APEX & SQLWord integration explained

/0 Reacties/in /door

The SQLWord Apex demo application is based on Oracle HR-tables and demonstrates how to integrate SQLWord with Apex. In this post the implemention of a Job offer letter in an Apex page is explained. The MSWord template HR_Employee_Job_Offer.docx is the source document for this letter. We assume that you have compiled this template to stored procedure HR_EMPLOYEE_JOB_OFFER.
