在Jinja 中,您可以使用该{% if [not] loop.last %}位,让程序知道每当您处理循环中的最后一次迭代(或除最后一次之外的所有迭代,因此在其中[not])时,您需要不同的行为。 例如,在您的示例中,您可以使用以下内容: {% macro concatenate_columns() %} {%forcolumnin[col_1, col_2, col_3] %}"{{column...
Macros (宏编程)是dbt的高级功能,可以更方便的拼接各种SQL组件,并可以组合成一些宏函数,从而组装成无比复杂的程序。 可以参考https://docs.getdbt.com/tutorial/using-jinja来了解dbt中Macros的使用场景。 比如,BI等数据分析中一个常用的场景是 pivot 操作。如果不使用宏,那么,SQL可能会写为: selectorder_id,sum...

说明 namespace 实际属于jinja2 的特性,只是dbt 使用了此特性而已,所以看到部分dbt macro 使用此定义不应该陌生 参考资料 dbt/include/global_project/macros/materializations/snapshots/strategies.sql https://jinja.palletsprojects.com/en/3.0.x/templates/

This macro is useful for transforming Jinja strings into "slugs", and can be useful when using a Jinja object as a column name, especially when that Jinja object is not hardcoded. For this example, let's pretend that we have payment methods in our payments table like ['venmo App', 'ca...
