sql - PostgreSQL 检索重复的行记录

Question

我正在运行 PostgreSQL 查询，但它检索到我不需要的重复行记录？＃请帮忙

将不胜感激；如果有人建议或改进我的原始查询，谢谢。

我使用了 distinct、groupby 和 having 子句，但它仍然检索重复的行记录。

SET statement_timeout TO 9000000;

我需要以下格式的输出

您可以在任何查询中使用它：

select distinct * from ($query$) $table_alias_for_query;

更好的方法应该是在原始查询中添加 distinct（我没有在您的查询中注意到 distinct）。
