Basic Variable Substitution
You can reference variables in your SQL queries using double curly braces:Conditional Query Blocks
You can use Jinja-style control structures to include or exclude parts of your query based on variable values:Using Multiple Variables
Combine several variables for more complex filtering:Example: Dynamic LIMIT
You can use variables to control query limits:Example: IN Clauses with Lists
If your variable is a list, you can use Jinja to join values for an IN clause:Best Practices
- Always provide sensible defaults for variables to avoid empty queries.
- Use
{% if ... %}
blocks to prevent SQL errors when variables are empty or unset. - Sanitize and validate user input where possible.
Reference: Jinja Syntax
{{ variable }}
: Insert variable value{% if ... %} ... {% endif %}
: Conditional blocks{% for ... %} ... {% endfor %}
: Loops (for advanced use)- Filters like
| join(", ")
for lists
