Struct TemplateInterceptor

pub struct TemplateInterceptor { /* private fields */ }

Templated query, powered by minijinja. The template syntax can be found here.

Grammar:

-- SQLNESS TEMPLATE <json>

json define data bindings passed to template, it should be a valid JSON string.

Example

.sql file:

-- SQLNESS TEMPLATE {"name": "test"}
SELECT * FROM table where name = "{{name}}"

.result file:

-- SQLNESS TEMPLATE {"name": "test"}
SELECT * FROM table where name = "test";

In order to generate multiple queries, you can use the builtin function sql_delimiter() to insert a delimiter.
