Last value by what criteria?

Not sure why you need this bug:
SELECT TOP 1 X
FROM TABLE
ORDER BY X DESC

One of the fundamental principles of a relational database is that the physical order of rows and columns in the tuples (tables) is not important.
http://en.wikipedia.org/wiki/Relational_database[^]
If you need to extract data in a particular order, the data itself should provide the means of doing this. For instance, if you had an numeric EmployeeID field which was incremented every time a new employee joined the company then you could find the last value in your table by selecting the row of data with the highest EmployeeID value. You don't have any data items that you can use for this purpose in your table so you can't achieve this.

Assuming that both the columns are of the same data type
update yourtable set columnA = columnB, columnB = columnA

thanks for ur reply..its working but logically how it happens in sqlserver..by using a=b or b=a ..it will not give the same values in the both the columns...

Enough with the textspeak please. It's really annoying.
If you want to get the year/month description, concatenate the result of datename(month,month(start_date)) and year(start_date).

select DATENAME(month, start_date) from <tablename>

hi,
I am using MySql .NET Connector 5.1.2.
Following is the code I am using to read a longblob field from a table..
string selCmd = "SELECT * FROM document";<br />
MySqlCommand allDocsCmd = new MySqlCommand(selCmd, con);<br />
MySqlDataReader reader = allDocsCmd.ExecuteReader();<br />
reader.Close();
The execution hangs at reader.Close();
When I selected everything else but the blob field from the table and it worked fine i.e.
"select id,data from document" hangs but
"select id from document" works ok.
('data' is a LONGBLOB field in document table)
I am searching a cause and fix but lemme know if anyone has ne idea why this is happening..
Thanx.

hi!1
Actually i am a beginner with asp.net and databases .
i want to know that how can i access values from a table where some column name has null value say parentId ..
Mrinal

what if one value is int type and the other is null type
Mrinal

SqlDataReader r =//..some code..
int ParentId;
//short form
r.IsDBNull(r.GetOrdinal("ParentId"))?-1:Convert.ToInt32(r["ParentId"]);
OR
int ParentId = -1;
if (!r.IsDbNull(r.GetOrdinal("ParentId")))
{
ParentId = Convert.ToInt32(r["ParentId"]);
}

SELECT AField FROM ATable WHERE parentId is null

Hi,
I have a simple doubt.The maximum number of parameters in a stored procedure is 2100.
Like what is the maximum number of stored procedure in a MSSQL database ????
Be very grateful for any advice.

All I ever wanted is what others have....

I find that would be hard to reach that number.
Have you looked around google for your question about the max. number of stored procs?

SELECT distinct(P.firstname + ' ' + P.middlename + ' ' + P.lastname) AS UserName ,P.Id as UserId,G.Id,G.Fkgroupid FROM c_Groupmember G,c_Person P where P.Id=G.FKUserid and G.FKgroupId=" + Id + " and P.Status=0 order by P.firstName asc
it will disply the username if first name and lastname is there .if there is only firstname .then i won't display any value?....
what is the solution for this ?.in query itself i need to get all the usernames.

Rewrite query as
SELECT distinct( COALESEC(P.firstname,P.firstname,'') + ' ' + COALESEC(P.middlename,P.middlename,'') + ' ' + COALESEC(P.lastname,P.lastname,'')) AS UserName ,P.Id as UserId,G.Id,G.Fkgroupid FROM c_Groupmember G,c_Person P where P.Id=G.FKUserid and G.FKgroupId=" + Id + " and P.Status=0 order by P.firstName asc
for more information see COALESCE function documentation.

it is showing an error
Msg 195, Level 15, State 10, Line 1
'COALESEC' is not a recognized built-in function name.

ya.i got .it is 'COALESCE'. Not 'COALESEC'

Better way of working on queries will be putting them up in a stored proc, to avoid sql injection attacks.[^]
