QUESTION
I have a problem regarding update of end date of previous record using the next records start date. The problem is both the records coming in, in the same table load. Also there is no unique row identifier except the combination of all columns. Example: Source Table
...ANSWER
Answered 2017-Oct-18 at 18:39Try these options:
Create a column in target table like ROW_ID with VARCHAR2(100)
Create an Expression in Expression transformation with following -
MD5(Col1||''||col2||''||...etc)
'*' - is an separator to get precised output
This MD5 function will generate an 32 bit mask which we will use it in next steps
Have a Dynamic lookup on the target table
Now, every time when you receive a new row it will get added to target as well as Dynamic lookup. Hence, if you try to Match the ROW_ID field with 2nd rows calculated ROW_ID, you can easily find out the duplicate record.
MD5 is one of the best and fastest way to find dups using whole column list. DO NOT foget to create Dynamic Lookup otherwise you wont be able to find dups.
Let me know if you need further info.
