If query has parameters, they are passed in this step. Query execution, where database actually executes a query.

#HOW TO INSTALL GFORTRAN R HOW TO#

Query preparation, where database plans how to execute a query.

In parameterized queries, query execution is splitted into three steps:

Postgresql - make sure that Use Server Side Prepare configuration option is checked (if you are unix/linux user check for UseServerSidePrepare parametr in your odbc.ini file and make sure it is equal to 1).

This is not necessary, but will speed up the query execution and lower a risk of unexpected types conversion.Д®nabling support for SQLDescribeParam() depends on the driver, e.g.: Try to enable support for SQLDescribeParam() in your ODBC drivers. R CMD INSTALL RODBCext ODBC source configuration

#HOW TO INSTALL GFORTRAN R CODE#

The following code will download the repository code to your computer, and install the package directly using R tools (Windows users may also have to add R and git to their path) Obtain recent gcc, g++, and gfortran compilers (see above instructions). Install RODBCext from the Github source code.Дevtools:: install_github( 'zozlak/RODBCext') From source via git.In R, paste the following into the console: Install the devtools package (if necessary). Windows users should include the checkbox option of installing Rtools to their path for easier command line usage. Windows users can install the Rtools suite while Mac users will have to download the necessary tools from the Xcode suite and its related command line tools (found within Xcode's Preference Pane under Downloads/Components) most Linux distributions should already have up to date compilers (or if not they can be updated easily). Obtain recent gcc, g++, and gfortran compilers.

Unfortunately due to a bug in devtools this solution doesn't work on 64-bit linux platforms. In R, paste the following into the console: install.packages( 'RODBCext') From GitHub using devtoolsДevtools package provide an easy way to install packages from the GitHub. Morover parametrized queries speed up query execution if it is repeated many times (because query planning is done only once). Parameterized queries are the kosher way of executing SQL queries when query string contain data from untrusted sources (especially user input). Extension to the RODBC R package providing support for parameterized queries.
