There is no data format in MySQL which will save just the Time: it must have a date attached in order to be useful.

The way I would do this is to store it as "minutes since midnight" in an integer, and convert it back to HH:MM when I extracted it. That way, you can do sorting and comparisons etc. and still easily retrieve the values for display.

And please, do not concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.

THANKS FOR UR SUGGESTION!
BUT IF I SAVE THE DATA WITH DATE AND TIME IN SAME COLUMN HOW I WILL FILTER IT DURING SELECT COMMAND BETWEN TWO DATES.

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

If you want to rewrite that in proper capitalisation, I might read it, but I am not even going to glance at the content as it is.

Ok Sir,

[no name] 7-Sep-13 4:55am

if we save our data using DateTime datatype, with date and time simultaneously, how to filter my select query between two dates.
plz plz Reply.

That's easy: if you store a single DateTime value with the date and time combined, then all you have to do is use BETWEEN:
SqlCommand cmd = new SqlCommand("SELECT * FROM MyTable WHERE MyDateColumn BETWEEN @STARTDATE AND @ENDDATE", con);
cmd.Parameters.AddWithValue("@STARTDATE", startDateAndTime);
cmd.Parameters.AddWithValue("@ENDDATE", DateTime.Now);

If you are using DataType "DATETIME" for Complain Time field, I dont think you can store only the time. Instead you change the DataType into TIME for Complain Time field and use the below format to extract time alone.
Do not pass time string alone and pass the date as Parameter and extract the time using like this.

insert into testtime values(2,TIME('2011-12-31 01:02:03'));

this will take only the time from the given date - "01:02:03".
