If Page.IsValid Then
Dim usersDS As New System.Data.DataSet
usersDS = checklogin(userID.Text, password.Text)

Hi,
I am trying to remove rows of data when the value in a textbox in the row is 0.
My expression for a value of a textbox in my report layout is:
=Fields!salary_FTE.Value+Fields!Leave_FTE.Value
Could you please show me how I edit this expression so a row of data does not show when the value in this textbox is 0, or, should I create this filter in my query rather than in the report layout?
Thanks
This is a bit similar to the topic at

but with a bit of a twist...
I have
Batch Sample Value

0 1 A
1 0 A
1 1 B
2 0 B
2 1 B
...
I'm looking to get something that would provide a row comparison - something that looks like
Batch Different
0 FALSE
1 TRUE
2 FALSE

Any suggestions for a query that would do this? Thanks!

my requirement is to get the difference between adjacent rows.ie difference between 2nd and 3rd or 6th and 7th but not 6th and 8th.if difference between 2nd and 3rd is less than zero and 3rd modified date > 2nd modified date,then i should get count as 1 against 3rd row.
Hi,
I have a table that holds pay rate changes with a field for the rate start date and a field for the rate end date. When an employee gets given a new pay rate, the existing rate is given an end date and a new row is added with the rate start date being the day following the end date of the old pay rate.
I need to identify the staff who have had a rate change within the past month, therefore an end date on one row that is within one month of the current month, and a start date on another row that is one day after an end date on a separate row and within one month of the current month.
Is someone able to help me out please?
Thanks
Hi,
Im trying to output the number of rows in a table returned in a report, into a textbox for a total record count
How would I do this ?

I've been working with T-SQL in a MSSQL Server Management Studio (2005) for about a week now. I've been trying to convert some horribly written VB code from a MS Access DB over to SQL so it can be automated on a SQL backend.
Most of the learning process and coding has gone surprisingly well. The problem is with comparing some data to determine which one needs to be flagged.
Three tables to note in bold, with notable fields in italics below them:
EmployeeData
HRID (identity)
ResourceAllocation
ID (identity)
[Last Name] (linked to HRID)
Project
[Resource Start Date]
[Resource End Date]
[Percent Utilization]
tblHCvalues
RAID (linked to ResourceAllocation.ID)
a monthyear and quarteryear for every month and quarter from 2012-2014. IE january12, february12, 1q12, 2q13, etc...
And yes, there are probably a thousand ways to optimize that tblHCvalues, but I'll ask about that later. Just work with the structure I have
Here's how it works: Each employee's data and unique HRID is in the EmployeeData tableAn employee can be on one or multiple projects at any timeThose projects are stored per project in the ResourceAllocation table with a link to the Employee's HRID, and all the other information listed aboveEven though an employee might be on two projects, they can only count for headcount on one project.
We use rules that compare the percent of work being done on a project, and the start and end dates of the employee (resource) on that project to determine which project should be counted for Headcount. The code uses a cursor to go through each HRID, and then pull up all the ResourceAllocation records associated with it.Run the rules to determine which ResourceAllocation record counts toward headcountA stored procedure then runs that fills out the tblHCvalues in the way we want for the project we want
All of it works, except for the rules that compare the things, so that's what I want to focus on in this thread. How do I write these rules:
Here are the rules, and they should work for any number of multiple resource allocations for one employee:
Choose the ResourceAllocation with the greatest [Percent Utilization]If the top ResourceAllocations have equal [Percent Utilization], choose the ResourceAllocation with the earliest [Resource Start Date]If the [Percent Utilization] and the [Resource Start Date] are equal, choose the latest [Resource End Date]If all three fields are equal, choose the first ResourceAllocation (aka, screw it and pick one at random)
I'm sure I could use a bunch of IF statements to compare it all, but even that is complicated to think about. There has to be an easier way, right?
How do I only select rows with duplicate dates for each person (id)? (The actual table has approximately 13000 rows with approximately 3000 unique ids)
p_key id date pulse
--------------------------------------
1 32 5/25/2006 80
2 32 5/25/2006 85
3 32 4/26/2006 81
4 32 6/15/2006 82
5 15 1/20/2006 75
6 15 3/25/2006 80
7 15 3/25/2006 83
Result table I am looking for:
p_key id date pulse
------------------------------------
1 32 5/25/2006 80
2 32 5/25/2006 85
6 15 3/25/2006 80
7 15 3/25/2006 83

Hi,
I've a bunch of records that may contain data that I'm after. For example:
This is a fake title [electronic resource]. 1997.
I have a very small table (~10 rows) of things like '[electronic resource]'
Is there any way to see if my record contains any of the 'target' items in the other table?
I'm trying to come up with an elegant, simple way to compare twoconsecutive values from the same table.For instance:SELECT TOP 2 datavalues FROM myTable ORDER BY timestamp DESCThat gives me the two latest values. I want to test the rate ofchange of these values. If the top row is a 50% increase over the rowbelow it, I'll execute some special logic.What are my options? The only ways I can think of doing this arepretty ugly. Any help is very much appreciated. Thanks!B.

I am working on SQL server 2005 Reports.
I have one report, one dataset is assigned to it, and one table which displays it.
Now I come accros requirement that, the column value in the filter condition for the table is present in one textbox.
I can not use textbox i.e. reportItems in filter condition. Can someone suggest me how to use textbox value in filters?
I want to display parent/child records on report. I am not getting the proper solution.
The data is like this:
Sequence ItemCode IsParent
1 XYZ 0 'do not have child record
2 PQR 1 'have child records with sequence no 3
3 ASD 0
3 AFDGE 0
3 VDC 0
4 ASR 1 'have child records with sequence no 5
5 ASR 0
If IsParent = 1, that record has child records with sequence = parent sequenece + 1
I think u can understand the data I need to bind, and it is like:
XYZ
+ PQR
ASD
AFDGE
VDC
ASR
On + click we can do show/hide of child records.
I m not getting how to achive this in SQL server report. Can u give some hint?
Thanks in advance

Hello!
I'm using business objects to show the report Some fields have expression like

but when Address value == null then textbox will show #Error label.
Any ideas how to hide this #Error label, beacause if Customer does not have address I'd rather see empty value than #Error in report
Thanx

Hi all,
I've recently started using reporting services after about a 2 year break and have been refreshing my knowledge. I've got a very simple report linked into MS CRM, the report is designed to display cases that are overdue, displaying green colums for cases less that 2 hours old, orange for 2 - 4 hours and red for over 4 hours.
In the backgroundColor field for the details colums I have this code-
Code Snippet
=iif(Fields!Hours_Neglected.Value < 2, "Green", iif(Fields!Hours_Neglected.Value > 4, "Red", "Goldenrod"))
this works fine in the preview window in VS2005 but when I try to deploy I get this error:-
"Warning 1 [rsRuntimeErrorInExpression] The BackgroundColor expression for the textbox €˜ticketnumber€™ contains an error: Input string was not in a correct format. G:AppsVisual Studio 2005ProjectsCRM ReportsCRM ReportsNo Responce.rdl 0 0"
Can anyone shed any light on what this problem is as I'm struggling to find anything online......
Thanks in advance
Hi!
I use LINQ to SQL for showing reports, everything works fine but when I do something like
Fields!Order.Value.Customer.Address.StreetName it will show The addressStreet value
but if Customer or Address object value is null Textbox will output #ERROR message.
How can I get rid of this, is there any way to override the Textbox control?
Hi!
I dont know if i will explain this correctly, but my problem is with reporting service.
I'm supposed to Sum value in one textbox and than that sum use it in sum in other textbox.
Something like this:
Sum(Fields!Abc.Value/(Fields!dfg.Value+Sum(Fields!abc.Value)),"matrix1_RowGroup1")*100
I get error msg 'The Value expression for the textbox 'textbox49' contains an aggregate function (or RunningValue or RowNumber functions) in the argument to another aggregate function (or RunningValue). Aggregate functions cannot be nested inside other aggregate functions.'
Something like this wont work either Sum(Fields!abc.Value/ReportItems("textbox56").Value)*100
Error The Value expression for the textbox 'textbox55' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers.
So, pls help if you know how to reference textbox in other in body of report.
Thx.
Hi,
I have application in which i am performing synchronization between SQL Server 2000 and SQL Server 2005 CE.
I have one table "ItemMaster" in my database.There is no relationship with this table,it is standalone.I am updating its values from Windows Mobile Device.
I am performing below operations for that.
Step : 1 Pull To Mobile
Code BlockmoSqlCeRemoteDataAccess.Pull("ItemMaster", "SELECT * FROM ItemMaster", lsConnectString,RdaTrackOption.TrackingOn);
Step : 2 Using one device form i am updating table "ItemMaster" table's values.
Step : 3 Push From Mobile
Code BlockmoSqlCeRemoteDataAccess.Push("ItemMaster", msConnectString);
So i am getting an error on 3rd step.
While i am trying to push it says,
"The Push method returned one or more error rows. See the specified error table. [ Error table name = ]".
I have tried it in different ways but still i am getting this error.
Note : Synchronization is working fine.There is not issue with my IIS,SQL CE & SQL Server 2k.
Can any one help me?I am trying for that since last 3 days.

Hello All,
I created two database instances in the same MS SQL SERVER 2005 named hafeez and local. I created a linked server from hafeez database to local named HTOL
I created a dummy table in local database named samplocal.
Now i am able to list the records using the linked server, for this i used the following query.
SELECT * FROM OPENQUERY(HTOL,'SELECT nameandval FROM SAMPLOCAL');
Now the problem is, i am not able to insert the rows into the samplocal table using linkedserver. I am using the following query to insert the rows and getting the following errro.
INSERT INTO OPENQUERY(HTOL,'SELECT nameandval FROM SAMPLOCAL') VALUES('tertertetttwertw');
Msg 7356, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI" for linked server "HTOL" supplied inconsistent metadata for a column. The column "nameandval" (compile-time ordinal 1) of object "SELECT nameandval FROM SAMPLOCAL" was reported to have a "Incomplete schema-error logic." of 0 at compile time and 0 at run time.
Is the above query correct? or shall i miss anything?
Please guide me.
Thanks in Advance

Why does sp_helprotect throw an error if there are no special security permissions for a specified @username? Why not simply return a blank resultset? This makes the procedure a hassle to use when trying to capture results into a table as part of another stored procedure (use it for auditing).
[Edited]The same problem occurs when I execute xp_logininfo to get the list of members for a group that has no members. Instead of just passing back some sort of status, the procedure blows up and keeps me from scripting the procedure.
Am I just missing something?

I have a problem with my SSIS. I have a data flow with a file source in csv, but itself has 140 000 rows, so when I execute the date flow, I have a error who say that the data exceed the temp of I/O (sorry for the translate, but I have the message in french).
I test to pass the DefaultBufferMaxRow to 140000 but I have always the problem.
If we can help me, thank you.
I've got a Derived Columns component as part of a data flow. On this I've set the error output for my columns to Redirect Row in all cases. I've set a data watcher on the error output and then ran the package.
There are several rows which I'm expecting to fail - about 3 of them. These fail but there are also another 697 which seem to have no problem. So I fixed one of the problem columns in the source data and then re-ran the package. I only updated one row in the source so this row no longer appeared in the error output, but neither did several hundred of the other rows.
Is it possible that the error output has been tripped for that one row but for some reason it sends several hundred more rows? The ids on these additional rows follow on from the erroneous row, and when I fix that row the rows following it no longer appear in the error output.
Lately I noticed that I cannot return any rows using enterprise manager. The version I am using is MS-SQL 7.0 with SP 1 on NT. This will return an error:-
An unexpected error happened during this operatation.
[Query]-Query Designer encountered a query error.
Unspecified error.
I can return rows using another computer with enterprise manager installed.
Any help appreciated.

Hi,
I know we can redirect a error to say an OLE DB Destination or textfile. Is there something we can do so that I can know seeing the error table the reason for which the row failed.
The Error table will look just similar to the destination table, but for one col which should hold the reason say 'Truncate error' etc...
Is this possible???
Thanks,
All,
I'm getting a strange error in SSRS when there is no data returned from a OLEDB datasource.
Here are the steps to simulate the error
1. Create 2 shared datasources to the Adventure Database - one using ADO MD provider (Microsoft SQL Server Analysis Services (AdomdClient)) and another using OLEDB (OLEDB 9.0 for Analysis Services)
2. Create a new report and create a dataset with the ADO-MD provider and copy and paste the below query. (This query will not return any data)
SELECT NON EMPTY [Measures].[End of Day Rate] ON 0 ,NON EMPTY {[Date].[Date].&[10000]} ON 1 FROM [Adventure Works]
3. Run report. It will be blank as nothing is defined in the layout. But this shows that the query is executed in the dataset and is succesfull although the query does not return any data.
4. Create another report and create a dataset with the OLE-DB provider and copy paste the above query.
5. Run the report. It will come back with error in the lines of "Object reference not set to an instance of an object". The reporting services log file will show that the query execution has failed although this is not the case when analysed from profiler.
Any ideas on how to solve this? What I'm trying to acheive is to use the NoRows property of table to display a message when there is no data. But I'm not able to pass the above hurdle when no data is returned from the dataset.
Thanks in advance.
