Subject [jira] [Commented] (CASSANDRA-4242) Name of parameters should be available in CqlPreparedResult
Date Tue, 15 May 2012 21:27:08 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13276232#comment-13276232

Jonathan Ellis commented on CASSANDRA-4242:
-------------------------------------------

bq. I need this to bind parameters from various data source (which expose unordered named
values)

Well, yes, it's definitely designed around data sources that give you ordered values instead.
This fits at the least JDBC, Python DBAPI, and Ruby DBI.  What are you using that can't work
with this paradigm?

> Client side, it could be nice to have the name of parameters in CqlPreparedResult. This
could allow parameters mapping by name instead of by index.
