ODBC Driver for SAP BusinessObjects BI

Build 21.0.7930

Querying Data

After Connecting, you can allocate a statement handle and execute the statement.

SELECT Procedure

Use SQLExecDirect to execute the statement and SQLFetch to fetch the records. You can use SQLBindCol to bind variables to columns in the result set. The numbering of the result set columns starts at 1.

SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv); 
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc); 
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"Dsn=CData SAPBusinessObjects~ Source", SQL_NTS, 0, 0, 0, 0);
SQLAllocHandle(SQL_HANDLE_STMT, hdbc, &hstmt);
SQLExecDirect(hstmt, (SQLCHAR*)"SELECT Column1 FROM MyCustomReport WHERE Column2 = 'Bob'", SQL_NTS);  
SQLCHAR sColumn1[20] = {0};
SQLLEN cbColumn1 = 0;
SQLBindCol(hstmt, 1, SQL_C_CHAR, sColumn1, 20, &cbColumn1);
SQLRETURN retcode = SQLFetch(hstmt);
if (retcode == SQL_SUCCESS || retcode == SQL_SUCCESS_WITH_INFO) {
 ...
}

Iterating over the Results

You can use SQLGetData to get values while iterating through a cursor. To iterate over the results, use SQLFetch to fetch rows and SQLGetData to retrieve the column values.

  SQLHENV henv;
  SQLHDBC hdbc;
  SQLHSTMT hstmt;
  char sStoreName[255] = {0};
  SQLLEN cbId = 0;
  if (SQLAllocHandle(SQL_HANDLE_ENV, 0 ,&henv) == SQL_SUCCESS) {
    SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
    if (SQLAllocHandle(SQL_HANDLE_DBC, henv ,&hdbc) == SQL_SUCCESS) {
      if (SQLConnect(hdbc, "CData SAPBusinessObjects~ Source", SQL_NTS, 0, 0, 0, 0) == SQL_SUCCESS) {
        if (SQLAllocHandle(SQL_HANDLE_STMT, hdbc ,&hstmt) == SQL_SUCCESS) {
          if (SQLExecDirect(hstmt, "SELECT StoreName FROM MyCustomReport WHERE Column2 = 'Bob'", SQL_NTS) == SQL_SUCCESS) {
            while(SQLFetch(hstmt) == SQL_SUCCESS) {
              if (SQLGetData(hstmt, 1, SQL_C_CHAR, (SQLPOINTER)sStoreName, 255, &cbId) == SQL_SUCCESS) {
                printf("StoreName: %s\n", sStoreName);
              }
            }
          }
          SQLFreeHandle(SQL_HANDLE_STMT, hstmt);
        }
        SQLDisconnect(hdbc);
      }
      SQLFreeHandle(SQL_HANDLE_DBC, hdbc);
    }
    SQLFreeHandle(SQL_HANDLE_ENV, henv);
  }
