| I have no idea what I'm doing so I could use some help! Basically I have two columns, field_id and value, that need editing and I need to do something like this:When field_id = 2 then value changes to 2 decimal places.The farthest I got was figuring out that SET value = ROUND(value,2) adds on decimals, but that would effect the entire column versus just the ones I need. Help please! |

| The case statement is pretty powerful. You can also use it for dynamic sorts. I would highly recommend you learn the syntax well. I've used it on countless probjects.Greghttp://www.freewebstore.org/tsqlcoderepositoryPowerful tool for SQL Server development |
