Function global_sql_cache 

pub fn global_sql_cache() -> &'static SqlTemplateCache

Global SQL template cache for common query patterns.

This provides a shared cache across the application for frequently used SQL templates, reducing memory usage and improving performance.

Example

use prax_query::sql::{global_sql_cache, DatabaseType};

let sql = global_sql_cache().get_or_insert("find_user_by_id", DatabaseType::PostgreSQL, || {
    "SELECT * FROM users WHERE id = $1".to_string()
});
