             Summary: Add `getCastSpec` for BigQuerySqlDialect
                 Key: CALCITE-3381
                 URL: https://issues.apache.org/jira/browse/CALCITE-3381

          Issue Type: New Feature
          Components: core
    Affects Versions: 1.21.0
            Reporter: Kirill Kozlov


When using `SqlImplementor.SimpleContext#toSql` with BigQuerySqlDialect on Rel nodes containing `CAST` need to convert Calcite SqlTypeName to BigQuery supported types ([https://cloud.google.com/bigquery/docs/reference/standard-sql/data-types]).

Example: VARCHAR should become a STRING, BOOLEAN - BOOL, and so on.
