Want to do delta loads for your Data Warehouse and having problems in storing Last Load time in an SSIS DateTime Variable?
SSIS DateTime data type truncates the milliseconds from the DateTime. To avoid this set the data type for the variable to store the Last Load time as String. e.g.
SELECT CONVERT(VARCHAR(23), LastModified, 121) LastModified FROM ........
Then you can change it to DateTime before passing it back to the database.
.......WHERE LastModified > CONVERT(DATETIME, @LastModified, 121)
