View 2 Repliesif there is no relation bettwenn two tables why do i need union for example like below Please
can u inform me
SELECT categoryId
FROM categories
UNION
SELECT shipperId
FROM shippers
i have two queries they are:
query1:
select CustID,NoOfChits from tblCust1 where [Group]='A' and CustID='a001'
query2:
select count(TKCustID) as Taken from tblAuctionGroup where [Group]='A' and TKCustID='a001'
Results of 1st query was:
----------
CustID NoOfChits
a001 2
Results of 2nd query was:
----------
Taken
4
But i want to like below:
--------------------------
CustID NoOfChits Taken
a001 2 4
in the above queries, 1st query displayed two columns and 2nd query displayed one column. but i would like to append the both results in single table or single record, i mean all results should be in same row in same result.
in my application i should make an union query thay union 15 tables
and this query begin with 150000 rows and will grow .
i need get just 10 rows from this query
i want make this query as best as possible
2 qustion
-----------------------------------------------------------1------------------------------------------
********View1*******
select id, lang, active from table1
union
select id,lang,active from table2
...--same way to all other 15 tables
*******SP***********
select top 10 from View1 where active=1 and lang='he' order by id desc
or
********View1*******
select id, lang, active from table1 where active=1 and lang='he'
union
select id,lang,active from table2 where active=1 and lang='he'
...--same way to all other 15 tables
*******SP***********
select top 10 from View1 order by id desc
---------------------------------------------2---------------------------------------
becauseof that this query is very complicate i want to know if i need take just 10 from each table
------------------------------------------------3--------------------------------------
if there is an idea how make this query better, i will glad to know.
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:
select lm.cemailaddr, lm.b1emailadd, b.emailaddr
SQL Select Union and total number of returned rows?
View 3 RepliesI have never work with a repeater and after a lot of research I got to the conclusion that this is the control I need to use for what I have to do. I need display data but I will need 2 headers and after some sort of amount of records the headers will repeat again. In this page you will find an example of what I'm trying to do http://ratings.fide.com/view_source.phtml?code=45276 I don't know if a repeater is the right control but i thin it is.

View 4 RepliesI am trying to sort a DataTable. If I declare a DataView and use the following approach it works perfectly:
Dim dt As DataTable = getData()
Dim dv2 As New DataView(dt)
dv2.Sort = "surname, name"
dt = dv2.ToTable
I wanted to do this without using a DataView though if possible to reduce the impact on resources. I tried the following approach but it doesn't work. I might be writing the code wrong so
Dim dt As DataTable = getData()
dt.DefaultView.Sort = "surname, name"
How do I sort a data table based on a particular column which has integer values in ascending order?
I wrote this:
leadtable.DefaultView.Sort = "Id"
But it doesnt seem to work, it displays fine but when i get try to get the values of the sorted datatable in an array they dont come in an sorted ordere Datatble is defined as:view plaincopy to clipboardprint?

I have a simple dynamic gridview with following code -
GV = new GridView();
i would like to sort a listview. i don't have a datasourceID. i bind the datasource manually. i think of using jquery(tablesorter) but i don't know how to use it.
View 1 RepliesI have encountered a problem about "order by" sorting in SQL. As some of the items (strings) in a dropdown list contain negative sign on the left, it is surprising for me that the SQL server cannot sort the items in an alphabetical order and as a result I was forced to set the property value (IsSort = False) of the Ajax ListSearch, which slow down the searching speed a lot. Below are examples of two of the string items with a negative sign on the left.
View 6 RepliesI have a listivew that is assigned a datasource in the code behind based on query string options. From what i have found out, once there is no datasource assigned in listview html then the sort feature stops working automatically and you must put the code in the _Sorting event. I cannot find a good example of this logic.
good example of the listview manual sort logic?
Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
I tried this:
Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:

Here is an example of just one of those SLQ statements inside GetSQLQuery:

I have table called "Logs". It has username, sitename, actiondate and lastupdate columns.
From this, I hve created tempLogs (Temp table) using condition where lastupdate >= somedate.
Once I get records in my temp table, I then want to retreive all the records again from "logs" table corresponding to same
username, sitename?
How would I do that.
BTW: Join will not work.
I have table in database with xml field and data like below

Suppose we have a website with 10,000 viewers each second. And we want to insert the viewer's information to the SQL database. So we must insert 10,000 records to the SQL each second. And it may take long time to do.
My question is: How can we decrease this process.
How can I find the 5 last records ?
CREATE PROC [dbo].[SP_NEWS_SELECT]
(
@NB_NEWS int,
@ID_NEWS int,
@DT_PUBLICATION datetime
)
AS
SELECT TOP @NB_NEWS *
FROM [REP_CLI].[S_ETATS].[T_NEWS]
ORDER BY [DT_PUBLICATION] ASC
This does not work
