+-- CREATE TICKET SUPPORT TABLE
+-- Date: 2026-03-09
+-- ==============================================
+
+-- 1. Create a sequence for the ticket number
+CREATE SEQUENCE IF NOT EXISTS ticket_number_seq START 1001;
+
+-- 2. Create the ticket_support table
+CREATE TABLE IF NOT EXISTS ticket_support (
+    id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
+    ticket_number TEXT UNIQUE NOT NULL,
+    user_id UUID REFERENCES codev(id) ON DELETE SET NULL,
+    full_name TEXT NOT NULL,
+    email TEXT,
+    role_position TEXT,
+    project_id UUID REFERENCES project(id) ON DELETE SET NULL,
+    assigned_team TEXT,
+    ticket_type TEXT NOT NULL,
+    other_type TEXT,
+    subject TEXT, -- This will correspond to 'ticketTitle' from frontend
+    message TEXT NOT NULL, -- This will correspond to 'ticketDetails' from frontend
+    status TEXT NOT NULL DEFAULT 'PENDING' CHECK (status IN ('PENDING', 'OPEN', 'IN_PROGRESS', 'RESOLVED', 'CLOSED')),
+    priority TEXT NOT NULL DEFAULT 'MEDIUM' CHECK (priority IN ('LOW', 'MEDIUM', 'HIGH', 'URGENT')),
+    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
+    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
+);
+
+-- 3. Create a function to generate the formatted ticket number
+CREATE OR REPLACE FUNCTION generate_ticket_number()
+RETURNS TRIGGER AS $$
+BEGIN
+    IF NEW.ticket_number IS NULL THEN
+        NEW.ticket_number := 'TS-' || LPAD(nextval('ticket_number_seq')::text, 6, '0');
+    END IF;
+    RETURN NEW;
+END;
+$$ LANGUAGE plpgsql;
+
+-- 4. Create the shared update_updated_at_column function if it doesn't exist
+CREATE OR REPLACE FUNCTION update_updated_at_column()
+RETURNS TRIGGER AS $$
+BEGIN
+    NEW.updated_at = NOW();
+    RETURN NEW;
+END;
+$$ language 'plpgsql';
+
+-- 5. Create trigger to auto-generate ticket number before insert
+CREATE TRIGGER set_ticket_number
+    BEFORE INSERT ON ticket_support
+    FOR EACH ROW
+    EXECUTE FUNCTION generate_ticket_number();
+
+-- 6. Create trigger to update updated_at timestamp
+CREATE TRIGGER update_ticket_support_updated_at
+    BEFORE UPDATE ON ticket_support
+    FOR EACH ROW
+    EXECUTE FUNCTION update_updated_at_column();
+
+-- 7. Enable Row Level Security (RLS)
+ALTER TABLE ticket_support ENABLE ROW LEVEL SECURITY;
+
+-- 8. Define RLS Policies
+
+-- Policy: Authenticated users can create tickets
+CREATE POLICY "Authenticated users can create tickets"
+    ON ticket_support FOR INSERT
+    TO authenticated
+    WITH CHECK (auth.uid() = user_id OR user_id IS NULL);
+
+-- Policy: Users can view their own tickets
+CREATE POLICY "Users can view own tickets"
+    ON ticket_support FOR SELECT
+    TO authenticated
+    USING (auth.uid() = user_id);
+
+-- Policy: Admins can manage all tickets
+CREATE POLICY "Admins can manage all tickets"
+    ON ticket_support FOR ALL
+    TO authenticated
+    USING (
+        EXISTS (
+            SELECT 1 FROM codev 
+            WHERE id = auth.uid() 
+            AND (internal_status = 'ADMIN' OR role_id IN (SELECT id FROM roles WHERE (name ILIKE '%admin%' OR name ILIKE '%super%')))
+        )
+    );
+
+-- 8. Create Indexes for performance
+CREATE INDEX IF NOT EXISTS idx_ticket_support_ticket_number ON ticket_support(ticket_number);
+CREATE INDEX IF NOT EXISTS idx_ticket_support_user_id ON ticket_support(user_id);
+CREATE INDEX IF NOT EXISTS idx_ticket_support_status ON ticket_support(status);
+CREATE INDEX IF NOT EXISTS idx_ticket_support_created_at ON ticket_support(created_at);
+
+-- 9. Comment on table
+COMMENT ON TABLE ticket_support IS 'Stores support tickets submitted by users.';
