- Since the parameters are optional user can enter either one or can leave both blank.
- If user doesnot enter any values for SD (start date) and ED (end date), stored procedure should run select query replacing those values with wildcard character '%' or NULL
- If user enters SD, query should use @StartDate as the SD and GetDate() as the ED
- If user enters ED, query should use @EndDate as the ED and MIN() of the Date field as SD
I was able to write query which did almost everything as is stated above expect for incorporating NULLs
The query is as below
AS
IF ( @StartDate IS NULL)
Select @StartDate = MIN(DateInputted) from Document
Select
FName as 'First Name',
LName as 'Last Name',
ID as 'Student ID',
Orphan as 'Orphan',
DocumentType as 'Document Type',
DocDesc as 'Description of the Document',
DateInputted as 'Date Entered',
InputtedBy as 'Entered by'
From Document,DocumentTypeCodes
Where FName LIKE ISNULL(@FName,'%')
AND LName LIKE ISNULL(@LName,'%' + NULL)
AND ID LIKE ISNULL(@ID,'%' + NULL)
AND (DateInputted BETWEEN @StartDate AND ISNULL(@EndDate,GETDATE()) OR DateInputted IS NULL)
AND Document.DocTypeCode = DocumentTypeCodes.DocTypeCode
GO
Any help would be appreciated
Thanks in advance :)
I seem to have a little problem with my SQL. I'm attempting to use a an .NET grid-view to page a list of search results using an ObjectDataSource (ODS). It's a very simple search setup. The ODS retrieves the Search keyword from the query-string sending it to the BLL's GetResult method which then utilises the DAL's version and retrieves the result. Not all of them of course because I'm paging so it only retrieves the first page (Lets say the first 10 items). This part of the SQL works fine as the same SQL method is used else where on the site and it's well tested. But to to use the Paging function I'm using the SelectCountMethod attribute of the ODS. Again this gets the Search term from the QueryString and sends it too the BLL which retrieves the information from the DAL. Now this is where it starts playing up. The Sql count method is as follows and is run as a Stored Procedure: 1 ALTER PROCEDURE dbo.StoreName_Store_GetProductSearchCount 2 ( 3 @SearchQuery nvarchar 4 ) 5 AS 6 SET NOCOUNT ON 7 8 SELECT COUNT(*) 9 FROM StoreName_Products 10 WHERE Title LIKE '%' + @SearchQuery + '%' Nice and Easy. Not a Problem... Isn't it? When I run this query by selecting the database in the Server Explorer in VS2005 and running a 'New Query', it retrieves the correct results. (I only run this query from the Start of the SELECT Query in this mode, don't add the stuff above it)When I run this query through the website as intended and retrieves the int from the Stored Procedure, it always returns the entire count of the number of products in the table.At first I thought It might be a simple error with my caching system. Nope, it's not as after I purged it, it still returns the same value. I thought, well maybe just maybe the BLL or the DAL are some point converting it to this number but I'm quite sure it wasn't... and nope it wasn't that either because the ExecuteScalar method was found to be returning this number. So I ran the Stored Procedure by opening it up and simply right clicking the SQL Query and Executing it adding a value for @SearchQuery when it requested. Bingo. It's returning the full number of the products.So my question is... What's the deal? How can the same query return two completely different results? and most of all... How do I overcome this? Is this because it's in a stored procedure and I should be executing it as a SqlCommand from my DAL? I'm a bit confused. Is there a problem running this sort of query in a stored procedure that I don't know about and probably really should?Thankful for any answers,Regards,Luke
I am running a vba procedure ( adp file ) that executes successively 5 stored procedures . however it happens that the execution breaks at the middle of the code thus giving a situation where only 2 tables among 5 are updated.
Is it any solution to rollback transactions update already done before the code breaks due to error ?
I was thinking about combining all stored proc on a big one and use Begin transaction - commit transaction and rollback transaction ... however i am not sure wheter updates involving several tables can be handled on one transaction.
ID PID From To Code 1 1 14/02/07 17/02/07 X 2 1 17/02/07 19/02/07 X 3 1. 19/02/07 23/02/07 E 4 1 26/02/07 28/02/07 X 5 1 1/4/07 1/5/07 E 6 2 01/03/07 03/03/07 X 7 2 04/03/07 10/03/07 X 8 2 10/03/07 14/03/07 E
Result

I want to be able to create a select query on the above table. The table will show ID, PersonID (PID), From and to date, and code. If the code is X then the next €˜from record€™ should be the same date as the €˜to date€™. If the code is E then the next €˜to€™ date can be anytime after the previous €˜to€™ date. I want to be able to report on all record where there is a day difference between the previous €˜to€™ date. I.e. ID 4 and 7 €“ the previous records both have an X and there is at least a days difference between the dates.

Hi, I am working on an application in ASP.NET 1.1 and SQL Server 2005 as database.I wanted to use SQLCLR feature of SQL Server 2005. Is it possible that i write Stored Procedures in C# 1.1 and deploy on SQL Server 2005? as it is in case of C# 2.0. Please refer some good tutorial for it. Regards,Imran Ghani
Hi Guys, I need some help and suggestion to rewrite one of my screens (using ASP.NET) which is using stored procedure. The processing on this screen is taking more than 3 minutes (which i know is totaly unacceptable). I am making use of cursors within the stored procedure (SQL Server 2005). I really intend to get rid of cursors as they have their performance hit. I have been told to rewrite this screen (or the stored procedure) so i need some help for SQL Gurus. Following are the details: 1. This is a Monthly Employee Attendance Report on a day by day basis for any given month (maximum 31 days in a month) 2. The values (for each day) have to be computed at runtime and not stored. e.g. Since an employee may have signed in/out several times in a day 3. There are around 500 employees data im dealing with 4. The user will select any given department and employee's data for the respective department has to be displayed for any given month 5. If the user selects [All Department], the entire 500 employees have to be displayed on the screen 6. This report will look like an excel report on the screen i.e. Employee's basic info and record of 31 days (maximum days in a month) are displayed in one row for each employee 7. This report involves are 7-8 tables. 7 tables are for employees basic info whereas one table has the attendance record Kindly give me your suggestion on writing the SQL stored procedure. I cannot use any other option such as a real Excel Sheet or anything. I need suggestion on how to write this monthly report. By the way, we dont intend to Cache the data since the report can be viewed at anytime of the day, so fresh data is required everytime. Also the data for 500 employees may be too much to be cached. Also in the attendance table, we are dealing with approximately half a million attendance records. Thanks and waiting for your suggestions...
Want to write from a table variable to a text file from a stored procedure.Read about xp_cmdshell bcp etc. but worried because it's supposed to be a security problem and needs to be from a permanent database.Also am getting error "The EXECUTE permission was denied on the object 'xp_cmdshell'..."
1. Is xp_cmdshell a bad idea to use even if I get permissions ? 2. Can a "permanent" table be used in a stored procedure starting out fresh each time with 0 rows rather than use a table variable ?
Was wondering which is better, writing the SQL code within the execute SQL task or calling a SP from within it with respect to performance? and what is the best practice? Also is there any way to incoporate the logic of a cursur within SSIS?
Any way to have a process run that will not write its changes to the transaction log? I have a process that runs every three hours and has a huge impact on the transaction log (it becomes larger than the database itself). We do hourly backups of the transaction log and normally it is reasonably sized but when this process runs, it gets HUGE.
The process takes source data, massages it and writes it to summary tables. It is not something we need to track as we can recreate the summary tables if needed and it has no impact on the source tables.
Everything is driven through a stored procedure. Is there a way to run a stored procedure and tell it that nothing it does should be written to the transaction log?
hi, i am a nubie, and struggling with the where clause in my stored procedure. here is what i need to do: i have a gridview that displays records of monthly view of data. i want the user to be able to page through any selected month to view its corresponding data. the way i wanted to do this was to set up three link buttons above my gridview: [<<Prev] [Selected Month] [Next>>] the text for 'selected month' would change to correspond to which month of data was currently being displayed in the gridview (and default to the current month when the application first loads). i am having trouble writing the 'where' clause in my stored procedure to retrieve the selected month and year. i am using sql server 2000. i read this article (http://forums.asp.net/thread/1538777.aspx), but was not able to adapt it to what i am doing. i am open to other suggestions of how to do this if you know of a cleaner or more efficient way. thanks!
A table in my database has a field of type smalldatetime called "PeriodEnd". I want to write a simple stored procedure that gets records based on the 'PeriodEnd' field. When I run a query such as
Select * from mytable where PeriodEnd='30/06/1989'
I get an errror saying "The conversion of char data type to a smalldatetime data type resulted in an out-of-range smalldatetime value"
Do I have to use CONVERT in some way to alter my input value?
Well, I am venturing into new territory for me. I'm very illiterate when it comes to SQL Server and so I need assistance. I have the beginnings of my stored procedure, which is supposed to compare two dates/times and If they are not equal I need to kick off a DTS Package.
So, here's what I have so far (it returns two dates like I would expect):
CREATE PROCEDURE usrCompareDataDownload AS BEGIN SELECT MAX(ASP_ZZ_CHNG_TMST) FROM tbl_MaterialWeeklyData; SELECT MAX(ZZ_CHNG_TMST) FROM TV_ASP_DPUL_WKLY;
suppose,the type of the stored procedure's paramters is varchar .I hate to add parameterNames and types.If i can read the string of the stored procedure the get the paramterNames by operating text? public void storeOperate(string stringParameter,string name) { string[] strs=stringParameter.Split('&'); SqlConnection conn = new SqlConnection(getConnectionString.getconnectionString()); SqlCommand cmd=new SqlCommand(name,conn); cmd.CommandText=name; cmd.CommandType=CommandType.StoredProcedure; foreach(string str in strs) { cmd.Parameters.Add(".....",SqlDbType........).Value=str; //my trouble } conn.Open(); cmd.ExecuteNonQuery(); conn.Close(); cmd.Dispose(); }
I have a stored procedure where I am passing in two dates and looking for records between date one and date two. If I run the SQL statement in the query analyzer I get results back however if I try to pass the same to a stored procedure it returns nothing. Example: This returns a result when run in query analyzer
Select distinct Employeename from thisTable where someDate between '11/20/00' and '11/27/00'
Stored procedure is:
CREATE PROCEDURE sp_Employee_Report
@StartDate datetime, @EndDate datetime
AS Select distinct Employeename from thisTable where someDate between @StartDate and @EndDate
return nothing.
The someDate field is of date type datetime. Anyone know why this does not work in the stored procedure? Thanks for any help
We've researched this, and some people are stating convert to nvarchar first. I'd like to keep the date as a date.Here is how I am trying to call it:
Declare @FromDate as date Declare @ToDate as date Set @FromDate=Convert(date,'09-01-2015',110) Set @ToDate= Convert(Date,'10-13-2015',110) Select @FromDate
[code]...
How can I keep the date as a date and still pass it to stored procedure.
hi Experts,what is the purpose writing a date in the following format:where x.event_date >= {ts '1980-01-01 00:00:00'}versus like this:where x.event_date >= '1980-01-01 00:00:00'what benifit does it add to later form of writing?Thanks in advance.schal.
To set the scene I am using SQL 2012, in project deployment mode (SSIS Catalog rather than file system).I have setup an SSIS package to run a stored procedure which exports data for the last hour to a .tsv file and then FTP's the file to some other location via a sql agent job - This all works fine.However, I can see there may be a requirement to run the package with dates that need to be set i.e. in the event of a lost file of some other reason the package has not run and missed some of its hourly slots and the customer requires the files to be resent.
The stored procedure I am using has parameters for "DateOverride" - boolean), "start" and "end" dates (datetime) with defaults set "0" for "DateOverride" and null for the "Start" and "End" dates, I have built logic into the procedure which sets the dates if the parameters are null (as in the above to an hour before now). What I would like to be able to do (and this is to make it user friendly for support staff) is to be able to set parameters/variables in SQL agent with "DateOverride" set to "1" and the the dates I would like to be sent to the stored procedure "Start" and "End" parameters.
I did try using the parameters in SSIS which worked well when the values were true or false (0,1) but didn't work at all for the dates. If I left the dates as I had set them is SSIS it worked, but if I changed them (even if it was just changing the hour) the job errored/crashed and corrupted the job step leaving me the ability to only delete it.
hi, i am new in asp.net. .i have used sqlserver2005. in VS2005 file->new project->visual c#->Databse then select sqlserver project templates and click ok.. it shows new database reference dialog box in that i selected server name,use sqlserver authentication and database file. then click ok butoon it will shows the error that is "The Sql Server specified by this connection properties does not support managed objects.please choose another Sql server" suppose if u not able to understand above steps please refer this link http://www.sqlteam.com/article/writing-clr-stored-procedures-in-charp-introduction-to-charp-part-1 please don't mistake me.. thanks
Sorry, not sure if this is the right forum for this but hopefully you may be able to give me an answer.I have a website which fetches data from a SQL Server database using stored procedures, so I only grant execute rights to the proceduresto avoid granting select rights to the tables. This has been working fine but I would like to try writing this code in C# instead. I have writtenstored procedure that runs a select to test, and I am getting the error that the user has no rights to do select over the table.My question is, is the code writen this way (in C#) considered equivalent to dynamic SQL (which would require select rights over the tables)?Would this mean that I want to code my procedures in C# I need to grant select privileges over the tables to the db user?Thanks for your time
Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie exec dbo.DeriveStatusID 'Created' returns an int value as 1 (performed by "SELECT statusID FROM statusList WHERE statusName= 'Created') but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie: exec dbo.AddProduct_Insert 'widget1' which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID) I want to simply the insert to perform (in one sproc): SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID) This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example). My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert). Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?
Dear All,Please suggest some of the best practices for writing SQL serverstored procedures?I'm writing a business function (stored procedure), which callsmany-stored procedure one after another.I want this to be best optimized, so that speed can be very good.Suggestion in this regard will be appreciated.Thanks in advance,T.S.Negi
I just started looking into writing queries/SPs in C#. A simple SP looks like this.
public class ContactCode { [SqlProcedure] public static void GetContactNames(string lastName) { SqlCommand cmd = €¦€¦. €¦€¦ cmd.CommandText = "SELECT * FROM Person.Contact WHERE LastName = " + lastName; SqlDataReader rdr = cmd.ExecuteReader(); SqlPipe sp = €¦€¦€¦€¦..; sp.Send(rdr); } }
Since it's concatenating a dynamic SQL in the code, is SQL injection a concern or the CLR integration knows to take care of the input sanity? I know good programming practice is to validate input before it gets to this but it's necessary for CLR SPs to have the same robustness as normal T-SQL SPs when it comes to input parameter handling.
I’m currently writing a web application on student exam timetables, I’m using SQL Server 2005 as the back-end for the database.
At present, the case states that if a student is in one examination, he/she can’t attend, or be allocated another examination while the first examination is in place, which would result in a clash
The way I’m going to target this is by writing a stored procedure in SQL Server 2005 to return an error code, which I’ll translate using ASP,NET, however at present I’m having difficulty writing the SQL code. This is because…
I’m using SQL Server 2005 Management Studio; I created the tables using MS Access and upsized them using the wizard. I can now access my database, but having difficulty editing my tables and with code…
I have a database schema that has an Address table used to store addresses for different entities such as Customers and Employees. I want to reuse the same Address record between different Customers and Employees without duplicating any address information. I'm not sure what the best approach might be.
Should have I have seperate stored procedures on the Address table that update and insert new addresses, where each Address record remains immutable once created? (So the update stored procedure actually creates a new Address record if the data changes). These stored procedures would then be invoked by business logic and used in tandem with stored procedures that act on Customers and Employees to ensure that no address records are duplicated.
Or should I create a view on a Customer joined with Address, and similarily with Employee and Address, and have stored procedures that act on these views and ensure that no Address records are duplicated. Should I use instead of triggers to override the behavior of insert and update on the view to achieve these?
I'm rather lost as to what direction I should take. Any help would be much appreciated, thanks!

More Information for you to know: I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly. I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.
I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
