###### T E S T . P L# -------------# A test script for exercising the Win32::ODBC extension. Install# the ODBC.PLL extension and the ODBC.PM wrapper, set up an ODBC# DSN (Data Source Name) by the ODBC administrator, then give this a try!## READ THE DOCUMENTATION -- I AM NOT RESPOSIBLE FOR ANY PROBLEMS THAT# THIS MAY CAUSE WHATSOEVER. BY USING THIS OR ANY ---# OF THE WIN32::ODBC PARTS FOUND IN THE DISTRIBUTION YOU ARE AGREEING# WITH THE TERMS OF THIS DISTRIBUTION!!!!!### You have been warned.# --- ---- ---- ------## Updated to test newest version v961007. Dave Roth <[email protected]># This version contains a small sample database (in MS Access 7.0# format) called ODBCTest.mdb. Place this database in the same# directory as this test.pl file.## --------------------------------------------------------------------## SYNTAX:# perl test.pl ["DSN Name" [Max Rows]]## DSN Name....Name of DSN that will be used. If this is# omitted then we will use the obnoxious default DSN.# Max Rows....Maximum number of rows wanted to be retrieved from# the DSN.# - If this is 0 then the request is to retrieve as# many as possible.# - If this is a value greater than that which the DSN# driver can handle the value will be the greatest# the DSN driver allows.# - If omitted then we use the default value.#####
