Eric Hwang commented on HIVE-187:
---------------------------------
Hi all,
The ODBC driver that I am now working on supports most of the basic ODBC
functionality for connecting, executing queries, and fetching results. The
build process is proving to be a little more complicated because the driver was
developed using the unixODBC framework, which cannot be committed into the
apache repo, but I'll see if I can include it as an attachment to this JIRA. If
all goes well, I should have a patch up by the end of this week. Thanks for
waiting guys.
Regards,
Eric

> Key: HIVE-187
> URL: https://issues.apache.org/jira/browse/HIVE-187
> Project: Hadoop Hive
> Issue Type: New Feature
> Components: Clients
> Affects Versions: 0.2.0
> Reporter: Raghotham Murthy
> Assignee: Eric Hwang
> Fix For: 0.4.0
>
>
> We need to provide the a small number of functions to get basic query
> execution and retrieval of results. This is based on the tutorial provided
> here: http://www.easysoft.com/developer/languages/c/odbc_tutorial.html
>
> The minimum set of ODBC functions required are:
> SQLAllocHandle - for environment, connection, statement
> SQLSetEnvAttr
> SQLDriverConnect
> SQLExecDirect
> SQLNumResultCols
> SQLFetch
> SQLGetData
> SQLDisconnect
> SQLFreeHandle
>
> If required the plan would be to do the following:
> 1. generate c++ client stubs for thrift server
> 2. implement the required functions in c++ by calling the c++ client
> 3. make the c++ functions in (2) extern C and then use those in the odbc
> SQL* functions
> 4. provide a .so (in linux) which can be used by the ODBC clients.
