The Signups data table is the join table. Each student signs up for multiple classes and each class can have multiple students.

The Import Field Mapping dialog displays the incoming field names on the left and the field names of the active FileMaker Pro database on the right. This setup also supports the previous capability of having one Customer linked to multiple Forms.Īnother common example of a join table use is a school with Students, Signups and Classes. In the Open File dialog box, choose the name of the file that contains the data you wish to import (the source file), and click Open. This example imagined above might be appropriate where two Customers are from the same family and they share a single form.
The remote data can be modified in FileMaker Pro and tables can be used in the relationships graph like standard FileMaker Pro tables.

ESS: Instead of working with a local copy of the data, you can use the JDBC driver to create an external SQL source. More than one Customer record can be linked to a single form. To use this approach, see ODBC SQL Server Integration in FileMaker Pro.
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.”Īdding a Join table between the two existing tables allows the possibility of linking multiple records to the same record. 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. Each record in the “join table” would have the foreign key fields of the two tables it is joining together.
Using a third table, commonly called a “join table”, does this. To get around the problem of having a many-to-many relationship you need to break apart the many-to-many relationship into two one-to-many relationships. If there were “many” invoices with the same invoice number and one of your many customers called up asking about that invoice number how would you know which specific one they were referring to? The answer is you could not. Consider the example of keeping track of invoices. According to FileMaker’s Help page on Join Tables, “In relational database design, a many-to-many relationship is not allowed.
