I have a search page that allows users to type/select values contined within the entry they're looking for. My SELECT statement returns columns in a table that get compared to the user input. So if someone selected Status (Open) then all of the 'Open' Request entries should populate the search page. How do I phrase the SELECT statement to compare values if the user gives them, but ignore the fields where no data was input when it's searching? So a search where no values were entered would return every Request Entry instead of an error; no entry.
Let's say I have a table with 3 fields: an ID field (primary key, set as an id field, etc.), a Name field (nvarchar50), and an Age field (int). I have a form that has three elements: DropDownList1: This drop down list contains 3 choices- "=", ">", and "<". Age: This text box is where someone would enter a number. Button1: This is the form's submit button. I want someone to be able to search the database for entries where the Age is either equal to ("="), greater than (">"), or less than ("<") whatever number they enter into TextBox1. The code-behind is shown below. The part I'm confused about is that if I load this page, the query works the -first- time. Then, if I try to change the parameters in the form and submit it, I get the following error: "The variable name '@Age' has already been declared. Variable names must be unique within a query batch or stored procedure." Any help would be appreciated. Here is what I'm using in my code behind: protected void Button1_Click(object sender, EventArgs e) { System.Text.StringBuilder sb = new System.Text.StringBuilder(); sb.Append("SELECT * FROM People WHERE Age "); switch (DropDownList1.SelectedValue) { case "=": sb.Append("= "); break; case ">": sb.Append("> "); break; case "<": sb.Append("< "); break; } sb.Append("@Age"); SqlDataSource1.SelectCommand = sb.ToString(); SqlDataSource1.SelectParameters.Add("Age", TypeCode.Int32, Age.Text); }
I have to produce a report to calculate no of days based on user input start date and end date. I have tried to explain below.
say for eg: in the tables I have emp name user 'Phani' started work from - EStart 20/11/2014EEnd 10/01/2015 - total days --datediff within his work period he did different roles:
PhaniMarketing (prSt Date) 20/11/2014prE date (28/11/2014) Total 9 days PhaniAdmin (prSt Date) 29/11/2014prE date (20/12/2014) Total 22 days PhaniCRM (prSt Date) 20/12/2014prE date (10/01/2015) Total 22 days Total days 53 Days
For this :
I calculated datediff + 1 and got sub jobs days BUT
say financial director wants to see Title of 'Sub Jobs' with 'Days' from 1st Dec to 31st Dec
so on paper I calulated as :
1-31 Dec 2014 PhaniMarketing NULL (Do not fall in Req Dt) PhaniAdmin 20 (Deduct 2 days of Nov & calculated 20 days of Dec) PhaniCRM 11 (Deduct 20 days of Nov and deduct 11 days of Jan so for Dec , we got 11 days) Total days 31
HOW CAN I USE Case statement to calculate days for given start date and end date. I have to include all three totals, 1 for Job dates, 2, subjobs dates, 3 cal of days for a requested period.

Can anyone tell me how to search an SQL database for a given key word in a textbox? I basically have a database that has a qualifications column and this column needs to be searched for the data given in the textbox. Which is the best method to search for the data? Is it a simple SQL query or an XML based search engine type? Can anyone give any suggestions regarding this? If XML is efficient then how do I use it to query my database, as I'm pretty new in XML based searching.Thanks
I am building a pretty simple intranet application where we need to be able to track changes to tables. The tracking feature do not need to be very advanced, we just need to see who changed something and what it was. Therefore I decided just to use a trigger based solution, but need some input/advice since my SQL skills is somewhat lacking.
Consider the following (mock-up) schema:
-- My content table CREATE TABLE [Content]( [ContentGuid] [uniqueidentifier] NOT NULL PRIMARY KEY DEFAULT (newid()), [Data] [nvarchar](4000) NOT NULL, [ChangedBy] [nchar](10) NOT NULL, [MaybeNull] [int] NULL )
-- My history table CREATE TABLE [History]( [ChangedTable] [nvarchar](50) NOT NULL, [ReferenceGuid] [uniqueidentifier] NOT NULL, [ChangedBy] [nchar](10) NOT NULL, [ChangedOn] [datetime] NOT NULL DEFAULT (getutcdate()), [IsDelete] [bit] NOT NULL DEFAULT ((0)), [Changes] [xml] NOT NULL ) ON [PRIMARY]
-- My insert/update trigger CREATE TRIGGER [RecordChangeOnInsertUpdate] ON [Content] AFTER INSERT,UPDATE AS BEGIN SET NOCOUNT ON;
DECLARE @Changes xml SET @Changes = (select * from [inserted] for xml raw ('Content'), elements xsinil)
INSERT INTO [History] ([ChangedTable] ,[ReferenceGuid] ,[ChangedBy] ,[ChangedOn] ,[IsDelete] ,[Changes]) SELECT 'Content', ContentGuid, ChangedBy, getutcdate(), 0, @Changes FROM [inserted] END
-- My delete trigger CREATE TRIGGER [RecordChangeOnDelete] ON [Content] AFTER DELETE AS BEGIN SET NOCOUNT ON;
DECLARE @Changes xml SET @Changes = (select * from [deleted] for xml raw ('Content'), elements xsinil)
INSERT INTO [History] ([ChangedTable] ,[ReferenceGuid] ,[ChangedBy] ,[ChangedOn] ,[IsDelete] ,[Changes]) SELECT 'Content', ContentGuid, ChangedBy, getutcdate(), 1, @Changes FROM [deleted] END
I have decided to use the "one history table for all table changes" method. The changes for a row is stored in a xml column which obviously limits the total size of columns in a table being tracked, but that is not a problem in my application. In general I like this set up, since I will be able to change the schema continuously without having to change the triggers, and since the application will probably evolve a lot over the coming months this is pretty important to me.
EDIT: I should add that all the tables I will be tracking have a uniqueidentifier column. This makes it possible to related table rows in the different tables being tracked with their history.
A few concerns with the above SQL:
- Can the inserted/deleted table change between "SET @Changes = (select * ..." and the "INSERT INTO ..." statement, such that the data is not valid? If so, how to work around that?
- If I were to (hypothetically) perform a "UPDATE [Content] SET [Data] = 'something'", not only is my update trigger called once for each row updated, but the XML added to the inserted row in the history table ([History].[Changes]) represent all the rows updated in the batch update. How do I get around this?

I need a Query for calculating the fiscal_week based on the input dates (start_date and end_date), though I got a query from this forum, it is not giving me exact result.
the sample is in the excel file with the attachment.
In the excel:
First tab tells you the raw_data what I am using to find the Fiscal_week Second tab tell you the data where i found the mistake, and how I am expecting the output.
I also have attached the query I have got from this forum, query I have modified for fiscal week.
I'm trying to create a fairly simple custom transform component (because I've read that's the easiest one to create) which will take one column from a flat file source and based on the first row create the output columns. I'm actually trying to write a component that will solve the now well known problem with parsing CSV files in SSIS. I have a lot of source files and all have many columns so a component that can read in the first line from the CSV file and create the output columns automatically will save me lots of time when migrating the old DTS packages.
I have the basic component set up but I'm stuck when trying to override the OnInputPathAttached method because I don't know how to use the inputID to get the first line from the input (the buffer). Are there any good examples for creating output columns dynamically based on the input buffer? Should I just give up on on the transform and create a custom source component instead?
I have 2 tables in my report, a multi value parameter (tp_title) is passed to the report. I am trying to hide the first tablix with this expression in the visiblity option of the tablix properties.
=IIF(Parameters!tp_Title.value = "Financial Years" or Parameters!tp_Title.value="ALL", False,True )
I get the error: The Hidden expression for the tablix ‘Tablix1’ contains an error: Overload resolution failed because no Public '=' can be called with these arguments: 'Public Shared Operator =(a As String, b As String) As Boolean': Argument matching parameter 'a' cannot convert from 'Object()' to 'String'.
When I render the report. How the tablix can be made invisible based on the parameter?
Is it possible to allow user input via a Reporting Services Report? What I mean is could a report be created that would allow someone using the report to enter a number that would be written to the SQL database?
I'm seeing where previous developers have used a single stored procedure for multiple reports, where each report required different columns to be returned. They are structured like this:
CREATE PROCEDURE dbo.GetSomeData (@rptType INT, @customerID INT) AS BEGIN IF @rptType = 1 BEGIN SELECT LastName, FirstName, MiddleInitial
[Code] ....
As you can see, the output depends on the given report type. I've personally never done this, but that's more because it's the way I learned as opposed to any hard facts to support it.
Hi, Just wondering if I could make sure that "hackers" don't tamper with my querystring - which is a parameter for a SQL query. i.e... Dim ListOfValues as string = request.querystring("listOfValues")
'Output would be this: 324234,5445,554654,45632,SQL command : Delete From table where product_id IN (@ListOfValues)
How can I validate it so that hackers can't add any characters other than 'numbers' and ' , ' to the sql parameter? I have tried to tryparse the 'ListOfValues ' as an integer - by replacing "," with "" but an integer overflow occured. Any questions or ideas? Thanks
I am new to ASP.NET so pordon me if my questions seems to be stupid.
I was given an assign to develop a ASP that would return results from a SQL server.
The problem is that part of my query to the SQL server comes from the webform
select a.invnum, a.invdate, a.duedate, a.invamt,a.payamt from vpshead a inner join vendors b on (a.vendnum = b.vendnum) where (a.vendnum = " & user.text & " ) and (b.vendpass = " & Pass.text & " ) and (a.payflag <> 'V') and ( (a.invamt <> 0) or (a.payamt <> 0) )and (a.chkno = '') order by a.invdate"
As your can tell I am using the user.text and Pass.text in my query which will come from the web form.
well here's a problem that I encountered, i got a textbox that is used to store the Date of Birth of a user. So when user keys in something, it is store as a string. However i wish to convert it into a datetime so that i can store it into my database. Anybody know of a way to help? i've tried countless methods but doesn't seem to work. Please give me a hand guys.... Thanks
Hello. I'm using SQL query analyzer to run some queries against anSQL2000 DB. Unfortunately, my previous SQL experience is some OralceSQL I took in school.To put it simply, I'm trying to write a query to pull records thatmatch a variable input. In Oracle, I'd use a substitution variablelike this...SELECT * FROM jobs WHERE jobid = &job_id_to_query;Is this possible under SQL2000? Is this only a feature of SQL*Plus?TIARich
I want to pull dates from my database that are between to set dates i have written a query that does this which looks like this: "SELECT OCH_ID, empno, Selected_OCD, Start_Time, End_Time, Selected_OCDay, Selected_DOM, Selected_Month, Selected_Year FROM dbo.ICT_On_Call_Hours WHERE (CONVERT (datetime, LEFT (Selected_OCD, 2) + '/' + SUBSTRING(Selected_OCD, 4, 2) + '/' + RIGHT (Selected_OCD, 4)) >= CONVERT (datetime, LEFT ('12/02/2007', 2) + '/' + SUBSTRING('12/02/2007', 4, 2) + '/' + RIGHT ('12/02/2007', 4))) AND (CONVERT (datetime, LEFT (Selected_OCD, 2) + '/' + SUBSTRING(Selected_OCD, 4, 2) + '/' + RIGHT (Selected_OCD, 4)) < CONVERT (datetime, LEFT ('14/02/2007', 2) + '/' + SUBSTRING('14/02/2007', 4, 2) + '/' + RIGHT ('14/02/2007', 4)))" This works when the dates are included in the statement but when i try and use parameters to pull them in like this: "SELECT OCH_ID, empno, Selected_OCD, Start_Time, End_Time, Selected_OCDay, Selected_DOM, Selected_Month, Selected_Year FROM dbo.ICT_On_Call_Hours WHERE (CONVERT (datetime, LEFT (Selected_OCD, 2) + '/' + SUBSTRING(Selected_OCD, 4, 2) + '/' + RIGHT (Selected_OCD, 4)) >= CONVERT (datetime, LEFT ('@Choice1', 2) + '/' + SUBSTRING('@Choice1', 4, 2) + '/' + RIGHT ('@Choice1', 4))) AND (CONVERT (datetime, LEFT (Selected_OCD, 2) + '/' + SUBSTRING(Selected_OCD, 4, 2) + '/' + RIGHT (Selected_OCD, 4)) < CONVERT (datetime, LEFT ('@Choice2', 2) + '/' + SUBSTRING('@Choice2', 4, 2) + '/' + RIGHT ('@Choice2', 4)))" I then recieve the following error message why is this? ERROR -------------------> Syntax error converting datetime from character string. Any Help would be greatly appreciated thanks
Hi folks, i am lookin for an option in the QA to take user input while executing a query. just like we do in SQLPLUS: SELECT * FROM dept WHERE deptno=$abc here it would ask me for the deptno. I guess it's a very handy feature and we could test our variables and calculations withing the procedures etc.
I would like to setup a query where the user is firstly prompted to input the information e.g. if they are trying to locate a particular person from a telephone database they would be prompted to enter the surname for that person.
I'm trying to do something simple that has turned out to be a frustrating problem. I have a field in my report that needs to be populated by user input. Based on this user input, I will use the field in a calculation. The simple solution to me, was to create a custom assembly that has a function that uses Console.Write("Input Data") and Console.readline() to assign the input to a string, and then return that string to the report. This works fine in a test console application, but when I copy and paste the code to my custom assembly, it returns #Error to the report. I've debugged, and found that when I hit F10 on Console.Write("test"); it skips right over it, and nothing happens. It also skips over Console.readline(); with nothing happening. This makes me unable to take the user input and set the textbox equal to that value.
Am I doing this completely wrong? Is there something I'm missing, or just not understanding correcly? It seems like reporting services has to have this option. I'd really appreciate some advice. Thanks!
I am sure this has been asked a thousand times before in a thousand different ways, but here goes...
I am in need of the ability to prompt users for a From Date and To Date to insert into a WHERE clause in SQL queries. What is the easiest least painful way of accomplishing this? A great many of our customers utilized SQL Server Express or MSDE, so they do not have the full gambit of SQL tools handy. Believe me when I say that I have searched high and low across the internet for this solution. I was hoping I might be able to accomplish this through VB Script or J Script. Or, anything reasonable.
