Why I Cannot Easily Change The Value Of Parameter?
Aug 19, 2006
Hi all,
I read the Tang and Lennan's book 'SQL Server 2005 Data Mining'. It frequently says
about changing the value of the algorithm's parameter. I tried changing values for
MINIMUM_PROBABILITY in one occasion. However, the dialog box refuses to
change the value; for any of 'Value', 'Default', and 'Range'. Similar thing happens
when I tried to change the value.
What I can do is delete the parameter, then add it again. Even so, I can only supply
the value, not the default value and range (of values).
What happen? Again, is this because I'm using evaluation copy?
Hiya! I'm developing an app. using SQL Server 7 (as the back end) for a company supporting approx. 200 unrelated clients, all in different locations. There is no LAN or WAN connection between them, so we'd probably need to use TCP/IP. The problem is as follows: We have dynamic reports in our app. which are run based on data in two tables. Whenever we add a new report we'd like to send it to all of our clients i.e. update their tables to reflect the additional rows of new report info. How would this best be handled, by DTS or Replication or BCP? And how could it be done with either?
and BSmith's idea (no relation), I came up with this silly stored proc to compare any two tables or views. Supply the table names and the columns you wish to compare and have fun!
The key to the GROUP BY approach is that it handles NULLS quite well which JOINS have trouble with.
-- Table1, Table2 are the tables or views to compare. -- T1ColumnList is the list of columns to compare, from table1. -- Just list them comma-separated, like in a GROUP BY clause. -- If T2ColumnList is not specified, it is assumed to be the same -- as T1ColumnList. Otherwise, list the columns of Table2 in -- the same order as the columns in table1 that you wish to compare. -- -- The result is all records from either table that do NOT match -- the other table, along with which table the record is from.
declare @SQL varchar(8000);
IF @t2ColumnList = '' SET @T2ColumnList = @T1ColumnList
set @SQL = 'SELECT ''' + @table1 + ''' AS TableName, ' + @t1ColumnList + ' FROM ' + @Table1 + ' UNION ALL SELECT ''' + @table2 + ''' As TableName, ' + @t2ColumnList + ' FROM ' + @Table2
set @SQL = 'SELECT Max(TableName) as TableName, ' + @t1ColumnList + ' FROM (' + @SQL + ') A GROUP BY ' + @t1ColumnList + ' HAVING COUNT(*) = 1'
hi, I have a dropdownlist parameter like Today, 1 week ago, 2 weeks ago and I have 2 datetime parameters. What I want is when I select 1 week ago in the dropdownlist parameter I want other date parameters to be today-7 and today respectively. Is that possible?
I have this query that I would rather not turn into a stored proc.because the client really has no budget. I was hoping there would be away to add this statement inline to the following sql with some kind ofIF statement without writing it all out. The problem is either totalcost or conversions will have some zeros in the table.SUM([total cost]/[cost per conversion])Any help would be appreciated - Happy New YearSELECT [Search Term], SUM([total cost]/[cost per conversion]) as calcw,SUM([impressions]) AS impress, SUM([Total Cost]) AS totalcost,SUM([Total Clicks]) AS totalclicks, SUM(Conversions) AS totalconv,SUM([Cost Per Conversion]) AS costconv FROM csv where [start date][color=blue]>='01/01/04' and [end date] <='12/31/04' GROUP BY [Search Term] ORDER[/color]BY [Search Term] ASC
i suspect i know the answer to this already, but here goes anyway....i have a table that has field of varchar(2048), which once in a blue moon ineed to edit the data manually (until a bad character parser validates thedata before it's written ;-) )at the moment i'm doing this through enterprise manager (sql server 2000),opening the table then filtering using where clauses etc to see the recordsi'm interested in. i then edit the data direct in the results pane (purelybecause it's quicker than entering the UPDATE transact SQL). this is fineuntil i hit a record that has 1024 or more characters in the field. all ican do is delete all the data. if i try and paste the same data into thefield again, it'll truncate the record to the first 1024 chars (unconfirmed)despite the field being able to take double that.i've googled this and the result basically said "don't be lazy, do itthrough UPDATE transact SQL in the query analyser".anyone know if that's my only option or is there a patch / whatever to allowme to keep using entman as i lazily do at the mo?cheers!
Hello. I have a gridview that is connected to a sql datat srource witch gets a few columns to populate the GV with. I also have a drop down list where i enable the user to fill the gridview with the values that only match a specific category. What iv done is that i have a selected index changed event on my drop down list that does the following.string kategori = DropDownListKategori.SelectedValue.ToString(); Label1.Text = kategori; SqlDataSource1.SelectCommand = "SELECT [ARTNR], [ARTTYP], [AKTIVITET], [DATUM], [KUND], [PLATS], [KOMMENTAR] FROM [ARTIKEL] WHERE [ARTTYP] = @ARTTYP"; SqlDataSource1.SelectParameters.Add(@"ARTTYP", kategori); SqlDataSource1.DataBind(); Now when i launch the webpage and select a category (kategori) the gridview chanes and displays only the values that match that category but when i slect a new category Visual Studio throes me the following. The variable name '@ARTTYP' has already been declared. Variable names must be unique within a query batch or stored procedure. I thought that the parameter would get a new value but aparently when its set i cant declare a new value inside. What id like to know is how i can modify the above code so i can pass a new value to my select as soon as the drop down changes.

Am I correct in assuming that installing a SQL EE application on to a local runtime desktop would require a lot of experienced user intervention to install the SQL to each local cpu? Can a SQL app be installed automatically w/o a user intervening?
One of our Sales Reps is having issues with a report I've made and as far as I know he's the only one (Out of about 50) who has had this issue. He's running IE 7. What happens is he'll enter in the parameters and run the report and it works fine. But when he goes to change the dates he entered as parameters and then clicks "View Report" again to run the report again, the browser just redisplays the same results and doesn't even generate a new report. It appears as if the browser has cached his previously ran report and then just redisplays it instead of going back to the server and re-generating the report. Has anyone seen this before or have any ideas? I appreciate it.
I have located the Server where Reporting Services has been installed and I believe I have found the Report Server Database. Is there any way from the Report Server Tables that I can try and figure out where the Report Manager URL might be?
I have created an ASP.NET website with a ReportViewer on. The report renders fine, but when I change one of the parameters (manually), the report seems to invalidate itself and a blank while area is drawn. I would like the same behaviour as in the WinForms variant, where rhe rendered report remains the same until the 'View Report' button is pressed.
I have couple of paramters with operator 'range(inclusive)' in my report(Agains datacube), and I always get failure when I choose value with them. here's a example( 3 such parameters on my report).
...
From date To Date
...
From age To Age
...
From Salary To Salary
@salary is the last one.
when i choose a value for 'From Salary' or 'To Salary' from the dropdown list, it runs correctly. But if I choose value for 'from age' or 'To age' or 'From Date' or 'To Date', it fails due to
An error has occurred during report processing. (rsProcessingAborted)
Query execution failed for data set 'DimTimesheetTimesheetNumber'. (rsErrorExecutingCommand)
Range operator ( : ) operands have different levels; they must be the same.
BTW, all the default values for these parameters are 'all', since it allows only 'all' to select when I set up the parameters, and I tried to change the default value, but it caused errors about the parameter dependency.
I'm using report with a date parameter (user enters a date) and all transactions before that date are displayed. I don't know how to set parameter date format on the displayed report to dd/mm/yyyy.
If it's not a parameter I usually use sql " convert(varchar(10),datefield,103)" but don't know how to use this with parameter.
Hello, I cannot find out to create enum data type in SQL Server 2005 Express. Can I easily create the enum type just like the MySQL does.(please the MySQL example below)
CREATE TABLE myTable ( myid INT UNSIGNED NOT NULL, myclass ENUM('FIRST','SECOND','THIRD') DEFAULT 'FIRST' PRIMARY KEY(myid) );
How Can I Control the data type for each parameter ?? Or How Can I Change the data type of the parameter for the Deployed Stored Procedure ?? Or How Can I defined the new Data type ??
Or
What's the solution to this problem ??
Note : I get Error when I try to use Alert Statement to change the parameter Data type for the SP
ALTER PROCEDURE [dbo].[sp_AddImage] @ImageID [uniqueidentifier], @ImageFileName nText, @Image Image WITH EXECUTE AS CALLER AS EXTERNAL NAME [DatabaseAndImages].[StoredProcedures].[sp_AddImage] GO
I have a report parameter named "Schools" which display a list of schools. For example, Alo elementary school, Balo middle school and Calo high school.
When "Alo elementary" is selected the report only display students from that school along with other assessments data fields. same goes for other schools too. But I want to display different data fields for "Calo high school" when it is selected. It is not currently possilbe becasue I am using the same template for all types of schools. There some fields only should be displayed for "Calo high school" but not for any other type of schools.
I can accomplish this by creating two separate report, one for "Calo high school" and the other for other schools. But I want to accomplish this just by creating one report. So when "Alo elementary school" is selected it displays report with certain fields and when "Calo high school" is selected then it displays same fields as "Alo elementary school" but as well as some other fields too in the report. Is this possible? Need help.
In an existing SSRS 2012 report, I have a requirement for a user to be able to select by multiple school(s) and/or multiple grade(s). This is fine except certain schools like elementary have grade levels of KG to 06, Middle school has grades of 06 to 09 and high school has grades of 10 to 12. Thus for example, if a user has initially selected grades 11 and 12 and then they select an elementary school that has grades KG through 06, the 'grade level' selection would need to change.In other words, I am thinking of initially having the available and default values for the parameter called 'Grade' set to KG through 12. However if a school is selected that only has specific grade levels like elementary school, how can I override the original grade level and only allow the user to select grades that the particular school contains?
I want to Change parameter position in SSRS report.I need Start Date and End Date Parameter at same column so client can easily select Start Date and End Date.I have tried a lot but not succeed.
How Can I change the position of Start Date and End Date.I can't change order of other three parameter Select Institutions, Select Author and Course Pack Names parameter because they are internally related to each other(forward dependencies are there).
I have a requirement to show Day of week in parameter drop down list in different order, actual order is Monday to Sunday (Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday) in DayOfWeek dimension in cube.
But my requirement is to show Friday to Thursday(Friday,Saturday,Sunday,Monday,Tuesday,Wednesday,Thursday) in DayOf Week parameter drop down list and report table. How I can get this requirement done.
Presently using CONVERT(VARCHAR(11), [ExpiryDate], 100) to get close to the correct format.Only stumbled across this by accident so am assuming there might be better hidden 'treasures' .Formatting dates seems to be my biggest time-consuming activity and I just don't seem to get better at it!
I am working on reports in SSRS 2008 (not R2)... There are some reports with parameters that are hidden when the report is accessed through normal URL using ReportViewer.asx..The thing is that these hidden parameters need to be visible when the report is accessed using SSRS Report Manager.
We ran into weird/interesting issue with below details.
Version:Â Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64)Â Standard Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200):
We are using SQLCMD to run DDL script on our product database in below order. That script has below content.
step # 1 - database collation change (case -sensitive) statement as very first statement of the script step # 2 - Actual DDL SQL statements step # 3 - database collation change back to original (case insensitive)
When we execute all above 3 steps in single script using SQLCMD on our test_server#1 , it is successful but when same is being implemented on test_ server#2 , it is failing.We ensured that there is no other user accessing the db and setting on both the server are all default/basic. Separating out all 3 steps in 3 different script working fine. This is only problem when we combine them into single script and fire it using SQLCMD. If it is something related to session/transaction then we should hit same issue on our test_server#1 server as well but that is not the case.test_server#1 and test_server#2 has exact same database/data, just two different physical machine & SQL Server instance.
Hello, since a couple of days I'm fighting with RS 2005 and the Stored Procedure.
I have to display the result of a parameterized query and I created a SP that based in the parameter does something:
SET ANSI_NULLS ON SET QUOTED_IDENTIFIER ON CREATE PROCEDURE [schema].[spCreateReportTest] @Name nvarchar(20)= ''
AS BEGIN
declare @slqSelectQuery nvarchar(MAX);
SET NOCOUNT ON set @slqSelectQuery = N'SELECT field1,field2,field3 from table' if (@Name <> '') begin set @slqSelectQuery = @slqSelectQuery + ' where field2=''' + @Name + '''' end EXEC sp_executesql @slqSelectQuery end
Inside my business Intelligence Project I created: -the shared data source with the connection String - a data set : CommandType = Stored Procedure Query String = schema.spCreateReportTest When I run the Query by mean of the "!" icon, the parameter is Prompted and based on the value I provide the proper result set is displayed.
Now I move to "Layout" and my undertanding is that I have to create a report Paramater which values is passed to the SP's parameter... So inside"Layout" tab, I added the parameter: Name allow blank value is checked and is non-queried
the problem is that when I move to Preview -> I set the value into the parameter field automatically created but when I click on "View Report" nothing has been generated!!
I have two report , first is main report which is matrix and have one parameter User_ids which is multi value selection and my second report is basic chart of user_wise performance.
Now, my main report (matrix ) works fine for Multiple selection of users and i have putted one textbox on main report chart which has action properties set for chart report, when user click on chart button it must goes to chart with user selected in main report. Now , i have used expression for parameter to send it like ..
=join(parameter!user_id!value,",") which pass selected value to chartÂ
And when I am selecting single user it passing that value to chart parameter list but , when it is more than one user it errors with conversion failed when converting the nvarchar value '121,128' to data type int. But my chart also works when passing 121,128 in user parameter in preview of report .
I need "conditional" cascading parameters: In Report Manager when one changes parameter 1, parameter 2 get changed based on parameter 1. Optionally, one can also enter values to parameter 2 directly.
I was able to achieve this in SSRS 2000 (SP2) with the following setups. SSRS 2005 and SP1 no longer works - Parameter 2 always shows its default value regardless whether one select a value in Parameter 1 or not.
Parameter 1 available values: from query default values: non query (specify a value "<None>") Parameter 2 available values: Non query (no value specified) default values: from query (based on Parameter 1)
It seems to me that the default value in SSRS 2000 is considered as cascading parameter. But it is no longer the case in SSRS 2005.
Is this a SSRS 2005 bug? is there any other work arounds or suggestions?
