如何在 Informatica Power Center 中从多个表生成单个文件

Question

How to Generate a Single file from multiple tables in Informatica Power Center like below...

Answer 1

I think we can do this using UNION ALL . Assuming 3 files are read from different sources,

1. Create three expression transformations with 3 ports. This is Exp1, 2, and 3 in below pic. For Exp1-
   out_concat_all = Name1 ||'|'||FirstName1||'|'||... and so on.
   in_NEXTVAL = Add NEXTVAL from new sequence generator.
   out_SEQ = 'File1`||in_NEXTVAL Pls make similar logic as per file2 and file3.
2. Create a UNION ALL to combine above 3 pipelines into one pipeline.
3. Sort the data based on SEQ column.
4. Link only concat_all column into a target file. Whole flow should look like this -
