In Oracle the syntax would be something like

BEGIN
  EXECUTE IMMEDIATE 'CREATE TABLE CUSTOMER_'||v_company_id||' (..)';
END;

However this is probably a really bad idea. Six months down the line you'll want to add a column to the table and you'll need to work out which tables you need to add it to.

Also, stored procedures in Oracle need a fixed table name (of an existing table) or you'd have to reference everything through dynamic SQL which is a pain.

Better to have a single customer table with the company_id as an attribute. Then use Fine Grained Access Control to securely filter on the company_id to control who see's what company's data.
