[jira] [Commented] (PHOENIX-6665) PreparedStatement#getMetaData() fails on parematrized "select next ? values for SEQ"

["Istvan Toth (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-6665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17504824#comment-17504824 ] 

Istvan Toth commented on PHOENIX-6665:
--------------------------------------

Avatica uses this for every preparedQuery.

Consequently, the above query fails via PQS, even without explicitly calling nextStmt.getMetaData().

> Because a {{PreparedStatement}} object is precompiled, it is possible to know about the {{ResultSet}} object that it will return without having to execute it. Consequently, it is possible to invoke the method {{getMetaData}} on a {{PreparedStatement}} object rather than waiting to execute it and then invoking the {{ResultSet.getMetaData}} method on the {{ResultSet}} object that is returned.
