In SQL query '.' can be used to get a column from a table...
For eg : "Select Employee.EmpId from Employee"
So Sql always expects a column name after a '.' , use some other characters as alias names.
This would solve your problem

Use a valid identifier. Dot is not a valid identifier.

Let's say I have a publisher and subscriber database set up. If I want to say, add a column to a table in publisher, will the change automatically be replicated to the subscriber database? Or is that only for data?

Modifications to the structure can also be replicated from publisher to subscribers but with several limitations. In short you can make 'minor' changes to the tables in publisher database and if those tables are included in a publication, modifications are repeated at subscribers.

Hi there,
I'm trying to create a database programmatically using .Net3.5 and C#. I have this nice SQL-script which works fine in the SSMS editor, but now to try it for real in C#. I learned that the GO-statements were only for the SSMS editor, so I removed those. (am I right on that one?). What am I missing here?
Context: MSSQL 2008R2, VS2008, .Net3.5, WindowsXP.
Below is my script. The error I get is the following:
Incorrect syntax near 'LOG'.\r\nDatabase 'dbName' does not exist. Make sure that the name is entered correctly.
The source I use to execute this script is here. (removed the try/catch/finally blocks etc)
SqlConnection conn = new SqlConnection(connectionString);
conn.Open();
string initDBQuery = string.Format(InstallationHelper.CreateDBScript(), settings.DatabaseLocation, settings.Database, settings.DatabaseUser, settings.DatabasePassword);
SqlCommand command = new SqlCommand(initDBQuery, conn);
command.ExecuteNonQuery();
This is the script (in C#-form):
string script =
@"
CREATE DATABASE [{1}] ON PRIMARY ( NAME = N'{1}', FILENAME = N'{0}\{1}.mdf' , SIZE = 3072KB , FILEGROWTH = 1024KB );
LOG ON ( NAME = N'{1}_log', FILENAME = N'{0}\{1}_log.ldf' , SIZE = 1024KB , FILEGROWTH = 10%);
ALTER DATABASE [{1}] SET COMPATIBILITY_LEVEL = 100;
ALTER DATABASE [{1}] SET ANSI_NULL_DEFAULT OFF ;
ALTER DATABASE [{1}] SET ANSI_NULLS OFF ;
ALTER DATABASE [{1}] SET ANSI_PADDING OFF ;
ALTER DATABASE [{1}] SET ANSI_WARNINGS OFF ;
ALTER DATABASE [{1}] SET ARITHABORT OFF ;
ALTER DATABASE [{1}] SET AUTO_CLOSE OFF ;
ALTER DATABASE [{1}] SET AUTO_CREATE_STATISTICS ON ;
ALTER DATABASE [{1}] SET AUTO_SHRINK OFF ;
ALTER DATABASE [{1}] SET AUTO_UPDATE_STATISTICS ON ;
ALTER DATABASE [{1}] SET CURSOR_CLOSE_ON_COMMIT OFF ;
ALTER DATABASE [{1}] SET CURSOR_DEFAULT GLOBAL ;
ALTER DATABASE [{1}] SET CONCAT_NULL_YIELDS_NULL OFF ;
ALTER DATABASE [{1}] SET NUMERIC_ROUNDABORT OFF ;
ALTER DATABASE [{1}] SET QUOTED_IDENTIFIER OFF ;
ALTER DATABASE [{1}] SET RECURSIVE_TRIGGERS OFF ;
ALTER DATABASE [{1}] SET DISABLE_BROKER ;
ALTER DATABASE [{1}] SET AUTO_UPDATE_STATISTICS_ASYNC OFF ;
ALTER DATABASE [{1}] SET DATE_CORRELATION_OPTIMIZATION OFF ;
ALTER DATABASE [{1}] SET PARAMETERIZATION SIMPLE ;
ALTER DATABASE [{1}] SET READ_WRITE ;
ALTER DATABASE [{1}] SET RECOVERY SIMPLE ;
ALTER DATABASE [{1}] SET MULTI_USER ;
ALTER DATABASE [{1}] SET PAGE_VERIFY CHECKSUM ;
USE [{1}];
IF NOT EXISTS (SELECT name FROM sys.filegroups WHERE is_default=1 AND name = N'PRIMARY') ALTER DATABASE [{1}] MODIFY FILEGROUP [PRIMARY] DEFAULT;
";

Yap, that's correct.

The semicolon is used to end a statement so in your database creation statement the LOG portion is part of the CREATE DATABASE statement. Try removing the extra semicolon from the first row:
CREATE DATABASE [{1}] ON PRIMARY ( NAME = N'{1}', FILENAME = N'{0}\{1}.mdf' , SIZE = 3072KB , FILEGROWTH = 1024KB )
LOG ON ( NAME = N'{1}_log', FILENAME = N'{0}\{1}_log.ldf' , SIZE = 1024KB , FILEGROWTH = 10%);
Haven't tried to execute a script using SqlCommand but hopefully it'll work. If it doesn't, you should split the statements to separate executions. Just a thought: From error-handling point of view it could better to use separate executions.

Yeah, what he said, plus I don't think the USE statement will work.

A while back I was trying to do the same, and several helpful souls told me it can't be done. Well, that just gets my dander up, so I went ahead and did it:
private void btnCreateDatabase_Click(object sender, EventArgs e)
{
String str;
SqlConnection myConn = new SqlConnection
("Server=BAAL\\SQLEXPRESS2;Integrated security=SSPI ;database=master");
str = "CREATE DATABASE MyDatabase";
SqlCommand myCommand = new SqlCommand(str, myConn);
try
{
myConn.Open();
myCommand.ExecuteNonQuery();
MessageBox.Show("Database Created Successfully", "MyApp",
MessageBoxButtons.OK, MessageBoxIcon.Information);
}
catch (System.Exception ex)
{
MessageBox.Show(ex.ToString(), "MyApp", MessageBoxButtons.OK,
MessageBoxIcon.Information);
}
finally
{
if (myConn.State == ConnectionState.Open)
{
myConn.Close();
}
}
}
I ran it once, then switched over to the server to check - sure enough, myDatabease was there, ready to be populated.
Your app will certainly need more, but it works, and should get you started.

Hi,
I'm designing an audit trail database to log user's activities. Should I create a single table to log all user activities e.g:
Id(PK) | UserId(FK) | ActionTime | ActionTaken
or, multiple tables; each per user e.g:
Table Name : AuditTrail_UserId
Id(PK) | ActionTime | ActionTaken
I'd like to be able to do 2 kind of text search though,
1. Search single user activities
2. Search all user activities
|
|
|
|
|
Just create one single table.
If you create a table per user the database will be unmaintainable.

Single table
This will do for now

Separating the tables per-user is not necessary. Make sure that you specify that the user ID is an index and the RDBMS will do all of the heavy work for you - making sure that internally the table is structures in such a way that queries such as:
select * from audit where UserID = 'someuserid'
are very rapid. It would be well worth examining the documentation on CREATE INDEX:
http://msdn.microsoft.com/en-us/library/ms188783.aspx[^]
Careful usage of features such as these will give a much more performant solution that trying to roll your own equivalent (by separating into tables per user).

I don't see any reason to put them in separate tables. If it's the same data, with only a single different property, then it should go in the same table and the extra property becomes part of the key.

I'm upgrading a MSDE SP4 Database consists of Tables containing Blob objects to SQL 2008 Express R2, during upgrade it goes on fine,and works after upgrade, but and after a while i get this microsoft error report.
Some unexpeceted errors have happened on the software you recently used.You were not asked to send the error reports at the time they occured.

Any clue ?

Wow, not even sure how to word the question... Here goes:
Basically, I'm trying to build a custom burn-down with TFS, Excel and SQL. Don't ask me why I'm doing a custom one when I shouldn't be, that's a question for my boss 
Anyhow, I have a query that's set up a few tables and now I want to join them. Here's an example of my two temp tables:
Tickets:
ID Changed date Points State
61 2011-02-25 06:38:07.090 0 For Production
61 2011-02-26 03:46:02.577 0 In Production
61 2011-03-04 03:22:32.620 0 Done
499 2011-03-04 04:26:10.060 0 New
623 2011-02-28 00:25:45.250 0.5 In Production
708 2011-03-03 00:55:31.407 3 In Development
708 2011-03-03 00:57:27.497 3 In Development
708 2011-03-03 03:55:17.390 3 In QA/UAT
708 2011-03-03 23:05:56.020 3 In QA/UAT
708 2011-03-04 05:21:43.133 3 In QA/UAT
738 2011-02-28 05:04:04.250 5 In Development
738 2011-02-28 22:56:58.053 5 In Development
738 2011-03-01 00:50:28.037 5 In Development
738 2011-03-01 21:06:35.550 5 In Development
738 2011-03-03 22:54:17.137 5 In QA/UAT
894 2011-02-28 00:29:04.183 0 To Do
Historical data in TFS is stored as a copy of the WorkItem row as it was BEFORE the change, along with a Changed Date field. In other words, the work item with id 3 has multiple copies in the WorkItemsWere table, each with a set of different properties, as can be seen above.
and Sprint Days:
Day Day of year
Mon 1 51
Tue 1 52
Wed 1 53
Thu 1 54
Fri 1 55
Mon 2 58
Tue 2 59
Wed 2 60
Thu 2 61
Fri 2 62
I am achieving my burn-down by joining these two tables. My results so far look like this:
Day Points Day of year
Mon 1 0 51
Tue 1 0 52
Wed 1 0 53
Thu 1 0 54
Fri 1 0 55
Mon 2 0 58
Tue 2 0 59
Tue 2 5 59
Wed 2 0 60
Wed 2 10 60
Thu 2 0 61
Thu 2 10 61
Fri 2 0 62
Fri 2 3 62
Fri 2 15 62
See, the problem is I am joining each row in my sprint days table against EVERY work item row with a changed date <= the sprint day, and then summing. Here's my query:
SELECT
[Day] AS [Sprint Day],
SUM(Points) AS Points,
[Day of year] AS [Order]
FROM
#sprintDays d
LEFT JOIN
(
SELECT
Id,
Points,
DATEPART(DAYOFYEAR, [Changed Date]) AS [Changed Date],
ROW_NUMBER() OVER
(
PARTITION BY
Id,
DATEPART(DAYOFYEAR, [Changed Date])
ORDER BY
DATEPART(DAYOFYEAR, [Changed Date]) DESC
) AS Row
FROM
#tickets
WHERE
([State] = 'Committed' OR
[State] = 'In Development' OR
[State] = 'In QA/UAT')
UNION
SELECT -- this is to ensure that something
0, -- comes out for any given day
0,
0,
1
) AS t
ON d.[Day of year] <= t.[Changed Date] -- this is the dodgy bit here, methinks
GROUP BY
t.Row,
t.Id,
[Day],
[Day of year]
HAVING
Row = 1
ORDER BY
[Order] ASC
What I REALLY need to do, is join against something like MAX(ChangedDate) WHERE ChangedDate <= SprintDay, i.e. the sum of the points of each row in #tickets that has both the highest (latest) ChangedDate and also has a ChangedDate that is smaller than the [Day of year] of the SprintDay row I am joining to.
Does that make any sense? Apologies if it doesn't, my brain is melting ever-so-slightly...

Hi,
First I must admit that I didn't follow the whole sequence, but if I understood correctly, you want to have each sprint date and the for every sprint date the sum of points for that and earlier dates. If that's correct, could you simply use scalar in your select list to calculate a running total. Something like:
SELECT d.Day,
d.[Day Of Year],
(SELECT SUM(Points)
FROM #tickets t
WHERE t.[Changed Date] <= d.[Day Of Year]
...other possible restrictions...) AS Points
FROM #sprintDays d

Aha! That's the rub, see - not just the sum of points for all earlier dates, but the one, latest date found per individual id in a list of earlier dates... I will give your suggestion a go and see if I can tweak it to my needs.
Thanks for your help! If you have any more suggestions, throw them my way It's really hard to explain, I think
EDIT:
At the moment it feels like I need to partition again, but I need to partition on the [Changed Date] of the sprintDays table on "each loop" of the select in order to find the highest ranked item... Maybe I should use a FOR loop or something? I want to avoid it, though, surely there's a way to do this in "Plain Old SQL".
