I'm using cursor to select a list of records in sql server 2005
There are 80+ columns in the result, the cursor parameters named as @pn1,@pn2,@pn3... @pn12. @pid1,@pid2,@pid3.... @pid12
[Code]....
The above code rotates the parameter ('@pn' + loop id) to get the cursor parameter value.
I am curious, if it's better to iterate through a set of records using cursor or using a WHILE (SELECT ..) ? I have read that cursors can be expensive, so may be WHILE (SELECT..) is a better approach.But I am not sure ?
EXAMPLE OF WHILE (SELECT..) is as below
DECLARE @warehouseId INT
DECLARE @warehouseIds TABLE ( WarehouseId INT )
[code]...
consider the follwing table, this table actually shows which id was given a new id
i.e 11 was assigned 13
again 13 was assigned 15
15 was reassigned 17....and so on actually 11,13,15,17,19 represent the same user (hope u understood)
customerId rejoiningId
11 13
13 15
15 17
20 21
17 19
48 50
21 25
i need to loop through all the rows and find the relation that which all ids are interlinked
say the user enters the rejoining id -13,hence the result should come out to be as 11,13,15,17,19
if user enters 21result should be 20,21,25
it takes a bit of looping statements in query that i couldnt figure out

When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.

to loop through each field in a record to test for a value and then set a flag at the end of each record if an instance of this value occurs in any fields?I have a table where some fields values are have a *c* at the beginning of the text eg "*c* value" . What I would like to do is run a select query off the table and at the end of each record have a field called "Change Flag" and a value of "Changed" or "No Change" depending if a *c* has been encountered.
There are a number of tables to run this against all with differening numbers of fields/
public void ModifyEnter()
{
combo1.Attributes.Add("onkeydown", "if(event.which || event.keyCode)" +

Table1 - T1Col1(varchar) T1Col2(int) T1Col3(varchar)
Table2- T2Col1(varchar), T2Col2(varchar), T2Col3(int)
Table3- T3col1(varchar),T3col2(varchar)
For every record in Table1 I need to loop through top 10 records in Table2 - check this condition if( T1Col2 element & T2Col3 element)/T2Col3 element = 1 and insert T1Col1,T2col1 in to Table3
using sql server 2005.
i need to query a table which normally will return multiple records for the id and I need to loop through probably using a cursor and pull values out from each record to make a string.
what is the syntax for this? i've seen cursors using a set number (EX: loop through 5 times) but I need to create a query so that I can loop through once for each row returned from my query.
I have developed a dynamic menu with asp.net, everything is believed correctly. The problem that I have is that there are items of the menu that have the empty route, that is to say NavigateUrl = "", and however the cursor that he/she takes the mouse when it passes above the links it is hand, and I want that, if he/she doesn't have route to which to go takes cursor=text.
I have proven putting it in the leaf of styles, putting it for code, but anything, when I pass the mouse above the text that puts in the menu it puts me the cursor with hand. I believe that the problem is that he/she is taking the style of the hyperlink, but this style I don't want to change.
I want some sample code that will loop through records of table variable using a forward only cursor.

When can I use Stored Procedure? Is this useful for looping into multiple SELECT statements to return single value? How? Can anyone post some sample codes?

View 5 RepliesI have a stored procedure which handles a SELECT query on an SQL 2005 table. Works fine. Now I need to add a bunch of parameters to the query--these are all boolean, with checkbox web controls on the .aspx page to set the parameters true or false, and bit columns in the SQL table. These parameters need to be optional, so that parameter doesn't filter out any records unless it's checked. Here's the original sproc:

Can I just add on all those boolean parameters like so?

I've used a sql data source to execute an insert stored procedure into my sql database. This time though, I want to execute the sp from my code behind. BUT, I'm stuck on the parameters and how to pass in the ones for the insert, and return one parameter, which is the identity of the row just inserted. The error I'm getting is. I'm missing something, but I don't see what... I think it's with the input/output parameters...

I have a table with 4 columns.The first column is a list of teams.The other three columns specify whether the team member with the particular id is present on any particular day .Say for example in the third row the running Team has 2 and 3 which means team member with the id 2 and 3 are present.Multiple values are seperated by the pipe symbol '|'.I have a Query like this
Select Teamname from tblTeam where Running not like '%|2|%' and Running not like '%|3|%' and Running not like '%|7|%' and Biking not like '%|1|%' and Biking not like '%|4|%' and Biking not like '%|7|%' and shooting not like '%|3|%' and shooting not like '%|4|%' and shooting not like '%|7|%' Basically i am searching the columns with like clause.The search criteria for each column may vary.In the above query i am searching for Teams where Running column does not contain 2,3 and 7,Biking column does not contain 1,4 and 7 and the shooting column does not contain 3,4 and 7. I would like to set a stored procedure where i would be able to pass 3 set of parameters from the code behind(I am using VB.net) for Running column search,Biking column search and the shooting column search.

Instead of dynamically building an sql to update data based on certain fields that are filled in, I would like to try and do it via a stored procedure I have three fields passing potentially passing to a stored procedure
myCommand.Parameters.AddWithValue("@Field1",
Field1.Text)
myCommand.Parameters.AddWithValue("@Field2",
Field2.Text)
myCommand.Parameters.AddWithValue("@Field3",
Field3.Text)
Stored Procedure accepts 3 parameters
@field1 nvarchar(20), @field2 nvarchar(20), @field3 nvarchar(20)
I want to be able to pass parameters in a variety of ways
field1, field2, field3
or
field1, field3
or
field2, field3
When I attempt thsi, it provides an error of a missing parameter when I do not supply all three. Is there any way to pass exclude parameters at times. The most important thing is that I do not want to update the field to a null when a parameter is not passed, I want it to exclude updating that field altogether
I have a loop in JS, and I want to pass each parameter in that loop to a function in ASP.NET in the codebehind.
something like that:

And I want to pass a function in <%%> the elements[i].
How can I do that?

View 10 RepliesI want to query an SQL table using some Web controls to provide the parameters for filtering the records in the table. Results are displayed in a GridView.
I have a TextBox with an ID of "keyword" where the user may enter one or more keywords. I'd like to search 2 columns for instances of these keywords.
I also have a DropDownList named "category" that lists categories contained in a "category" column of the table.
I have a dataset with a TableAdapter for the table I want to search. Got it working fine with the DropDown List but not sure how to proceed with the TextBox and keywords.
What SQL query should I use? The user may not enter anything into the textbox, they may enter one word, or multiple words.
This is where I am now:
SELECT * FROM tablename WHERE category = @category AND ??
how to pass the in out parameters in stored procedures

I have an asp.net site which includes a "search" page that queries an SQL table, then redirects the user to a "results" page where the results of the query are displayed. The parameters for the query are assembled into a string which is the SELECT statement. I've been asked to add additional functionality that requires a secondary search which takes place on the "results" page. How can I pass the parameters from the "search" page to the "results" page so that I can access those parameters in the code behind? Here's the first page code behind (I inherited most of this from another developer):
