[jira] [Comment Edited] (DRILL-3198) JDBC driver returns null DatabaseMetaData#getTypeInfo()

    [ https://issues.apache.org/jira/browse/DRILL-3198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14577589#comment-14577589 ]

For reference, the following methods currently return null rather than a ResultSet representing a zero-row result set:
- getAttributes
- getBestRowIdentifier
- getClientInfoProperties
- getColumnPrivileges
- getCrossReference
- getExportedKeys
- getFunctionColumns
- getFunctions
- getImportedKeys
- getIndexInfo
- getPrimaryKeys
- getProcedureColumns
- getProcedures
- getPseudoColumns
- getSuperTables
- getSuperTypes
- getTablePrivileges
- getTableTypes
- getTypeInfo
- getUDTs
- getVersionColumns

>          Components: Client - JDBC
>    Affects Versions: 1.0.0

> JDBC driver returns null from DatabaseMetaData#getTypeInfo() instead of a ResultSet, causing some client tools to throw NPEs.
> Driver works with SquirrelSQL (http://drill.apache.org/docs/using-jdbc/), but fails with others (DbVisualizer for example).
