# Name: nls #
# Author: Randy Johnson #
# Description: Prints contents of the props$ table. This script replaces the nlsparms script. #
# The nls_database_parameters view is defined as: #
# | select name, | #
# | substr(value$, 1, 40) | #
# | from props$ | #
# | where name like 'NLS%' | #
# #
# While I could have simply used the nls_database_parameters view, using the #
# props$ table allows me to also display the comments, (-c option). #
# #
# Usage: nls [options] #
# #
# Options: #
# -h, --help show this help message and exit #
# -c include property comments #
# -n NAME where upper(name) like upper(%currency%) ... #
# -s print SQL query. #
# -v print version info. #
# #
# History: #
# #
# Date Ver. Who Change Description #
# ---------- ---- ---------------- ------------------------------------------------------------- #
# 03/06/2015 1.00 Randy Johnson Initial write. #
# 07/17/2015 2.00 Randy Johnson Updated for Python 2.4-3.4 compatibility. #
# 07/17/2015 2.20 Randy Johnson Added prompts for username, password, tnsname. #
