Select item_pk_id from item where upc='7300156576798';
61564
Delete from price where item_pk_id='61564';
Delete from item where upc='7300156576798';
61564来自第一个查询,是否可以简化此过程,所以我只需要在顶部输入UPC作为变量? 现在,我必须运行所有3个查询。
像这样
SET x = '7300156576798'
y = Select item_pk_id from item where upc= x;
Delete from price where item_pk_id=y;
Delete from item where upc=x;
此命令在SQL编辑器/ postgresql #postgresql中运行,以从大型数据库中删除som项目。
