问题 I am attempting to combine two columns (from separate tables) in an access query based on the value of 2 other columns in the tables (semester and student_name in this instance), for instance if I had the following: and how could I make a query to get the final result of: where the third and fourth semester (only the third and fourth) sections of some_data have been combined based on student_name (there may be some names that are in one table, but not in another, etc, although that is not

问题 I'm fairly new to Access. I have a DB table that needs to be normalized. I have some information about a person. These people are authorized to grant access to areas at our work site. Every person may be authorized several times to manage different areas, and of course different people can be authorized to manage different areas. My first try at it was to include the authorization and the areas together, but I realized that I was really repeating the data that way. After doing some study I

问题 I have an activeX treeview control that has 4 levels of nodes (child nodes), each relating to a separate table which is stored on the backend of the database (in-house server). There are 3 queries and 4 dlookups which were required to make this treeview work. As the database has started to become highly populated, the form with the treeview control has become slow to load (10 seconds). I would like to speed up this load time, I think converting to ADO is something I need to at least consider.

问题 The question is given at the end. Before it comes after some details about what I tried. EDIT: I guess in technical terms I am looking for the scrollbar thumb position. Some background on my issue: I have created an access database to store/track issue data at an engineering firm where I work, each issue has 15 or so data fields and a picture. Because of the frequency of out-of-office use (data is stored on network server, db is local to each user) the pictures are not embedded in each record

问题 Has anyone read the MSDN page on using the TRANSFORM statement to create crosstab queries? http://msdn.microsoft.com/en-us/library/office/bb208956(v=office.12).aspx It includes the following assertion, unsupported by code samples: You can also include fixed values for which no data exists to create additional columns. Yes, I would like to create a pivot table with a fixed ordered set of column headings from a pre-existing list. Here's a simplified SQL query: TRANSFORM SUM(tblData.Losses) As

问题 I have a Form that has a button on it. The button basically copies records from one Table to the other. As records are read and copied, it is also checked for specific values. E.g. If one of the fields in the table has a value of "" then it should call another form that allows me to enter a date. Once the date is entered and the form is closed the programme carries on with copying. It can also happen that the key fields in the table that is being copied are duplicate. In this case I should a
