Hello,

I am using crc32 function to calculate row value for type2 changes.
I did crc32 on one data set in development project and used the same data set
in UAT to do crc32. I expected both the values to be same but they are different.

In short crc32 value in development is different from UAT for the same row

Thanks in advance

Regards

sorry i forgot add my question.

why is it different from project to project?

As far as I know it should not be , check if there are some extra spaces or any extra characters in ur UAT data?

It should not matter what the actual generated CRC value is, provided it remains consistent for all given values on any one platform.

The mathematics of a CRC32 computation are bit-oriented so should not be different unless you are using different code. Are you certain your versions of DataStage are exactly identical?

Or different byte order, or different separator, or different column order, or maybe other differences; even the character order can be significant.
