Seems like last accessed on  is a date time  and you are converting  23-07-2014 09 37 00  to a varchar  This would not work  and give you conversion errors  Try   last accessed on  convert datetime  23-07-2014 09 37 00   103      I think you can avoid the cast though  and update with  23-07-2014 09 37 00   It should work given that the format is correct   Your query is not going to work because in last accessed on  which is DateTime2 type   you are trying to pass a Varchar value   You query would be  UPDATE  student queues SET  Deleted 0    last accessed by  raja   last accessed on convert datetime  23-07-2014 09 37 00   103     WHERE std id IN   2144-384-11564   AND reject details  REJECT

If you re trying to insert in to last accessed on  which is a DateTime2  then your issue is with the fact that you are converting it to a varchar in a format that SQL doesn t understand   If you modify your code to this  it should work  note the format of your date has been changed to  YYYY-MM-DD hh mm ss   UPDATE  student queues  SET  Deleted 0        last accessed by  raja         last accessed on CONVERT datetime2  2014-07-23 09 37 00   WHERE std id IN   2144-384-11564   AND reject details  REJECT    Or if you want to use CAST  replace with   CAST  2014-07-23 09 37 00 000  AS datetime2    This is using the SQL ISO Date Format
