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).

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

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?

Hi,
i am using sql server 2005 and i am writing one query to concatename 3 column values..
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.
with regards
anu

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.[^]
|
|
|
|

Try SET CONCAT_NULL_YIELDS_NULL OFF before you begin the query. Works in 2000, not usre about 2005.

I posted this question before but I'm not sure it was fully understood:
I'm using MSSQL7, NT authentication and application roles so only my application can access the data. Also, other applications (like Excel) can not access the data and read it. So far, so good...
Yet, I noticed that if I try to access the SQL Server from another SQL Server on the network, it is allowed to see the list of tables, SP, etc. It is not allowed to open the table, but the Import/Export wizard is working and will allow retrieving data from the secured tables.
If I change to MSSQL authentication, any user will be able to access the data from my application and I don't want that either.
Unless I'm missing something, this is a big problem, especially today where any VPN connection with valid user name and password can actually log in to the domain and therefore connect to the database via SQL Server.
By the way, the server still must allow access to users via applications so logins must exist. I just don't want other SQL servers on the network to be able to connect to and import/export, view table and SP, etc.
Any ideas?

you're saying that if a user connects to your DB via the SQL Server tools, they have access to stuff that the role they log in under should not see ?

Correct...
It seems as if any user that can log in to SQL, can use SQL Server to see the list of table, list of SP and import/export data even though their user role does not allow SELECT, UPDATE, INSERT or EXECUTE.

Hi,
In a table with a primary key and a foreign key like this.
I-------I-------I-------I
I pkey I fkey I name I
I-------I-------I-------I
I 1 I 1 I ITEM I
I-------I-------I-------I
I 2 I 1 I ITEM2 I
I-------i-------I-------I
If we were to run a select query against this table that returns just one row. Would be any performance benefit if we have this select ?:
SELECT * FROM The_Table WHERE pkey=2 AND fkey=1
over when we have this select ?:
SELECT * FROM The_Table WHERE pkey=2
|
|
|
|
|
As the primary key is unique (a condition of being a primary key is that it uniquely identifies the row) then I wouldn't see any need for any additional information in the WHERE clause.
Whether it has any benefit or not depends on how you set up the table. If you go with the traditional defaults then I don't see it having any additional benefit. But I doubt it would have any negative effect either.
