Subject Errors querying Sybase databases using RDBMS plugin
Date Thu, 12 May 2016 22:54:55 GMT
Hi all:

I set up a Sybase ASE DB using the RDBMS storage plugin.  Using show
schemas and show tables I can see the schemas and tables.  However, when I
do a query, it's adding the schema name in the query and apparently Sybase
doesn't like it.  For example:

0: jdbc:drill:zk=local> select count(*) from dbfs_user;

Error: DATA_READ ERROR: The JDBC storage plugin failed while trying setup
the SQL query.



sql SELECT COUNT(*) AS "EXPR$0"

FROM (SELECT 0 AS "$f0"

FROM "kozo_analytics"."dbfs_user") AS "t"

plugin sybase

Fragment 0:0

  (java.sql.SQLException) "kozo_analytics"."dbfs_user" not found. Specify
owner.objectname or use sp_help to check whether the object exists (sp_help
may produce lots of output).

If I try that same query directly using a query tool I get the same error.
I've tried all the combinations of use and select including/excluding the
schema name and it either says the table doesn't exist, or it includes the
schema name and Sybase complains.  Is there a way to disable including the
schema name in the query?


I also set up a Sybase IQ database using the RDBMS plugin.  When I try to
query any table I get this error:

0: jdbc:drill:zk=local> select count(*) from collat_history;

Error: VALIDATION ERROR: Multiple entries with same key:
IssuerHist=JdbcTable {IssuerHist} and IssuerHist=JdbcTable {IssuerHist}



SQL Query null

Any ideas?
