Querying Oracle DB from Revolution R using RODBC -


Revolution R 64 on

connected to winxp64 bit oracle using a 64 bit ODBC driver via a DSN

Bit RODBC error 
  library (RODBC) database & lt; - (c_RODBCFetchRows, attr (channel, or 'c'), in the call ("oraclemiso", uid = "epicedf", public construction department = "...") ("count select (*)" db from FTRAuction) Negative length vectors are not allowed

But when I connect to the stuff, I'm also doing a problem to get an error, "handle_ptr"), Max, buffsize, Works 

  Library (RODBC) channel & lt; - odbcConnect ("OraLSH", & lt; user & gt;, & lt; password & gt;)) odbcQuery , "Choose sysdate from double") sqlGetResults (channel , As.is = FALSE, errors = FALSE, max = 1, buffsize = 1, nullstring = NA, na.strings = "NA", trustNRows = true, December = getOption ("Dec") SYSDATE 1 2010- 01- 24 15:10:02

But if I do not know the rows (max = 1) before hand

thanks, Arun

trust = = FALSE key appears when opening the connection best to use it:

db & Lt; - odbcConnect (DSN = "testdsn", uid = "testuser", Public Works Department = "testpasswd", believeNRows = false)

When unixODBC is tested with isql, then This is the SQLRowCount 4294967295 (even if only one line) on 64 bit linux, while it reports 1 on 32 bit Linux. This is probably an optimization because it enables fast answers, it saves the burden of recovering the complete response data to the database immediately. Just like there will be lots of records while there will be only a few hits ever to be brought.

4294967295 (2 ^ 32) -1 which is the maximum value for an unsigned integer, but as -1 will be tretated with a signed int thus r negative length on a vector Complains with So I think this is an issue about signed Vs signed integer (or between sizes 32 and 64 bit).

believeNRows installation = FALSE If the problem for me is resolved, then I can use the same R code on both systems

Btw:. I am using R 2.10.1, UnixODBC 2.3.0 with RODBC 1.3.2, Linux 64 bit Oracle 10.2.0.4. Be sure to use

Export CFLAGS = "- DBUILD_REAL_64_BIT_MODE -DSIZEOF_LONG = 8 -fshort-wchar"

When doing the Oracle ODBC driver as unixODBC Required REAL_64_BIT_MODE, not LEGACY_64_BIT_MODE

and aware of internationalization issues: R $ uses LANG, while Oracle uses $ NLS_LANG

I have a UTF8 Experiencing problems so I use like.

lang = en_US; NLS_LANG = American_America

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....

wpf - Custom Message Box Advice -

Well, I'm using a custom window box that comes with some custom control boxes that accompany the text The producers who are displayed are called. I have a defined event, which has been subscribed through the original class, it gets burnt when clicking on the button. However, I can not see how to use it effectively, I would like to return one yes, whether yes or not, but obviously my code will continue to execute, so this Below is some example code to clarify the problem that the method has subscibed by clicking on the button. Message box window Public partial class custom message box: window {public representative message messagebox object sender, event events e); Public event messagebox handler messagebox document; Public Customs Box () {Initial group (); } Public Customsbox (String Message) {InitializeComponent (); This.txtdescription.Text = Message; } Public Customsbox (String Message, String Title, String First BTNtext) {Initialization (); This.lbltitle.Content =...
