We've restricted the ability to create new threads on these forums. I agree that we cant use 6 digit milliseconds but if i change my data type from datetime to varchar(45) then is this feasible means changing datatype from datetime to varchar(45) is benefit as far as my 6 digit issue consideration??? If u r not worried much about the precision, u may use it as followsprint convert(datetime,convert(varchar(23), '2006-03-31 .933456'))(U have to put it for update as necessary)Srinika hi.are using this field to sort the duplicate issue...this field having same values then we mark it as duplicate so for accuracy purpose we need 6 digit milliseconds and we need to implement it as early as possible so pls help me out if u have way!!! and wheather its selection is logically correcti am getting answer is Apr 7 2006 PMwhich is logicaaly wrong :( :(pls help me out with solution T. Please guide me if i m in wrong way say if i change its data type from DATETIME to varchar(45) then in that if i want to compare this DATE field by MAX(DATE_T) then how varchar behave for example i have records for this field are....insert into emp(id,date_t) values(72,'04/07/2006 .123456')insert into emp(id,date_t) values(52,'04/07/2006 .123456')insert into emp(id) values(22) ---default is getdate()-- value Apr 7 2006 PMand if i fired like select max(date_t) from empthen what it select???A datetime value is always stored in a binary form.You can do some formattinig when you select the data.Could someone help me with the most efficient way to update a date field.I have a field with Date and Time in it but I want to update it with only the Date and strip off the time. DATETIME / SMALLDATETIME columns always contain both date and time.
Which database are you using e.g with My SQL you'd have to do HI, DO THE FOLLOWING: 1.Using the example above if you didn't have First Name = 'Stephen' in your WHERE criteria, you would have updated 2 records (Susan Grant and Stephen Grant), because both these users have one and the same last name.Hi there, just moving your post to one of the SQL forums, where the experts will be far better qualified to address your query.The second row is the row that defines the changes made to the database fields using the keyword SET followed by the column name, equal sign and the new value for this column.You can have more than one assignment of new value after the SET keyword, for example if you want to update both the email and the city you will use the SQL statement below: The third line is our WHERE clause, which specifies which record(s) to update.
To do that, use the following SQL statement: In both UPDATE example having WHERE clause above, I've changed a table field to new value, using the same field in the WHERE clause criteria.
