I'm an absolute beginner in asp/asp.net. You have been warned. I managed to run and compile asp.net using win xp home edition, via Visual Web builder 2005 express edition. I managed to use its tools to create a test database and table and put values in it. Now I wish to connect to this db using my aspx page. While fiddling around I finally able to drag the "table" icon on the database pane into my aspx page and it generate a code snippet below: <div> <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" EmptyDataText="There are no data records to display."> <Columns> <asp:BoundField DataField="US_ID" HeaderText="User id" SortExpression="US_ID" /> <asp:BoundField DataField="US_NAME" HeaderText="USer Name" SortExpression="US_NAME" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:nepConnectionString1 %>" ProviderName="<%$ ConnectionStrings:nepConnectionString1.ProviderName %>" SelectCommand="SELECT [US_ID], [US_NAME] FROM [USER]"> </asp:SqlDataSource> </div> When previewed in the browser, it seems to show the content of the db table. What I want to know is a sample coding on how to connect to the db the usual way (initialise the connection string, prepare and execute the query, fetch the content of resultset). Based on the code snippets above (it contains the info about the db name, table name and the column name I'm using), can anyone guide me by providing the lines of codes that retrieve the data? Basically the first thing I would like to do is fetching the data to be compared with user name and password submission after they click on login, among other basic stuff, which doesn't require bells and whistles like <gridviews> and other contraptions provided. And another thing, would the connection string or other parameters be any different from my computer if I were to upload my aspx page including the mssql db file into my webhosting to be tested live? Thanks for anyone out there willing to provide some hand-holding here!
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, What is the simplest way to crash a sql server? Somebody asked me that question, and I was unable to give the best answer. Please help me to find it. Thanks!! Joydeep
i need to retrieve column names in a rowset, let me explain a bit;
i can simply retrieve a column name by using IColumnsInfo::GetColumsInfo, but the problem is when i use "AS" keyword in the select statement such like;
SELECT identification AS id FROM test_table_a
i see alias name of that column instead the internal column name.
as you can guess the qestion is; how can i get both alias and internal name at the same time and of course what is the *usual* way to get it.
I am interested in what the simplest was to get a query result that will only ever have one result (ie One column, one row) into a variable. An ugly way is to use a cursor that simply fetches the first row but that seems to be a horrible way to do it and it has sometimes major drawbacks sometimes (mainly if I have to dynamically choose the table). Surely there is a better way?
What do you think? A simple example would be nice.
I am researching ideas for the best way to have users enter data into SQL.
I am familiar with VB and Access Forms and HTML coding but what I am looking for is a way to have a standalone app or website where users can enter information but I want the form to have branches that change depending on user input (such as selecting a meeting type then having specific questions open up related to it).
Any ideas on the best way to do this?
If a different forum would be better for this request please advise and I will move appropriately.
Instance of SQL2K5-SP1 on Server2003R2. Created two databases Test1 and Test2, create single 2-column table (tblTest)in Test1 with one row of data. Create SSIS package to transfer the table and its data to database Test2 using "Transfer Objects Task". Fails with error code 1073548784.
I have tested for security issues and don't beleive these to be the cause: I have monster privelidges and can successfully use SSIS packages to execute CREATE TABLE etc.
Have also tried most combinations of Task options (eg COPY ALL OBjects etc etc)
Have tried this on three different servers: same results.
This simple test is the result of distilling down problems I'm having with SSIS manipulating some 60G within some 300 tables, so I'd really like to use the power this task promises!
My head is getting a little sore from scratching - any advice gratefully received.
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me
USE [Testing] GO /****** Object: Table [dbo].[Testing] Script Date: 4/25/2014 11:08:18 AM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
[Code] ....
It seems to work fine with one million records.
Each primary key is unique, but the begindate is non-unique, and i guess even if i use datetime2 and add nanoseconds, from what i have read, there is a chance that i could have a duplicate datetime since the date is imported via XML from multiple sources.
Is there a way to keep track in real time on how long a stored procedure is running for? So what I want to do is fire off a trace in a stored procedure if that stored procedure is running for over like 5 minutes.
I am trying to load previous days data at 3 am via a SSIS job.
The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.
Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000
I hope to update a DateTime column value with a Time input parameter.  Poor attempt below but it looks like the @ApptTime param is coming in as 10:45:00.0000000 and I might have an existing @SendOnDate as: 2015-10-05 07:00:00.000...I hope to end up with 2015-10-05 10:45:00.000

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 don€™t 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).
I need to take a temporary table that has various times stored in a text field (4:30 pm, 11:00 am, 5:30 pm, etc.), convert it to miltary time then cast it as an integer with an update statement kind of like:
Update myTable set MovieTime = REPLACE(CONVERT(CHAR(5),GETDATE(),108), ':', '')
how this can be done while my temp table is in session?
We are using SQL Server 2008 as our database and use Access as a GUI. I am looking to create a form in Access where employees can access their time card and request changes from management. I want to use the format from the attached screen shot for the form. I pretty much know how to do it all, the only point of complication is trying to figure out the easiest way to get the transaction punch record data on employee_punch_record into a format where I can easily populate the form in the horizontal format you see in the screen shot.
I am not super strong in SQL, but figure I can do it using a formatting table of some sort. quick and easy way to move transaction records into a more horizontally oriented record?
I have a very simple time series model which processing works fine without any problem. However when I run the following query
SELECT
[TimeSeries].[PriceChange],
[TimeSeries].[Symbol],
PredictTimeSeries(PriceChange, -3, 2)
From
[TimeSeries]
WHERE
[TimeSeries].[Symbol] = 'x'
I get the following error:
TITLE: Microsoft SQL Server 2005 Analysis Services ------------------------------ Error (Data mining): A time series prediction was requested with a start time further in the past than the internal models of the mining model, TimeSeries, specified in the HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process.
The following is the excerpt of the minding model script related to the two parameters:
<AlgorithmParameters>
<AlgorithmParameter>
<Name>MISSING_VALUE_SUBSTITUTION</Name>
<Value xsi:type="xsdtring">Previous</Value>
</AlgorithmParameter>
<AlgorithmParameter>

</AlgorithmParameter>
<AlgorithmParameter>
<Name>HISTORIC_MODEL_COUNT</Name>
<Value xsi:type="xsd:int">10</Value>
</AlgorithmParameter>
</AlgorithmParameters>
These HISTORIC_MODEL_GAP (1) and HISTORIC_MODEL_COUNT (10) should accommodate PredictTimeSeries(PriceChange, -3, 2). Could anyone shed some light on this?
we have problems with our SQL Reporting Service 2012 (SSRS) server . We have setup Kerberos delegation between SSRS and the database server (SQL Server Always-on cluster) so users are authenticated down to the database. The issue occurs from time to time that SSRS loses the ability to delegate the user credentials to the database. At this point in time the Report Server logs contain rejected database connections because of ANONYMOUS logon. After restarting SSRS the problem is gone.
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!
Ok, so I have some horribly convuluted SQL that I would love to optomize. I'm not happy leaving it in it's current state, that's for sure!
I'm currently working on our test bed servers, so obviously my stats are out because of the "crap-ness" (yes, that's the technical term) of the hardware, but still, it should NEVER need to take this long!!
Basically, the issue arises in the nasty join to the career table (one employee can have multiple career lines). Just to make things complicated, employees can have any number of career records on any given date, these can even be input for future career events. The following SQL picks out the latest-current career date for each employee based on the career_date being <= GetDate() and the date of entry for this date being the greatest.
From the above we want to return 2007-01-01 | 2006-05-05 13:54:18.000

Oh judt to point out that "employee" is a view on the "Table 'people'." EDIT: I know it's pointing out the obvious, but I'm pulling out the managers "DN" from AD_Import based on the manager_number and employeeNumber matching.
I need a formula to calculate the time (let's say in minutes) between two dates/times. The problem is that I have to exclude the time between 06 PM and 06 AM and also exclude the time in the weekend (Saturday and Sunday). I will use this in a couple of reports made in Reporting Services. If anyone have an algoritm that could be modified for this and is willing to share this I would be very grateful. Many thanks! /Per Lissel
I have created several global temp tables to cache some intermediate results ... However, it seems that after a while those tables will be dropped by SQL Server 2005 automatically (I have not restarted the server and no drop table statement ever executed against those tables). Is this a feature by design? How to make those global temp tables persistence to next service restart?
I am reading about the RESTORE command to a point in time using logs, I would like to know the minimum point in time recovery for a backup image using T-SQL command before applying a log restore and what are the log ranges needed for the restore during restore.
I was working with Microsoft Time Series model (MTS) with some data, when in the mining model viewer, decision tree tab, I realized that the key time variable that I define, it was acting like a split variable.
So, I ask you, this is possible?, because, for me, this should not happen€¦.
After, I review the Data Mining Tutorial by Seth Paul, Jamie MacLennan, Zhaohui Tang and Scott Oveson, and I found, in the Forecasting part, that the key time variable (Time Index) it was acting like a split variable too, in for example, M200 pacific:Quantity and R250 Europe:Quantity.
So people, it€™s possible that a key time variable act like a split variable in a MTS model?
