    • HIVE-187. Preliminary ODBC Support. (Eric Hwang via rmurthy)
    • ODBC

    Description

      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.
