I need to add a Dynamic Content in an ADF. In such a way that it needs to get last month date as below formate.

Result: 2018-12.csv.zip

If you set the date to the 28th and then subtract 30 days, that should get you into the previous month from any date. Then simply format as yyyy-MM, eg

@concat(formatDateTime(adddays(formatDateTime(utcnow(), 'yyyy-MM-28'),-30),'yyyy-MM'),'.csv.zip')

Azure Data Factory V2 is a powerful data service ready to tackle any challenge. A common task includes movement of data based upon some characteristic of the data file. By combining Azure Data Factory V2 Dynamic Content and Activities, we can build in our own logical data movement solutions.

This can be done by using https://docs.microsoft.com/en-us/azure/data-factory/control-flow-expression-language-functions.

Possible solution: I will suggest you to use 3 parameters here. This solution use trigger().startTime, but you can use utcnow() aswell.

Note: adddays(trigger().startTime,-31,'MM') will return 12 as month, as that month was 31 days ago. If your trigger is on 5th of the month, or on the first day in the month than you can use -2.

processYear = @formatDateTime(adddays(trigger().startTime,-31), 'yyyy')

processMonth = @formatDateTime(adddays(trigger().startTime,-31), 'MM')

result = @concat(pipeline().parameters.processYear,'-',pipeline().parameters.processMonth,'.csv.zip').

Hope that this helps.

On the left of the Azure portal menu, select Create a resource > Analytics > Data Factory. On the New data factory page, enter ADFTutorialBulkCopyDF for name.

Above given case works, if I know the date but I am running my Data Factory every day. So below works better.

@concat(substring(string(if(equals(int(formatDateTime(utcnow(), 'MM')),01), sub(int(formatDateTime(utcnow(), 'yyyyMM')),89),sub(int(formatDateTime(utcnow(),'yyyyMM')),1))),0,4),'-',substring(string(if(equals(int(formatDateTime(utcnow(), 'MM')),01), sub(int(formatDateTime(utcnow(), 'yyyyMM')),89),sub(int(formatDateTime(utcnow(),'yyyyMM')),1))),4,2),'.csv.zip')

Any changes appreciated.
