To create a strike file for a text file output, I piped the output of a query throught a mulitcast. One output is the actual flat file, the other output is the strike file. The next task for the strike output is an aggregate count and sum functions. If the original query returns no records, the count shows zero, but the sum shows NULL. Further down the process I have to pad out the values with zero's, but that NULL is causing problems. How do I convert the Null to either an empty string, or a value of zero?
Thanks
@Names is a query string passed in, I need to count the number of records as a result of the below query/
Dim test As String Dim sqlConnection3 As New SqlConnection("data Source=EQ-520-WEBSQLEXPRESS;Initial Catalog=CRDB.MDF;Integrated Security=True") Dim cmd As New SqlCommand

Good day, I just like to ask if anybody has experienced getting empty rows from SQL data adapter? I'm using SQL Server 2005. Problem is when the sql is run on Query Analyzer it retrieves a number of rows but when used in my application it returns 0 or empty rows. I thought the connection is not the problem since I got my columns right. Below is my code snippet. Thanks! const string COMMAND_TEXT = @"select distinct somefield as matchcode, count(somefield) " + "as recordcount from filteredaccount where StateCode = 0 group by somefield having count(somefield) > 1"; SqlDataAdapter adapter = new SqlDataAdapter(COMMAND_TEXT, connection); DataTable dt = new DataTable(sometablename); adapter.Fill(dt);
hi, im new to this site so i don't know if i'm posting in the correct forum. anyway, this is my code:---Dim dbMac As DBLibrary = Nothing dbMac = New DBLibrary(General.GetMACConnectionString)dbMac.OpenConnection("SPR_STAFFMAIN_GETEMPLOYEERECORDS")dbMac.CreateParameter("@USERENTITYID", GetUserEntityID(), Data.SqlDbType.Int)drpEmpNumbers.DataSource = dbMac.GetDataView("StaffMaintenance")gridStaffMaintenance.DataSource = dbMac.GetDataView("StaffMaintenance")gridStaffMaintenance.DataBind()---DBLibrary is a class that opens a connection to the SQL server. i'm getting an empty grid even though the stored procedure returns a row when i test it in the analyzer. is there to debug or test this code? thanks!
Hi, whenever the underlying query being called by EXEC in the followinghas an empty result set I get the following error -- Invalid Data for'Numeric' when EXEC returns empty row. However if I call the querywithout using REPLACE (which I'm forced to do, because openquery doesnot allow variables), I get just an empty result set.

In sql server 2000 - our QA pointed out that his testing for empty strings returned 200 + rows but that when he clicked in the field there were obviously a space there. This issue came up because of the script I created to replace and earlier one that queried on empty strings instead of datalength and the earlier script always reported that it had updated x number of rows regardless of how many times it was run on the same database.
QA query based on the earlier script: Select * from StringTable WHERE (LongString = '' OR LongString IS NULL)
My script: The fields are nvarchars in the newer database but older version of the database had varchars. I had created a script to replace empty strings as follows:
-- if LongString column is varchar - run varchar update else nvarchar update If exists (Select * from sysobjects o inner join syscolumns c on c.id = o.id where c.name = 'LongString' and o.name = 'StringTable' and c.xtype = 167) begin
-- update varchar LongString UPDATE StringTable SET LongString = char(32) -- Select * from StringTable WHERE ((DATALENGTH(LongString ) < 1) OR LongString IS NULL)
END Else Begin
-- update nvarchar LongString UPDATE StringTable SET LongString = char(32) -- Select * from StringTable WHERE ((DATALENGTH(LongString ) < 2) OR LongString IS NULL)
END
If exists (Select * from sysobjects o inner join syscolumns c on c.id = o.id where c.name = 'ShortString' and o.name = 'StringTable' and c.xtype = 167) begin
UPDATE StringTable SET ShortString= char(32) -- Select * from StringTable WHERE ((DATALENGTH(ShortString) < 1) OR ShortString IS NULL)
END Else Begin
-- update nvarchar ShortString UPDATE StringTable SET ShortString= char(32) -- Select * from StringTable WHERE ((DATALENGTH(ShortString) < 2) OR ShortString IS NULL)
END
My method for checking for datalength appears to work correctly why doesn't the QA script? I thought it might have to do with the nvarchar used in the table but I changed the column to a varchar and still has the same issue.
Hi all I am having some issues in selecting items from my database where the record is NOT NULL. I have the code below however although some fields do contain soem data in it, others are blank which I believe are empty spaces. How do I do a SELECT command which ignores empty spaces and NULLS?

SELECT CustomSearch FROM OfficesTable WHERE CustomSearch IS NOT NULL Thanks, Onam.
I have a column called QTY and I need to calculate the percentage for each row based on the total sum of the column. They are all decimals. I have an OLE DB source that is reading the table used an aggregate task using the QTY column with operation SUM and called the output SUM OF QTY. Then I have a Derived Column task that takes the QTY column / SUM OF QTY * 100 to create the percentage. My numbers are not coming out correctly and when I put a data viewer from the aggregate task, it shows the same number for both columns:
QTY SUM OF QTY
0.01833 0.01833 (this should be the sum of all the decimals in the QTY col)
We have a Data Flow Task. Inside this, we have a OLE DB Data Source which calls and executes a stored procedure. We use a Row Count Task to count the number of rows returned by the OLE DB Data Dource Task. Then, we use an aggregate function task to get the sum of all the rows of one particular column that is returned from the OLE DB Data Source. The issue here is that we want to assign the sum value returned by the Aggregate Function Task to a User Variable named User::Variable. We have tried to assign this by using @User::Variable and User::Variable, but neither of those return the expected value.
If there is any other method to do the same then let us know.
We have checked the that the row count is greater than zero. Any help would be very much appreciated.
On my office PC I have a strange problem with Data Flow Tasks. When I check-in a package into Source Control (Team Foundation) I usually have some empty Data Flow Tasks in the packages...even if I haven't changed that Flow Task.
This is really frustrating cause when running the package all goes well, but after a whil you notice that some tables are empty.
I have a field called CustomerName Varchar 100 and I wish to write a function that can do the following in a script component task
create a function called CleanString (ByVal CustomerName as String) As String
CleanString Returns the last word of a Customer name if the CustomerName field contains more than one word or if the CustomerName field does not contain Corp or Ltd
ie parse 'Mr John Tools' and the function returns 'Tools'
ie parse 'TechnicalBooks' and the function returns 'TechnicalBooks'
ie parse 'Microsoft Corp' return 'Microsoft Corp'
ie parse 'Digidesign Ltd' return 'Digidesign Ltd'
Any idea of a regular expression or existing piece of existing code I can have
In my current project i have a requirement to assign value of an aggregate transform to a variable. But i need to accomplish it without using a script task.
I am trying to create a SSIS package that will create a csv of a dataset for daily events in the database. However there will be days that there was no activity and thus an empty dataset. The package still runs fine but I want to stop the package if the dataset is empty.
FLOW:
DATA FLOW task: get daily data and put in CSV file
FTP TASK: upload the file to FTP server
MAIL/Copy file task: Move the file and then send a confirmation mail on task completion status.
Pretty simple and it all works great, I do have a few complexities in there. What I would like to add and I am at a loss is at the beginning, if the OLE DB Task resultset is empty then move to Mail Task otherwise process normally. I have tried conditional split, derived columns, the only thing I haven't tried in Script task and am not sure about that yet.
I am attempting to get this script provided by Microsoft to work to no avail. Specifically, when I set the variable FFNonDataRows to 1 (in order to accommodate for the header row), the variable is not being set to False as expected. I don't know enough about C# to understand why this script isn't working. How to get this script to work in this manner?
Hi, I have we have a client who gives their invoices in a flat file format, we import it into a SQL Server table. Nothing is normalized – everything is repeated in every record. The fields are: customerNumberInvoice_numberPO_numberQtyDescriptionLine_numberLine_totalFreightTaxInvoice_date So an if an order has 10 line items, the header information (invoice number, PO number, ivoice date) are repeated on each of the lines I am writing a query to show the following Order number, Invoice total, Date select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice_date from invoices group by invoice_no, Invoice, customerNumber This works great - for each invoice I get the invoice number, InvoiceTotal, and Date Then I was asked to add the PO Number – this is where I can’t get it right. When I added “PO_number� to the query, I got two lines for each invoice select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice, PO_number from invoices group by invoice_no, Invoice, Sold_To_Cust_No, PO_number Please help - I need to end up with: invoice_no, invoiceTotal, customerNumber, Invoice_date and PO_number (sequence does not matter) Thanks

First, It should get all items from @ItemHistory where WHERE DateSold >= '1/10/2007' AND DateSold < '1/11/2007' and then checks if corresponding items are found in @ItemStock, and then returns all the ItemID where sum(@ItemStock.Quantity) < sum(@ItemHistory.Quantity)

I have a database table that contains rows containing defect data. The two columns I'm interested in are device and severity. Device is the name of an item that contains the defect, and severity can be one of three values. I'd like to query the table so it shows the device, and the number of instances of each of the three values for that device. For example, the result table should look like this:

I have a table similar to the following: ID ¦ Name ID ¦ Period From ¦ Period To ¦ Percentage ¦ --------------------------------------------------------------------------- Important - Each person can have more than one entry. What I am trying to do is get the last percentage that each person obtained. The only way I have been able to do this is by the following: SELECT * FROM myTable LEFT OUTER JOIN ( SELECT NameID, MAX(PeriodTo) as PeriodTo FROM myTable GROUP BY NameID) t1 ON myTable.NameID = t1.NameID WHERE myTable.PeriodTo = t1.PeriodTo
I was wondering if there was another way of doing this, or whether this is an efficient method of doing this kind of query. Jagdip
I want to return a list that contains each employee's ID, the date of their last payrate adjustment, and their current payrate. Note that in the table below, employee 1002 was a bad boy in March of 2005, and his hourly rate was reduced to 14.00.
I am trying to use the following syntax and it is saying I can't use an aggregate function in a subquery. I can't use a GROUP BY in this case because if another field in the project table (such as status) is different, that project will show up twice.So in this case I am using this syntax to show the most recent quote within the project.
SELECT PROJECT.*, QUOTE.QuoteDate, QUOTE.QuoteCode FROM PROJECT LEFT JOIN QUOTE ON PROJECT.ProjectID = QUOTE.ProjectID WHERE QUOTE.QuoteDate=(SELECT Max(Q.QuoteDate) FROM QUOTE Q WHERE Q.ProjectID = PROJECT.ProjectID);
My goal here is to show the most recent quote within each project (there can be multiple revisions of a quote within each project). I want to show other fields such as the status of the quote, but if the status is different between quotes, the GROUP BY on that field will cause it to be listed more than once. All I want to show is the most recent quote for each project.
I'm working on a fairly complex query, and to avoid exploding my brainany further, I'm going to keep this simple with an example of what I'mtrying to do...Let's say you had a table of customers and a table of ordersAnd you had data that looked like this:CustomersCustID CustName-------------------------------1 Billy2 JohnOrdersCustID Amount PaidYN-------------------------------1 $2 12 $3 01 $4 11 $2 02 $5 0And you wanted a report that looked like this:Customer TotalPaid TotalUnpaid------------------------------------------Billy $6 $2John $0 $8How would you write a query to generate this report?
Quote: select distinct a.memberFirstName, a.memberLastName, c.ChapterName, d.divisionName, count(f.memberID) as numMembers FROM Members a INNER JOIN groupLeaders b ON a.memberID = b.memberID Inner JOIN Chapters c ON c.chapterID = b.chapterID LEFT JOIN divisions d ON d.divisionID = c.divisionID Inner Join groupsOfEight e ON e.groupLeaderID = b.groupLeaderID Inner Join groupOfEightMembers f ON f.groupOfEightID = e.groupOfEightID Group BY a.memberFirstName, a.memberLastName, c.chapterName, d.divisionName Order By divisionName, numMembers
This query returns me the names of all of my Group Leaders, their Chapter, Division, and the number of members they have selected to be in their group.
Now, instead of the number of members in each Group I would like to know the total number of Members in each division to appear in the count.
[NOTE: All chapters have a division, linked by a divisionID in the "Chapters" table -- I need to get a count of all the "ChapterMembers" [chaptermembers is a table also] that are in the Division.
Here is the query I started to build before I ran into serious trouble:
Quote: select a.divisionName, count('c.memberID') as numMembers From Divisions a Inner Join Chapters b On b.divisionID = a.divisionID Inner Join chapterMembers c ON c.chapterID = b.chapterID Left Join Members d ON d.memberID = c.memberID LEFT Join groupLeaders e On e.memberID = d.memberID Group By a.divisionName
This particular query returns only the DivisonName and the number of Members in the division as expected. However, when I try to select the information for the GroupLeader (first & last name) I am forced to add memberFirstName to the Group By statement which changes my Count...
Have I done an okay job of explaining the problem?
The goal here is to select all of the GroupLeaders first & last name, their chapterName, divisionName, and the total number of members in the division.
I have a table as below: COMPUTERNAME, COUNTER, REASON WXP-13Failed WXP-1113Failed WXP-38Failed WXP-910Failed WXP-117Success
What I would like to do is create a percentage of Success vs. the Failed for the same Computername. Problem is when I use Group by I cannot tell the COUNTER of the Success anymore. This is what I have been using:
SELECT COMPUTERNAME, SUM(COUNTER) AS COUNTERTOTAL FROM ReturnTable GROUP BY COMPUTERNAME
Thank you. The above query actually targets a result table from another query, but that should not matter.
