I want to import flat file to my Database using SSIS. File name has both date and time of generation. for example, file name is: report_20180820_09_25_18.csv. I've defined the expression to change the date part automatically. for the time part, since report is generated on different time each day, i need to define a expression in which SSIS looks for a file that the name is like report_20180820_*.csv (* means anything) Is there an solution to this issue?
