    [ https://issues.apache.org/jira/browse/CALCITE-3381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16941181#comment-16941181 ] 

Julian Hyde commented on CALCITE-3381:
--------------------------------------

> 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.
