Query Execution Order

Concepts: sqlExecutionOrder

Understanding Execution Order Walk through this example to see how the CTE executes before the outer query, not after it. Basic Example This example shows how a CTE executes first to filter logs, then the outer query applies an additional filter on the result. The CTE executes first to produce the temporary dataset. The outer query then filters from it. Practical Implications Understanding execution order helps you avoid common pitfalls like referencing aliases before they exist. Real-World Example When working with device logs, intermediate results must exist before applying filters or aggregations. Ignoring execution order can lead to errors or incorrect results. Understanding the sequence of execution ensures each step behaves correctly and can be reused for other tasks. Here is the ful
