How Do I Pass A Paramater?
Oct 19, 2006Hey everyone I'm having trouble finding a way to pass a particular paramater, my main goal of this is to create a custom paging and sorting control for the DataList, but we wont worry about all the un-nessesarry code, here is what I am dealing with... Sub Page_Load()
Dim Conn As SqlConnection
Dim Query As String
Dim SqlComm As SqlCommand
Dim myDataReader As SqlDataReader
' Define connection object
Conn = New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
' Define query to retrieve main category values
Query = "SELECT [productMainCategory] FROM [User_Products] WHERE [productMainCategory] = @productMainCategory"
' Define command object
SqlComm = New SqlCommand(Query, Conn)
' Open connection to database
Conn.Open()
' Create DataReader
myDataReader = SqlComm.ExecuteReader()
' Iterate through records and add to array list
While myDataReader.Read()
IDList.Add(myDataReader("productMainCategory"))
End While
' Close DataReader and connection objects
myDataReader.Close()
myDataReader = Nothing
Conn.Close()
Conn = Nothing
' If page has not been posted back, retrieve first page of records
If Not Page.IsPostBack Then
Paging()
End If
End Sub
The Entire Point to this bit of code is to open a connection to the database find the category productsMainCategory, count all the fields with the Name 3D Art --> and save that number into an Array List where I will be using it later on in my code......The big old problem here is that it counts every single field in the productsMainCategory, Columb.........I need to figure out how to pass it a parameter so that it only counts my 3D Art --> fields, I have tried using this bit of code but nothing SqlComm.Parameters("@productMainCategory").Value = "3D Art -->"Does anyone have any ideas of how I might go about donig this?Thank You..
How Can I Return Everything While Using A Paramater
Jun 26, 2007I guess a pretty basic sql question here. I am using tableadapters. And some of the queries have multiple parameters. But often a parameter is at a default or null - wherein I'd like to be able to pass it in and have it not filter at all - ie., return everything.
Simple example:
Select * from ReportsWhere ReportID = @ReportID
If I have a dropdownlist of reports where the values are ReportIDs - but the topmost unselected value is say "", then the results will be generated by
Select * from ReportsWhere ReportID = ''
Whis not what I want. What I would want is simply
Select * from Reports
or
Select * from ReportsWhere ReportID = ReportID
So how can one setup say an ObjectDataSource or somehow handle this where I don't need to use dynamic sql to expand/contract my where clause?
Really need hlpe on this and hope I've made my question reasonably clear. Thanks.

Multiple Paramater Search
Sep 23, 2005I have a search page, containing 3 drop down lists. Theses are used to match data in 3 seperate collumns of a table.I can get the search to work when all boxes are completed, but I need to be able to leave some blank.A similar question was asked in http://forums.asp.net/626941/ShowPost.aspxAnd a very good solution was give: http://www.sqlteam.com/item.asp?ItemID=2077But I don't seem to be able to get any of these examples working!If I use the SET @SQL method, I get an error message saying that my input parameter has not been declared, when it has.When I use the COALESCE method, there is no data returned.(I am passing the data drop down list data fin the search page through the query string to a results page).Does anyone know of any other examples, or sample coding??Thanks...
View 2 Replies View RelatedRemoving A Paramater Gives An Error
Feb 6, 2006
Removing a parameter on a Reporting services report based on a 2005 AS cube results in an error:
[rsParameterReference] The Value expression for the query parameter €˜KalenderHierarchieJaarMaand€™ refers to a non-existing report parameter €˜KalenderHierarchieJaarMaand€™.
On the dataset, the parameter still exists. The error still occors after removing the parameter overhere too.
Steps to reproduce:
Build a raport based on a cube. Make a parameter in the dataset. check if the parameter works. Save the report and remove the parameter via the menu: Report> Report parameters > select the parameter and choose [Remove]. go to the "Preview" tab.
Has anyone found a work-around for this?
Thanks in advance,

Retrieving Output Paramater After Insert
Sep 14, 2006Can some one offer me some assistance? I'm using a SQLDataSource control to call a stored proc to insert a record into a control. The stored proc I'm calling has an output paramater that returns the new rows identity field to be used later. I'm having trouble getting to this return value via the SQLDataSource . Below is my code (C#): SqlDataSource1.InsertParameters["USR_AUTH_NAME"].DefaultValue = storeNumber;SqlDataSource1.InsertParameters["usr_auth_pwd"].DefaultValue = string.Empty;SqlDataSource1.InsertParameters["mod_usr_name"].DefaultValue = "SYSTEM";SqlDataSource1.InsertParameters["usr_auth_id"].Direction = ParameterDirection.ReturnValue;SqlDataSource1.Insert();int id = int.Parse(SqlDataSource1.InsertParameters["usr_auth_id"].DefaultValue); below is the error I'm getting: System.Data.SqlClient.SqlException: Procedure 'csi_USR_AUTH' expects parameter '@usr_auth_id', which was not supplied. Has anyone done this before and if so how did you do it?

View 6 Replies View RelatedDeselect All On Multivalue Paramater When Other Value Is Chosen

I use "All" as default value in my parameters, my parameters are multivalue.
Now if a user chooses a value it will mark the value but the All will also remain marked. Isn't there a way that it deselects the all when one or more individual values are chosen ?

CLR-Based Trigger? Recursive Trigger? Common Table Expression?
Nov 14, 2006Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

}
//Helper function that takes a Table of the Primary Key Column Names and the modified rows Values
//and builds a string of the form "<PKColumn1Name=Value1>,PKColumn2Name=Value2>,......"
public static string PKStringBuilder(DataTable primaryKeysTable, DataRow valuesDataRow)
{
string temp = String.Empty;
foreach (DataRow kColumn in primaryKeysTable.Rows)//for all Primary Keys of the Table that is being changed
{
temp = String.Concat(temp, String.Concat("<", kColumn[0].ToString(), "=", valuesDataRow[kColumn[0].ToString)].ToString(), ">,"));
}
return temp;
}
}
The trick was getting the Table Name and the Primary Key Columns.
I hope this code is found useful.
Comments and Suggestion will be much appreciated.

I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i
where
--specific USER

View 3 Replies View RelatedModifing The Row That Invokes A Trigger From Within That Trigger
Jul 23, 2005When a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.

View 4 Replies View RelatedUpdate Trigger Behaviour W/o A Trigger.
May 30, 2008Hi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,
Drop Trigger With A Variable Trigger Name
Sep 20, 2007
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers.
The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name
how do i get around this?
thanks in advance

Trigger Doesn't Log Into The Audit Table If The Column Of Table Has Trigger On Is Null
Jan 23, 2008
Hi,
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname
Thanks,
leo
