SQL Server 批量删除指定数据库

批量删除指定数据库。

比如我想要删除数据库名字中包含 “vivi”的所有数据库：

if object_id('tempdb..#dbToDelete') is not null 
    drop table #dbToDelete
if object_id('tempdb..#databaseName') is not null 
    drop table #databaseName
declare @dbToDelete table(name varchar(50))
declare @databaseName varchar(100)
--insert into @dbToDelete select name from Master..SysDatabases where name like '%vivi%'
insert into @dbToDelete select name from sys.databases where name like '%vivi%'
while exists(select name from @dbToDelete)
begin
 
    select top 1 @databaseName=name from @dbToDelete
 
    if exists(select * from sys.databases where name = @databaseName)
    begin
        print 'dropping databse: '+@databaseName

        --强制删除所有符合条件的实例
          exec('
        use master
        ALTER DATABASE ' + @databaseName +' SET SINGLE_USER WITH ROLLBACK IMMEDIATE
        drop database '+@databaseName)
        
    end
     
    delete from @dbToDelete where name = @databaseName
end
