Need help with string variable insert in MySql

P: n/a
I have a problem with string insert that I hope someone can help me

I'm doint a one-line insert into my database from an other program and
it works perfect (thanks to Bill Karwin):

postupdate mysql -u[user] -p[password] vader -e "INSERT INTO station
(datum,tid,temp1,wspeed,wdeg,wdrpoint,wchill,press ,hum,temp2,temp3,heatindex,tdew1)
VALUES (NOW(),NOW(),$t1$,$wspkph$,$wdrdeg$,$wdrpoint$,$wc hillc$,$barmbar1$,$rh1$,$trhc1$,$tb1$,$heatindexc$ ,$dpc1$)"

My problem is that I want to add a variable that is a string (<10
char) and if I just add it it will return "No column....".

I guess that the string need to be inside ''

How can that be done in this line?

Thanks for any suggestions.

It probably depends on the shell environment you're using.
You might have to escape the single-quotes within the double-quotes:

mysql -e "INSERT ... VALUES ( ... \'$stringvalue$\' ... )"

Some shells might permit you to use literal single quotes within your
double-quoted string without escaping:

mysql -e "INSERT ... VALUES ( ... '$stringvalue$' ... )"

The best plan is to read the documentation for the shell you use, or
else do some empirical tests in your shell until you understand the
quoting rules. For example:

echo "one 'two' three"
echo "one \'two\' three"
echo 'one "two" three'
echo 'one \"two\" three'
