Body
First of all thanks to Mark for 'argparse' code. I have figured out the way to take arguments from command line specified by flags. I am pasting the code below which uses a modified 'Mark' code and a small module which shows how to use the arguments collected via commandline: <pre><code>import argparse parser = argparse.ArgumentParser() #-db DATABASE -u USERNAME -p PASSWORD -size 20000 parser.add_argument("-host", "--hostname", dest = "hostname", default = "xyz.edu", help="Server name") parser.add_argument("-db", "--database", dest = "db", default = "ding_dong", help="Database name") parser.add_argument("-u", "--username",dest ="username", help="User name") parser.add_argument("-p", "--password",dest = "password", help="Password") parser.add_argument("-size", "--binsize",dest = "binsize", help="Size", type=int) args = parser.parse_args() print( "Hostname {} db {} User {} Password {} size {} ".format( args.hostname, args.db, args.username, args.password, args.binsize )) def ConnectToDB(): print ('Trying to connect to mySQL server') # Try to connect to the database try: con=sql.connect(host=args.hostname, user= args.username, passwd= args.password) print ('\nConnected to Database\n') # If we cannot connect to the database, send an error to the user and exit the program. except sql.Error: print ("Error %d: %s" % (sql.Error.args[0],sql.Error.args[1])) sys.exit(1) return con </code></pre> One of my concern was how to use variables from arguments to the code. For that two things need to be done <ol> <li>Add 'dest' to the add_argument line e.x. dest ="username" which means the value collected from comamnd line will be assigned to variable 'username'</li> <li>Whenever an you use such command line assigned variables from 'dest' just add 'args' before variable e.x con=sql.connect(host=args.hostname, user= args.username, passwd= args.password)</li> </ol> Done Thanks AK

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
