如何在脚本中转义 *

Question

I am trying to write a little bash script with a function doing a query:

query(){
cmd="mysql -N -B -u $user -p$password -h $host -e \"$q;\"" #2>&1";
eval $cmd
}

with

q="select * from mydatabase.mytable"

and calling query the *-character messes everything up and expands to a listing of the current directory. How can I avoid this? The function should accept any valid sql-statement. Thanks i advance for any tip. H

Disabling globbing with set -f seems to solve the problem:

query(){ set -f cmd="mysql -N -B -u $user -p$password -h $host -e "$q;"" #2>&1"; echo $cmd eval $cmd set +f }

Is this the best way?
