| Not sure what you mean.You have a column called [top 100 rows] which you want updated with a random number?You want a column updated on the the top 100 rows - in which case you need to say what you mean by te top 100?You want the numbers 1 - 100 randomly allocated to a column?==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |
