AQL Fundamentals

• AQL Syntax explains the structure of the AQL language.
• Data Types describes the primitive and compound data types supported by AQL.
• Bind Parameters: AQL supports the usage of bind parameters. This allows to separate the query text from literal values used in the query.
• Type and value order: AQL uses a set of rules (using values and types) for equality checks and comparisons.
• Accessing Data from Collections: describes the impact of non-existent or null attributes for selection queries.
• Query Results: the result of an AQL query is an array of values.
• Query Errors: errors may arise from the AQL parsing or execution.
• Limitations: known limitations for AQL queries.
