para encontrar las columnas de la tabla use:
SELECT table_name=sysobjects.name,
column_name=syscolumns.name
FROM sysobjects
JOIN syscolumns ON sysobjects.id = syscolumns.id
JOIN systypes ON syscolumns.xtype=systypes.xtype
WHERE sysobjects.xtype='U'
ORDER BY sysobjects.name,syscolumns.colid
si desea datos en las tablas, use sql dinámico, puede hacer algo en estas líneas:
Declare @Sql varChar(100)
Declare @Temp Table (Ind INT, TableName nvarchar(100))
Insert Into @Temp
Select Row_Number() Over(Order BY [Name]), [Name]
FROM
(
Select [Name]
from sys.tables
) AS D
Declare @index int
Set @index = 1
while @index < (Select Count(*) From @Temp)
begin
SET @SQL = ' Select * From ' + (Select TableName From @Temp Where Ind = @index)
exec (@SQL)
Set @index = @index + 1
End
