I've seen this error occur when SQL Server is not running. Not sure that is your problem, but it is something to eliminate.

It could be exactly what it says. There is a configuration tool for SQL 2005 that will let you check this. Check the server protocols. There will be a short list something like this:

Shared Memory Enabled
Named Pipes Disabled
TCPIP Enabled
VIA Disabled

If you right-click on TCPIP and select properties you might be as surprised as me to find this:

IP1
Active Yes
Enabled No
Address 192.168.1.1
...

IP2
Active Yes
Enabled No
Address 127.0.0.1
...

Apparently SQL server comes with most things turned off. Try setting the Enabled(s) to yes and see if your problem changes. I was not using the TCPIP, so could not test it. Please post back if this made a difference.

Hey all,

Is there a way to know when table changed and who changed it?

is there a default table that logs those kinds of changes in MSSQL 2000?

Thanks
RoyRose.

Nope, unless you've enabled it. Article here talks about it.[^]

If it's just one table, then you can implement it yourself using triggers etc...
Googling for "sql server audit trigger" provides a load of methods.

1)In SQL Server:

select top 1 * from (select top 6 * from employee order by salary desc) as s order by salary asc

2)There are a few ways, but I like this one:

select * from (select count(*) as Duplicates, * from Employee group by name,salary) as tbl where Duplicates > 1

(but you have to have every field in the group by clause)

I had a Question I was hoping you might be able to help me with.

I am using VB.NET 2005 express and I have a list box that is bound to a table in a dataset. I want to be able to select one of the items in the list box and then use an item that corresponds to this item in the list box and I do not know how to do this.

For example, if I had a table named Person and this table had two fields one named PersonID (which is the key field), PersonName, and PersonAge. Say I had PersonName bound to the list box. So say I click on one of the PersonNames in the list box and then wanted to use the PersonAge, which corresponded to the name I had clicked, in a calculation. How would I access the PersonAge value?

I appreciate any help you could give me.

Thanks,

This is a very open question...

What type of database???

If you just need the connection string check our http://www.connectionstrings.com

Also do you want to perform inline SQL / Procedures or use the VS ADO database objects...

Not much help but not much to go on...

Hi, please help
I wanna select top 5 from table satisfying a condition
and at the same time count the number of rows returned based on selection.

Select top 5 LastName, (Select count (*) from TBL where lastname = 'Cruz') as Count from TBL where lastname = 'Cruz'

assuming there are only 3 rows with Cruz as latname
result should be:

Lastname | Count
Cruz 3
Cruz 3
Cruz 3

I mean my query doesn't work and have researched over the internet.

Please help. thank you. Cry | :((

If this isn't working, there is some other problem.

Can you be a bit more specific as to what error message you are getting. Maybe give us some samples of the data. According to what you have showed us here, there is absolutely NO reason your query should'nt return what you expect.

I mean my query doesn't produce the result I'm expecting.

For instance, I selected Top 5 with a given condition. But 3000 passed this condition. Rowcount should only be 5.

Upon querying such

Select top 5 LastName, <br />
(Select count (*) from TBL where lastname = 'Cruz') as Count <br />
from TBL where lastname = 'Cruz'

I figured it some 2 hours after my last reply.
I decided to create a temp table where I'd do my select top
then just count the number of rows in that temp table
with the whereclause, ofcourse

CREATE TABLE #RowCount(SubscriberId INT)

EXEC ('INSERT #RowCount' + ' SELECT TOP ' + @Top + ' (SubscriberId) FROM ' + @TableName)

--get total pages
EXEC ('SELECT (COUNT(*) - 1)/' + @SizeString + ' + 1 AS PageCount FROM #RowCount')

--get total number of rows
EXEC ('SELECT COUNT(*) FROM #RowCount')

so if i selected top 10000 and only 3000 passed the condition
totalrowcount is 3000; otherwise, if i selected top 2500 and 3000 passed the condition, totalrowcount is 2500

thanks! Suspicious | :suss:

Or you can try something like this:

SELECT
sub.surname,count(*) as count
FROM
(select top 5 surname from myTable) sub
GROUP BY sub.surname
--[WHERE surname = 'CRUZ']

OUTPUT will bev [without the where clause]
CRUZ 3
TOM 1
JACK 1

if you want to see all 5 rows [basically repeating ]

SELECT sub3.surname,sub2.count
FROM
(select count(*) as count from
(select top 5 surname from myTable where surname = 'CRUZ') sub) sub2
CROSS JOIN
(select top 5 column_name from myTable where surname = 'CRUZ' ) sub3

You can return it as an OUT parameter if you are using a stored procedure, or do a select query on the record after you've inserted it. AFAIK there's no easier way to get this.

When you insert into the table, use getdate() as the value for the DateCreated field:

insert into mytesttable (MyDateField) values (getdate())

Or, to make a default value of the current datetime, in design view in the Enterprise Manager type (getdate()) in the Formula field for the table.

Or, when you create the table in the Query Analyzer, do it this way:

CREATE TABLE [MyTestTable] (
    [IDColumn] [int] IDENTITY (1, 1) NOT NULL ,
    [DateCreated] AS (getdate())
) ON [PRIMARY]

Query Builder to make stored procedures?

eggsovereasy4-Oct-06 10:43

4-Oct-06 10:43

Ok, I know how to start the query designer in VS2005 and I can make a query and run it and see the data, thats all good.

I can also create new stored procedures by using the server explorer to go the SP folder, right click, add new. I then type in my stored procedure and everything works fine.

However, is there a way to create stored procedures with the query builder, other than using typed datasets?
