Oracle 加入 Vs Informatica 加入

[英]Oracle joins Vs Informatica Joins

原文 2021-01-25 06:09:00 7 2 informatica/ informatica-powercenter/ informatica-powerexchange

I have two Tables A(master) and B (detail)我有两个表 A（主）和 B（详细）

in oracle: A right join B --> Matched records from both + Non matched from Right A left join B --> Matched records from both + Non matched from Left在 oracle 中：A 右连接 B --> 来自两者的匹配记录 + 来自右侧的不匹配 A 左连接 B --> 来自两者的匹配记录 + 来自左侧的不匹配

so what is the equivalent output in informatica?那么在 informatica 中等效的 output 是什么？

2 个解决方案

Oracle and Informatica outer joins works in similar way. Oracle 和 Informatica 外连接的工作方式类似。
In oracle - 'master' right join 'detail' means all matching + non matching from 'detail' In informatica Joiner Transformation, refer to join type in properties,在 oracle - 'master' 右连接 'detail' 表示所有匹配 + 不匹配来自 'detail' 在 informatica Joiner Transformation 中，请参阅属性中的连接类型，

A'Master' outer join means all matching + non matching from 'detail' B A'Master'外连接意味着所有匹配+来自'detail'的非匹配B
'Detail' outer join means all matching + non matching from 'master' A 'Detail' 外连接表示所有匹配 + 来自 'master' A 的不匹配
'Full' outer join means all matching + non matching from 'detail' B+ non matching from 'master' A “完全”外连接意味着所有匹配+来自“详细”B的不匹配+来自“主”A的不匹配

Master outer join: In Master outer join, all rows from the Detail source are returned by the join and only matching rows from the Master source are returned.主外连接：在主外连接中，连接返回来自Detail源的所有行，并且只返回来自Master源的匹配行。

Detail outer join: In detail outer join, only matching rows are returned from the Detail source, and all rows from the Master source are returned.详细外连接：在详细外连接中，从Detail源只返回匹配的行，从Master源返回所有行。

Full outer join: In full outer join, all records from both the sources are returned.完全外连接：在完全外连接中，返回来自两个源的所有记录。 Master outer and Detail outer joins are equivalent to left outer joins in SQL.主外连接和详细外连接相当于 SQL 中的左外连接。

Normal join: In normal join only matching rows are returned from both the sources正常联接：在正常联接中，仅从两个源返回匹配的行
