I am accessing data (YTD Hours for a selected employee) through the view "dbo_TIMS_HSTU_HoursHist_Insync" which is connected by ODBC to my application. The result "HSTUHoursPriorPeriods" is used to determine the rate of pay for a specific employee and is run literall each time a user enters a pay record at data entry.
Because the view itself returns about 1,000 records, before I select the specific record and associated Hours, it is a little slow from a data entry standpoint.
I understand I can achieve the same result through an SQL Procedure, but
for the life of me I don't know how.
For a particular application i retrieve records using stored procedure and bind the same to the data grid and display the same. The data are fetched from a table say A joined with couple of tables to staisfy the requirement. Now this table A has around 3700000 + records. The Select statement is as
Select column1, column 2, column 3...................... column 25 from table A
inner join hash table D on A.Column3 = D.Column3 and A.Column4 = D.Column4 and a.nColumn1 = @ParameterVariable Inner join table B on a.nColumn1 =b.nColumn1 inner join table C on A.column2 = C.column2
Indices defined on A are IDX1 : Column 3, Column 4 IDX2 : Column 1
Around 350 records per second are inserted into the table A during the peak operation time. During this time when executing the procedure, it takes around 4 mins to fetch just 25000 records.
I need to fine tune the procedure. Please suggest me on same.
Hi, I'm at my wit's end with this. I have a simple stored procedure: PROCEDURE [dbo].[PayWeb_getUserProfile] ( @user_id_str varchar(36), @f_name varchar(50) OUTPUT)AS BEGINDECLARE @user_id uniqueidentifier; SELECT @user_id = CONVERT(uniqueidentifier, @user_id_str); select @f_name=f_name FROM dbo.tbl_user_profile WHERE user_id = @user_id; ENDRETURN The proc runs perfectly from the Management Console. In my ASP.net form (C#), the following always results in: "Invalid attempt to read when no data is present." (I'll highlight the line where the error results): SqlConnection conn = new SqlConnection(<connection string data>);SqlDataReader reader; SqlCommand comm = new SqlCommand("dbo.PayWeb_getUserProfile", conn);comm.CommandType = System.Data.CommandType.StoredProcedure; SqlParameter f_name = new SqlParameter("@f_name", SqlDbType.VarChar, 50); f_name.Direction = ParameterDirection.Output;comm.Parameters.Add(f_name); comm.Parameters.Add("@user_id_str", SqlDbType.VarChar, 36).Value = Membership.GetUser().ProviderUserKey.ToString().ToUpper();reader = comm.ExecuteReader();Response.Write("Num: " + reader["@f_name"].ToString()); // ERROR: Invalid attempt to read when no data is present. reader.Close();conn.Close(); The data is there. When I put a watch on 'Reader', I see the correct first_name data there. Your help is appreciated.
Hi i have the following stored procedure which should retrieve data, the problem is that when the user enters a name into the textbox and chooses an option from the dropdownlist it brings back duplicate data and data which should be appearing because the user has entered the exact name they are looking for into the textbox. For instance Pmillio Jones Pmillio Jones Pmillio Jones Robert Walsh Here is my stored procedure; ALTER PROCEDURE [dbo].[stream_UserFind] -- Add the parameters for the stored procedure here @userName varchar(100), @subCategoryID INT,@regionID INT AS SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName, Users.userName ,UserSubCategories.userIDFROM Users INNER JOIN UserSubCategoriesON Users.userID= UserSubCategories.userIDINNER JOIN SubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHEREuserName LIKE COALESCE(@userName, userName) OR SubCategories.subCategoryID = COALESCE(@subCategoryID,SubCategories.subCategoryID);

I have two temporary tables, both contain field 'BranchID'.
First table @TEMPNET returns 10 different BranchIDs, but the second table @TEMPCREDIT returns only 7 of those IDs, so when I run select from both tables 'WHERE N.BranchID = C.BranchID2' the result is blank. If I limit both tables to the IDs that are the same in both sets, it works.
How can I get ALL the results from table1 AND the results from table2 which match table1?
DECLARE @TEMPNET TABLE ( BranchID int , NetSales decimal(18,4) , Cost decimal(18,4) , SaleMonthNbr int , SaleMonth varchar(15))
Hello there! I've been sitting here thinking how to work through this problem but I am stuck. First off I have two tables I am working with.

VS 2005 SQL 2005 Reporting Services Firebird.Net Data Provider 2.0 Firebird Database 1.5
This is what I am trying to do:
In SQL Server 2005 Analysis project,
Create a Data Source Create a Data Source View And Create a Report Model
I have successfully created the data source. When I try to create a Data Source View, it lists all the tables in the Firebird database. In the last step, when VS tries to import the metadata to its storage (I think), the Firebird Client throws the following exception:

Few notes:
If I remove the checkbox of €śCreate logical relationships by matching columns€?, the wizard proceeds smoothly. But when I open the data source view, there are no tables there and if I try to add more tables, I receive the same error as above.
I am also trying to follow this up the Firebird Client project since the error was thrown by Firebird DLL. However, has somebody done this before and/or can provide me some direction/information as to what I might be doing wrong?
Currently i am defining a simple relationship between Customers->Orders->Order Details through the Database Diagrams feature in the SQL 2K. Using the Server Explorer, i can see the Database Diagrams, but when i try to "drop" the Database Diagrams into the page, it gives the error message.
I would like to know the procedures to retrieve the database relationships from Database Diagrams and manipulate them through ADO.NET
I prefer to "convert" already defined relationship using SQL Server Database Diagrams into XSD file or probably there is another method to "read" those relationship and manipulate them.
We are using a simple CLR sp where an SQL statement is executed inside the same. THe execution happens in a server of different context that is connected inside CLR sp. The result set is returned in tabular format using pipe. But, when we access the result as below
it give the following error. Any help is appreciated. It seems to be some error with distibuted transaction. We tried adding BEgin Distributed trnasaction, but still the error comes.

Im currently in the process of developing a new system in ASP.net. The system uses multiple tables from a SQL database. To link information from say the products table to the suppliers table a unique key from the suppliers table is stored in the products table to show which products each supplier has bought...simple so far.
From this I can then pull out any of the information relating to that product instead of just displaying the ID. Currently this is done by creating a stored procedure and then dragging the stored procedure onto the dataset layer to create the data adapter.
Im not 100% this is the best way to be doing this. Is it possible to simply just link the tables in the dataset layer to display a string from another table instead of an ID referencing number?!
any help on this would be much appreciated as I cant really continue untill I have sorted out the data structure problems.Thanks in advancedmowfo
I have a situation where I want to load some entities from one table lets say the table is customers and i would like to load all the customers with first name = dummy, not only this i would like to load all the orders and order details for these specific customers (these are two different separate tables) . I want all this within one stored procedure that return me three results for three different tables. Please tell me whether it is possible and how.
Hi. I have a stored procedure "sp1" which returns a value (with the sql statement Return @ReturnValue). Is it possible for my asp.net page to retrieve this return value, and to do it declaratively (meaning without writing code to connect to the database in the code behind). If it is possible to do it like this please tell me how, and if not please tell me how to do it with code. Thanks in advance .
Is there a way to retrieve the parameter list for a given stored procedure?
I am trying to create a program that will autogenerate a list of stored procedures and their parameters so that changes to the database can be accurately reflected in code.
We have a domain where all computers are on GMT(Greenwitch Mean Time). We have an access front end that timestamps certain fields according to the client time that the program is running on, but we will be moving our client workstations off of GMT time and keep our SQL Server on GMT time, and want to keep the timestamps GMT.
So, I wanted to know if it was possible to create a stored procedure that gets the Server's time and returns it to the Access frontend for entry into the timestamp fields?
Or, if anyone has a better idea of how to get the time from the server to use on the clients, I would greatly appreciate it!!!
Hi all,I have heard that we must insert into two tables simultaneously when there is a ONE-TO-ONE relationship. Can anyone tell me how insert into two tables at the same time, using SP? Thanks Tomy
Please excuse me if this question has been asked before; I couldn’t find it. Perhaps someone could point me to the solution. A few years ago I wrote an order-entry application in classic ASP that I am now re-writing in ASP.NET 2.0. I am having very good success however I can’t figure out how to retrieve data from a stored procedure. I am using the FormView & SqlDataSource controls with a stored procedure to insert items into an order. Every time an item is inserted into the order the stored procedure does all kinds of business logic to figure out if the order qualifies for pricing promotions, free shipping, etc. If something happens that the user needs to know about the stored procedure returns a message with this line (last line in the SP) SELECT @MessageCode AS MessageCode, @MessageText AS MessageText I need to retrieve both the @MessageCode and the @MessageText values in my application. In classic ASP I retrieved these values by executing the SP with a MyRecordset.Open() and accessing them as normal fields in the recordset. In ASP.NET I have specified the SP as the InsertCommand for the SqlDataSource control. I have supplied all the parameters required by my SP and told the SqlDataSource that the insert command is a “StoredProcedure�. Everything actuly works just fine. The items are added to the order and the business logic in the SP works fine. I just have no way of telling the user that something important has happened. Does anyone know how I can pickup these values so that I can show them to my users? Bassicly if @MessageCode <> 0 I want to show @MessageText on the screen.
I'm generating a list of parameters needed by stored procedures, and I'd like to know which ones have default values assigned to them. To retrieve the parameter information I use:
sp_sproc_columns @Procedure_Name='InsertUser''
However, the column that is supposed to give the default value, 'COLUMN_DEF' always returns as NULL, even when that column has a default value assigned to it. i.e. CREATE PROCEDURE InsertUser@UserID INT = 10,.....
And then if I do a sp_sproc_columns @Procedure_Name='InsertUser'', the COLUMN_DEF value for the @UserID column is still NULL.
Does anyone know what I'm doing wrong and how I can retrieve the default value?
Hello!I use a procedure to insert a new row into a table with an identitycolumn. The procedure has an output parameter which gives me theinserted identity value. This worked well for a long time. Now theidentity value is over 700.000 and I get errors whiles retrieving theinserted identitiy value. If I delete rows and reset the identityeverything works well again. So I think it is a data type problem.My Procedure:create procedure InsertProduct@NEWID int outputasbeginset nocount oninsert into PRODUCT(D_CREATED)values(getdate()+'')set nocount offselect @NEWID = @@IDENTITYendMy C# code:SqlCommand comm = new SqlCommand("InsertProduct", sqlCon);comm.CommandType = CommandType.StoredProcedure;comm.Parameters.Add(new SqlParameter("@NEWID",System.Data.SqlDbType.Int)).Direction =System.Data.ParameterDirection.Output;try{SqlDataReader sqlRead = comm.ExecuteReader();object o = comm.Parameters["@NEWID"].Value;//...}catch ( Exception ex ){throw ex;}The object o is alwaya System.DbNull. I also tried to use bigint.Any hints are welcomeCiaoSusanne
I am currently developing my first database driven application and I have stumbled over some quite simple issue. I'll describe my database design first: I have one table named images(id (identity), name, description) and one table named albums (id, name, description). Since I'd like to establish a n:n connection between these, I defined an additional table ImageInAlbum (idImage, idAlbum). The relation between these tables works as expected (primary keys, foreign keys appear to be ok).
Now I'd like to insert data via a stored procedure in sql server 2005 and I'm not sure how this procedure will look like. To add a simple image to a given album, I am trying to do the following: * Retrieve name, description from the UI * Insert a new row into images with this data * Get the ID from the newly created row * Insert a new row into "ImageInAlbum" with the ID just retrieved and a fixed Id from the current album.
I know how I would do the first two things, but I am not used to Stored Procedures syntax yet to know how to do the other things.
Any help is appreciated ... even if it means telling me that I am doing something terribly wrong
"I meant to delete just one assignment, doing which was giving me difficulty.
I deleted a whole category by accident which had most of my daily grades in it for a course with quite a few of them. I was negligent in backing them up, so I cannot restore them. I have an XLS file from the midterm, but am missing about 6 grades after that.
Is there any way to recover the grades I had in the deleted category. It has been a couple of days since I entered any new grades. HELP!"
My current backup strategy is to do a full backup 5 pm, differentials every 2 hours, logs every 30 min, all so they arenot simultaneous. Backing these all to same backup device via three different jobs.
Then the server is backed up to tape shortly after the 5 pm full backup.
Obviously, I can't restore from the backup for this situation because it would hurt other data.
But - is there a way I can take last night's backup from tape and restore it to a different database than our production database? (Such a database doesn't at this time exist. Would I detach, copy over the files, and then reattach on prod and attach on the devl side, and then restore from the backup device to the devl copy?)
I've never had to perform this kind of rescue and am wondering if my backup strategy is flawed since it isn't immediately evident how I can easily do this.
I needed a similar thing from our Oracle DBA yesterday, and he went to tape, copied out a table and put it on the Oracle database under a different owner, and I easily fixed the few records that I had botched.
That's exactly what I need to do now with MS SQL 2000.
I was hoping someone would be able to help me, I trying to go through several databases, 111 to be exact, and get the data out of a particular table which is present in all the databases on the same server.
I know how to get the names of the databases from the INFORMATION_SCHEMA, but how can use the name for it to cycle through all the databases and get data out of the one particular table.
Hi, I need some help. I have this query where i need to pull up students that have more than or equal to 3 absences in a row. Now I am getting all those students that are absent but not in a row. But i was wondering if there is a way to tell if a student was absent three days in a row . There is a date field that is being used to identify the day of the class and a status field that identifies if the student was absent or present. Please help someone.
Up to the moment I've got enough knowledge for read data stored into .LDF files by dbcc log and so on. It's very useful and interesting. Now, I wonder how to retrieve the same information but on MDF files.
At first, I want to make sure that is not possible by mean of traditional methods (dbcc or something like that) I suppose so but I'd like to hear opinions regarding that.
Thanks in advance for any idea, though or further information.
this is a simple problem but it's just driving me mad as it's not reading from my dB. basically, I've have reviews stored in my dB and want to display them in a textbox by clicking on a button called btnReviews. I think the problem might be that there is too much text stored per row of the table (as it is a review), but I have the datatype set as text in sql. here's the simple un-errorred code I have behind the button. any ideas where I went wrong. i've a feeling it's something small but it's just taken too long to figure out.protected void btnReviews_Click(object sender, EventArgs e) { String strConn = ConfigurationManager.ConnectionStrings["conLocalDatabase"].ConnectionString; SqlConnection dbConnection = new SqlConnection(strConn); SqlCommand dbCommand = new SqlCommand("Select [ReviewC] From [Review])", dbConnection); dbCommand.Parameters.AddWithValue("Review", txtReviewView.Text); try { dbConnection.Open(); dbCommand.ExecuteNonQuery(); } catch (SqlException ex) { Console.WriteLine(ex.ToString()); } finally { if (dbConnection != null) { dbConnection.Close(); } } }
