly.

Hi,
I am doing some research on sqljdbc 1.2. I have run into a few problems with the jdbc driver. I think it would be so much easier just to ask the expert here.
1. when to use CallableStatment, PreparedStatement, Statement for stored proc and why?
http://msdn2.microsoft.com/en-us/library/ms378046.aspx
talks about using Statements with Stored Procedures.
It says for stored Proc with no param, use Statement; for stored proc with only input param, use PreparedStatement; and for stored proc with output param, return status or update count, use CallableStatement.
Is there any special considerations to select which one to use, is there any performance differences? I assume we can always use CallableStatement for stored proc.
2. mutliple statements on one Connection
The JDBC spec allows multiple Statement on one Connection with no need to close the previous Statment. When Connection.close() is called, all the Statements and ResultSets will be closed too.
I tried with regular stored proc, it is fine of have a CallableStatement, then a Statement, without close the CallableStatment, all the Statements are executed with no error.
However, when I change the stored proc, using explicit transaction, i.e BEGIN TRANSACTION, and COMMIT TRANSACTION, the Statement failed and throw an error:
com.microsoft.sqlserver.jdbc.SQLServerException: Server failed to resume the transaction, desc: 3500000001.
at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerStatement.doExecuteStatement(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerStatement$StmtExecCmd.doExecute(Unknown Source)
at com.microsoft.sqlserver.jdbc.TDSCommand.execute(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeCommand(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeStatement(Unknown Source)
at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeQuery(Unknown Source)
When I add a CallableStatement.close() before the create the second Statment, then it worked. Is this a bug or something special needs to be set for stored proc with Transaction?
3. Statement.getGeneratedKeys
Under the hood, is it making another round trip to get the generatedkeys, or when the Statement created with Statement.RETURN_GENERATED_KEYS is excuted, the identity field is already retured with the Statement?
This method call works with regular insert Statement, but does not work for PreparedStatement calling a stored proc. Is this a bug?
Thanks in advance,
jessica

I have nested a Stored Procedure within a stored procedure. The nested stored procedure ends in a select statement. What I'd like to do is either capture the results of the select statement (it will be 1 row with 3 columns, I only need the contents of first column), or suppress the select statement from displaying in the final results of the Stored Procedure it is nested in.
Is there any way to do either of those?

Hello,
Is it possible to execute DBCC statements remotely in destination servers through stored procedures existing in source server.
I don’t want to use isql, osql, openquery, openresultset because I have to pass user id or password.
I have linked the required SQL servers using Linked servers.
If so please give some example.
Thanks in Advance,

In my SPs, I commonly have a situation, where a SELECT statement gets a single scalar value (e.g. SELECT Name FROM Employee WHERE id=@id) from a table.
Because the result is still a relation, I cannot process it directly or assign the result to a variable
(like set @name = SELECT Name FROM Employee WHERE id=@id)
So, how can I process the results of the statement in this case.
In some other cases, the result is actually a relation. And I want to iterate over all rows, processing each row's columns.
(I know this smells of ADO.NET, but how can I help it if I am coming from that background)...
The point is I want to do all this in T-Sql on server side!!!

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..

I have several stored procedures with a similar query. The SELECT clauses are identical, but the FROM and WHERE clauses are different.
Since the SELECT clause is long and complicated (and often changes), I want to place the SELECT clause in a separate file and then have the stored procedures include the block of text for the SELECT clause when they compile.
Is this possible? Looking through the docs and searching online, I don't see any way to do this.

Hi all,
I am in the position where I have to transfer data from an old database
schema to a new database schema. During the transfer process alot of
logic has to be performed so that the old data gets inserted into the
new tables and are efficiently done so that all foreign keys are
remained and newly created keys (as the new schema is Normalised alot
more) are correct.
Is it best if I perform all this logic in a Stored Procedure or in C# code (where the queries will also be run)?

This Might be a really simple thing, however we have just installed SQL server 2005 on a new server, and are having difficulties with the set up of the Store Procedures. Every time we try to modify an existing stored procedure it attempts to save it as an SQL file, unlike in 2000 where it saved it as part of the database itself.

WHERE (ePRN = @ePRN)
and the code behind which i have to write will be something like thiscmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@eName", ((TextBox)FormView1.FindControl("TextBox1")).Text);cmd.Parameters.AddWithValue("@ePRN", ((TextBox)FormView1.FindControl("TextBox2")).Text);

Using SQL 2005, SP2. All of a sudden, whenever I create any stored procedures in the master database, they get created as system stored procedures. Doesn't matter what I name them, and what they do.
For example, even this simple little guy:
CREATE PROCEDURE BOB
AS
PRINT 'BOB'
GO
Gets created as a system stored procedure.
Any ideas what would cause that and/or how to fix it?

Hi all,
In the VB 2005 Express, I can get the SqlConnection and ConnectionString of a Database "shcDB" in the Object Explorer of SQL Server Management Studio Express (SSMSE) by the following set of code:
///--CallshcSpAdoNetVB2005.vb--////
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
Public Class Form1
Public Sub InsertNewFriend()
Dim connectionString As String = "Data Source=.SQLEXPRESS;Initial Catalog=shcDB;Integrated Security=SSPI;"
Dim connection As SqlConnection = New SqlConnection(connectionString)
Try
connection.Open()
Dim command As SqlCommand = New SqlCommand("sp_insertNewRecord", connection)
command.CommandType = CommandType.StoredProcedure
.......................................
etc.
///////////////////////////////////////////////////////
If the Database "shcDB" and the Stored Procedure "sp_inertNewRecord" are in the Database Explorer of VB 2005 Express, I plan to use "Data Source=local" in the following code statements to get the SqlConnection and ConnectionString:
.........................
........................
Dim connectionString As String = "Data Source=local;Initial Catalog=shcDB;Integrated Security=SSPI;"
Dim connection As SqlConnection = New SqlConnection(connectionString)
Try
connection.Open()
Dim command As SqlCommand = New SqlCommand("sp_insertNewRecord", connection)
command.CommandType = CommandType.StoredProcedure
........................
etc.
Is the "Data Source=local" statement right for this case? If not, what is the right code statement for my case?
Please help and advise.

Error #1: Type 'SqlConnection' is not defined (in Form1.vb)
Error #2: Type 'SqlDataAdapter' is not defined (in Form1.vb)
Error #3: Array bounds cannot appear in type specifiers (in Form1.vb)
Error #4: 'DataSet' is not a type and cannot be used as an expression (in Form1)
Please help and advise.
Thanks in advance,

More Information for you to know:
I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly.
I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.

Hello all,
I am having a hard time getting this to work.
I am trying to build the where statement dynamically but it is a string and needs quotes. But the problem is the quotes are the problem. Are there any escape characters? or is there a way to make this happen??? Integers are easy keys because they do not need quotes.
SET @wheretmp = 'WHERE SourceIPID = BB901625-5E89-45D4-BD20-25730365A9DA'
Select * from tbl_All_Source @wheretmp
