I have used CLR stores procedures in SQL server for awhile now, but I'm still wondering what the best situations to use them are.MSDN provides some guidelines for use like heavy string manipulation (regex), or replacing T-SQL that declares lots of table variables and cursors.I'm curious to know what problems SO users are solving with CLR stored procs, and examples / benchmarks as well.
View 5 RepliesI'm working with system using Linq-2-SQL as its data layer, but which uses stored procedures to do the actual CRUD operations - the stored procs are configured against the CRUD methods for the data class in the model designer.These are all working just fine.Now we want to use partial classes to extend the functionality of our data classes to apply validation, and hold parsed versions of some of the database properties.
However when I create a partial class for one of the data classes, the datacontext stops using the methods configured against the dataclass and defaults to its own operations. This happens even if the partial is empty other than the just the class declaration.
I would guess that this might be because the method signature for the insert method stops tying up to what the datacontext is looking for, but I can't see any overrides available to help fix it.Is there a way around this so that I can use Partials and Stored Procs on the same data context?
I am developing an ASPX web page to return results from two SQL stored procs via VB. When I execute these two stored procs, they both return valid data. But for some reason, when I run this report it doesn't return any errors, however, it doesn't return any records/data either!
Also, I can't debug it for some reason, although I can set breakpoints! This is using VS 2008, but I think reason I can't debug is I believe this is a limited version that just works for SSRS and SSIS.
[Code]...
Could the problem be due to the fact that this web page uses the same SQL connection for both stored procs? The first proc should be returned initially, and the second proc after this screen. So I don't need both stored procs information simultaneously, so I would think I could reuse the same SQL connection.
OK, I found where the problem is located. If I just comment out the Level statement in the Where clause, it does return data. So only thing I changed was that one line in my SQL code and it works. This means missing data must be due to datatype incompatibility, no? What is the problem?
Trying to start a discussion on what approaches forum members take when faced with the issue of writing code that calls SQL queries upon a DB. Do you tend to always put SQL in stored procedures and call the proc (and does that include basic CRUD operations) or always the opposite? Or do you prefer a mix of some procs and some coded sql? If its the latter then how do you determine which queries go where?I imagine the scale of a project can dictate some of the possible answers. I've done both and sometimes I find that quick and dirty apps that have little chance of changing or are easy to modify do not need procs. On the other hand, I generally will choose the mixed option where anything other than CRUD (i.e. workflows) will be sent to a proc. I have a particular interest in hearing about your experiences with larger projects (i.e. 100+ tables in the DB) that employ a Domain Model approach to a layered solution (has distinct UI, business, and data access layers.) However I'm interested in responses to all sizes and shapes of projects.Opinions?
View 1 RepliesNeed to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

The store procedure which give me the information I need is:

When I try to add it to my report it gives an error, is it because of the temp table and how should I go about it?
I have a stored procedure to update a table, but needs a couple of values from another table.
the first two selects get the value from the table and then are used in the update statement.
The select statments:
Select @iStatusDropDownValueID = iDropDownValueID
From DropDownValue
Inner Join DropDownValueType On DropDownValue.iDropDownValueTypeID =
[Code].....
First, the values that are retrieved by the first two select statements are always the same. So they could be passed in by the code itself. I don't know that this will speed things up at all, just make the entire stored procedure better and easier to read.
Second, if the "Value Name" should change this store procedure will break (which is possible, but not often).
I am looking for any insight into the Best Practices for this situation.

I am currently building an ASPX webpage for internal use. Basically, there are two buttons on this page and I need each one to kick off a different stored procedure on our local SQLServer based on the needed task. these stored rocedures do quite a bit of work and take 3-5 minutes to finish running. In neither case do I need any kind of gridview or other output from these stored procedures, as they are simply crunching/cleaning data that will populate some tables that the user will then use to complete their task. There are also no inputs or parameters needed.
So i'm OK at ASPX and pretty good at SQL, but have no idea on the VB code behind page. This is what I have ben able to put together based on 3 days of googling. i think i am close but can't quite get across the line.

we are using vb.net in visual studio 2003. Now if ExecuteNonQuery is used then we do not get rows. If ExecuteReader is used then we get rows [ with forward-only access which is of no use to us] but we cannot get output parameters values returned by stored procedure?
I have a stored procedure that when I run it within my application it times out, but when I use Management Studio and pass in the same exact parameters, the stored procedure executes under a second. I had this exact same issue with the same stored procedure before, and all I did was recompile it, and it fixed the problem, but I do not want to keep having to recompile this stored procedure every few days or so. Has anyone else ran into this issue before?
Another note I would like to mention, is that I'm currently working on a test database, so I'm not inserting, deleting or updating any of the records that the Stored Procedure is using. So the database itself is not changing, but for some reason the Stored Procedure is showing degradation, and at the most we have 2 users in the database at a time.
Below is the code I use to call the Stored Procedure from my app.
cmd.CommandText = "sp__RECAP_SELECTION_GET_GRID_RECORDS_RECAP_TYPES"
cmd.Parameters.Add("@FK_KitchenID", SqlDbType.SmallInt).Value = cmbKitchenCustomer.KitchenID_SelectedPrimaryKey
[Code]....
As I mentioned, if I run the Stored Procedure within Mangement Studio, it runs with no problems. Also if I recompile the stored procedure, it runs fine within the app, but after a few days, the stored procedure starts to timeout again within the app and I need to recompile it again.
I am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).

I'm having problems trying to create a new stored procedure.I am using sql 2005 express. I also have sql server management studio express installed.I open up the studio express and goto the database that i want to use to create the stored procedure. When I right click i see a sub menu, but don't see a option that says create stored procedure ( or any option that has anything to do with stored procedures ).Am I right in saying that I need the full version of visual studio to be able to work with and create new stored procedures.I am also told that sql server comes with built in stored procedures. Am i right in assuming that I can call these without having visual studio installed. And if the answer is yes, then how do I find out the name of these procedures, the parameters they use and what each particular stored procedure does.
