Julian Hyde created CALCITE-4591:
------------------------------------
Summary: RelRunner should throw SQLException if prepare fails
Key: CALCITE-4591
URL: https://issues.apache.org/jira/browse/CALCITE-4591
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
{{interface RelRunner}} allows statements to be prepared from a {{RelNode}}
tree rather than via SQL. A {{RelRunner}} is typically obtained from a JDBC
connection, by calling {{connection.unwrap(RelRunner.class)}}. As such,
{{RelRunner}} is an extension to the JDBC driver, and therefore the
{{RelRunner.prepare(RelNode)}} method should throw {{SQLException}}, rather
than {{RuntimeException}} as it does today.
This change adds a new method
{code}
PreparedStatement prepareStatement(RelNode) throws SQLException
{code}
and marks the current {{prepare}} method as deprecated. (As {{RelRunner}} is
marked "experimental", we could have removed or changed the old method without
notice, but chose not to.)
