Many to Many relationship I have two databases: one is Books when I link the relationship to the particular sequence field (Title Record ID While the field list is active, use the up- and down-arrow keys to select the FileMaker provides many ways to add a field to a layout, all of which require you to. After you have created a relationship, you can add or change match fields, change For self-joining relationships, locate the single table; FileMaker Pro will .
In Windows, an arrow to the right of the tool lets you view the pop-up menu. To add the Lease Value field to the layout, follow these steps: When you move your cursor down to the work area, it changes to crosshairs. Click in the layout and drag to create a new field. As you drag, FileMaker shows dynamic guides to help you size and line up the field.
When the field is the size you want, release the mouse button.
When you add a field to the layout, FileMaker asks which field you want by showing you the Specify Field dialog box. Another way to quickly create a field with the formatting you want already on it is to copy and paste an existing field and its label.
Double-click the new field to show the Specify Field dialog box. The field and its label appear on the layout. Most people prefer to see currency data aligned to the right. You can do that in one of three ways: The Date Signed field is also wider than it needs to be, so switch back to Layout mode and make it a little smaller as well, but not quite as narrow as your currency fields.
Deleting a Field In the Manage Database window, you can delete a field and its contents in all records of the current table by selecting it and then clicking Delete. Calculation fields like Lease Value make reference to other fields.

If you try to delete either Lease Duration or Rental Fee, FileMaker shows you a warning dialog box and refuses to delete the field. If you absolutely, positively have to delete either field, you have a choice: But in that case, you get the choice to proceed anyway or cancel the delete. If you delete a field used in a script, be prepared to do some repair work.
Worse yet, for your and month leases, most of those fields will be empty. And what if your tenants make more than one payment each month?
You need separate tables to store each type of information. What you need is a new Payment table, where you can add 12 records one per month, of course to the month leases, or 24 records to the month leases.
FileMaker lets you put dozens, even hundreds, of tables into the same file. Finally you create a special layout object, called a portal, that lets you view, create, and edit records from a related table. A database is a collection of tables, layouts, and other features that form an organized system. A table holds information about one kind of thing, like the two tables in your database: Another database might have four tables: Each table is like a single worksheet in a spreadsheet program.
A field holds one bit of information about something: A record is the collection of data a set of fields in a table that describes one unique thing. An attribute is an individual characteristic. For example, a bicycle might have several attributes: In a database, each of these attributes gets its own field. An entity is one kind of thing. Each entity People gets one table in a database and each instance of an entity Steve Jobs gets one record in that table.
A key field uniquely identifies each record so that each related record knows which record it matches, like an Employee ID Number for a person. A relationship describes how the records in two tables match each other Understanding Relational Databases.
The most common relationships are called parent-child relationships.
So in your database, the Lease Agreement is the parent record and each Payment record is a child. In the Field Name field, type agreementID.

In this naming convention, the field name starts with the name or one-word abbreviation of the table for which it is the key field. From the Type pop-up menu, choose Number. Key fields are most often number fields. See Keys for more information on choosing and creating a good key field. Click the Create button and then click the Options button. A serial number is created in the agreementID field for each new record you make. Create a few new records to watch serial numbers being created.
For instance, a user might create a record but then delete it instead of filling out its data. In that case, there would be a gap in the serial numbers, because the numbers assigned to deleted records are never reused. First, find just the records without serial numbers. Click in the agreementID field. The Replace Field Contents window appears. Instead, pressing Enter cancels the replacement and leaves everything as it was. Replace with serial numbers tells FileMaker how you want the numbers created in your existing records.
Serial numbers are created in all the records of your database. Flip through the records to see the serial numbers. Create a new record to see the next value appear automatically in the agreementID field. Tip Because it can be cumbersome to create a key field and populate it with data months or even years later, it makes sense to create a key field in every table you create even if you have no immediate plans to relate the table to any other table.
Creating a New Table Your Payment table needs to store information about each monthly payment for a specific Lease Agreement. You also need a key field for hooking up Payments to the Lease Agreement table. Two key fields in one table? See Primary and Foreign Keys for information on primary and foreign keys. The second key field agreementID will hold the value that matches the value in the key field of a specific record in the Lease Agreement table.

This tab is where you create, edit, and manage your tables. In the Table Name field, type Payment and then click Create. When you created the Lease Agreement table, you decided to use the singular case for your database elements, so stay consistent. The Payment table appears in the Tables list. Click the Fields tab. FileMaker is smart like that and switched to the selected table for you.
But if you need to, you can switch tables using the Table pop-up menu above the list of fields. Click the Options button and make the paymentID field an auto-enter serial number.
All your Payment records will have serial numbers because you created a key field right at the beginning, before you created any records. Protecting the data in a key field is critical to keeping your records properly related to one another. Use the skills you learned earlier in this chapter to create these fields their types are in parentheses: FileMaker created it for you when it created your new table.
When you see this message, just click OK. You could dress this layout up any way you want to. For instance, you might turn it into a list layout so you can report on your payments. Creating a Relationship Between Two Table Occurrences You just saw that when you create a table and then add fields to it, FileMaker makes a bare-bones layout for that table. It also makes a Table Occurrence for the new table on the Relationships graph. Note Your Relationships graph can have more than one instance of any table, and each instance is a different view into the table.
Each instance of a table is called a table occurrence. A word of caution, though: And you create relationships in perhaps the easiest way possible: You drag from one table to another to create a line. You need to draw a line between the agreementID fields in each table, but that field is not visible in the Lease Agreement table occurrence.
Click and hold the tiny triangle at the bottom of the Lease Agreement table occurrence. That scrolls the field names so that you can see the one you need.
Or you can drag the bottom border of the table occurrence to make it tall enough to show all its fields. In the Lease Agreement table occurrence, click the agreementID field and then drag to the agreementID field in the Payment table occurrence.
As you hover over any field, it highlights. Double-click the box in the middle of the relationship line. The window is divided into halves, showing Lease Agreement on the left and Payment on the right. Click OK until you return to the Lease Agreement layout. But how does FileMaker know which is which? In a large or complex database, some tables can have many key fields for relating to other tables. Turn to Understanding Table Occurrences to find out why.
The Edit Relationship window lets you define how a relationship works. To change the display, close the Edit Relationship dialog box and then drag the table occurrences to rearrange them. Creating and Using Portals Once your tables are related to one another, you can freely display related fields on layouts.
The problem is solved with a portal, which is a layout object that displays multiple records from a related table. Not only can the portal display related records, but you can also use a portal to create, edit, and delete related records. Adding a Portal to a Layout A portal can display as many related records as you want, limited primarily by the size of your layout and the height of the portal.
As with other layout objects, you can format portals to match your database, using fills and lines the way you would with other drawn objects.
In Layout mode, drag the bottom edge of your Body part to make room for your portal. Or use the Inspector to make the Body points high. In the upper right of the Status toolbar, you see the Portal tool selected. On the layout you can see an outline where the portal will be when you finish creating it. Click the Portal tool to select it and then drag on the layout to create a portal. When you release the mouse, the Portal Setup window appears.
Each field appears in the list on the right as you move it. Tip Pay attention to the way the field name appears in the available fields list. That is, the field is represented by its table name, followed by a pair of colons and then the field name itself.
In Layout mode, the portal displays information about the data it contains along its lower-left edge. Notice that the Lease Agreement:: We needed a way to link the waivers not just to the parent, but also to the children. One-to-Many Relationship Standard database relationships are created by linking ID numbers between data tables. These fields are referred to as key fields. The image above is an example of a regular database relationship—one record the Customer can be linked to multiple Form records.
In this example a Customer record could be continuously updated with a more current form — One Customer to Many Forms. Consider the example of keeping track of invoices. The answer is you could not. Nothing special needs to be done with the foreign key fields in the join table as they will get populated with data from the other two tables as records are created.
It is not uncommon for a join table to have a lot of records in it — since records are created in the join table as records are created in the two tables it joins. More than one Customer record can be linked to a single form.
Examples This example imagined above might be appropriate where two Customers are from the same family and they share a single form. This setup also supports the previous capability of having one Customer linked to multiple Forms.
