do i need a terminator(or something else) between dynamic sql statements

working with Oracle Linked server in SSMS 2008R2

do i need a terminator(or something else)  between  OPENQUERY/dynamic sql statements

I have this line of code

TRUNCATE TABLE [dbo].[XREF_HEADER_DETAIL_ORACLE_EXTRACT_2019_STAGING]
begin try

DECLARE @StartDate AS VARCHAR(10) = '07-JAN-19';
DECLARE @EndDate AS VARCHAR(10) = convert(varchar, getdate(), 101);
DECLARE @Statement NVARCHAR(MAX) = N'
    SELECT *
    FROM OPENQUERY(
        XREF_PROD,
        ''SELECT


etcx......  code


EXECUTE sys.sp_executesql @Statement;



end try
BEGIN CATCH  
   select
   ERROR_NUMBER() AS ErrorNumber,
		ERROR_STATE() AS ErrorState,
		ERROR_SEVERITY() AS ErrorSeverity,
		ERROR_PROCEDURE() AS ErrorProcedure,
		ERROR_LINE() AS ErrorLine,
		ERROR_MESSAGE() AS ErrorMessage;
END CATCH



--- do i need additional code here between statements/dynamic sql statements  ?

--- next dynamic sql statement  

TRUNCATE TABLE [dbo].[ORACLE_CUST]


    SELECT *
    FROM OPENQUERY(
        XREF_PROD,
        ''SELECT reportsTor,
