Aug 28, 2013 at 20:29 | comment | added | Lorenz Meyer | @jon You're right, this makes no sense. The problem is with my application. I guess I have to look how to modify the application in order to accept a simplified database. It will be kind of a nightmare ... | |

Aug 28, 2013 at 14:24 | comment | added | Jon of All Trades | Can you clarify the business goal? I wonder why you'd really always have the same value for every row. The same few values, sure, even one of two for each row, but the same? | |

@a_horse_with_no_name: a computed column is not stored - it's computed every time you access it - unless you specify PERSISTED , then it's persisted like a normal column (and thus doesn't save any space)

Aug 28, 2013 at 14:13 | comment | added | marc_s | If you use a normal computed column - then yes, you might save a bit on disk space - BUT always constantly re-computing those values will most likely cost you more in terms of processing time than you save by loading less data | |

Aug 28, 2013 at 12:56 | comment | added | Thronk | "I think about replace the with a constant calculated column" - this line does not make sense to me and maybe your question did not make it into SO as you intended. Could you elaborate? | |
