![]() You can also adjust the appearance of the employee lists (details pages) with the Detail page editor. Set up the Detail relation editor properties: select the created query as Detail data source, 'id' as Master field and 'office_id' as Detail field. Open the Page Editor of the 'office' table at the Details tab and follow the Add. To specify a master-detail presentation to be used to display a list of employees related to a selected office, WHERE employee_id =:id AND office_id =:office_id WHERE employee_id =:OLD_id AND office_id =:OLD_office_id VALUES (:id, :office_id ) UPDATE employee_office Update statements INSERT INTO employee_office For this purpose use the Create query button and enter the Specify a query to be a datasource for the master-detail presentation. You need to have Linux/Unix or Windows Web Server installed and PHP 5.Īdd the 'office' table as a datasource using the Add table or view button. Specifying a master-detail presentation for the 'office' tableĮach step will be covered in detail below.Here are the steps involved in the implementation: To see the list of offices and lists of employees assigned to selected offices on one web page, create a PHP script with a master-detail presentation. Office_id int NOT NULL, /* Keys */ PRIMARY KEY (employee_id, office_id ), /* Foreign keys */ CONSTRAINT employee_office_relation_ibfk_1įOREIGN KEY (employee_id ) REFERENCES employee (id ) ON DELETE RESTRICT ON UPDATE RESTRICT, CONSTRAINT employee_office_relation_ibfk_2įOREIGN KEY (office_id ) REFERENCES office (id ) ON DELETE RESTRICT ON UPDATE RESTRICT ) ENGINE = InnoDB ![]() SQL definition of the junction table CREATE TABLE employee_office ( ![]() SQL definitions of the tables are as follows: Table to stand between the two existing tables. In database design, the standard decision of the problem is the breaking of such relationship into two one-to-many relationships and creating a new (junction/link) One employee can work at more than one office and an office can have more than one employee assigned (a many-to-many relationship). Let's see the implementation of such presentation for two entities 'employee' and 'office' where The information represented in this article describes the usage of PHP Generators for: MySQL, Microsoft SQL Server, PostgreSQL, Oracle, SQLite, Firebird, IBM DB2, SQL Anywhere, MaxDB.ĭetail presentations for tables linked by one-to-many relationships are created with PHP Generator Below is a step-by-step explanation of how to create a master-detail presentationįor relationships that are multivalued in both directions.
