DataSource Controls :: How To Bring The Result Without Using Cursor
May 13, 2010
Tag TableName FieldNameabc wc s_namelbl wc s_deslb2 wc s_prodin above fieldname(s_name,s_des,s_prod) column represent field in wc table.How can i bring this result. is this possible without using cursor. i was struggling past two days. i cant able to bring result for above.
i have problem white Object datasource. i have a multi-tier Application that include common layer ,DAL Layer,business logic and persantation layerwhen i add a object datasource to my page, it bring me only common layer classes . but i want use bisuiness layer classes what do i do ?
Running a select * from my table give me data like this:
Field1 Field2 Field3 Field4 Field5 Field6
NULL NULL NULL J 4GG4K C46D
DRIVE 0155 1 NULL W6665 NULL (C46D)
TEST 01444 5 NULL W4434 NULL (C46D)
NULL NULL NULL 1 WGG4K AAVE
HOME 01444 3 NULL 5HTYL NULL (AAVE)
NEW 09888 9 NULL 8HTTTE NULL (AAVE)
The problem is Field6 for the rows that are bolded. I need Field6 to repeat for each row until the next non null value is found in Field6, than I need that value to repeat again. I placed in parenthesis outside the NULL for Field6 what I need to show which is the value of Field6 above the records which Field6 is null.
I know this is confusing, but it's actually pretty simple to understand. I just need to get the first NON NULL value of Field6 and UPDATE the records below it where Field6 IS NULL to that value, then when it reached the next bolded row there is a new value for Field6, I then need to get that value and UPDATE the records below it which are null with the value.
I have a stored procedure that uses a cursor and also uses another stored procedure to return a column from the returned records.
[Code]....
See that part with 'exec dirinfo.dbo.d_searchempybyname @TicketEmail'? It works and returns the records but what I really need is to return a COLUMN from the record and store that column value in a variable which I can use - for example 'PRINT @VariableName'.
I have a requirement where I need to declare a Sql Statement dynamically in a cusror. When I declare dynamic Sql Statement and execute the SP, it throws an error message. The Cursor is not recognizing the dynamic Sql command.
As per the requirement, the sql statement will change according to the input parameter and it can't be declared as a static sql as shown below. Can anyone tell me, how this can be achieved any other alternative to do?
I have created the stored procedure in SQL server 2005. i have used nested cusrsors in this SP. also many records are there. So, its performance is too low.
i forced to use cursor, because the this is calcualtion process. i have to fetch the records one by one, do the calculation and insert the result to the another relevent tables.
So it cause big performance issue.this is my sample scanario.
First i have to take the products from the customerforecast for the certain duration. (i used cursor to fetch the products)
then i need to get the list of machines can run for the each product. (i used cursor to fetch the machines)
then i have to fetch the Unit per hour value for the combination of machine and prduct.then i have to use formula and do the calculation and store the result to the 3 different tables.
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 )
how can i find the total null values in a table without using sql cursor .
i want to find the percentage of the data which is avaibale in the table and how much percentage of data is unavailable ( or null). to make a comparision chart.
i have 6000 rows and 200 columns in a table , if i use sql cursor , it is taking too much time to execute ( 6000 * 200 ) loops. is there any inbuilt-function in sql to do it .?
How can I do this? I want to display result even if one value is just present. I've tried messing with the logical operators but still can't get it. Here is my SelectCommand.
I have the following code which writes to a Gridview:

Using the same methods of connecting to the database, how can I amend this code to write the result of a second query (which only returns a number) to a label?
I have one sproc with Dynamic Temp Table. Sproc returns dynamic temp table rows and when I drag and drop the sporc on to Linq to Sql Designer I am not getting Return Type as "(Auto-generated Type).
I'm creating a user control that enables users to search AD and add the selected names to a list (which is used to send mail lateron).
The problem is that the search results end up in the Listbox but all as the string "System.DirectoryServices.ResultPropertyValueCollection" in stead of the actual values.
I have a table that contains a date column along with others. I need to extract two sets of data from this table for two different time periods. Call them Current and Previous, so that I can compare them line for line. There are exactly the same number of days in both time periods.
The problem is that I need to return the data like this:
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person. Each student is identified by a unique ID.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;

However, when I try to access the results, with say dv.Table.Rows[0], I get the following error:

Upon debugging, there don't seem to be any results returned... when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
I am bulding a dvd catalog and have a table called DVD which holds all my details about each dvd except Genre, Director and Actor as I want more than 1 Genre, Director, Actor per DVD so put these in seperate tables to avoid repeating the data and used a joining tabe to join the tables so the tables I have are
DVD, Genre, Director, Actor, DVDGenre, DVDDirector and DVDActor
I have now written a stored procedure to pull the info about 1 DVD out of all the tables to display on the webpage I have now got the info I want out of the tables but as the data is now in 1 table I have repeating data is there a way to stop the data repeating the stored procedure i have written is
Just after some advice I have a stored procedure that returns several tables. I then need to loop through the tables and create dynamic gridviews using the data. At the moment this stored proc is called using

I have used an xsd file to populate everthing else, but due to this returning multiple tables i wasn't sure how this works should it just be in its own xsd? as all the oather i just get a datatable where as with this i need a dataset... how this makes sense...
Im using SQL Server 2005 and im using stored procedures. Is this possible? i need to get a number of results and do it in one SELECT statement or just one result set. Im using MS Chart Controls for reporting and they cant seem to process multiple result sets this is my problem, so basically to run a barchart i need to assign a column to the X axis and a column to the Y axis and it will then display my results.
My stored procedure below returns a result set with columns subpolicy_name, building_name, floor_name, room_name and total_savings. Im just wondering is it possible to split my total_savings column into 4 columns, for example subpolicy_savings, building_savings, floor_savings and room_savings, i need everything in a separate column. If you run this stored procedure you will see the result set.
i have a form that my i use to look up whether or not there is an email address in the database. i wrote a query with this basic structure:
select *
from table A, table B
where table A.email = "email" or table b = "email"
i though that would return all instances that the email occurred in either table. what i am getting back is a bunch of null or other unrelated records from table A with a matching email in table B. the thing is, these two tables primary key to join them. i thought i wouldnt need to do that though in this case.
here is the actually query i am using if it makes things more clear:
