How to use batch separator inside Begin Try Catch SQL Server - sql

Question

I'm trying to create the SQL Script which needs to revert all the schema changes made if the error comes under any single SQL query. However, I'm trying to join both table and procedure under the same .sql file to run and try catch the error if present. It is working when i only uses the table, but when i try to add the procedure, it has some issue so added GO to separate table and procedure. But I can't able to Combine Begin try with GO statement.
BEGIN TRANSACTION
BEGIN TRY
Create TABLE [dbo].[Persons_1](
[PersonID] [int] NULL,
[LastName] [varchar](255) NULL,
[FirstName] [varchar](255) NULL,
[Address] [varchar](255) NULL,
[City] [varchar](255) NULL
) ON [PRIMARY] ;
Create TABLE [dbo].[Persons_2](
[PersonID] [int] NULL,
[LastName] [varchar](255) NULL,
[FirstName] [varchar](255) NULL,
[Address] [varchar](255) NULL,
[City] [varchar](255) NULL
) ON [PRIMARY] ;
CREATE PROCEDURE [dbo].[AAAtest]
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Select statements for procedure here
Select * from Persons_1 ;
END;
COMMIT
END TRY
BEGIN CATCH
ROLLBACK;
THROW; -- Only if you want reraise an exception (to determine the reason of the exception)
END CATCH

You don't need go statements in a batch. What you can do is use an exec statement. I added a drop table and drop proc so the program can be rerun as much as you want:
BEGIN TRANSACTION
BEGIN TRY
DROP TABLE IF EXISTS [dbo].[Persons_1] ;
Create TABLE [dbo].[Persons_1](
[PersonID] [int] NULL,
[LastName] [varchar](255) NULL,
[FirstName] [varchar](255) NULL,
[Address] [varchar](255) NULL,
[City] [varchar](255) NULL
) ON [PRIMARY] ;
DROP TABLE IF EXISTS DBO.PERSONS_2;
Create TABLE [dbo].[Persons_2](
[PersonID] [int] NULL,
[LastName] [varchar](255) NULL,
[FirstName] [varchar](255) NULL,
[Address] [varchar](255) NULL,
[City] [varchar](255) NULL
) ON [PRIMARY] ;
DROP PROC IF EXISTS DBO.AAATEST;
DECLARE #TSQL VARCHAR(4000);
SET #TSQL = '
CREATE PROCEDURE [dbo].[AAAtest]
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Select statements for procedure here
Select * from Persons_1 ;
END;'
EXEC (#TSQL);
COMMIT
END TRY
BEGIN CATCH
ROLLBACK;
THROW; -- Only if you want reraise an exception (to determine the reason of the exception)
END CATCH
