Using conditional joins, you can establish joins based on conditions other than equality between fields. In addition, the host and cross-referenced join fields do not have to contain matching formats, and the cross-referenced field does not have to be indexed.
The conditional join is supported for FOCUS and all relational data adapters. Because each data source differs in its ability to handle complex conditional criteria, the optimization of the WHERE syntax differs depending on the specific data sources involved in the join and the complexity of the conditional criteria.
Joining Tables
...
InfoAssist users can join two or more related data sources (also referred to as tables) to create a larger pool of fields. The joined structure is a virtual way of accessing multiple data sources as if they were a single data source.
Joining Tables
Open an existing report or create a new report.
If creating a new report,
open the first table of data.
Note The first table you select cannot be changed in a report
.
Once the correct table is selected, click Open.
- From within the report, click
Click the Data tab, and then click Join
, from the ribbon.
- From
In the Join dialog box, click Add New.
- From
In the Open dialog box, select a second table.
Click Open.
NoticeNotice the Join dialog box will display with two tables at this point.
Identify the common field of data in both tables.
ForFor example, EMPLID is the common field of data found in both tables used in the screenshots of this documentation.
Left-click the field name in the first table and hold to ensure the data remains selected.
Drag the selected data to the second table, releasing the left-click once the data from the first table is over the matching field name of data in the second table.
Notice the arrow between the two tables, indicating the join is successful.
LeftLeft-click in the middle of the arrow
,to change the
arrowsarrow's color to red.
Right-click in the middle of the red arrow to display a menu of options.
Click Edit from the list of available options.
From the Edit Join dialog box, confirm the selections from the Instances and Type dropdown menus are accurate for your Join.
Note NOTE - The Instances dropdown options – Single - will go for a single match. If you there are multiple instances of the specific data in the tables, select multiple to instruct the join to search the second table of multiple instances of that value. The Type dropdown options Default - gets all rows in all tables. Inner gets all rows that exists in both tables. Left Outer - goes through first data, produces complete list of data, then goes through second table to see if there is matching data.
For example, select Inner, from the Type dropdown to get..... if you select Outer Left from the Type dropdown to get..... select Default from the Type dropdown to get..... ← Jean to add specific examplesClick OK.
To confirm your two tables have been joined, navigate to the left data pane from the main report view.
Click the arrow to expand the list of field names in the first table.
Scroll down to the bottom of the left data pane to locate the second table.
ClickClick the arrow to expand the list of field names in the second table.
To build the report, select the appropriate field(s) from either table,
thenand drag the field(s) to the appropriate quadrant.
Tip
To add additional tables to this join, repeat the steps above at any point in the process.
