How do I specify close existing connections in sql script

Question

I m doing active development on my schema in SQL Server 2008 and frequently want to rerun my drop create database script  When I run   USE  master  GO  IF  EXISTS  SELECT name FROM sys databases WHERE name   N MyDatabase   DROP DATABASE  MyDatabase  GO   I often get this error  Msg 3702  Level 16  State 4  Line 3 Cannot drop database  MyDatabase  because it is currently in use    If you right click on the database in the object explorer pane and select the Delete task from the context menu  there is a checkbox which to  close existing connections   Is there a way to specify this option in my script

Go to management studio and do everything you describe, only instead of clicking OK, click on Script. It will show the code it will run which you can then incorporate in your scripts.

In this case, you want:

ALTER DATABASE [MyDatabase] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO

try this C  code to drop your database   public static void DropDatabases string dataBase                     string sql     ALTER DATABASE      dataBase    SET SINGLE USER WITH ROLLBACK IMMEDIATE             using  System Data SqlClient SqlConnection connection   new System Data SqlClient SqlConnection ConfigurationManager ConnectionStrings  DBRestore   ConnectionString                         connection Open                using  System Data SqlClient SqlCommand command   new System Data SqlClient SqlCommand sql  connection                                 command CommandType   CommandType Text                  command CommandTimeout   7200                  command ExecuteNonQuery                              sql    DROP DATABASE     dataBase              using  System Data SqlClient SqlCommand command   new System Data SqlClient SqlCommand sql  connection                                 command CommandType   CommandType Text                  command CommandTimeout   7200                  command ExecuteNonQuery

According to the ALTER DATABASE SET documentation  there is still a possibility that after setting a database to SINGLE USER mode you won t be able to access that database      Before you set the database to SINGLE USER  verify the AUTO UPDATE STATISTICS ASYNC option is set to OFF  When set to ON  the background thread used to update statistics takes a connection against the database  and you will be unable to access the database in single-user mode    So  a complete script to drop the database with existing connections may look like this   DECLARE  dbId int DECLARE  isStatAsyncOn bit DECLARE  jobId int DECLARE  sqlString nvarchar 500   SELECT  dbId   database id          isStatAsyncOn   is auto update stats async on FROM sys databases WHERE name    db name   IF  isStatAsyncOn   1 BEGIN     ALTER DATABASE  db name  SET  AUTO UPDATE STATISTICS ASYNC OFF      -- kill running jobs     DECLARE jobsCursor CURSOR FOR     SELECT job id     FROM sys dm exec background job queue     WHERE database id    dbId      OPEN jobsCursor      FETCH NEXT FROM jobsCursor INTO  jobId     WHILE   FETCH STATUS   0     BEGIN         set  sqlString    KILL STATS JOB     STR  jobId          EXECUTE sp executesql  sqlString         FETCH NEXT FROM jobsCursor INTO  jobId     END      CLOSE jobsCursor     DEALLOCATE jobsCursor END  ALTER DATABASE  db name  SET  SINGLE USER WITH ROLLBACK IMMEDIATE  DROP DATABASE  db name

You can disconnect everyone and roll back their transactions with   alter database  MyDatbase  set single user with rollback immediate   After that  you can safely drop the database
