Working with DateTime data types in SQL Server, guidelines and explanations!
Just a bit of basics about DateTime datatype in SQL Server, it has two different date/time columns. They are DATETIME and SMALLDATETIME and the difference between these two SQL Server date/time data types. SQL Server has a number of default formats it expects raw date and time data to be in when inserting dates into a DATETIME, or SMALLDATETIME columns. If you attempt to insert a date that does not match one of the default date formats, then SQL Server will reject the date/time value. If your raw data does match one of the default formats, SQL Server will automatically convert your raw data into a DATETIME value without any special consideration.
Sometimes I get confused with how to deal with various types of formats when you have the data which is globalized in terms of users usability. So here I would like to give you a lead and links on various datetime data types within SQL Server:
