In this code, will the print just display the contents of @cmd or will the @cmd be executed?

declare @table nvarchar(128)
declare @cmd nvarchar(500)
declare AllTables cursor for
select name from sys.tables
   where create_date >='2013-01-08'
open AllTables
fetch next from AllTables into @table
while @@fetch_status = 0
begin
  set @cmd = N'exec sp_rename ' + @table + ',' + 'XLElib.' + @table
  print @cmd
  fetch next from AllTables into @table
end

to execute you need

EXEC (@cmd)

for print
PRINT @cmd

instead of cursor why dont you try this

--CREATE SCHEMA TestSchema
--USE Test01
--GO

DECLARE @SQL VARCHAR(MAX)
DECLARE @Change VARCHAR(MAX)

set @Change = 'ALTER SCHEMA TestSchema TRANSFER dbo.['

SELECT
	 @SQL = COALESCE(@SQL + @Change + [name] + '] ', @Change + [name] + '] ')
FROM
	sys.tables
--WHERE
	--create_date = Your condition

PRINT @SQL

EXEC (@SQL)  

Open in new window

try this for schema change
DECLARE @SQL VARCHAR(MAX)
DECLARE @Change VARCHAR(MAX)

set @Change = 'ALTER SCHEMA TestSchema XLElib dbo.['

SELECT
	 @SQL = COALESCE(@SQL + @Change + [name] + ']; ', @Change + [name] + ']; ')
FROM
	sys.tables
WHERE
	create_date >= '2011-01-08'

PRINT @SQL

EXEC (@SQL)
