Hello Everybody,

SQL Command is : Select S_no as S. No. From Emp;

If you can think then I Can.

the alias name should be a valid identifier, no punctuation, no spaces,...

Select S_no as [S. No.] From Emp;

would work but as Luc said that its not best practice.

You're real problem is that you are putting UI information into the query, this type of formatting belongs in your user interface no the database

Oh and this does work in sql server 2005/08

SELECT ship [S. No.] FROM Ship AS S

Try adding quotation marks around the alias:

Select S_no AS "S. No." From Emp;

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. For more detailed information I think you should read through this: http://technet.microsoft.com/en-us/library/ms151870.aspx[^]

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.

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. Smile | :)
