> Key: CALCITE-3381
> URL: https://issues.apache.org/jira/browse/CALCITE-3381
> Project: Calcite
> Issue Type: New Feature
> Components: core
> Affects Versions: 1.21.0
> Reporter: Kirill Kozlov
> Priority: Minor
>
> 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]).
> I believe this can be accomplished by Overriding BigQuerySqlDialect#getCastSpec method.
> Example: VARCHAR should become a STRING, BOOLEAN - BOOL, and so on.
