How to create a table and add columns to it with a stored procedure

Question

Hi,
I hope that someone can help me.
I want to create an empty table with the same columns as another
table but with 4 columns more.
So it's actualy a copy of a table but with 4 added columns.
I have to do it in a stored procedure but I don't know which
statements I have to use. I need to give 3 parameters : schema,
table and prefix(e.g. the pers from column pers_number)
Can someone help me?
Thanks in advance, Ann

Answer 1

you can !!
here is some examples
DECLARE
sql_stmt VARCHAR2(200);
plsql_block VARCHAR2(500);
emp_id NUMBER(4) := 7566;
salary NUMBER(7,2);
dept_id NUMBER(2) := 50;
dept_name VARCHAR2(14) := 'PERSONNEL';
location VARCHAR2(13) := 'DALLAS';
emp_rec emp%ROWTYPE;
BEGIN
EXECUTE IMMEDIATE 'CREATE TABLE bonus (id NUMBER, amt
NUMBER)';
sql_stmt := 'INSERT INTO dept VALUES (:1, :2, :3)';
EXECUTE IMMEDIATE sql_stmt USING dept_id, dept_name, location;
sql_stmt := 'SELECT * FROM emp WHERE empno = :id';
EXECUTE IMMEDIATE sql_stmt INTO emp_rec USING emp_id;
plsql_block := 'BEGIN emp_pkg.raise_salary(:id, :amt); END;';
EXECUTE IMMEDIATE plsql_block USING 7788, 500;
sql_stmt := 'UPDATE emp SET sal = 2000 WHERE empno = :1
RETURNING sal INTO :2';
EXECUTE IMMEDIATE sql_stmt USING emp_id RETURNING INTO salary;
EXECUTE IMMEDIATE 'DELETE FROM dept WHERE deptno = :num'
USING dept_id;
EXECUTE IMMEDIATE 'ALTER SESSION SET SQL_TRACE TRUE';
END;
