class  pixeltable.serving.SqlExport

• db_connect (Any): SQLAlchemy connection string for the target database (e.g. 'postgresql+psycopg://user:pw@host/db', 'sqlite:///path/to.db').
• table (Any): Name of the target table. It must already exist; resolution fails if the table is missing.
• db_schema (Any): Optional database schema qualifier (e.g. 'analytics'); leave None to use the connection’s default schema.
• method (Any): How to write each row into the target table.
  • 'insert': append the row via INSERT ... VALUES.
  • 'update': update the row by primary-key match (UPDATE ... SET ... WHERE pk=...). Requires that the target table has a primary key whose metadata is exposed by the dialect. The exported columns must include all primary-key columns of the target plus at least one non-PK column to set. This is a strict update, not an upsert: if the WHERE clause matches zero rows, the export fails. Useful when the source is append-only but the target is a deduplicated current-state view.
  • 'merge': upsert via the target table’s primary key. Currently not supported.
