问题 I have a Shiny app that has a checkbox group input. The user can select multiple inputs. I also have an ODBC connection linked to a database. The process would be that when a user selects items from the check box group, that user input would be part of a string in the sql query to filter the data. UI.R (partial to show example) checkboxGroupInput('Type', 'Type', c( "AX"="AX", "AY"="AY", "AZ"="AZ", "BGB"="BGB", "BT"="BT", "BX"="BX", "BXT"="BXT", "C"="C", "CNT"="CNT")), The column in the table

问题 I am accessing a commercial DB. Via prompt: select PersonCode, PersonDate from CODB.mastertable where PersonCode=42 PersonCode PersonDate ----------- ------------ 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 42 Jan 3 2011 In R: library(RODBC) query <- "select PersonCode, PersonDate from CODB.mastertable where PersonCode=42" connection1 <- odbcConnect("RESDB", uid="userID", pwd="pwdaccess", believeNRows=FALSE)

问题 we hit to an error with RODBC and SqlSave command. We are a bit confused what to do since the same SqlSave command works when data that we are trying to save to Sybase database is small (~under 10.000 rows). When trying to save bigger data (~200.000 rows) saving process starts without any problems but it crashes after few thousand rows is saved. Then we hit to this error message “unable to append to table..” We use this kind of code: library(RODBC) channel <- odbcConnect("linfo-test", uid=

问题 Have anyone tried to use R and Oracle servers? The credientials required for connection are: HOST = somewhere.com PORT = 1525 SERVICE_NAME = someservice USERNAME = user PASSWORD = pass I've tried RODBC: library(RODBC) channel <- odbcConnect("somewhere.com:1525/someservice", uid="user", pwd="pass") But it only gives me these warnings: Warning messages: 1: In odbcDriverConnect("somewhere.com:1525/someservice", uid="user", pwd="pass") : [RODBC] ERROR: state IM010, code 0, message [Microsoft]

问题 I have the following setup: OSX 10.10.2 PostgreSQL 9.4.1 R 3.1.3 This answer as of 2011 says that the easiest approach is to use RpgSQL package. But it is removed from the CRAN repository. RODBC mentioned there is available as source, but it fails to configure: configure: error: "ODBC headers sql.h and sqlext.h not found" ERROR: configuration failed for package ‘RODBC’ I've also found another package, which could help me - RPostgreSQL, but it fails to compile: In file included from RS

问题 With functionality from the RODBC package, I have successfully created an ODBC but receive error messages when I try to query the database. I am using the INFORMIX 3.31 32 bit driver (version 3.31.00.10287). channel <- odbcConnect("exampleDSN") unclass(channel) [1] 3 attr(,"connection.string") [1] "DSN=exampleDSN;UID=user;PWD=****;DB=exampleDB;HOST=exampleHOST;SRVR=exampleSRVR;SERV=exampleSERV;PRO=onsoctcp ... (more parameters)" attr(,"handle_ptr") <pointer: 0x0264c098> attr(,"case") [1]

问题 I'm learning to use Shiny and shiny dashboard and working with a sql database SQL-SERVER where I'd like to pull the data straight from the database. Essentially the idea is to merge to columns in a table that have a start spot and a stop spot for a date range, tabulate them and then diagram them. I found the following posting on how to pass sql input statements into shiny: How to pass input variable to SQL statement in R shiny? Unfortunately when I try and apply this I get an error 'subscript

问题 I have a 64-bit Windows 7 machine with HANA Client installed and an ODBC connection to an SAP HANA database. In the ODBC Data Source administrator, I have added a connection to the required database and can successfully connect. I am trying to use RStudio to retrieve data for analysis using R. I am finding that queries that return a handful of rows ("TOP 1" to "TOP 17") successfully return all 71 columns of data for the requested number of rows, but when I query with "TOP 18" or higher number

问题 How can I write the argument of select without backtick characters? I would like to do this so that I can pass in this argument from a variable as a character string. df <- dat[["__Table"]] %>% select(`__ID` ) %>% mutate(fk_table = "__Table", val = 1) Changing the argument of select to "__ID" gives this error: Error: All select() inputs must resolve to integer column positions. The following do not: * "__ID" Unfortunately, the _ characters in column names cannot be avoided since the data is

问题 I'm attempting to insert a new row to a table in a Microsoft Access database using RODBC. Problem is the primary key column is an autonumber, and it doesn't seem to let me omit this column. I am using the sqlSave function with append = TRUE and a data frame with a single row. I have tried the following: 1: Leaving the column out of the dataframe entirely. This results in the error: Error in odbcUpdate(channel, query, mydata, coldata[m, ], test = test, : missing columns in 'data' 2: Setting
