填充Informatica目标表

Question

I am new in Informatica,here i am trying to populate my target table by joining two tables where the no. of rows in both the table is 5649 and 2611 respectively.So, my output rows should be 8260.But the no. of rows rows in target table is around 108860 (approx.).

Why this is happening and how should I remove it?

Answer 1

It seems to me that you are confusing the join operation with union .

You need to merge two sets of rows into one, so use a Union transformation, not a Joiner .

Answer 2

如果表结构不同，则仅选择/选择公共列，然后在SQ Override中执行并集。
