I know you can do bulk XML inserts into SQL Server 2005 tables from your C# code using datasets/datatables.
Is it possible to do the same but as a delete?
I know a little about SQL injections and URL decode, but can someone who's more of an expert than me on this matter take a look at the following string and tell me what exactly it's trying to do?
Some kid from Beijing a couple weeks ago tried a number of injections like the one below.
%27%20and%20char(124)%2Buser%2Bchar(124)=0%20and%20%27%27=%27
Is it possible to do something like this:
INSERT INTO table(col1, col2) VALUES(something_from_another_table, value);
With something_from_another_table being a SQL command? Like, is there something I can do that's equivelant to:
INSERT INTO table(col1, col2) VALUES((SELECT value FROM table2 WHERE id = 3), value);
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?
I have a question regarding the Sql Joins.
whenever we join two different tables on some fields.
what will happen exactly inside oracle which will result in the query output.

Hi. I'm trying to pivot some data in SQL Server 2000, but the user that runs the application only have read/write permissions. I've looked the solutions posted here, but all involving create/destroy temporary tables.

I'm working on a mock exam paper at the moment, however I have no set of correct answers and I'm not sure what the correct answer of this SQL query is.
Given a table:
foo, bar
a , 1
b , 3
a , 2
c , 1
and the query:
SELECT foo, sum(bar)
FROM table
GROUP BY foo
The two ways I can see this going are either:
a 3
a 3
b 3
c 1
or
a 3
b 3
c 1
Thanks.
How would one go about converting this into a UDF? I'll pass the product_id to the UDF.
Running SQL 2k5
SELECT
sum(qty) as qty,
product_id
FROM vProductQuantity
WHERE
product_id = @product_id
GROUP BY product_id
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
I have some doubt as follows
We are UPDATING a field in SQL and ALTER the row also.After giving the COMMIT command the system is crashed.Wat will happen to the commands given,whether it will UPDATE and ALTER the table r not?
I have a SQL table it has more than 1000000 rows, and I need to select with the query as you can see below:
SELECT DISTINCT TOP (200) COUNT(1) AS COUNT, KEYWORD
FROM QUERIES WITH(NOLOCK)
WHERE KEYWORD LIKE '%Something%'
GROUP BY KEYWORD ORDER BY 'COUNT' DESC
Could you please tell me how can I optimize it to speed up the execution process? Thank you for useful answers.
Hi,
I would like to select a random line in my database. I saw this solution on a website:
SELECT column FROM table
ORDER BY RAND()
LIMIT 1
This SQL query run but someone said me that it was a non performant query. Is there another solution ?
Thx
Is there any way showing the detailed exception for String or binary data would be truncated.
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.
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?

Does closing a java.sql.Connection also close all the statements, prepared statements, etc. obtained from that connection? Or is there going to be memory leak if I close the connection but leave the statements, etc. unclosed?
thanks for yout time helping on this ;)

How to find out the last date and timestamp of schema updation in SQL Server database. I could locate the database created and last back up date from properties. But, couldn't find the last schema updated date. Is there a way to find this out?
I was wondering if it's possible to do something like this (which doesn't work):
select cast( (exists(select * from theTable where theColumn like 'theValue%') as bit)
Seems like it should be doable, but lots of things that should work in SQL don't ;) I've seen workarounds for this (SELECT 1 where... Exists...) but it seems like I should be able to just cast the result of the exists function as a bit and be done with it.
