JOIN QUERIES
TIP #1
• Joins are useful for creating relationships between queries that may not exist in the model
• The Join in the model may not the same as the join you require
• For example, the Model contains an inner join and you require an outer join
• You can create a series of joined queries

REFERENCE DATA IN A SEPARATE QUERY
TIP #2
• Useful when filtering data in just one filter would exclude too much data
• Instead, create one query that filters out the relevant data and then create a second query that references the first query’s result set.
• Filtering Query 1 by the result set of Query 2 will produce a report that shows only orders with a specified product and of those orders only products that have generated a lifetime revenue of over $5,000,000.
FILTERING QUERY DATA FROM ANOTHER QUERY
Query 1
Order, Product Revenue
Filtered to include
Only orders with a specified Product
Query 2
Product and revenue
Filtered to only include products that
Have generated over $5,000,000

• Eliminate multiple versions of the same report

LAYOUT COMPONENT REFERENCES
TIP #4
• The Layout Component Reference Object allows authors to reference objects within and across reports
• Any Layout object with its Name property populated can be referenced
• Queries can NOT be referenced
• Overrides are available for Parent-Child objects

ADVANCED EXPRESSIONS
TIP #5
• Remember that only Query Calculations will give you access to the Query Engine, so
• Best Practice: build advanced expressions modularly from within the Query, even if you don’t plan to display them
