Which Versions of XML Schema Does Liquid Data Support?
How Can I Learn More About the XQuery Language?
What is the Data View Builder?
Key Concepts of Query Building
Different Kinds of Data Sources

4. Query Parameters: Submitted at Query Runtime
5. Query Results - Large Results
To Make a Project Portable, Save Target Schema to Repository
Saving a Project is Not the Same as Saving a Query
Special Characters: Occurrence Indicators
Next Steps: Building and Testing Sample Queries
Opening the Source Schemas for the Data Sources You Want to Query
Mapping Source and Target Schemas
Example: Query Customers by State
Supported Mapping Relationships
Using Constants and Variables in Functions
Adding or Deleting Parameters in a Condition Statement
Exceptions to Automatic Type Casting
Example: Return Customers by Name
View the XQuery and Run the Query to Test it
Example: Query Customers by ID and Sort Output by State
Open the Data Sources and Add a Target Schema
Map Nodes from Source to Target Schema to Project Output
Specify the Order of the Result Using the Sort By Features
View the XQuery and Run the Query to Test it
Understanding Scope in Basic and Advanced Views
Basic View (Automatic Scope Settings)
Advanced View (Setting the Scope Manually)
When to Use Advanced View to Set Scope Manually
Task Flow Model for Advanced View Manual Scoping
Saving Projects from Basic or Advanced View
Understanding Query Design Patterns
Target Schema Design Guidelines and Query Examples
Examples of Effective Query Design
Why is source replication necessary?
When is source replication necessary?
When should you manually replicate sources?
Using the Features on the Optimize Tab
Example: Source Order Optimization
Using Parameter Passing Hints (ppleft or ppright)
Specifying Large Results for File Swapping
