仅使用脚本在MS SQL Server之间移动多个表

Question

How can I move multiple tables between SQL servers (but not every table of the database)?

I have a list of the tables that need to be copied. Is there any way to create an enum (or something like that) from this list, and loop through the items, to create a dynamic script?

I already created a Linked Server connection, the script should work with this method. Identity insert also need to be used in the script.

What is the easiest way to do this?

You only should take care of the @dest and @tables.

declare @tables varchar(MAX)
declare @t varchar(50)
declare @sql varchar(MAX)
declare @dest varchar(80)

set @dest = 'myNewServer.newDb..';
set @tables = '[Table1], [Table2]'


while len(@tables) > 0
begin
  --print left(@tables, charindex(',', @tables+',')-1)
  set @t = left(@tables, charindex(',', @tables+',')-1)
  set @sql = 'select * into "+ @dest + @t + ' from '+@t
  set @tables = stuff(@tables, 1, charindex(',', @tables+','), '')

  execute(@sql)

end

This methods copies all the tabes data, preserving IDs because:

"... this doesn't copy any of the metadata other than the column information (names & datatypes). So it will not have security permissions, indexes, triggers, constraints. etc. That said the Management Studio example above also has the same problem." from https://msdn.microsoft.com/en-us/library/aa337553.aspx
