如何在Informatica Cloud中使用多字符定界符？

Question

I have a problem I need help solving. The business I am working for is using Informatica cloud to do alot of their ETL into AWS and Other Services.

We have been given a flat file by the business where the field delimiter is "~|" Currently to the best of my knowledge informatica only accepts a single character delimiter.

Does any one know how to overcome this?

Answer 1

Informatica cannot read composite delimiters .

First you could feed each line as one single long string into an Expression transformation. In this case the delimiter character should be set to \\037 , I haven't seen this character (ASCII Unit Separator) in use at least since 1982. Then use repetitive invocations of InStr() within the EXP to identify the positions of those double pipe characters and split up each line into fields using SubStr().

Second (easier in the mapping, more work with the session) you could feed the file into some utility which replaces those double pipe characters by the character ASCII 31 (the Unit Separator mentioned above); the session has to be set up such that it reads the output from this utility (input file type = Command instead of File). Then the source definition should contain the \\037 as the field delimiter instead of any pipe character or so.
