Updating By Subtracting?

Nov 5, 2007

Hi,I am currently updating a column in my database table with the value typed into a text box. But it is updating with the new value, rather than taking away the value typed in from the present value of the column. 1. How would i subtract the value typed in away from the current column value?2. I guess I need to check the column value is above 0 before updating, then rebind the control to show new values after the update has happened, incase two people are using it at once. How would this be achived? Thanks for any help!!Jon   P.S.My code is:private bool ExecuteUpdate(int quantity){  SqlConnection con = new SqlConnection();  con.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True";  con.Open();  SqlCommand command = new SqlCommand();  command.Connection = con;  TextBox TextBox1 = (TextBox)FormView1.FindControl("TextBox1");  Label labname = (Label)FormView1.FindControl("Label3");  Label labid = (Label)FormView1.FindControl("Label13");  command.CommandText = "UPDATE Items SET Quantityavailable = @qty WHERE productID=@productID";  command.Parameters.Add("@qty", TextBox1.Text);  command.Parameters.Add("@productID", labid.Text); command.ExecuteNonQuery();  con.Close();  return true;}    private bool ExecuteInsert(String quantity)    {        SqlConnection con = new SqlConnection();        con.ConnectionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True";        con.Open();        SqlCommand command = new SqlCommand();        command.Connection = con;        TextBox TextBox1 = (TextBox)FormView1.FindControl("TextBox1");        Label labname = (Label)FormView1.FindControl("Label3");        Label labid = (Label)FormView1.FindControl("Label13");        command.CommandText = "INSERT INTO Transactions (Usersname)VALUES (@User)"+          "INSERT INTO Transactions (Itemid)VALUES (@productID)"+          "INSERT INTO Transactions (itemname)VALUES (@Itemsname)"+          "INSERT INTO Transactions (Date)VALUES (+DateTime.Now.ToString() +)"+          "INSERT INTO Transactions (Qty)VALUES (@qty)"+        command.Parameters.Add("@User", System.Web.HttpContext.Current.User.Identity.Name);        command.Parameters.Add("@Itemsname", labname.Text);        command.Parameters.Add("@productID", labid.Text);        command.Parameters.Add("@qty", TextBox1.Text);        command.ExecuteNonQuery();        con.Close();        return true;    }protected void Button2_Click(object sender, EventArgs e){  TextBox TextBox1 = FormView1.FindControl("TextBox1") as TextBox;  ExecuteUpdate(Int32.Parse(TextBox1.Text) );}protected void Button2_Command(object sender, CommandEventArgs e)    {        if (e.CommandName == "Update")        {            SqlDataSource1.Insert();        }    }}

Adding Or Subtracting

Jul 28, 2004

I'm in trouble. I have a table with some fields, one of them is an amount of money.
One field indicates whether the amount is negetive or positive. This fields has only two possible values, 'N' and 'R'. 'N' means the amount is negative and 'R' means the amount is positive.

The problem I have is that I have to sum these amounts to give a total for each customer and report them as

customer1 total amount1
customer2 total amount2

I don't know how to make a query to bring these results. I know that sum would bring me the total amount for each customer but I don't know how to specify which fields are supposed to be negative so that it subtracts them instead of adding them.

By the way I'm not allowed to change the structure of the table.

Could you help me try to create this query?

SQl Running Totals And Subtracting

I have to point out that this is done in a grouped way where the CustormerID is the grouped clause. Now I have achieved this to a point where the calculations work only if the credit column is bigger than 0, but when the account starts with debit I get only sums of the column not the needed subtractions. What am I missing? Thanks in advance.

T-SQL (SS2K8) :: Subtracting Figures Within A Query

Aug 27, 2014

I have a table CombinedSales script below (CreateCombSalesTable.sql) which contains the details of a sale.

A row in the table has two flags online/offline
SalesAmount is the financial amount,
online = 1 (online sales)
online = 0 (combined sales off and online).

The table also contains the product and the client etc.,

What I am trying to do is subtract onlinesales from combinedsales within the query or outside I don't mind, to return the result as (below)

HERE is HOW I want the results to appear

skuid(No column name) onlineClientName
200437215183.350Asda
20043716816.651Asda

I query the table using:

select skuid,SUM(SalesAmount),online,ClientName from t_CombinedSalesDetails
where ClientName ='Asda'
and SkuId = 200437
group by Skuid,Online,ClientName
order by skuid

THIS is what I get below the online = 0 is the total sales of this product.

skuid(No column name) onlineClientName
200437232000.000Asda
20043716816.651Asda

How I could achieve the required results

/****** Object: Table [dbo].[t_CombinedSalesDetails] Script Date: 27/08/2014 13:23:27 ******/

GO
SET QUOTED_IDENTIFIER ON

How To Convert UTC Time (retrieved From SQL) To Local Time In Reporting Services Based On Time Zone

Aug 7, 2007



Hi all,

I have created a report in SSRS 2005 which is being viewed by users from different Time Zones.

I have a dataset which has a field of type datetime (UTC). Now I would like to display this Date according to the User Time Zone.

For example if the date is August 07, 2007 10:00 AM UTC,

then I would like to display it as August 07, 2007 03:30 PM IST if the user Time Zone is IST.


Similarly for other Time Zones it should display the time accordingly.

Is this possible in SSRS 2005?

Any pointers will be usefull...

Thanks in advance

SQL 2012 :: Accurate Sorting Data Each Time With Millions Of Records Without Time Field?

SET ANSI_NULLS ON

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.

It Takes A Long Time To Insert The First Record Each Time When The Program Start

Dec 15, 2006

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)

           cmd.CommandType = CommandType.Text
            cmd.ExecuteNonQuery()
            cn.Close()
            StartTime = Environment.TickCount

 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!!!

Problem With Getdate() In Transaction Takes The Insert Time Instead Of The Commit Time

Nov 12, 2007

Hi,

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).

Regards,

Mark

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?

SQL Server 2008 :: Displaying Transaction Time Punch Data In A Time Card Form?

Oct 7, 2015

I have a table called employee_punch_record that we use to store employee time clock punches.

The columns are:

employeeid,
punch_timestamp,
punch_type (In / Out),
closed (bit used as status for open or closed pay periods),
ident

Here are some examples of a record:

bkingery62015-10-06 16:59:04.000In0
bkingery72015-10-06 16:59:09.000Out0
bkingery82015-10-06 16:59:13.000In0
bkingery92015-10-06 18:22:44.000Out0
bkingery102015-10-06 18:22:46.000In0
bkingery112015-10-06 18:22:48.000Out0
bkingery122015-10-06 18:22:51.000In0
tfeller52015-10-05 17:00:05.000In0

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?

A Time Series Prediction Was Requested With A Start Time Further In The Past Than The Internal Models Of The Mining Model

Feb 19, 2008

Hi all,

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>

<Name>HISTORIC_MODEL_GAP</Name>

<Value xsi:type="xsd:int">1</Value>

</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?
