I have a table that contains image data type and has more than 20,000 records.I want to change its file group to the new file group. I tried to change it using table designer, but everytime I wanted to save it, it occured an error with this message:
[Code]....
Does anyone know how to change file group using Alter Table query? I'm using SQL Server 2005.
how do i write my alter schema query in Asp.net
using the sqlclient object..
I need to change a user's role in my application. Therefore I need to know the correct syntax in code behind to alter a user's role; i.e. string sql = "ALTER TABLE ...etc". I'm not sure how to implement this at all. Is it similar to the INSERT INTO query used in code behind, where we define the parameters etc?
View 2 RepliesI am using SQL SERVER 2008 database. I have a table Customers in which the CustomerID column is had datatype INT intially but due to increase in Customers the number range is exceeding which may cause error arithmetic overflow of data. Hence I thought to modify the datatype from INT to BIGINT and wrote an alter script but when I ran the script it failed. Hence provide me in creating alter script for the updating the datatype of the primarykey column for the Customers table.
View 2 Repliesi have the following objects:
Event:
- EventID (PK)
- GroupID (FK)
- StartDate
Group:
- GroupID (PK)
- GroupName
What i need to do is select the last 5 events for each group using LINQ to Objects. I tried starting with:
[Code]....
But i'm not sure how i only take the last 5 per group.
The simple way of doing this is to get the groups and then have a property on that which returns the last 5 events but if i databind this i will have to use a nested Repeater/ListView. Ideally i would like to have a row foreach event.
i have 2 tables company(companyId,companyName,City,state,country) and people(peopleId,peopleName,City,state,country) i want to display the total no of contacts and Total no of companies with respect to countries
i tried with group by: select country,count(*)companyId from company group by country is displaying the total number of companies with respect to country select country,count(*)peopleId from people group by country is displaying the total number of peoplewith respect to country
but i want to combine these two quries i want the output as :
Country Companies Contacts
India 10 5
USA 0 10 (usa is having only contacts ,i doesn' have the companies)
UK 8 0 (ukis having only companies ,i doesn' have the contacts)

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.
this is my sample script
[Code]....
after execute this script which returns a column name "XML_F52E2B61-18A1...." can I change this column name?like this
select EMPNO AS EmployeeName -- we can use AS to change column name
from EMPLOYEE
I'm using a linq group by query (with two grouping parameters) and would like to use the resulting data in a nested repeater.
var dateGroups = from row in data.AsEnumerable()
group row by new { StartDate = row["StartDate"], EndDate = row["EndDate"] };
"data" is a DataTable from an SqlDataAdapter-filled DataSet. "dateGroups" is used in the parent repeater, and I can access the group keys using Eval("key.StartDate") and Eval("key.EndDate").
Since dateGroups actually contains all the data rows grouped neatly by Start/End date, I'd like to access those rows to display the data in a child repeater. To what would I set the child repeater's DataSource? I have tried every expression in markup I could think of; I think the problem is that I'm trying to access an anonymous member (and I don't know how.) In case it doesn't turn out to be obvious, what would be the expression to access the elements in each iteration of the child repeater? Is there an expression that would let me set the DataSource in the markup, or will it have to be in the codebehind on some event in the parent repeater?

I have a button click event that adds a record to a table based on the userid and threadid the user is viewing. I am a bit new to entity so I am stumbling around. I have to where conditions
ThreadID == threadid

var query = context.TrackLists.First(t => t.ThreadID == threadid);
context.TrackLists.First(t => t.UserId == userIdPosts);
Sequence contains no elements

When I call select in codebehind, after 30sec it throws timeout expired SqlException:
[Code]....
again , this select took up to 3 sec to be executed. In application I tried to use SqlConnection and SqlTableAdapter instead of SqlDataSource, with the same query, and again it took up to 3 sec.
If I choose tighter interval (e.g '2011-01-20 00:00:00' - '2011-01-21 00:00:00') , there is no timeout exception, so I know that sqldatasource select is executed correctly. So the conclusion is that sql server is not using index while executing query sent from sqldatasource, but is using index whenever else. I have also checked the index statistics on sql server and it is like that. In profiler i can see slight difference between this two cases. As for SqlDataSource, in events table, in first column "EventClass" after 30 sec, there is this: "RPC:Completed" and application throws timeout. If i use SqlConnection and SqlTableAdapter then at the same place there is this: "SQL:BatchStarting" and "SQL:BatchCompleted" and application does not throws timeout(the index has been used).
what is so special on SqlDataSource connection, that Sql Server performs differently compared to other types of connections?
Im using two stored procedures to write and update values in a SQL DB. Im using the SQLDatasource update method. When I run the webpage on my development server everything runs fine. When I try and run the web page on my Live server I get the following error :System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This always takes 30 seconds to fail - and looking at google it seems that this is a connection timeout error.In my web.config file I have updated the connectionstring line to include a timeout setting :
connectionString="Data Source=myserver;Initial Catalog=ReportServer;Integrated Security=True;Connect
Timeout=10000"
But this hasn't helped at all.

View 4 RepliesI have tried to query a table with an xml column by using XQuery and I can't get the Select to work.
All my knowledge/understanding of the subject comes from this MSDN article:

so I am probably overlooking something minor:
I tried this query Select col1, Phone.Query('element CellPhone {I am not sure about what goes here} I tried {data('Phone/cellPhone} from aTable Where Phone.Exist('/Phone/cellPhone/text()[contains.,"412-8977"]') = 1 This syntax is definitely not fun.

View 3 RepliesI attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date.

So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.

how to get sql query output in text file?
View 1 RepliesI have an SQL table called tbl, im trying to add the columns A, B and C to it.
When i execute the command :
addcolumns = "ALTER TABLE SqlCreatedTbl ADD A char(50) ;";
cmd = new SqlCommand(addcolumns, conn);
conn.Open(); cmd.ExecuteNonQuery();
The column is added perfectly and i can see it in the table !
However, when i try to add multiple columns, it does NOT work, it gives me an error..
the command im writting for adding multiple columns is the following:
addcolumns = "ALTER TABLE SqlCreatedTbl ADD ( A char(50), B char(50), C char(50) );";
the debugger highlights the line : cmd.ExecuteNonQuery(); and throws the following exception: Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near '('.
