In my sql server table i tried to load data using ssis data flow task and stored procedure in both the methods my created date for every rows is same time stamp for all the 50 k records. I am using constraint in my created column with default value as getdate(). I also i have updated date column there i have no constraints. In the derived column i am using getdate() to load the data in the stored procedure also i am using getdate() but still updated column value also same for All the 50 k records What could be issue? Have you ever faced this before

[@learnssis]

Are you getting Updated column value from source ? Can you check the data in source ? And check the mapping in the destination table. Make sure you are correctly mapping the updated column.

@@learnssis no Actually my source is flat file. I am just using getdate() in my derived column and assigning it to my updatedDate filed. Yes mapping is correct actually for all my tables I am facing the same issue for createdDate and updated date. FYIP it's a new database and server and this is our first project. My 150k records loaded in 75 secs along with Look up from 9M records from edw.

@@maham4062 So if you are using getDate in derived column then mapping it with update date then of course update date will be same for all 50 k records because you are assigning the getdate value to update date column. Are you directly importing data from flat file to sql server table or using a lookup component to check if a record already exists in sql server table or not ?

@@learnssis loading data directly from source file to SQL server table. Also I am using constraints for createdDate to use getdate() as default there also I am getting the same date for all the 50k records. How to resolve updatedDate issue? What should I do instead of the Drived Column transformation?
