Rename SQL Server Schema

Question

How can I rename a schema using SQL Server?

Answer 1

This is a short version but works well.

declare @sql varchar(8000), @table varchar(1000), @oldschema varchar(1000), @newschema   varchar(1000)

  set @oldschema = 'old'
  set @newschema = 'dbo'

 while exists(select * from sys.tables where schema_name(schema_id) = @oldschema)

  begin
      select @table = name from sys.tables 
      where object_id in(select min(object_id) from sys.tables where  schema_name(schema_id)  = @oldschema)

    set @sql = 'alter schema [' + @newschema + '] transfer [' + @oldschema + '].[' + @table + ']'

   exec(@sql)
 end
