The following image shows the Join Options tab with an existing join selected.

Existing join options

Select an existing join: Use the drop-down list to select the join with which you want to work. x
Delete: Click to delete the join.
New: Click to create a new join.

Join Settings:

Description: Enter a description for your join.
Internal name: WebFOCUS assigns an alphanumeric name for the join, for example J001.
Unspecified: Select from the Join Types drop-down list to indicate neither an inner or left outer join.
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 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.
Inner Join: A join that results when a report omits host rows that lack corresponding cross-referenced rows.
Left Outer Join: 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.
Multiple Instance (formerly Non Unique): 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 the employee data source, of your company, 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.
Single Instance (formerly Unique): 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. x
Save & Create: Once you have selected your host and target fields, clickSave & Create to create the join. x
View: 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.
