Feb 19, 2011

I have a issue where I am trying to pull some records from an Access 2007 DB that has linked tables from a SQL 2005 Server. When I go to do this the browser IE8 just sits there and does nothing. THe little progress bar at the bottom moves about half way then that is it. It will sit there and show no errors or do anything. I have experience with connecting and manipulating Access and SQL server DB's but not through Access with linked tables from SQL Server. Here is test code below:
[Code]....
This does not produce an error or anything. The browser just sits there and sits there. Is there something I am missing?
There is likely an easy solution to this problem, but I'm stalling on it.Problem:Using EntityDatasource with a where="filed_id = @xxxx" the parameter is tied to a dropdownlist and works fine except I want to be able to select all records or basically no where condition. Is there a some way to do this without going to code behind?
I have a requirement that user can enter data into a table only once in two date and time ranges in a day as:
from 6 AM to 5:59 PM and from 6 PM to next day till 5:59 AM.
for Example:if today 25/ Nov/2010 at 9:45 AM i have entered a record then if i again try then can not enter the record in table till 5:59 PM but i can enter again today after 6:00 PM till 26/Nov/2010 - 5:59AM.
I have an SQL 2005 db with a table named "industry_suppliers."
I've created a query to enable someone to search this table using 3 parameters.
The results need to be grouped by "product_description" (which is essentially a category). When displayed on an .aspx page, for example, the results need to look like this:
Apples
Acme Apple Company Bradbury Orchards Oranges A1 Citrus Company Belfast Growers, Inc Bradbury Orchards
Notice how "Bradbury Orchards" is repeated under both categories. This is the result I want, EXCEPT in cases where someone wants to filter the search results by category. Let's say someone wants to search just for apple suppliers. The problem I'm having is that any record that appears under apples will also get listed again under any other categories associated with that record. So, searching for apple suppliers, the results are this:
Apples Acme Apple Company Bradbury Orchards Oranges Bradbury Orchards
I'm having trouble figuring out how to revise my query to avoid this problem.
I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.
The DoctorGen Table has primary key DocId and Doctors has Keys set on DocId and MemId. I want to get all records from DoctorGen where UserID = @UserId even if there are no matches in the Doctors Table. I'm not getting any records.
Id - Date - Type 1 - 2011-03-01 - 1 2 - 2011-03-02 - 0 3 - 2011-03-03 - 0 4 - 2011-03-04 - (-1) 5 - 2011-03-04 - 0
Can I somehow select the records between a record having type 1 and type -1 without using a cursor,for example the records with ids 1-4 in this example?
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 )
have a textbox to get the customer name , and i need to get the name from a dialog modal that have a grid that i can search from costumer table the line that i need... And can pass to my text box only the name of the costumer.
i have a query that select random records in access database in terms of time : "SELECT TOP 10 * FROM Tbl ORDER BY Rnd(-10000000*TimeValue(Now())*[ID])" now i wish to convert this query for using in sql server 2005 such that return random records in term of time
my have requirement is to select multiple records from Grid. by checking check box..
Actually i have 10 records in my Gridview i checked only 3 records by using check box . then i click NEXT button i need to show those 3 records only in another Gridview.
Using a ListBox, where multiple items can be selected. Using StringSplit SQL function the string passed from Listbox is separated where the delimeter is comma ( , ).ListBox is in search form where user enters search criteria using other controls and the ListBox. All works good by simply using below SQL statement in Stored procedure that carries search.
[Code]....
Question:- Now one of List Item is None , when None is selected or None is selected with other ListItems from ListBox it is required to retrieve all records where COLUMN IS NULL.Example: When the Male, Female and None is selected from ListBox, SQL statement in Stored procedure will be
[Code]....
Like to know how this can be handled? It is required to retrive NULL values when None is selected in ListBox as well as in combination of other ListItems(Male and Female) i.e., Male, Female, Null when user selects multiple items from ListBox.
