SQL server批量删除包含某字符的数据库

由于还原数据库太多了，想批量删除数据库，下面删除是包含abc数据库分享下：

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 sys.databases where name like '%abc%'
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
