The Join Options tab is used to create joins.
The following image shows the Join Options tab with an existing join selected.
Use the drop-down list to select the join with which you want to work.
Click to delete the join.
Click to create a new join.
Join Settings:
Enter a description for your join.
WebFOCUS assigns an alphanumeric name for the join, for example J001.
This option is selected in the Join properties when a join that was created in an earlier release is opened. In prior versions, the defaults for join type and other operators were assumed and not specified in the generated code. Since the HTML Graph Assistant cannot determine the type of join that was created and if there were other commands set to control the join, select the appropriate options (Inner Join, Left Outer Join, Multiple Instances, Single Instances) from to upgrade the generated code.
A join that results when a report omits host rows that lack corresponding cross-referenced rows.
Extends the results of an Inner Join and retrieves records from both host and cross-referenced tables, including all records from the left table (host) and any records from the right table (cross-referenced) where the condition values match. If there are no matching values in the cross-referenced table, the join still retrieves records from the host table.
A one-to-many join structure that matches one value in the host data source to multiple values in the cross-referenced field. Joining employee ID in a company's employee data source to employee ID in a data source that lists all the training classes offered by that company would result in a listing of all courses taken by each employee, or a joining of the one instance of each ID in the host file to the multiple instances of that ID in the cross-referenced file.
A one-to-one join structure that matches one value in the host data source to one value in the cross-referenced data source. Joining an employee ID in an employee data source to an employee ID in a salary data source is an example of a unique join.
Once you have selected your host and target fields, click Save & Create to create the join.
Click to view the syntax of your join, which displays the code sent to the WebFOCUS Reporting Server to validate the join, but may not be the same code required to run the report. This is the case for a DEFINE based JOIN where only the JOIN statement is displayed for validation, but both the JOIN and DEFINE statements are needed when the report is run.
Click the Define icon to select: New define field, Edit define field, or Delete define field. If you select the New define field or Edit define field, the Define field creator dialog box opens where you can create or edit a defined field.
Displays a tree structure of field names by segment with, segment, alias, title, description, and format information below the tree. Individual field information appears when you click on the field.
Displays a list of all field names with information that you select from the adjacent arrow that opens a drop-down list: name, alias, title, remarks, format, description, segment, and file name. You can also choose to sort by file order.
