通用/动态SQL函数：如何实现任意表数据的字符串拼接？

Let’s break down each formatting rule with straightforward examples so you can apply them easily in your content:

Headings #

Use number signs (#) to create hierarchical headings—more #s mean a lower heading level:

• # Heading Level 1 → renders as:

• ## Heading Level 2 → renders as:

Heading Level 2 #

• ### Heading Level 3 → renders as:

Heading Level 3 #

List Items #

Start each unordered list item with a dash (-). You can nest sub-items by indenting them:

• First main list item
• Second main list item
  • Nested sub-item 1
  • Nested sub-item 2

Emphasized Text #

Wrap text in asterisks to add visual emphasis:

• Single asterisks for italicized text: *italicized text*
• Double asterisks for bolded text: **bolded text**

Code or Commands #

Use backticks to distinguish code from regular text:

• Inline code/commands: Wrap in single backticks, like git commit -m "Initial commit"
• Multi-line code blocks: Wrap in three backticks at the start and end:

def calculate_sum(a, b):
    return a + b

result = calculate_sum(5, 3)
print(result)

Quoted Text #

Use a greater-than sign (>) to format blockquotes. For nested quotes, add an extra >:

This is a basic blockquote.

This is a nested quote inside the first one.

Links #

Structure links as [Display Text](URL)—the display text is what readers see, and the URL is where the link leads:

• Example: [My Project](https://example.com/project) → renders as My Project

Images #

Format images with descriptive alt text (for accessibility and when images fail to load) followed by the image URL:

• Example: [Sunset Over Mountains](https://example.com/sunset.jpg) → displays the image with "Sunset Over Mountains" as alt text.
