I have a form into which the visitor can enter data, and I want to store this data in a mysql database via the $_POST variable. What do I need to prevent sql injection?
Hello,
We have observed that there seems to be a maximum number of ids/variables which one can pass in the IN clause of SQL as comma seperated values. To avoid this we are storing all the ids in a table and doing a SELECT within the IN clause. This however means extra database operations to store and retrieve ids. Is there any other way to use IN without SELECT?

I use LINQ to SQL and i cant figure out which column is that!?
Tried numerous things but i get the same meaningless error i got from within Visual Studio.
Also I use .NET 3.5 SP1, but errors are still returned useless.
Hi,
I want to translate LINQ expression tree to SQL statement and I don't want to write my own code for this.
Example:
var query = from c in Customers
where c.Country == "UK" &&
c.City == "London"
select c);
To
SELECT ... FROM Customers AS c WHERE c.Country = "UK" AND c.City = "London"
I know DataContext.Log, but I want to use:
query.ToSqlStatementString()
Thanks

Hi,
I have a server where I installed SQL Server 2008 and after I applied the SP1.
Now, I want also to add the Analysis Services to this instance by using the "Add or remove features...".
My questions are:
Is it possible to add the Analysis Services on a server with SP1 already installed?
How can I apply the SP1 also to the new Analysis Service feature?
THANKS!
Hi guys:
Suppose we got a original query as follows:
SELECT A, B, C FROM tblA
Now, I need to additional artificial rows like
SELECT 'Kyala', B, C FROM tblA when, for example, C = 100 to be inserted into the resultset.
How could I achieve it using a single SQL instead of relying on table variable or temp table?

I have two SQL 2005 instances that reside on different networks. I need to backup a database from instance A and restore it to a database in instance B on a weekly basis so that both databases hold the same data. After the restore, logins SIDS on database B are changed and therefore users can't log into database B and connection strings for the web application it supports are broken. Is there a work around for this? Thanks.

What is a candidate row when talking about Oracle and SQL? Using it in a sentence would be as such:
"The candidate row is fetched from the table specified in the outer query."
