Prasad Chakka commented on HIVE-187:
------------------------------------
some comments on the build process
1)Thrift build process:
need to execute bootstrap.sh before configure
make install fails without sudo
2)Unixodbc:
readline issue. Possibly set --enable-readline=no while configuring unixodbc to
avoid this?
need to do ldconfig after unixodbc is installed
3)
'Select * ' and 'explain select ...' crash isql.
haven't finished looking at the code...

> 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
>
> Attachments: HIVE-187.1.patch, thrift_home_linux_32.tgz,
> thrift_home_linux_64.tgz, unixODBC-2.2.14.tgz

>
> 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.
