| Hello all,I am in a bit of a spot, I need to pull a date from a database but it's a 'last used' time. Well if the row has never been used it has no date. So I have a query that is isnull(LastUsed, 'Not Used') But you cannot convert a datetime to a character string so easily I guess because it will not work. I have been searching high and low for an answer but all I can find is how to convert varchar to datetime not the other way around.If any one knows how to do this let me know the closest I got which is still wrong was: isnull(LastUsed, CONVERT(datetime, CONVERT(varchar(10), 'Not Used')))Thanks a million,Tim |

why don't you detect NULL on your front end application and display the 'Not Used' there ?if you want to do this in T-SQL,isnull(convert(varchar(10), LastUsed, 121), 'Not Used') KH[spoiler]Time is always against us[/spoiler] |

High and low? with a few exceptions like google or search option at this site. The below link shows lots of articles and posts about dealing with datetime in SQL.http://www.sqlteam.com/search.aspx?cx=011171816663894899992%3Aaow51lf_dim&cof=FORID%3A9&q=convert+date+to+string&sa=Search#1164 |
