Description

SqlDialect is used by the JDBC adapter to generate SQL in the target dialect of a data source. SqlParser.Config is used to set what the parser should allow for SQL statements sent to Calcite. But they both are a representation of "dialect". And they come together when we want to use a Babel parser to understand SQL statements that are meant for a data source.

So it makes sense to integrate them, somehow. We could add a method

void SqlParser.ConfigBuilder.setFrom(SqlDialect dialect)

or do it from the other end,

SqlDialect.configureParser(SqlParser.ConfigBuilder configBuilder)
