Create table with dynamic table name.

Question

I'm trying to create a table
like
select x.*,  convert(nvarchar(20), getdate(), 101) AS LoadDate
into table1_20140512
from (
       select c1,c2,c3 from table2_20140512
       WHERE(LoadDate = (select MAX(LoadDate) FROM table2_20140512   )
       union all
    select c1,c2,c3 from table3_20140512
      WHERE(LoadDate = (select MAX(LoadDate) FROM table3_20140512  )
) X
I want to make table name dynamic, like 'table1'+toady's date
I declared three variables, but they didn't work as I expected  
These are my variables
DECLARE @table1 nvarchar(500)
DECLARE @table2 nvarchar(500)
DECLARE @table3 nvarchar(500)
SET @table1='H1_' +(CONVERT(VARCHAR(8),GETDATE(),112))
SET @table2='H2_' +(CONVERT(VARCHAR(8),GETDATE(),112))
SET @table2='H3_' +(CONVERT(VARCHAR(8),GETDATE(),112))

Answer 1

Try the following:
DECLARE @SQL nvarchar(2000);
DECLARE @table1 nvarchar(500) ='H1_' +(CONVERT(VARCHAR(8),GETDATE(),112));
DECLARE @table2 nvarchar(500) ='H2_' +(CONVERT(VARCHAR(8),GETDATE(),112));
DECLARE @table3 nvarchar(500) ='H3_' +(CONVERT(VARCHAR(8),GETDATE(),112));
PRINT @table1+' '+@table2+' '+@table3;
--H1_20140512 H2_20140512 H3_20140512
SET @SQL = 'select x.*, convert(nvarchar(20), getdate(), 101) AS LoadDate
into '+QUOTENAME(@table1)+'
from (
select c1,c2,c3 from table2_20140512
WHERE(LoadDate = (select MAX(LoadDate) FROM '+QUOTENAME(@table2)+' ))
union all
select c1,c2,c3 from table3_20140512
WHERE(LoadDate = (select MAX(LoadDate) FROM '+QUOTENAME(@table3)+' ))
) X '
PRINT @SQL; -- debugging
/* select x.*, convert(nvarchar(20), getdate(), 101) AS LoadDate
into [H1_20140512]
from (
select c1,c2,c3 from table2_20140512
WHERE(LoadDate = (select MAX(LoadDate) FROM [H2_20140512] ))
union all
select c1,c2,c3 from table3_20140512
WHERE(LoadDate = (select MAX(LoadDate) FROM [H3_20140512] ))
) X
EXEC sp_executeSQL @SQL;
