Sql class
A description of a SQL query as interpreted by this package.
This includes the SQL string to send to the database and known data types for parameters, if any.
Queries can be sent to postgres as-is. To do that, pass a string to Session.prepare or Session.execute or use the default Sql constructor. These queries are not intepreted or altered by this package in any way. If you're using parameter in those queries, you either have to specify their types in the Sql constructor, or exclusively use TypedValue instances in Session.execute, Statement.bind and Statement.run.
Alternatively, you can use named variables that will be desugared by this
package with the Sql.named factory. If you prefer positional variables,
but want to specify their types in text or use a different symbol for
variables (Postgres uses $), you can use the Sql.indexed constructor
instead.
