Creating a Stored Procedure with Multiple Nested Begins - sql

Question

How can place multiple "Begins" in a procedure to drop and create tables?
My attempt -
CREATE PROCEDURE procCreateCarTable
IS
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE CARS';
END;
COMMIT;
BEGIN
EXECUTE IMMEDIATE 'CREATE TABLE CARS (ID VARCHAR2(1), NAME VARCHAR2(10), TITLE VARCHAR2(10))';
COMMIT;
END;
END;
One by one the executes work but when creating this procedure I get the following error -
ORA-06550: line 5, column 1:
PLS-00103: Encountered the symbol "END"
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
Here is the SQL procedure that I got to work as mentioned in my comment below -
CREATE PROCEDURE procCreateCarTable
IS
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE CARS';
EXCEPTION WHEN OTHERS THEN NULL;
EXECUTE IMMEDIATE 'CREATE TABLE CARS (ID VARCHAR2(1), NAME VARCHAR2(10), TITLE
VARCHAR2(10))';
COMMIT;
END;
I added an EXCEPTION in case table CARS does not exist, but now my latest procedure below fails -
CREATE PROCEDURE procCreateCarTable
IS
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE CARS';
EXCEPTION WHEN OTHERS THEN NULL;
EXECUTE IMMEDIATE 'CREATE TABLE CARS (ID VARCHAR2(1), NAME VARCHAR2(10), TITLE
VARCHAR2(10))';
EXECUTE IMMEDIATE 'DROP TABLE TRUCKS';
EXCEPTION WHEN OTHERS THEN NULL;
EXECUTE IMMEDIATE 'CREATE TABLE TRUCKS (ID VARCHAR2(1), NAME VARCHAR2(10), TITLE
VARCHAR2(10))';
COMMIT;
END;
The only reason I could think of as to why my latest procedure failed is because of the other 'EXCEPTION'. I do want the other one there so the procedure can still create the TRUCKS table. Any suggestions?

Through trial and error I created the procedure:
CREATE PROCEDURE procCreateCarTable
IS
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE CARS';
EXCEPTION WHEN OTHERS THEN NULL;
EXECUTE IMMEDIATE 'CREATE TABLE CARS (ID VARCHAR2(1), NAME VARCHAR2(10), TITLE
VARCHAR2(10))';
END;
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE TRUCKS';
EXCEPTION WHEN OTHERS THEN NULL;
EXECUTE IMMEDIATE 'CREATE TABLE TRUCKS (ID VARCHAR2(1), NAME VARCHAR2(10), TITLE
VARCHAR2(10))';
END;
END;
