DireXions – Connectivity Inside & Out File I/O Updates, ODBC 64-bit, & SQL Command Utility Presenter: Devon Austen

DireXions – Connectivity Inside & Out Outline Overview How we made file I/O easier How we made file I/O more useful We live in a 64-bit world The command line is King

DireXions – Connectivity Inside & Out Overview What’s new in the file I/O products But first a quick discussion about key topics What is ODBC? – Open DataBase Connectivity – Common interface standard – Uses Structured Query Language (SQL)

DireXions – Connectivity Inside & Out Overview PxPlus ODBC Driver – PxPlus implementation of ODBC API – Allows programs that use ODBC interface to connect to PxPlus data – Local or remote using file server PxPlus File Server – Access PxPlus data on remote systems PVKIO library – PxPlus file I/O library for accessing PxPlus data – Local or remote using file server

DireXions – Connectivity Inside & Out How We Made File I/O Easier

DireXions – Connectivity Inside & Out New Installers ODBC Drivers and File Server – New and improved installers – Faster and light weight – Default install location of file I/O products now C:\PVX Plus Technologies\xxx Installers are NOT MSI

DireXions – Connectivity Inside & Out New Installers New PxPlus ODBC driver installer

DireXions – Connectivity Inside & Out New Installers New File Server installer

DireXions – Connectivity Inside & Out Case Insensitive Table Names The ODBC driver now ignores case when processing table names in SQL commands Reduces the number of errors ODBC driver no longer supports table names that only differ in case

DireXions – Connectivity Inside & Out TIMESTAMPADD Improvements Scalar function TIMESTAMPADD has been enhanced – TIMESTAMPADD function adds an interval to a timestamp – Used to be limit on size of interval – Now standard integers usable for intervals

DireXions – Connectivity Inside & Out Miscellaneous Improvements File DSNs Windows file server startup Large tables using bookmarks PVKIO library function Pvk_RestrictedRead ODBC views

DireXions – Connectivity Inside & Out How We Made File I/O More Useful

DireXions – Connectivity Inside & Out Enhanced VLR File Support File I/O products now support PxPlus enhanced VLR format files – Allow more than 255 key entries per key block

DireXions – Connectivity Inside & Out EFF File Support Added support for EFF files in the PVKIO library

DireXions – Connectivity Inside & Out Per Connection Read Only Flag New ODBC connection string parameter ReadOnly=[0|1] Can be set using ODBC Administrator configuration page Can be set manually

DireXions – Connectivity Inside & Out We Live In a 64-bit World Whether we like it or not

DireXions – Connectivity Inside & Out Running 32-bit File I/O Applications on a 64-bit OS 32-bit ODBC drivers can run on 64-bit OS’s – Limited to 32-bit applications 32-bit File Servers can run on 64-bit OS’s

DireXions – Connectivity Inside & Out Confusion Caused by 32-bit ODBC Driver on 64-bit Windows On 64-bit OS’s there are two ODBC Administrators a 32-bit and a 64-bit version – 64-bit ODBC Administrator is located in: Control Panel -> Administrative Tools – 32-bit ODBC Administrator is located in: C:\Windows\SysWOW64 64-bit applications cannot use the 32-bit ODBC driver

DireXions – Connectivity Inside & Out PxPlus 64-bit ODBC Driver Increasing number of 64-bit platforms and applications Current ODBC driver will not work So we developed a 64-bit ODBC driver Can be installed alongside the 32-bit ODBC driver Must re-enter activation information Use the ODBC Administrator in the control panel

DireXions – Connectivity Inside & Out The Command Line is King

DireXions – Connectivity Inside & Out PxPlus SQL Command Line Client Windows & Linux versions Windows PxPlus SQL Command Line Client installed with version 10 ODBC driver Linux PxPlus SQL Command Line Client has separate instraller Connects to local or remote PxPlus data and executes SQL commands

DireXions – Connectivity Inside & Out When and Why to Use It Quick and direct access to PxPlus data Testing ODBC driver and data sources Can be executed from web pages, scripts, and applications

DireXions – Connectivity Inside & Out How to Use It From the command line pxpsql [connection info] [options] SQL command Example: Get all data from a local table named “products” pxpsql -d C:\pxp_data SELECT * FROM \”Sales Rep\”

DireXions – Connectivity Inside & Out How to Use It pxpsql has –h or --help parameters Windows/Unix command line considerations – Quotes (‘/”) – Parenthesis () – Asterisks (*) SQL syntax for table names with spaces requires quotes (“) Escape character is (\) for Windows and Linux

DireXions – Connectivity Inside & Out How to Use It pxpsql has -c or --connection-string parameters which accept a connection string in the following format “param1=val1; param2=val2; …” Example: “Directory=/home/devon/pxp_data; RemotePVKIOHost= ; RemotePVKIOPort=20222;”

DireXions – Connectivity Inside & Out How to Use It pxpsql has -f or –config-file parameters – INI style file – Long style parameters – Overridden by command line parameters

DireXions – Connectivity Inside & Out Demonstration Example using pxpsql
