IF works on the selections not on the query.
Select IF(lastname='clark','Correct',''Incorrect'), firstname from namefile;


You need to do the checking in your script.
For example in bash:
RESULT=`echo "select count(*) from manefile where lastname='clark'" | mysql database`
if [ "$RESULT" = "0" ] ; then
echo "insert into namefile .......
else
echo "update namefile ......
fi

I have posted this question a few times, and have not seen the answer that I
need.

I have a shell script, that gathers information from systems, and I want
that info to be entered into a database. I want it to check first to see if
the data is already entered, and if not, add it. If it has already been
entered, then update the record.

I would think that some type of if/else statement would work, but I can't
get the IF statement http://www.mysql.com/doc/en/IF_Statement.html to work
correctly in MySql.

Here is what I have:

"IF SELECT * FROM hardware_assets WHERE ethernet_address='$ethernet_address'
IS NULL\
   THEN INSERT into hardware_assets (ethernet_address) VALUES
($ethernet_address)\
ELSE\
   UPDATE hardware_assets SET operating_system='10.3.3'\
END IF;"

I get back that I have an error in my SQL syntax. $ethernet_address is set,
so that is not my problem.

Does anyone know a way to go about this in SQL, or in a shell script? I
don't want to do it in Perl or PHP.


Thanks, Mike
