Function lineageWithSchema

lineageWithSchema(
    column: string,
    sql: string,
    schema: Schema,
    dialect?: string,
    trimSelects?: boolean,
): LineageResult
Trace the lineage of a column through a SQL query using schema metadata.

When a schema is provided, columns are fully qualified and type-annotated. Each LineageNode.expression will have its inferred_type field populated with the resolved SQL data type. Use ast.getInferredType(node.expression) to read it.
Parameters
- column: string
  Column name to trace
- sql: string
  SQL string to analyze
- schema: Schema
  ValidationSchema-compatible schema object
- dialect: string = 'generic'
  Dialect for parsing/qualification (default: 'generic')
- trimSelects: boolean = false
  Trim SELECT to only target column (default: false)
Returns LineageResult
Example
```
import { lineageWithSchema, ast } from '@polyglot-sql/sdk';

const result = lineageWithSchema("name", "SELECT name FROM users", {
  tables: { users: { name: "TEXT", id: "INT" } }
});

if (result.success) {
  const dt = ast.getInferredType(result.lineage!.expression);
  // dt => { data_type: "text" }
}
```
