嘿大家我是oracle的新手，我受到了这个声明的打击，我无法弄清楚正在发生什么样的加入可以让任何人帮助我吗？
这是我无法说清楚的声明。 这样做有什么联系？ 内部联接？ 全外连接？ 右外连接？ 左外加？
AND TO_DATE(&&SYS_DT, 'DD-MON-YY') BETWEEN R.BEG_EFFECTIVE_DT(+) AND R.END_EFFECTIVE_DT(+)

答案 0 :(得分：0)
这是过时的Oracle OUTER JOIN符号。
此WHERE条件：
AND TO_DATE(&&SYS_DT, 'DD-MON-YY') BETWEEN R.BEG_EFFECTIVE_DT(+) AND R.END_EFFECTIVE_DT(+)
等同于
LEFT JOIN
r
ON TO_DATE(&&SYS_DT, 'DD-MON-YY') BETWEEN R.BEG_EFFECTIVE_DT AND R.END_EFFECTIVE_DT
