I have a problem while trying to update the content of my page to the database by the means of a stored procedure string OcompConnection = ConfigurationManager.ConnectionStrings["GenUserCode"].ConnectionString; System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection(OcompConnection); System.Data.SqlClient.SqlCommand ocmd = new System.Data.SqlClient.SqlCommand("Dealer_Insert", conn);ocmd.CommandType = CommandType.StoredProcedure; ocmd.Parameters.Add(new SqlParameter("@UserCode"), SqlDbType.NVarChar); ocmd.Parameters["@UserCode"] = TxtUserCode;
and also there is another error message saying that argument1: can not comvert from system.data.sqlclient.sqlparameter to string. What am i Missing??? Eventually there is the try{open} and finally{close}
I have problem with LINQ. I have created SQL Server 2005 database Database.mdf in App_Data folder with two tables - Pages and PagesGroups. Table Pages consist of fields PageID, AspxForm, DescriptionEN, DescriptionPL, PagesGroupID, NavNameEN, NavNamePL, PageActive, NavToolTipEN, NavToolTipPL and table PagesGroups consist of PagesGroupID, NavGroupNameEN, NavGroupNamePL, NavGroupToolTipEN, NavGroupToolTipPL, GroupDescriptionPL, GroupDescriptionEN, GroupActive. I added example rows. I created DataClasses.dbml, where Pages is child of PagesGroups, and DataClasses.designer.cs, which cause error "No overload for method 'DataContext' takes '0' arguments", in App_Code folder. I started writing LINQ commands in master page (DataClassesDataContext db = new DataClassesDataContext(); var pages = from p in db.Pages select new { Description = p.PagesGroup.GroupDescriptionPL };). What should I write in DataClasses.designer.cs that errors does not occur? What is wrong in my DataClasses.designer.cs? I wrote source of DataClasses.designer.cs, MasterPage.master and error message below. App_Code/DataClasses.designer.cs:

Hello, I am designing a small databse example. The database only contains one table 'Employee'. Only five fields: EmployeeID(primary key), firstName,lastName,phoneNumber,Salary. Salary is an integer. Now I drag some buttons to the form. One button is to find employee by ID, find employee by last name and find all employees inside a certain salary range. My Table Adapter--Change the Update and Delete command to only need 1 parameter(primary key). But I get three compiling errors.

Help I have not got much more hair to loose Thanks Steve
I'm running an ISP database in SQL 6.5 which has a table 'calls'. When thenew month starts I create a new table with the same fields and move the dataof previous month into that table and delete it from calls. So 'calls' holdsthe data of only the current month. for example at the start of november2003 I ran the queriesCreate Table Oct2003Calls {................................}/* Now insert data of october into new table */INSERT Oct2003CallsSELECT *FROM callsWHERE calldate < '11/1/03'/* Finaly delete october data from calls table */DELETE FROM callsWHERE calldate < '11/1/03'The problem is that while the insert query takes about 2 minutes to executethe delete queries takes over 10 minutes to affect the same no. of rows. Whyis that?This causes problems because user authentication stops when this query isrunning which means users cant connect to the internet.
It seems inserting records takes a relatively long time. My guess is it needs time to allocate disk space for the extra space needed. Assuming this is true, are there any DB settings that allow auto space allocation in bigger chunk? I am looking for something like "DB growth factor" or " Table growth factor"
Could some body in microsoft database team explain this behavior? Problem is predominant when cardinality of a column is very high and a where clause is specified on that column. Both use the same index.
I have a row that is being used log track plays on our website.
Here's the table:
CREATE TABLE [dbo].[Music_BandTrackPlays]( [ListenDate] [datetime] NOT NULL DEFAULT (getdate()), [TrackId] [int] NOT NULL, [IPAddress] [varchar](20) ) ON [PRIMARY]
There's a CLUSTERED INDEX on ListenDate ASC and a NON CLUSTERED INDEX on the TrackId.
I have a TRIGGER on the Music_BandTrackPlays table that looks like the following:
CREATE TRIGGER [trig_Increment_Music_BandTrackPlays_PlayCount] ON [dbo].[Music_BandTrackPlays] AFTER INSERT AS UPDATE Music_BandTracks SET Music_BandTracks.PlayCount = Music_BandTracks.PlayCount + TP.PlayCount FROM (SELECT TrackId, COUNT(*) AS PlayCount FROM inserted GROUP BY TrackId) AS TP WHERE Music_BandTracks.TrackId = TP.TrackId
When a simple INSERT statement is done on the Music_BandTrackPlays table, it can take quite a long time. When I remove the TRIGGER the INSERTs are immediate. The Execution plan for the TRIGGER shows that a 'Inserted Scan' is taking up most of the resources.
How exactly is the pseudo 'inserted' table formed?
For now, I think the easiest thing to do is update my logging page so it performs 2 queries. One to UPDATE the Music_BandTracks table and increment the counter, and perform the INSERT into the Music_BandTrackPlays table seperately.
I'm ok with that solution but I would really like to understand why the TRIGGER is taking so long. The 'inserted' pseudo table will be 1 row 99% of the time. Does SQL Server perform a table scan on all 20 million rows in order to determine what's new and put it in the inserted pseudo table?
I have spent the afternoon researching this, and to no avail so here's my question. I have a user input form with upwards of 60 fields that are to be filled in by the user (intranet environment). I want to post those values as a new record in an SQL database. I have setup an SQLDataAdapter tied to a parameterized stored procedure on the SQL server. I can successfully post data from the controls on the form when I set the parameter type to Control based. Here's the problem, though. I need to do some pre-processing on most of the values in the controls on the form. I have setup VB code (that executes when the user clicks the "Submit" button), that pulls in each control value, performs any necessary processing, and sets a variable to the value I actually want stored in the DB. How can I assign THAT value (from the variable) to the parameter for the stored procedure? Thanks, Dave
Hi, i am using vs2005 and microsoft SQL server mobile edition (.NET Framework Data Provider for SQL Server CE) to develop an application for wm5.0 pocket pc in language C# and now, i'm facing a problem on how to insert a new data into .sdf file with TableAdapter?example, i have a combo box and a button (known as AddButton) on my form1.cs, when i click the button, all the data from combo box will automatic insert into a database.

Hi, I was wondering if there is a method (other than BULK INSERT) to insert a (C++) application level array into the database, I have a variant type array populated with values that I want to insert, perhaps using ADO objects in quick time!
Hi, it is few days I posted here my question, but received no answer. Maybe the problem is just my problem, maybe I put my question some strange way. OK, I try to put it again, more simply. I have few textboxes, their values I need to transport to database. I set SqlDataSource, parameters... and used SqlDataSource.Insert() method. I got NULL values in the database's record. So I tried find problem by using Microsoft's sample code from address http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.sqldatasource.insert.aspx. After some changes I tried that code and everything went well, data were put into database. Next step was to separate code beside and structure of page to two separate files followed by new test. Good again, data were delivered to database. Next step: to use MasterPage, very simple, just with one ContentPlaceHolder. After this step the program stoped to deliver data to database and delivers only NULLs to new record. It is exactly the same problem which I have found in my application. The functionless code is here:http://forums.asp.net/thread/1437716.aspx I cannot find any answer this problem on forums worldwide. I cannot believe it is only my problem. I compared html code of two generated pages - with maserPage and without. There are differentions in code in ids' of input fields generated by NET.Framework:Without masterpage:<input name="NazevBox" type="text" id="NazevBox" /><span id="RequiredFieldValidator1" style='color:Red;visibility:hidden;'>Please enter a company name.</span><p><input name="CodeBox" type="text" id="CodeBox" /><span id="RequiredFieldValidator2" style='color:Red;visibility:hidden;'>Please enter a phone number.</span><p><input type="submit" name="Button1" value="Insert New Shipper" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "", true, "", "", false, false))" id="Button1" /> With masterpage:<input name="ctl00$Obsah$NazevBox" type="text" id="ctl00_Obsah_NazevBox" /><span id="ctl00_Obsah_RequiredFieldValidator1" style='color:Red;visibility:hidden;'>Please enter a company name.</span><p><input name="ctl00$Obsah$CodeBox" type="text" id="ctl00_Obsah_CodeBox" /><span id="ctl00_Obsah_RequiredFieldValidator2" style='color:Red;visibility:hidden;'>Please enter a phone number.</span><p><input type="submit" name="ctl00$Obsah$Button1" value="Insert New Shipper" onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$Obsah$Button1", "", true, "", "", false, false))" id="ctl00_Obsah_Button1" />In second case ids' of input fields have different names, but I hope it is inner business of NET.Framework.There must be something I haven't noticed, maybe NET's bug, maybe my own. Thanks for any suggestion.
I have a database which will be generated via script. However there are some tables with default data that need to exist on the database.I was wondering if there could be a program that could generate inserts statments for the data in a table.I know about the import / export program that comes with SQL but it doesnt have an interface that lets you copy the insert script and values into an SQL file (or does it?)
When I try to print a very simple report with rs2005 via the print button on the http://servername/report/pages/... website, it says "printing" but nothing happend. When I look at the server (win2003 SP1 + latest hotfixes) the www and sql2005 (SP1 CTP installed) services eat up 100% cpu for ever. I get no error messages neither in the rs log's nor in os application or system log. With profiler I found out, that there must be some loop. The following stored procedure exec DeletePersistedStreams @SessionID='24iumm55mp32l2ie2nezs0y0'is called about 650 times per second, which explain the load. The only way to stop this, is shut down and restart the www service. This behaviour can be found with all reports. The call, view and export of the same reports to pdf, xls, ... works without problems.

I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.
The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?
I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.
cn.Open() sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table scb = New SqlCeCommandBuilder(sda) sda.Update(dataset) cn.Close()
I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:
1. Start the PPC Program
2. Load DB into dataset
3. Create a ONE new record in dataset
4. Fill back to DB
When I take this four steps everytime, the filling time is almost 1s or even more!
Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)
However, when I give up the dataset and using the following code:
cn.Open() Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)
I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!
We need to select rows from the database that have been recently inserted/updated. We have a main primary table (COMMIT_TEST) and a second update table (COMMIT_TEST_UPDATE). The update table contains the primary key and a LAST_UPDATE field which is a datetime (to tell us when an update occurred). Triggers on the primary table are used to populate the update table.
If we insert or update the primary table in a transaction, we would expect that the datetime of the insert/update would be at the commit, however it seems that the insert/update statement is cached and getdate() is executed at the time of the cache instead of the commit. This causes problems as we select rows based on LAST_UPDATE and a commit may occur later but the earlier insert timestamp is saved to the database and we miss that update.
We would like to know if there is anyway to tell the SQL Server to not execute the function getdate() until the commit, or any other way to get the commit to create the correct timestamp.
We are using default isolation level. We have tried using getdate(), current_timestamp and even {fn Now()} with the same results. SQL Queries that reproduce the problem are provided below:
/* Different functions to get current timestamp all have been tested to produce the same results */ /* SELECT GETDATE() GO SELECT CURRENT_TIMESTAMP GO SELECT {fn Now()} GO */ /* Use these statements to delete the tables to allow recreate of the tables */ /* DROP TABLE COMMIT_TEST DROP TABLE COMMIT_TEST_UPDATE */ /* Create a primary table and an UPDATE table to store the date/time when the primary table is modified */ CREATE TABLE dbo.COMMIT_TEST (PKEY int PRIMARY KEY, timestamp) /* ROW_VERSION rowversion */ GO CREATE TABLE dbo.COMMIT_TEST_UPDATE (PKEY int PRIMARY KEY, LAST_UPDATE datetime, timestamp ) /* ROW_VERSION rowversion */ GO /* Use these statements to delete the triggers to allow reinsert */ /* drop trigger LOG_COMMIT_TEST_INSERT drop trigger LOG_COMMIT_TEST_UPDATE drop trigger LOG_COMMIT_TEST_DELETE */ /* Create insert, update and delete triggers */ create trigger LOG_COMMIT_TEST_INSERT on COMMIT_TEST for INSERT as begin declare @time datetime select @time = getdate()
insert into COMMIT_TEST_UPDATE (PKEY,LAST_UPDATE) select PKEY, getdate() from inserted end GO create trigger LOG_COMMIT_TEST_UPDATE on COMMIT_TEST for UPDATE as begin declare @time datetime select @time = getdate()
update COMMIT_TEST_UPDATE set LAST_UPDATE = getdate() from COMMIT_TEST_UPDATE, deleted, inserted where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY end GO /* In our application deletes should never occur so we dont log when they get modified we just delete them from the UPDATE table */ create trigger LOG_COMMIT_TEST_DELETE on COMMIT_TEST for DELETE as begin if ( select count(*) from deleted ) > 0 begin delete COMMIT_TEST_UPDATE from COMMIT_TEST_UPDATE, deleted where COMMIT_TEST_UPDATE.PKEY = deleted.PKEY end end GO /* Delete any previous inserted record to avoid errors when inserting */ DELETE COMMIT_TEST WHERE PKEY = 1 GO /* What is the current date/time */ SELECT GETDATE() GO BEGIN TRANSACTION GO /* Insert a record into the primary table */ INSERT COMMIT_TEST (PKEY) VALUES (1) GO /* Simulate additional processing within this transaction */ WAITFOR DELAY '00:00:10' GO /* We expect at this point that the date is written to the database (or at least we need some way for this to happen) */ COMMIT TRANSACTION GO /* get the current date to show us what date/time should have been committed to the database */ SELECT GETDATE() GO /* Select results from the table we see that the timestamp is 10 seconds older than the commit, in other words it was evaluated at */ /* the insert statement, even though the row could not be read with a SELECT as it was uncommitted */ SELECT * FROM COMMIT_TEST GO SELECT * FROM COMMIT_TEST_UPDATE
Any help would be appreciated, we understand we could make changes to the application/database to approximate what we need, but all the solutions have identified suffer from possible performance issues, or could still lead to missing deals (assuming the commit time is larger than some artifical time window).
So I know that each employee should have 2 Type 1's and 4 Type 2's. I hope that makes sense, I'm trying to change my data because ours is very proprietary.
I need to identify employees who do not have all their stages and list the stages they are missing. The final report should only have employees and the associated missing types and stages.
I do a count by employee to see how many types they have to identify the ones that don't have all the types and stages.
My count would look something like this:
EmployeeNumber Type Total 100, 1, 2 100, 2, 2 200, 1, 1 200 1, 2
So I know that employee 100 should have 2 more Type 2's and employee 200 should have 1 more Type 1 and 2 more Type 2's based on the required list.
The problem I'm having is taking that required list and joining to my list of employees with missing data and pulling from it the types and stages that are missing by employee. I thought I could get a list of the employees that are missing information and right join it to the required list where the missing records would be nulls. But, that doesn't work because some employees do have the required information and so I'm not getting any nulls returned.
