feat: Display query units in Pipeline repr#27
Merged
Conversation
Enhance Pipeline.__repr__() to show the internal structure of each query
by displaying its query units (CTEs, subqueries, main query).
Changes:
- Pipeline.__repr__() now extracts and displays unit_ids from query lineage
- Each query shows its components in hierarchical format:
- `main` - main SELECT statement
- `cte:name` - Common Table Expressions
- `subq:N` - Subqueries
- Updated README.md with new repr format examples
Example output:
```
Pipeline(
query1: CREATE TABLE ... WITH sales AS (...
cte:sales
cte:customers
main
query2: CREATE TABLE ...
main
)
```
This makes it much easier to understand query structure at a glance,
especially for complex queries with multiple CTEs and subqueries.
