Linux – Store a sql select value in a variable bash

Question

I want to store the value of the sqlite statement in a variable

backup=$(sqlite3 "/home/miguel/Desktop/SO/ProjetoFinal/Backup_Principal.db" "SELECT periocidade_backup FROM STORAGE WHERE path'$path';")

But when i echo $backup it returns the following:

sqlite3 “/home/miguel/Desktop/SO/ProjetoFinal/Backup_Principal.db” “SELECT periocidade_backup FROM STORAGE WHERE path=’$path’;”

What am I doing wrong?

Answer

the part of your code '$path' is using a single quote which is literal and show exactly as what is in the quotes, which would not use the variable’s value. using speech marks like the following should work, "'$path'"
