QuestionSQL Server null date 01/01/1900 possible issue - a question Pin
GuyThiebaut1-May-13 5:51
memberGuyThiebaut1-May-13 5:51 
SQL Server will return a null date as 01/01/1900 if one castes a null string to a date.

Now the issue is that someone had the idea of populating dates with 01/01/1900 to signify a certain stage with a row(meaning that the date is not known but it is known that that stage has been reached).

I only realised yesterday that this could cause an issue if a query is written where a null string is compared to one of these dates.

Does anyone else have experience of this and any suggestions?
I am currently thinking of changing these 01/01/1900 dates to 01/01/1901 to remedy this potential problem.

Thanks
