I have tables inside a schema inside a DB. I need dbvis to graph/show the actual lines that show the relationships among the PKs as in the link below.

For some reason, I can only get dbvis to display the column name and type in the diagram, but no PKs or links show up. How can I get these to show on the graph/diagram?

I have 2 tables in my visualization. One is a list of tasks to be done, and one is a list of repairs that have been done at each location. I want to be able to filter the repairs table by the locations of the highlighted tasks. Ergo if you marked a task that takes place at location 1, the second table would filter to only show repairs for location 1. Is that something that's doable?
Thanks in advance
This is pretty easy to do. You need to create a relation on the Location column between your two tables (Data table properties, Relations tab). Then create a details visualization (right click on "parent" table and select details visualization). Because you have created the relation already, it will ask you which table you want to be the "child". After selecting which table, you will be able to click on the parent, and it will filter in the child table. Also note, using the right click menu is engaging the data limiting with marking, which you will be able to see in the properties dialog, data menu. You don't have to use the right click menu to setup details visualizations. It's just easy.
I've written a lot about how to use relations and column matches. See links below. Relations integrate filtering, which is what you want. Column matches integrate marking.

I would like to create a database to load my trucks at a certain time and on a certain dock. So for example truck A should load on dock 1 at 6 am. The problem is that I don't know how to get the different IDs of my docks. I create a parameter called id but don't know which ID my different docks have which I write into my database.
Database
]1
agent/population_dock
Create a new dbase table "docks" with an int-column "dock_id". Fill it with as many docks as you want to create and give them an id number.
In your existing table, link the "id" column to that new table "dock_id".
When you create "Dock" agents in your population "loadDocks", you can select "loaded from database". Create 1 agent for each record in table "docks" and map the "dock_id" column to your parameter "Dock.id".
Now each dock knows its id.
Lots of AnyLogic example models use this setup, so check these out as well (search for "database"). And read around in the help, this is documented very well :)
I'm trying to create a form to fill three tables to describe some projects with the 'Title of the project' as common field. When I create the form I have to write the title three times, otherwise it's not posible to fill the tables. Is there any way to put just one of the three fields on the form but the three of them are filled?
The database is empty, I want to make a form to start introducing all the projects that are going to be done in my group of work. In one table there are data related to the project, like start dat , full budget etc. In another one the information about my company, like the group its doing it, its role etc. In the last one just some general information like related tags. The name of the project appears in all of them, but when I do the form from a query they seem not to be related even if I do it on the query.
I've already tried to do it with the Wizard tool, selecting the different tables and its fields. I also tried to check the form properties...but I can't come up with what I'm doing wrong...
I'm new using access...
I have a simple database (made just for practice) with a number of tables. It's supposed to be a "Library usage database", with tables for books, lenders, cities etc.
For instance, the table "Lenders" is a table with..well.. people loaning books from the library. It has among other things a column "City" which is a Foreign Key (right?) that references to the table of Cities.
Now, I would like a form to add lenders. However, for "cities" I would like a control/ list box/ drop down box that displays the cities already entered (displayed by name). When I select a city in that list, the corresponding ID-number is set in the "Lenders" table.
Is there a (fairly) simple way to do this. I've experimented with subforms and list boxes, but not quite found a way to do this.
I am trying to work around a limitation that Filemaker 12 seems to have. In a value list that links to an ODBC attached SQL Server database, it doesn't display every piece of data. If there are 2 people with the same last name for example, it only displays the first person with that last name in the list. This is verified by the following in the Filemaker documentation (which I found after a lot of digging)
If the value list is defined to display information from two fields, items will not be duplicated for the field on which the value list is sorted. For example, if the value list displays information from the Company field and the Name field, and if the values are sorted by the Company field, only one person from each company will appear in the value list.
Portals on the other hand will find all the related data, I just don't understand how do something with the data once I get it in the portal. I essentially thus wish to use a portal AS my drop-down value list, and then to use it as I would have a value list (which is then to act as the key to do the rest of the lookups on the page to fill out the invoice.
The major issue here (other than this maddening choice Filemaker seems to make) is that the external file I am pulling the data from is an ODBC mounted SQL Server file, so I can't do something easy like a calculated field which would give me last name & " " & first which would make almost every person unique. Filemaker won't let me do that because it says I can't do that with a field that is not indexed. Any help would be greatly appreciated!
Assuming that we're starting with table MyTable and we're trying to get a ID from the People table for the selected person, which we'll call ID so that we can put it into MyTable::PersonID
Start by creating a new Table Occurrence of your People table and call it PeopleWhoCanBeSelected. If you want every person in the People table you can connect it to MyTable with the X relationship. If you want to show just a subset of the people you can build a different relationship.
Now, on a layout displaying records from MyTable you will make a portal showing records from the PeopleWhoCanBeSelected table.
In the portal put a button. When that button is pressed use the Set Field script step:
Set Field MyTable::PersonID to:
PeopleWhoCanBeSelected::ID
That should do it. You can make the button an invisible overlay on the entire portal record if you like, so that the user clicks on "the name" instead of "the button next to the name".
Now, if you want to pull additional data through to the MyTable record, you'll need to create a second Table Occurrence, called People with the relationship MyTable::PersonID = People::ID. Then you can get information on the specifically chosen person through that relationship.
