please give solution of the test SP below :

create procedure TestSP(@ExistTable nvarchar(128),@NewTable nvarchar(128))
as
begin
select * into @NewTable from @ExistTable
end

Error shows
"Msg 102, Level 15, State 1, Procedure TestSP, Line 5
Incorrect syntax near '@NewTable'."

if I use
create procedure TestSP(@ExistTable nvarchar(128),@NewTable nvarchar(128))
as
begin
select * into [@NewTable] from [@ExistTable]
end

Then SP creates but not execute and the error shows:

exec TestSP ('test2','test1')

"Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'test2'."

In most SQL queries you can not use variables (the most common reason is age)...
What you have to do is create a dynamic SQL...
Something like this:

SQL

DECLARE @SQL AS NVARCHAR(MAX)
SET @SQL = "select * into " + @NewTable + " from " + @ExistTable
EXEC(@SQL)
