2. Overview SQL Functions as Informer Properties SQL Properties and Links
Types of Links
SQL Criteria
Multi-value View

3. SQL Functions
Pre-existing SQL functions can process fields and output them as new Informer fields
Useful for multi-part joins

4. SQL Properties Every table has a primary key
Primary keys from one table can exist as foreign keys in a secondary table

5. What are links? Links define a relationship between two fields
Either direct…
Or via a third table…
ADDRESS ID
STATE
ZIP
PERSON ID
NAME
COMPANY ID
COMPANY ID
ADDRESS ID

6. Creating a Link
Mappings -> [Datasource] -> [Table] -> Links

7. Creating a Direct Link
Associate one table directly to the fields in a secondary table

8. Creating a Link via a Third-Table
Associates one table to another, via a third “collection table”

9. Creating a Scalar Link
Allows users to create a JOIN between two tables that will only bring back a specific sub-set of data

10. Embedded Links
Configures the link so that all “child” fields appear within the “parent” table
Happens both when adding columns and selecting filters

11. Embedded v. Not Embedded

12. Aggregate Conditions Aggregate Columns and Conditions
Performs a SQL Aggregate function on the desired column
Has an impact on performance due to server-side calculation
Allows you to group on the column that the aggregates are performed on

13. Aggregate Conditions
First create an Aggregate column, then an Aggregate filter

14. Aggregate Conditions
Results in:

15. Sub-selects
Should start in one table that links to a secondary table with a one-to-many relationship
Useful for finding specific values in a dataset
For example…
Finding a list of non-returning students, or students present enrolled during Fall 2005, but not Spring 2006

16. Sub-selects
Starts with…

17. Sub-selects
Filter 1…

18. Sub-selects
Filter 2…

19. Sub-selects
Finalized filters…

20. Sub-selects
Ends with…

21. Multi-value View
Allows users to select and “collapse” the non-unique data contained in a single column

22. Multi-value View
After enabling multi-value view on the ID STUDENT, First Name, and Last Name
