Daniel Barclay (Drill) updated DRILL-3151:
------------------------------------------
    Description: 
In Drill's JDBC driver, some ResultSetMetaData methods don't return what JDBC specifies they should return.

Some cases:

{{getTableName(int)}}:
- (JDBC says: {{table name or "" if not applicable}})
- Drill returns {{null}} (instead of empty string or table name)
- (Drill indicates "not applicable" even when from named table, e.g., for  "{{SELECT * FROM INFORMATION_SCHEMA.CATALOGS}}".)

{{getSchemaName(int)}}:
- (JDBC says: {{schema name or "" if not applicable}})
- Drill returns "{{\-\-UNKNOWN--}}" (instead of empty string or table name)
- (Drill indicates "not applicable" even when from named table, e.g., for  "{{SELECT * FROM INFORMATION_SCHEMA.CATALOGS}}".)

{{getCatalogName(int)}}:
- (JDBC says: {{the name of the catalog for the table in which the given column appears or "" if not applicable}})
- Drill returns "{{\-\-UNKNOWN--}}" (instead of empty string or table name)
- (Drill indicates "not applicable" even when from named table, e.g., for  "{{SELECT * FROM INFORMATION_SCHEMA.CATALOGS}}".)

{{isSearchable(int)}}:
- (JDBC says:  {{Indicates whether the designated column can be used in a where clause.}})
- Drill returns {{false}}

{{getColumnClassName(int}}:
- (JDBC says: {{the fully-qualified name of the class in the Java programming language that would be used by the method ResultSet.getObject to retrieve the value in the specified column. This is the class name used for custom mapping.}})
- Drill returns "{{none}}" (instead of the correct class name)
