Multiply Numbers In A Column
Mar 21, 2002
Hi
I'm trying to find a decent way of multiplying a set of numbers in a column without using a cursor in T-SQL.
There is no 'Product' aggregate function that I'm aware of in SQL 7 or 2000. The workaround I'm currently using is this :
SELECT EXP(SUM(LOG(ColumnName))) FROM tblName
This works fine, except when negative numbers are introduced. The LOG function does not allow negative numbers and therefore returns a domain error and the negative number is eliminated from the aggregate.
I could use a cursor to do the multiplication, however, this is proving too slow for the bulk calculations involved.
If anyone has any ideas or suggestions, then that would be much appreciated.
thanks....Tom

I have a report with a column which contains either a string such as "N/A" or a number such as 12. A user exports the report to Excel. In Excel the numbers are formatted as text.
I already tried to set the value as CDbl which returns error for the cells containing a string.
The requirement is to export the column to Excel with the numbers formatted as numbers and the strings such as "N/A' in the same column as string.
Any suggestions?

SELECT EmployeeId, PiecemealType,SUM(PiecemealQty) /100 AS TotalTrays, ActivityId
FROM SR.dbo.PayTrays
WHERE WorkDate > '2012-01-01'
AND WorkDate < '2012-12-31'
GROUP BY EmployeeId, PiecemealType, ActivityId
ORDER BY EmployeeId, PiecemealType
PiecemealType is the type of tray
1= 15 Items per tray
2= 12 Items per tray
3= 8 Items per tray
4= 6 Items per tray
I'm trying to work out a bonus for 1 cent per item worked. The divide by 100 moves the total from cent to dollar and the SUM is adding all weekly values together.I just need to work out how to multiply the the SUM value for trays by the 4 different PiecemealType values. If it was static i could just add *15 to my SUM.

HI all;
I have a simple question to ask; I need to create a column with the data from my DOB column (which has the smalldatetime type attached to it). I know how to do that but I am not too sure how to convert the data from that column int normal character for example when I copy it into my newly created column and change the type to varchar I get this jan 16 1979 from this date 1979/01/16. But I actually want the data to look like this 19790116, so in effect I just want to take out the slashes.
Any help would be highly appreciated, thanks all.

Hello,
I have an ID column which is an Identity column, and it counts from 1 upwards.
If I have 10 records, I have ID's number 1 to 10.
If I then add another record, it will give the ID number 11.
Imagine I then delete ID number 9
Is it possible to get the next record I create to take number 9 instead of 12 ?

After moving our database between servers, one table had a hiccup in it's
identity column. The number jumped from 761 to 1886863475 on the next
insert. This is a production server and I didn't catch it until yesterday.
So I have several days worth of numbers in a central table. I can't clean
them out, but I wondered if I could do the following:
DBCC CHECKIDENT ('table_name', RESEED, 800)
I tested it on our development server and it doesn't seem to cause any
problems. I know that when we get to 1.8 billion on the identity column
again we'll get an error, but I'm willing to risk it.
A few questions. 1) Am I insane for trying this? 2) Has anyone else ran into
a similar problem and what did you do to fix it? 3) If I do this, is there
anything in particular to watch out for? 4) What caused the jump in the
first place?
My other option is to change the datatype from int to decimal(19) or
something along those lines. This will upset our programmers and I'll have
to change all my foreign keys (not a big deal, just a pain).
Any input at all here would be appreciated.
Thanks,
Grant

I'm trying to create a column of numbers that increment by one.
I'm not able to use a #temptable in the application I'm using so I cannot use IDENTITY(int,1,1).
I want to add an Id column to this query:
Select distinct sd.name,ic.TABLE_SCHEMA,ic.TABLE_NAME from sys.databases sd
cross join INFORMATION_SCHEMA.COLUMNS ic
where sd.name = 'ODS1stage'
order by TABLE_SCHEMA,TABLE_NAME
How can I accomplish this without creating a temp table? I would just alter the table and insert the numbers but there are 2000 rows.

Hello,
One more question about this Custom Calendar table I'm creating. I have a column called "IsWorkdays" which indicates if the day represented by a row is a workday or not. For our purposes, I also need to create a row that accumulates those numbers by month. So, if it is the 3rd workday of the month, this column would have a 3. This is beyond my current T-SQL ability. Does anyone know how to do this?
Thanks a lot,

I'm grappling with this issue which I thought was basic VB programming; I'm trying to insert a random number (between 100 and 999) into a SQL table column (=Status_ID). This is input as part of a user submitting helpdesk requests via a APS.Net Web Form. The 'Status_ID' field is obviously not visible to the user but will help reference this Helpdesk request on the database.Here is the code:Protected Sub submitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitButton.Click If Page.IsValid Then ' Define data objects Dim conn As SqlConnection Dim comm As SqlCommand ' Read the connection string from web.config Dim connectionString As String = _ ConfigurationManager.ConnectionStrings("ITNet_Students").ConnectionString ' Initialize connection conn = New SqlConnection(connectionString) ' Create command comm = New SqlCommand( _ "INSERT INTO HelpDesk (First_Name, Last_Name, StudentID, PersonalEmail," & _ "CategoryID, SubjectID, Description, StatusID) " & _ "VALUES (@First_Name, @Last_Name, @StudentID, @PersonalEmail, " & _ "@CategoryID, @SubjectID, @Description, @StatusID)", conn) ' Use randomize Randomize() Dim randomvalue As Integer ' Generate random value between 999 and 100. randomvalue = Int((900 * Rnd()) + 100) ' Add command parameters comm.Parameters.Add("@First_Name", System.Data.SqlDbType.NVarChar, 50) comm.Parameters("@First_Name").Value = fnameTextBox.Text . . . comm.Parameters.Add("@StatusID", System.Data.SqlDbType.Int) comm.Parameters("@StatusID").Value = randomvalue 'Enclose database code in Try-Catch-Finally Try ' Open connection conn.Open() ' Execute the command comm.ExecuteNonQuery() ' Reload page if the query executed successfully Response.Redirect("HelpDesk.aspx") Catch ' Display error message dbErrorMessage.Text = _ "Error submitting the help desk request! Please try again later, and/or change the entered data!" Finally 'close connection conn.Close() End Try End If End Sub----------------------------------------------------------------------------------------------------------------------I keep getting the error message under 'Catch' and the page 'HelpDesk.aspx' is not reloading; the 'comm.ExecuteNonQuery()' is not executing.Can anyone spot any inconsistencies in the declaration of the 'randomvalue' variable?P.S: this code works fine if you replace 'randomvalue' with any integer in 'comm.Parameters("@StatusID").Value = randomvalue'

Hi, I need to search a column in my database (varchar:50) that contains a comma delimited string of numbers (i.e. 1, 2, 3, 4, 5, 10). Currently, I am doing the following SQL query:
SELECT * FROM people WHERE clubs_belongs_to LIKE '%1%'
Where 1 is the number I'm searching for. The problem with the query above is that it returns records that contain 1, 10, 11, 12, 13, etc. in the clubs_belongs_to field. I want the query to only return those people who belong to club number 1, not 10, 11, 12, etc. Please help. Thanks in advance. I have tried using IN instead of LIKE, but that didn't seem to get the results I wanted either.

Hi,
Can anyone tell me offhand the simplest/most elegant way of updating an integer column to a sequential column of numbers with a query?
e.g given
intval | Description| Cost
0 | Descvalue0| 4.32
2 | Descvalue2| 4.33
3 | Descvalue3| 4.34
8 | Descvalue8| 4.35
change it to:
intval | Description| Cost
0 | Descvalue0| 4.32
1 | Descvalue2| 4.33
2 | Descvalue3| 4.34
3 | Descvalue8| 4.35
I think it might need a stored proc..
Many Thanks
greg

If Exists ( Select c.name from sys.columns c where object_id = object_id('HH835HP') and C.name = 'ID_1' )
Begin
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;

Obviously... The stuff inside the IF is wrong syntax...I mean
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;

Hi,
I have an excel export with numeric values. When the SSIS package writes into the excel it treats all data types as strings and attaches an apostrophe in the beginning. I tried formatting the excel sheet with the number data type and saving it . It doesnt work.
Other strange thing is that when I go into the advanced editor for the excel destination and look into the properties of the external columns all of them have the data type as Unicode String[DT_WSTR] irrespective of what the data type is from the input.The UI allows me to change it to numeric for numeric columns without any error but the value is not saved at all which is very frustrating. I also tried changing it in the xml file of the package, it some how seems to overwrite it after validation. It would be really nice if it threw an error saying that it cannot be changed.
Anyways there seems to be no way of changing the destination data type if it s an existing file and if I create a new excel sheet there is no way of formatting data. Is there any way out?
Thanks

The following works just fine. The table tmpMHPCLMDET does have a column ADMTDT ( varchar(8) ).
While I am adding the sequence of numbers I like it to be sorted based on ADMTDT column.
What that means is the row with the earliest ( smallest ) ADMTDT will get 1 and the next 2 and so on.
Declare @ID int
If Exists ( Select c.name from sys.columns c where object_id = object_id('tmpMHPCLMDET') and C.name = 'ServiceLineID' )
Begin
--Adding a sequence of numbers to the ServiceLineID column.
SET @id = 0
UPDATE tmpMHPCLMDET
SET @id = ServiceLineID = @id + 1;

I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.
Thanks for any help
