When I run this, it always updates the record, not matter what the value for $ethernet_address is. I have tested this by changing the line under else to echo "Update" Every time the script is run, it comes back with update.
I then we back and commented out the whole if/else statement and had only the line for RESULT=, and then did echo $RESULT. It returns nothing. Not a 0 or a 1, nothing. > From: gerald_clark <[EMAIL PROTECTED]> > Date: Mon, 09 Feb 2004 14:28:27 -0600 > To: Mike Tuller <[EMAIL PROTECTED]> > Cc: MySql List <[EMAIL PROTECTED]> > Subject: Re: There has to be a way to do this > > This is NOT a script that can run under mysql. > It is a bash script that calls mysql. > > MYSQL="/usr/local/mysql/bin/mysql --user=$username --password=$password > --host=$server cetechnology" > > RESULT=`echo "select count(*) from hardware_assets where > ethernet_address='$ethernet_address'" | $MYSQL > if [ "$RESULT" = "0" ] ; then > echo "INSERT INTO hardware_assets (ethernet_address) VALUES > ($ethernet_address);" |$MYSQL > else > echo "UPDATE hardware_assets SET operating_system='10.3.3';" | $MYSQL > fi > > > Mike Tuller wrote: > >> I changed my script to this: >> >> /usr/local/mysql/bin/mysql --user=$username --password=$password >> --host=$server >> >> RESULT=`echo "select count(*) from hardware_assets where >> ethernet_address='$ethernet_address'" | cetechnology' >> if [ "$RESULT" = "0" ] ; then >> echo "INSERT INTO hardware_assets (ethernet_address) VALUES >> ($ethernet_address);" >> else >> echo "UPDATE hardware_assets SET operating_system='10.3.3';" >> fi >> >> Where cetechnology is the database.
