问题 I have put two sub-reports in a main report. The main report comes out fine, but the [Enter Year] parameter appears twice: once for each sub-report's query where it occurs. This is normal, and I can probably reduce it to one prompt by writing code. But I think there must be a way to give a named parameter once, and the sub-report queries will pick it up and use it. I would like a non-code method to do this, since next I will do a similar collected report for many sub-reports with shared

问题 I am attempting to normalize a database that uses multiple columns for the same thing. For instance, Street, Street2, ..., Street12 . My current plan is to create a separate Street table, containing columns for Street and mainID , (plus a new ID field for this table,) where mainID is the primary key for the main database. (Example) Each mainID could be linked to multiple Street records as needed, allowing for the removal of the Street columns in the main table. I'm planning to reference this
