Store mysql query output into a shell variable

Question

I need a variable to hold results retrieved from the database. So far this is basically what I\'m trying with no success.

myvariable=$(mysql database -u $use         


        

Answer 1

Another example when the table name or database contains unsupported characters such as a space, or '-'

db='data-base'

db_d=''
db_d+='`'
db_d+=$db
db_d+='`'

myvariable=`mysql --user=$user --password=$password -e "SELECT A, B, C FROM $db_d.table_a;"`
