Hi,
I want to get a boolean variable from a stored procedure into .aspx page. Can you send me a piece of code for this?(C# will be better)
Best wishes,

You can write the code yourself but here is the idea.
Create a SqlConnection.
Create a SqlCommand, assing the connection to it and give it a command-text equal to your SPs name.
Set the CommandType of the command to StoredProcedure.
Add an output SqlParameter to the command, make it's name equal to the output param in your SP.
Execute the command
The parameter will then be assigned the value.
Use Convert.ToBoolean to get the value.

I run an application in my computer with the sqlserve installed in my computer too.
But when my code goes to :
SqlConnection conn = new SqlConnection("...");
conn.Open();
It's very strange that sometime it took so long to open the connection, about 4 seconds. But sometime it's fast, it took no more than 1s to finish.
I tried it many times. All the tests are done after restarting the computer, so the environment should be very clean.
Any one know why? Please kindly tell me.
Thanks in advance!

Post your connection string (hash the server ip, password and username first) so we can see if there is a problem in there.
Otherwise where is this SQL server you are connecting to in relation to the box running the code?

How is your computer resolving the location of the server? If your connection string uses the server name, it must be resolved to an IP address, which might take a bit of time if you are depending on netbios (windows workgroup) to get the job done. Will be worse if you have multiple newtork adapters...

The first time a connection is made to the server, it has to perform authentication, set up various parameters, and perform other initialisation.
When using connection pooling, a 'closed' connection (from the application's perspective) is not in fact closed. It's kept in the pool waiting to be reused. When you 'open' a connection and there's at least one spare connection in the pool, the provider simply resets the connection ("EXEC sp_reset_connection" in SQL Profiler trace output) and hands it out. This explains the sub-second connection time.
When there aren't any connections, but the pool can hold more (maximum not yet reached), it will have to do a proper connection in the same way as the first one. This will take about the same amount of time as the first did.

If you are referring to having the items both returned by the query in one record instead of two sets, you use a union.
select sum(total) as total1, null as total2
from table1
union
select null, sum(total)
from table2

Do you have access to the server utilities? or are you asking about how to do it programatically?

Hi !
In my application, I use a SQL command to create a table in an Access database (with ODBC).
I want ot have a text field, and I create it like this :
Name VARCHAR(128)
My problem is that in Access, this text field is set to : Empty String Not Allowed, but I want to allow empty string. How can I specify that in my SQL command ?
Thanks !

Hello!
You should be able to simply modify your CREATE statement to something that looks like this:
Name VARCHAR(128) NULL
to explicitly allow null strings. Then again, writing
Name VARCHAR(128) NOT NULL
will explicitly require NON-NULL strings.
I hope this helps.

Thanks for answering, but the problem remains. Your solution does allow to have a NULL string, but doesn't allow to have an empty string (which is not a null string !).
Any ideas ?

And you get some error message telling you this?
Someone correct me if I'm wrong, but I think that any attempt to store an empty string in a varchar type column will result in that column being set to NULL.

The thing is that in Access, there are two properties on a text field :
'NULL allowed'
and
'Empty string allowed'
But, with the SQL language, I don't know how to set these two properties.
This command :
CREATE T_Dummy (Label VARCHAR(30) NOT NULL);
Will change the first property (NULL allowed) but not the second one, which by default says 'no empty string allowed' and which is the one I'd like to change.
I couldn't find in the SQL language reference a way to change the second property and I wonder if it is something only Access understands.

You are probably hitting the nail on the head.  You'll have to dig through some Access specific programming reference books to likely find any mention of it. Good Luck

Allow zero length is an Access specific property and cannot be set with SQL.
Just one more reason not to use Access.

DECLARE @variableProc1 varchar(100)<br />
SET @variableProc1 = 'Val 1';<br />
EXECUTE('DECLARE @variableExec1 varchar(100); SET @variableExec1 = ''In variableExec1''; Print @variableExec1; ')<br />
--EXECUTE('DECLARE @variableExec2 varchar(100); SET @variableExec2 = ''In variableExec2'';')<br />
--SET @variableProc1 = variableExec2;<br />
PRINT @variableProc1;
Hi
In this example, I am able to print the value of @variableExec1, as long as I print it with EXECUTE context.
If I try assign the value of @variableExec2 to @variableProc1, it throws an error. Which I think because they are in different context.
My question is, how can I assign the value of @variableExec2 to @variableProc1 ?
Please advice. Thanks

You can't. The variable is declared only in the scope of the execute statement.

I have 4 databases named: db1, db2, db3, db4 on the same SQL Server. All 4 databases have the same table Department(ID, Name) but the data is different. For example:
Table ID Name
db1.Department 1 Dept1
db2.Department 1 Dept2
db3.Department 1 Dept3
db4.Department 1 Dept4
I use SQL Query analyzer to execute the code fragment below:
declare @n int
declare @Name nvarchar(256)
set @n = 1
while (@n < 5)
begin
if (@n = 1) use db1
else if (@n = 2) use db2
else if (@n = 3) use db3
else if (@n = 4) use db4
select [Name] from Department where [ID] = 1
set @Name = [Name] from dbo.Department where [ID] = 1
print @Name
set @n = @n + 1
end
The results:
---------------------------------
Dept1
Dept4
---------------------------------
Dept2
Dept4
---------------------------------
Dept3
Dept4
---------------------------------
Dept4
Dept4
But I think the correct result should be
---------------------------------
Dept1
Dept1
---------------------------------
Dept2
Dept2
---------------------------------
Dept3
Dept3
---------------------------------
Dept4
Dept4
The question is: Is there anything wrong from me or from SQL???

It sounds like your first conditional is falling through to the last case.
Have you tried running it with conditions you know will always be false?
It looks like it should work....

Below is my query. When I do a count it is counted all location,I want to be have a count after group by executes. How do I do this?
SELECT a.Number, a.Location,count(a.Location)'Number'
FROM Reports_Location
GROUP BY a.Number, a.Location
|
|
|
|
|
Not sure of the meaning. But if you are looking for a count of locations you could try this
select count(*) from (
select unique location from reports_location
)
;
