I want to query like this:
select * from table where concat(',', ServiceCodes, ',') like '%,33,%';
select * from table where (','||ServiceCodes||',') like '%,33,%';
so, I wrote this code:
ICriteria cri = NHibernateSessionReader.CreateCriteria(typeof(ConfigTemplateList));
cri.Add(Restrictions.Like(Projections.SqlFunction("concat", NHibernateUtil.String, Projections.Property("ServiceCodes")), "%,33,%"));
I get sql similar :
select * from table where (ServiceCodes) like '%,33,%';
But it is not what I want,how to do it???
thanks!
We have a requirement to log IP address information of all users who use a certain web application based on JEE 5. What would be an appropriate sql data type for storing IPv4 or IPv6 addressses in the following supported databases (h2, mysql, oracle). There is also a need to filter activity from certain IP addresses. Should I just treat the representation as a string field (say varchar(32) to hold ipv4, ipv6 addresses)

SQL server2005
I want to show top 100 but if there are not 100 only want to show those and not include zero counts in the result
SELECT TOP (100) UserName, FullName_Company, FullName,
(SELECT COUNT(*)
FROM dbo.Member_Ref
WHERE (RefFrom_UserName = dbo.view_Members.UserName) AND (RefDate >= '5/1/2010') AND (RefDate <= '6/1/2010'))
AS RefFromCount
FROM dbo.view_Members
WHERE (MemberStatus = N'Active')
ORDER BY RefFromCount DESC
I have tried using Group By and HAVING COUNT(*)0 all with the same wrong results
I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1}
Select command of appropriate SqlDataSource returns columns of type INT and BYTE (from SQL Server 2008).
So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant().
How to implement such conversion in page markup?
I am using SQL Server 2000. I have a database with n number of tables in it. I have configured a maintenance plan. If I enable integrity check and run the plan, I am not able to enter any data through VC++/ADO.

Hi,
Is there any way to cache LINQ to SQL queries by looking at the parameters that were previously passed and bypass the database all together?
I know L2S caches some database calls, but I'm looking for a permanant solution as in, even if the applciation restarts, that cache reloads and never asks the database again.
Are there any frameworks for C#?
I have the following SQL query which returns the correct results:
SELECT *
FROM `tags`
WHERE tag_name = '???\\\"?-???????'
If I change it to
SELECT *
FROM `tags`
WHERE tag_name LIKE '???\\\"?-???????'
or to
SELECT *
FROM `tags`
WHERE tag_name LIKE '???\\\"?-???????%'
It doesn't work. It will work if I remove all the backslashes and " from the query.

I created a Windows Forms Application to which I added a DataGridView and LINQ to SQL Classes from one of my databases. I can successfully bind one of my database's tables to my DataGridView:
var dataSource = from c in _db.NetworkedEquipments
select c;
dataGridView1.DataSource = dataSource;
However, the foreign keys get duplicated, that is, the columns appear twice. How can I prevent this?
I need to use C# to get data from database(sql) and the data in database is updated every few seconds. So do I have to make a loop or there is a better way to do that? Is it possible that when database is updating, the program can wait until it finishes updating? thx!

While there's lots to like about DataObjects.NET, I've found help resources to be a lean, and can't find a solit example of using DataObjects.NET with RDBMS generated primary keys. It would seem as though D4O won't do inserts against SQL Server unless it's in controll of the key.
Has anyone solved this in the wild?
