I have a table of servers that includes a field for a datestamp that indicates when the information was updated. I then have a table full of drive information that also includes historical data from all previous updates. I need the SUM of LogicalDriveSize and LogicalDriveFreeSpace, but only for the dates that are in the ServerData table. Does this make since? Basically it needs to select every record from the ServerDataLogicalDrives table that has a matching ServerName and ExportTime in the ServerData table, then sum the two mentioned fields.
Fields: ExportTime, LogicalDriveSize, LogicalDriveDriveFreeSpace
Fields: ServerName, ExportTime
