Question

I have a table called node_status which has three columns:

1. id (int)
2. status (bit)
3. modifiedtime (smalldatetime)

I want to run a query on it such that if any row in the table contains a modifiedtime value which is more than 5 minutes before the current time then the status column set to 0 (false).

Can any body tell me how to do this? (using SQL Server)

Thanks

When you want to do a query based on the current time you can use getdate(), and use the dateadd function to add or remove amounts of time from a date. As such:

update 
     node_status 
set 
     status = 0 
where 
     modifiedtime < dateadd(minute, -5, getdate())
