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.
I'm new to programming with the ReportViewer object and this issue has me stumped: it appears if you have some optional parameters in your report, and a way to refresh that report with different parameter values, the report "remembers" parameter values from previous calls to SetParameters() on subsequent renderings of the report. If a parameter is included in a call to ServerReport.SetParameters() on the first rendering, but not included in a subsequent call and the report is re-rendered, the previous value of the parameter (rather than the default value) appears to be used.
Here's a snippet of some test code I wrote within an ASP.NET 2.0 test application:
retVal[paramCount++] = new ReportParameter("Name", txtName.Text);
if (txtAddress.Text != "")
retVal[paramCount++] = new ReportParameter("Address", txtAddress.Text);
if (txtZip.Text != "")
retVal[paramCount++] = new ReportParameter("Zip", txtZip.Text);
return retVal;
}
The test report was written to simply echo back the values of the parameters that are specified. The report definition allows NULL to be specified for the parameters.
The test app was written so if I enter a blank value for Name, Address or Zip, the corresponding parameter does not get created in C# and does not get sent to the report server. If I view the report with all three values (parameters) filled in, I see the parameters echoed back to me in my simple report as expected. If I clear the parameter values the first time the report is rendered, none are sent to the report server and I get no values echoed back in my report, also as expected. I can change the values and click on the View Report button and see the new values for the parameters as expected. However, if I clear any previously-specified parameters and click on View Report, the previously-specified values for the ones that are now cleared are still displayed by the report.
So my question is: once a parameter has been sent to the report, how does one "unsend" it on subsequent refreshes? I know I can create the parameter and set its value to null...but I have a situation here where that can cause errors. It'd be better if I could simply leave out the unspecified parameters and have the report refresh and render as if I were rendering it for the first time.
i'm currently a student in computer information sciences, and i wanted to give my studying some more focus thus choosing dba. now i'd like to dba but be as broad as possible when i first start out my career. i know some programming languages and recently finished a C# book for doing .net development and a ASP.net book for scripting. but where should i go from here? should i just start studying ms sql server? what about a microsoft certification? i'm very curious to know where the next step in my studying should be, so anyone who was in my shoes, i'd love to hear any information you have to offer. TIA
Why does M$ Query Analyzer display all numbers as positive, no matterwhether they are truly positive or negative ?I am having to cast each column to varchar to find out if there areany negative numbers being hidden from me :(I tried checking Tools/Options/Connections/Use Regional Settings bothon and off, stopping and restarting M$ Query Analyer in betwixt, butno improvement.Am I missing some other option somewhere ?
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.
Hi,I'm finishing up a beginning SQL class where we learned on an Oracledatabase and the transition to working on SQL Server is easy. The next moreadvanced course will be in PL/SQL, but I know I will be working on SQLServer in the workplace, so my question is if I should take this course.Will I benefit from the basic philosophies that will be covered, or will itjust make a transition for me more difficult? Will it be partly a waste oftime and money and I'd be better served getting a book and self teachingmyself? I know that in a greater sense learning something isn't necessarilya waste, but I mean from the perspective of my goal of being able to use SqlServer, will this course be useful?thanks.
I am starting a class on SQL Server, and my school wants me to builddb's either on campus or remotely at my home connecting to their SQLServer Enterprise.Will I be okay to use Developer Edition at home to connect with anEnterprise-licensed SQL Server on campus, to build databases,sprocs, .net apps that connect to the database stored on my school'sserver?I would rather avoid the Express edition.thanks
I'm a kid and I'd like to know what kind of work a database administrator does. It would be great to learn from a real database administrator how you spend your typical day at the office. What are some of your main duties? Thanks so much in advance.
I need to calculate average of each student and then get the highest.
My try:
Code: SELECT Students.StudentId,Students.StudentName,AVG(Grades.Grade) AS avg_grade FROM Students s JOIN Grades g ON Grades.StudentId =Students.StudentId GROUP BY Students.StudentId, Students.StudentName
ORDER BY avg_grade LIMIT 1 FROM Students;
I encounter problem with this code, maybe it's Completely wrong...
CREATE TABLE [dbo].[Student]( [StudentNumber] [varchar](50) NOT NULL, [Name] [char](50) NOT NULL, [Contact] [int] NOT NULL, [Address] [char](50) NOT NULL, [DateOfBirth] [datetime] NOT NULL, [YearEnrolled] [int] NOT NULL, [Year] [int] NOT NULL;
And insert the following data:
INSERT INTO Student VALUES('IT123456X', 'Ahmad Adam','05-18-1997', '33 Mangis Rod', 19970518, 2013, 1); INSERT INTO Student VALUES('IT334455U', 'Mary Tan', '01-23-1996', '51 Koon Seng Road', 23-01-1996, 2012, 1); INSERT INTO Student VALUES('BS123456X', 'Samuel Lee', '03-30-1997', '2 Joo Chiat Lane', 30-03-1997, 2013, 1); INSERT INTO Student VALUES('BS234234Z', 'Nathaniel Koh', '12-08-1997', '5 Stll Road', 08-12-1997, 2013, 1); INSERT INTO Student VALUES('BS987987F', 'Siti Faridah', '07-04-1995', '3 Duku Road', 04-07-1995, 2011, 3)
How do i calculate the age and how can i group by the StudentNumber like 'IT%'
We have SQL database now a days we are planing to update our students ID Records but i don't know the exact query for this. Table format is below
StudentID Name 500132253/Prep Aslam 112344883/Prep Ali 451132537/Prep Ahmed
Now i want to update only the grade from prep to KG-1 without update the registration number only prep to kg-1. in one column there is student register number and after slash the grade.
I am stumped on a set-based approach for this one.
A cursor approach is straightforward enough, but i want to avoid that.
Here's my table:
create table StudentScores ( id int primary key identity(1,1), student_id int not null, score int not null )
with some sample data:
insert into StudentScores (student_id, score) select 1, 10 union all select 1, 29 union all select 1, 50 union all select 1, 53 union all select 1, 45 union all select 1, 10 union all select 1, 29 union all select 1, 50 union all select 1, 53 union all select 1, 45 union all select 1, 88 union all select 2, 23 union all select 2, 54 union all select 2, 55 union all select 2, 34 union all select 2, 56 union all select 2, 78 union all select 2, 23 union all select 2, 54 union all select 2, 55 union all select 2, 34 union all select 2, 56 union all select 2, 78 union all select 2, 23 union all select 2, 54 union all select 2, 55 union all select 2, 34 union all select 2, 56 union all select 2, 78 union all select 2, 98
What I want is, for each student, what is their 90th percentile score?
For a given single student, one possibility would be:
declare @studentid int set @studentid = 2 select top 1 @studentid as student_id, a.score as [90th percentile score] from ( select top 90 percent score from StudentScores where student_id = @studentid order by score asc ) as a order by a.score desc
But I want this for all students, and not use a cursor.
I am trying to find out the the Average number of contact hours per student. in Reporting Services 2005. The contact hours is the in the Totaltime field
Is this formula correct
=Sum(Fields!TotalTime.Value)/Avg(Fields!TotalTime.Value) is in the =Fields!StateServices.Value Group
I have a csv that contains attendance records that I get daily from a 3rd party grade book solution. I need to import directly into the attend table in our student database.
The file is setup as follows, School Year, school number, student_id, absence date, absence code, course number, section number.
I need to check the student schedule to see if they are scheduled for that class when the import runs. So if they had a schedule change in the middle of the day it won't post attend to a dropped class.
I have done something similar to this before with the way I export teachers out to our grade book. I have it check the master schedule to see if the teacher is teaching at least one class, that way it won't export tutors and office staff to the grade book. I used the script below to do that but not sure who to apply it to a bulk insert.
Code: Script Used to export teachers note last four lines, checks master USE [GSchool] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
[Code] ....
Secondly I need to check the date of the record and overwrite a record if one already exists for that exact course and section for that student, I need this because if they make changes to a previous day from absence un excused to excused I need to get rid of the unexcused by overwriting it.
One more thing that would be nice but is optional, is there a way to send log of errors on the import via email?
i am having problem putting this query to calculate students grade using the condition and legend bellow.
WHEN EXAMS BETWEEN 75 AND 100 THEN 'A' WHEN EXAMS BETWEEN 70 AND 74 THEN 'AB' WHEN EXAMS BETWEEN 65 AND 69 THEN 'B' WHEN EXAMS BETWEEN 60 AND 64 THEN 'BC'
In my query, I am showing Student Record and also want to retrieve the last class attended by the student using JOIN to the table (ClassHistory).
Master ID Student_Name 1 Arindam 2 Brenda 3 Callie
(ClassHistory) ID Class Year 1 4 2003 1 5 2004 1 6 2005 2 4 2003 2 5 2004 3 4 2003
DESIRED RESULTSET ID Student_Name Class Record 1 Arindam 6 2 Brenda 5 3 Callie 4
The result is like - Arindam last class was Class 6, while Brenda was in Class 5 and Callie was in class 4.
Please note that the query will b part of a larger query and the Class record to be retrieved from ClassHistory if possible need to be retrieved through JOIN.
I have an 'ID' column. I'm up to about ID number 40000, but not all are in use, so ID 4354 might not be in any row. I want a list of all numbers which aren't in use. I want to write something like this:
select [numbers from 0 to 40000] where <number> not in (select distinct id from mytable)
I can fetch the counts for total present and absent
Query i have tried is
Declare @StudentId Uniqueidentifier ='0B2D4D41-8D33-4D79-A981-03E0F093F458' Begin select A.StudentId ,A.Date,Count(Date)Total,B.Guid,
[Code] ....
AS result of this query i get the data.Present count and Absent count from date inserted in Dailyattendance tables.
SO my problem is if the student have promoted to next class then by this query it will count the before year also how do i need to calculate the count according to the Class StartDate and Enddate as i mention in the Class Details table what will be the query.
I'm currently on a company with an ms sql server 2000. I'm looking into the indexes and tables to see if there are some bottlenecks there but the LogicalFramentation is very low in the index I have searched.
However, this table has a logicalFragmentation of 99,9215698242188 which I get when I do DBCC SHOWCONTIG ([TInsurance]) WITH TABLERESULTS. Is that a value to be trusted or not to be trusted since this does not check an index? If it is, how do I defrag a table? I know only how to defrag an index. (example: DBCC INDEXDEFRAG (MFSSEK,[TInsurance], PK_InsuranceID) )
Tipps, suggestions, help, all is very wellcome! :-)

I have seen several examples explaining the fact that a tablecontaining a field for each day of the week is for the most part anarray. An specific example is where data representing worked hours isstored in a table.CREATE TABLE [hoursWorked] ([id] [int] NOT NULL ,[location_id] [tinyint] NOT NULL,[sunday] [int] NULL ,[monday] [int] NULL ,[tuesday] [int] NULL ,[wednesday] [int] NULL ,[thursday] [int] NULL ,[friday] [int] NULL ,[saturday] [int] NULL)I had to work with a table with a similar structure about 7 years agoand I remember that writing code against the table was pretty close toHell on earth.I am now looking at a table that is similar in nature - but different.CREATE TABLE [blah] ([concat_1_id] [int] NOT NULL ,[concat_2_id] [int] NOT NULL ,[code_1] [varchar] (30) NOT NULL ,[code_2] [varchar] (20) NULL ,[code_3] [varchar] (20) NULL ,[some_flg] [char] (1) NOT NULL) ON [PRIMARY]The value for code_2 and code_3 will be dependently null and they willrepresent similar data in both records (i.e. the value "abc" can existin both fields) . For example if code_2 contains data then code_3 willprobably not contain data.I do not think that this is an array. But with so many rows wherecode_2 and code_3 will be NULL something just does not feel right.I will appreciate your input.
Does anyone know how to identify the hottest, most active tables in adatabase?We have hundreds of users hitting a PeopleSoft database with hundredsof tables. We are I/O bound on our SAN, and are thinking of puttingthe hottest tables on a solid state (RAM) drive for improvedperformance. Problem is: which are the hottest tables? Would like todo this based on hard data instead of developer/vendor guesses.Any suggestions are much appreciated.
