SQL Query Templates

Ready-to-use boilerplate for common query patterns — CTEs, joins, date rollups, window functions, and stored procedures. Click Copy and adapt the table/column names.

CTE

Basic CTE (Common Table Expression)

Break a query into a readable, reusable named block.

WITH recent_orders AS (
    SELECT
        customer_id,
        order_id,
        order_date,
        total_amount
    FROM orders
    WHERE order_date >= DATEADD(day, -30, GETDATE())
)
SELECT
    customer_id,
    COUNT(order_id)   AS order_count,
    SUM(total_amount) AS total_spent
FROM recent_orders
GROUP BY customer_id
ORDER BY total_spent DESC;

Recursive CTE (hierarchy / org chart)

Walk a parent-child tree, e.g. an employee/manager hierarchy.

WITH RECURSIVE employee_hierarchy AS (
    -- Anchor: top-level rows (no manager)
    SELECT
        employee_id,
        manager_id,
        employee_name,
        1 AS level
    FROM employees
    WHERE manager_id IS NULL

    UNION ALL

    -- Recursive: join children to their parent's result
    SELECT
        e.employee_id,
        e.manager_id,
        e.employee_name,
        eh.level + 1
    FROM employees e
    INNER JOIN employee_hierarchy eh
        ON e.manager_id = eh.employee_id
)
SELECT *
FROM employee_hierarchy
ORDER BY level, employee_name;
-- Note: SQL Server / Oracle: drop the RECURSIVE keyword (just WITH employee_hierarchy AS (...))

Joins

INNER / LEFT JOIN across multiple tables

Combine orders with customers and line items in one query.

SELECT
    o.order_id,
    c.customer_name,
    o.order_date,
    p.product_name,
    oi.quantity
FROM orders o
INNER JOIN customers c
    ON o.customer_id = c.customer_id
LEFT JOIN order_items oi
    ON o.order_id = oi.order_id
LEFT JOIN products p
    ON oi.product_id = p.product_id
WHERE o.order_date >= '2026-01-01'
ORDER BY o.order_date DESC;

GROUP BY / Dates

Monthly rollup with GROUP BY on a date

Aggregate a date column by month (swap the truncation line for your engine).

SELECT
    DATE_TRUNC('month', order_date) AS order_month,     -- PostgreSQL
    -- FORMAT(order_date, 'yyyy-MM')  AS order_month,    -- SQL Server
    -- DATE_FORMAT(order_date, '%Y-%m') AS order_month,  -- MySQL
    COUNT(*)          AS order_count,
    SUM(total_amount) AS revenue
FROM orders
GROUP BY DATE_TRUNC('month', order_date)
ORDER BY order_month;

Window Functions

ROW_NUMBER + running total

Rank each customer's orders and compute a running total.

SELECT
    customer_id,
    order_id,
    order_date,
    total_amount,
    ROW_NUMBER() OVER (
        PARTITION BY customer_id
        ORDER BY order_date DESC
    ) AS order_rank,
    SUM(total_amount) OVER (
        PARTITION BY customer_id
        ORDER BY order_date
        ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
    ) AS running_total
FROM orders;

Stored Procedures

Parameterized stored procedure

A basic proc with optional date-range filters (T-SQL syntax).

CREATE PROCEDURE GetCustomerOrders
    @CustomerId INT,
    @StartDate  DATE = NULL,
    @EndDate    DATE = NULL
AS
BEGIN
    SET NOCOUNT ON;

    SELECT
        order_id,
        order_date,
        total_amount
    FROM orders
    WHERE customer_id = @CustomerId
        AND (@StartDate IS NULL OR order_date >= @StartDate)
        AND (@EndDate   IS NULL OR order_date <= @EndDate)
    ORDER BY order_date DESC;
END;
-- Call it: EXEC GetCustomerOrders @CustomerId = 101, @StartDate = '2026-01-01';

Upsert / Merge

MERGE (upsert) from a staging table

Insert new rows and update matching ones in a single statement.

MERGE INTO customers AS target
USING staging_customers AS source
    ON target.customer_id = source.customer_id
WHEN MATCHED THEN
    UPDATE SET
        target.customer_name = source.customer_name,
        target.email         = source.email,
        target.updated_at    = GETDATE()
WHEN NOT MATCHED THEN
    INSERT (customer_id, customer_name, email, created_at)
    VALUES (source.customer_id, source.customer_name, source.email, GETDATE());

Flow Planner — Draw Flowcharts & Diagrams Online

The Flow Planner lets you sketch flows and diagrams using draggable shapes and arrow connectors, then export the finished board as a PNG. It's built for anyone who needs a lightweight online flowchart maker for planning a process, mapping a workflow, or sketching a decision tree — without the complexity of full diagramming software. Add shapes, connect them, and export — all in your browser.

⚡ Key Takeaways

Four base shapes with drag-to-connect arrows and inline text editing.
Connectors can be repointed by dragging an endpoint, not just deleted and redrawn.
Export the finished board as a high-resolution PNG in one click.
Best for quick, general-purpose sketches rather than strict UML notation.

What, Who, When & Why

What it's for	A visual board for sketching flowcharts and diagrams using draggable shapes and connectors.
Who it's for	Anyone planning a process, workflow, or decision tree who wants a quick visual without full diagramming software.
When to use it	During planning discussions, process documentation, or any time an idea is easier to explain visually than in text.
Why it's needed	Full diagramming software is often more complex than needed for a quick sketch, and text descriptions of a process are harder to follow than a diagram.
Best way to use it	Use diamonds for decision points and rectangles for process steps consistently, following common flowchart conventions.

How to Use the Flow Planner

Click a shape button (Rectangle, Square, Circle, or Diamond) to add it to the board.
Drag shapes to arrange them, or drag the corner handle on a selected shape to resize it.
Double-click a shape to type text directly inside it.
Drag from a shape's blue connection dot onto another shape to draw an arrow between them.
Click a connector to select it — drag an endpoint to repoint it to a different shape, or click 🗑 to delete it.
Click ⤢ to expand the board full-screen, and 📸 to export the finished diagram as a PNG.

Example

A simple approval process might use a rectangle labeled "Submit Request," connected to a diamond labeled "Approved?", which branches to two more rectangles: "Process Order" if yes, and "Notify Rejection" if no. Building this takes just a few clicks — add each shape, type its label by double-clicking, then drag connectors between them to show the flow of the process.

Key Features

Four base shapes: rectangle, square, circle, and diamond.
Inline text editing directly inside each shape.
Drag-to-connect arrows between shapes, with live preview while dragging.
Repointable connectors — drag an existing connector's endpoint to a different shape instead of deleting and redrawing.
Resizable shapes for fitting more text.
Color palette for organizing shapes by category or type.
Full-screen expand mode for focused diagramming.
Export the finished board as a high-resolution PNG.
Auto-saves to your browser between visits.

Practical Use Cases

Process mapping: sketch out a business process or workflow step by step.
Decision trees: use diamond shapes to represent decision points with branching arrows.
System diagrams: map out how components in a system connect and interact.
Planning discussions: quickly visualize an idea during a meeting or brainstorming session, then export it to share.
Onboarding documentation: create a simple visual guide showing the steps in a recurring process.

Tips for Best Results

Use diamonds consistently for decision points and rectangles for process steps, following common flowchart conventions, to make the diagram easier for others to read.
Color-code shapes by team, status, or category to make a complex diagram easier to scan at a glance.
Expand to full screen before doing detailed layout work on a larger diagram, then export once you're happy with the arrangement.

Related Terminology

A flowchart uses connected shapes to represent a sequence of steps or decisions, with different shapes conventionally representing different types of steps — diamonds often represent decision points, while rectangles represent process steps, and circles or ovals commonly mark the start and end points of a process.

Important Considerations

The board is designed for general-purpose diagramming rather than formal UML or specialized notation — if you need strict adherence to a particular diagramming standard, treat this as a quick sketching tool rather than a fully compliant diagramming application. Diagrams are saved to your browser's local storage, so they're tied to your current device and browser rather than syncing automatically elsewhere.

Frequently Asked Questions

How do I add text inside a shape?

Double-click the shape — an inline text box appears directly on top of it, ready to type into.

How do I connect two shapes with an arrow?

Hover over a shape to reveal small blue dots at its edges, then drag from one of those dots onto the shape you want to connect to.

Can I move a connector to a different shape after drawing it?

Yes, click the connector to select it, then drag either endpoint onto a different shape to repoint it without needing to delete and redraw it.

Can I export my diagram as an image?

Yes, click the 📸 export button to download the entire board as a PNG image.

Will my diagram be there if I come back later?

Yes, the board auto-saves to your browser's local storage, so it will still be there the next time you visit on the same device and browser.
