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

Other way:

Your Script:

#!/bin/sh

# Set these variables
MyUSER="root"   # DB_USERNAME
MyPASS="yourPass"   # DB_PASSWORD
MyHOST="yourHost"    # DB_HOSTNAME
DB_NAME="dbName"
CONTAINER="containerName" #if use docker

# Get data
data=$($MyHOST -u $MyUSER -p$MyPASS $DB_NAME -h $CONTAINER -e "SELECT data1,data2 from table_name LIMIT 1;"  -B --skip-column-names)

# Set data
data1=$(echo $data | awk '{print $1}')
data2=$(echo $data | awk '{print $2}')

# Print data
echo $data1 $data2
