Julian Hyde created CALCITE-4087: ------------------------------------ Summary: Hoist, a utility to replace literals in a SQL string with placeholders Key: CALCITE-4087 URL: https://issues.apache.org/jira/browse/CALCITE-4087 Project: Calcite Issue Type: New Feature Components: babel Affects Versions: 1.23.0 Reporter: Julian Hyde
Add "Hoist", a utility to replace literals in a SQL string with placeholders. By default it uses Calcite's parser, but you can configure to use different quoting, casing, and also to use a different parser such as Babel for other dialects of SQL. It generates a data structure, {{Hoisted}}, that contains a map of where the literals occur within the SQL string. The Hoisted.substitute method generates an alternative SQL string, replacing the literals with a custom string. It does not call {{SqlNode.unparse}}, and therefore does not lose any of the original formatting. For more examples, see tests added to {{SqlParserTest}} and {{BabelParserTest}}. -- This message was sent by Atlassian Jira (v8.3.4#803005)
