The Script

DECLARE
    v_workspace    VARCHAR2(255) := 'ORACLE'; -- Change to your workspace
    v_blob         BLOB;
    v_files        apex_t_export_files;
    v_filename     VARCHAR2(255);
    v_mimetype     VARCHAR2(255) := 'application/zip';
    v_workspace_id NUMBER;
BEGIN
    -- Set workspace security context
    v_workspace_id := apex_util.find_security_group_id(p_workspace => v_workspace);
    apex_util.set_security_group_id(p_security_group_id => v_workspace_id);

    -- Initialize ZIP file
    sys.dbms_lob.createtemporary(v_blob, TRUE);

    -- Export all applications from workspace
    FOR r IN (
        SELECT application_id, workspace_display_name
        FROM apex_applications
        WHERE UPPER(workspace) = UPPER(v_workspace)
    ) LOOP
        v_filename := r.workspace_display_name;
        v_files := apex_export.get_application(p_application_id => r.application_id);
        apex_zip.add_file(
            p_zipped_blob => v_blob, 
            p_file_name => 'f' || r.application_id || '.sql', 
            p_content => apex_util.clob_to_blob(v_files(1).contents)
        );
    END LOOP;

    -- Finalize and download ZIP
    apex_zip.finish(v_blob);
    apex_http.download(
        p_blob => v_blob, 
        p_content_type => v_mimetype, 
        p_filename => v_filename || '.zip'
    );
END;

How It Works

1. Security Context: Sets the workspace security context to access applications

2. Application Discovery: Queries all applications in the specified workspace

3. Export Loop: Exports each application and adds it to a ZIP file

4. Download: Triggers automatic download of the ZIP file containing all apps

Implementation Steps

1. Create a Button: Add a "Download Apps" button to your page

   • Set Action: "Redirect to Page in this Application" and redirect to the same page

   • Set Request: "DOWNLOAD_APPS"

     

2. Create Page Process: Add a "Before Header" process

   • Type: PL/SQL Code

   • Paste the script above

   • Server-side Condition: "Request" or "Request is contained in Value" = "DOWNLOAD_APPS"

     

3. Customize: Change the v_workspace variable to your workspace name

Benefits

• Batch Processing: Export all applications at once

• Automated Packaging: Creates a ready-to-download ZIP file

• Time Saving: No manual export for each application

• Backup Ready: Perfect for creating workspace backups

This script is ideal for workspace migrations, backup procedures, or setting up deployment pipelines in Oracle APEX.
