I suspect that it's ALWAYS evaluating the second expression and therefore is failing because isn't a valid DT_DATE. The CONVERT () and TRYCONVERT () functions can convert United States datetime format (month, day, year and time) by default, therefore, you don’t need to specify style 101: In this tutorial, you have learned how to convert a string to a datetime using the CONVERT () and TRYCONVERT () functions. Use the function TODATE() to convert a text value containing a date to the date data type. I don't like this as it's terribly inefficient. I the run a post processing command to clean that up with REPLACENULL to Nullify the values meeting that criteria. None of the styles that the CONVERT function supports accept the way your datetimes are formatted. I just need the time added to the DateTime value but it does not like the time being added. I worked around this as such to check each part to ensure it was a valid date component: Because '20100106' is a valid string literal expression for a datetime. The first argument is the string that you want to convert to a date. When attempting to use a derrived column to extract this information, I am running into the issue that 00-00-00 is not a valid DT_DATE. The TODATE() function accepts two string arguments. I have a flat text file that stores a date as YYMMDD that could also be 000000.
