I have a set of stored procedures that return a fixed list of columns from a fixed list of parameters.
Is it possible to use 1 Report file to display these reports, and just switch the stored procedure name at runtime within .NET code, or will this reset the parameter list and/or column list?
I have a column in a table, which have the stored procedure name stored in each row. Now, I need to execute each SP in the table dynamically. I'm trying to construct a SQL but not able to fire them!!
DECLARE @sql VARCHAR(MAX)
SELECT @sql = STUFF((SELECT '; GO EXEC ' + StoredProcedureName + '' FROM MyTable FOR XML PATH ('')),1,5,'')
print @sql
EXEC sp_executesql @sql
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?
I have a stored procedure. It can be executed like this
exec test @p = 1;
exec test @p = 2
exec test @p = n;
n can be hundred.
I want the sp being executed in parallel, not sequence. It means the 3 examples above can be run at the same time.
If I know the number in advance, say 3, I can create 3 different Execution SQL Tasks. They can be run in parallel.
However, the n is not static. It is coming from a table.
How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?
I think about using script task. In the script, I get the value of n, and the list of p, from the table, then running a loop with. In the loop, I create a threat and in the threat, I execute the sp like : exec test @p = p. So the exec test may be run parallel. But I am not sure if it works.
I have a need to create a database, and then populate it. However, thecode below doesn't work as I hoped it might (it creates the table inthe "master" database, which is Not A Good Thing). I know already(thanks Tony!) that if you use Dynamic SQL for the USE command, thenthe subsequent operations need to be Dynamic SQL as well, which is apity since there are over 11,000 lines of it and I don't really fancydebugging it!Does anyone have a cunning plan? In a nutshell, I would like to beable to:1. Create a new database with a derived name - as in the case below aname based on the year, though it might be month as well.2. Create and populate tables in this new database.These operations would ideally be running from a scheduled job.Any thoughts?TIAEdward====================================USE MASTERDECLARE @DBName VARCHAR(123)SET @DBName = 'MyTest_' + CAST((Year(Getdate())) AS Varchar)if not exists(select dbid from master.dbo.sysdatabases where name =@DBName)exec('CREATE DATABASE ' + @DBName)elseraiserror('Database already exists.',3, 1)EXEC ('USE ' + @DBName)if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[TestTable]') and OBJECTPROPERTY(id, N'IsUserTable')= 1)drop table [dbo].[TestTable]GOCREATE TABLE [dbo].[TestTable] ([TestID] [int] NOT NULL ,[Description] [varchar] (50) COLLATE Latin1_General_CI_AS NULL) ON [PRIMARY]GO

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.
Thank you in advance for any help on this matter
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?
Thanks,
Jason
I think I'm being a bit thick, but I just cannot figure out the proper syntax to call a stored proc on a SQL named instance I have. I've tried many variations, but here is the basic format of what I'm trying:
EXEC ServerInstance.DB.dbo.usp_fm_proc 1
It seems it doesn't like the as I get an error "Incorrect syntax near 'Instance'.
What am I missing here?
Hello,I was wondering if it is possible to dynamically execute a stored procedure; for example, in SQL, you can do:insert into Table1( id, name)select id, namefrom Table2Can you do something like:exec spProc @id = id, @name = namefrom Table1Or something like that? I know I can select a row at a time and execute, or write a program, but I was looking to see if there was an easier way.Thanks.
View 1 Replies View RelatedOkay. Scenario:
We as a company have several companies that request custom reports from us. However, the custom reports that they select will generally always have the same fields (and formulas) once they make up their minds on what works for them.
From what I know, Stored Procs are usually faster at running things unless the parameters are changing too drastically that they get passed.
This being the case, it would seem like a good case for creating a stored proc per report. This would alleviate the possability that the server chooses an execution plan that works great some of the time but the rest of the time run lousy.
So these thoughts being laid out, is there a good,nice,easy, convenient way to generate/alter a stored proc, either by another stored/extended proc, or by dynamic sql going to the server?
Or if not, is there some round-about yet effective way of doing this?
Thank you in advance for any help.

Hello All,
I have created SP in SQL 2K5 and make the where clause as parameter in the Sp. i am passing the where clause from my UI(ie ASP.NET), when i pass the where clause to SP i am not able to fetch the results as per the given criteria.
WhereClause from UI: whereClause="where DefectImpact='High'"
SQL Query in SP: SELECT @sql='select * from tablename'
Exec(@sql + @whereClause )
Here i am not able to get the results based on the search criteria. Instead i am getting all the results.
Please help me in this regard.
Thanks,

Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID, S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName', T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID FROM [Item].ItemDetails I INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID FROM [Item].ItemDetails IOr something like that... Any thoughts?

I have MSSQL 2005. On earlier versions of MSSQL saving a stored procedure wasn't a confusing action. However, every time I try to save my completed stored procedure (parsed successfully ) I'm prompted to save it as a query on the hard drive.
How do I cause the 'Save' action to add the new stored procedure to my database's list of stored procedures?

We recently upgraded to SQL Server 2005. We had several stored procedures in the master database and, rather than completely rewriting a lot of code, we just recreated these stored procedures in the new master database.
For some reason, some of these stored procedures are getting stored as "System Stored Procedures" rather than just as "Stored Procedures". Queries to sys.Objects and sys.Procedures shows that these procs are being saved with the is_ms_shipped field set to 1, even though they obviously were not shipped with the product.
I can't update the sys.Objects or sys.Procedures views in 2005.
What effect will this flag (is_ms_shipped = 1) have on my stored procedures?
Can I move these out of "System Stored Procedures" and into "Stored Procedures"?
Thanks!
Hello friends......How are you ? I want to ask you all that how can I do the following ?
I want to now that how many ways are there to do this ?
How can I call one or more stored procedures into perticular one Stored Proc ? in MS SQL Server 2000/05.
Hello
I'm start to work with SSIS.
We have a lot (many hundreds) of old (SQL Server2000) procedures on SQL 2005.
Most of the Stored Procedures ends with the following commands:
SET @SQLSTRING = 'SELECT * INTO ' + @OutputTableName + ' FROM #RESULTTABLE'
EXEC @RETVAL = sp_executeSQL @SQLSTRING
How can I use SSIS to move the complete #RESULTTABLE to Excel or to a Flat File? (e.g. as a *.csv -File)
I found a way but I think i'ts only a workaround:
1. Write the #Resulttable to DB (changed Prozedure)
2. create data flow task (ole DB Source - Data Conversion - Excel Destination)
Does anyone know a better way to transfer the #RESULTTABLE to Excel or Flat file?
Thanks for an early Answer

I am building a dashboard features that allows user to select reports from a dropdownlist. It is pulling from a table called Reports (cols: ReportID, Description, sqlView) In this Report table the report is associated to a view that queries the report.
And the user's selections are stored in table called UserReport (cols: userID, ReportID, createDt) .
I need to get a Dataset to contain datables of all reports selected. (for example a user select 3 reports, the dataset should contain 3 datables that represent the report).
I want to accomplish this by create a store procedure that queries the Reports table and then dynamically executes the views that related to the user selected reports. Can anyone give me an example on how to create the storeprocedure?

I want to turn this SQL into a stored proc; there are currently about 8 parameters that I want to pass into it. The field value for each will be either NULL or a positive integer, and the paramater will be passed in as an integer.
If the passed parameter value is a positive integer then it should return all records where the corresponding field value matches that integer. If the passed parameter is 0, it should return all rows regardless of whether the field value is an integer or NULL.
And I can't for the life of me figure out how to do it. Do I need an IF statement in there or something?

I am working on a C# stored procedure for SQL 2005, and i've uncovered a couple questions.
First a description of the procedure:
I have a series of equations taking place to calculate a score based on activities in which the user participated in, that will give them an over all grade or rating. The calculations currently take place in the database, and I am moving this from T-SQL to C# CRL.
1. In order to connect the stored procedure to the database I use a SqlConnection and a SqlCommand to execute either dynamic sql or a stored procedure to return data to a data reader. Is there an easier way to connect to the database? In SSMS if i open up the query it knows what database i am connected to. Do I have to make a sql connection in C# stored Procedures?
2. I have multiple functions within the main C# Stored Procedure that I'm working on. This ends up requiring Multiple Active Recordsets. I must set this withing the connection string. Seeing as I'm using a named instance of SQL 2005, I now must put the userid, password, and server name into the code. Is there a more secure way to connect to SQL Server in a C# Stored procedure that allows MARS?
3. I encryped the connection string, and put it into the assembly, I wrote a decryption class, and in the procedure itself everytime I need to refrence the connection string, I call it, decrypt it, and pass it along. But my code to decrypt the connection string is in the compiled DLL, if the server was ever compromised the encrypted connection string and the key to decrypt it are sitting in the DLL. Is there a config file that I can use for C# Stored Procedures?
4. If I have to keep the connection string in the file, then I need to change that per environment. Example I have 3 test environments before production. So I would need to change the connection string for each file. That may be fine for one procedure, but what if I have 20, that will quickly get of hand?
5. Along the security lines, can the assembly for a C# Stored Procedure be called from outside the assembly? From a command prompt, or by a maliceous program? Or could it be called directly by a .NET application instead of going through a T-SQL Stored Procedure that is using
WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [PROJECTNAME].[CLASSNAME].[METHODNAME]

Hi,
Do you know how to write stored procedures inside another stored procedure in MS SQL.
Create procedure spMyProc inputData varchar(50)
AS
----- some logical
procedure spMyProc inputInsideData varchar(10)
AS
--- some logical
--- go
-------
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

View 2 Replies View RelatedWe have a sort of complex user structure in the sense that depending on the type of user the data resides in different tables.

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?
