| A float isn't an exact datatype.Why do you want to use it?If you want the hour then a tinyint would probably do.Otherwise why not a smalldatetime?==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |

Swati, What do you mean by this? Since precision for Real data type is 7 digits, how can you possibly get 0.3 instead of 0.3000000. Otherwise use numeric datatype where you can specify no. of decimal places.Harsh AthalyeIndia."Nothing is Impossible" |

| It's just the way it is converted to characterTry select convert(decimal(18,16),convert(real, 0.3))select convert(real, 0.3)==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |
