# Class: TableSourceCollector

Defined in: packages/core/src/transformers/TableSourceCollector.ts:36

A visitor that collects all table source names from a SQL query structure.

When selectableOnly is true (default behavior):

• Includes only table sources from FROM and JOIN clauses
• Excludes inline queries, subqueries, and CTEs

When selectableOnly is false:

• Scans all parts of the query including WITH clauses, subqueries, etc.
• Collects all table sources from the entire query
• Excludes tables that are managed by CTEs

When dedupe is true (default behavior), repeated table sources are collapsed by their qualified name; pass dedupe=false to retain duplicates.

For UNION-like queries, it scans both the left and right parts.
