I am trying to retrieve email address from MySQL database.

#!/bin/bash
MYSQLHOST="192.168.1.1"                                               
MYSQLDB="nuni"
MYSQLUSER="root"
MYSQLPASS="rootpass"
MYSQLOPTS="--user=${MYSQLUSER} --password=${MYSQLPASS} --host=${MYSQLHOST} ${MYSQLDB}"
EMAIL=echo "SELECT email FROM Edsrn WHERE userid = 1235" | mysql ${MYSQLOPTS}
echo "E-mail: $EMAIL"

What is wrong with it? I says “command not found”. Please help!

    I recommend using the -e parameter to evaluate SQL statements instead. This should be what you’re looking for:

    #!/bin/bash
MYSQLHOST="192.168.1.1"                                               
MYSQLDB="nuni"
MYSQLUSER="root"
MYSQLPASS="rootpass"
MYSQLOPTS="-s --user=${MYSQLUSER} --password=${MYSQLPASS} --host=${MYSQLHOST} ${MYSQLDB}  -e "
EMAIL=$(mysql ${MYSQLOPTS} "SELECT email FROM Edsrn WHERE userid = 1235" | tail -n 1)
echo "E-mail: $EMAIL"

    Note the tail is needed since the output from mysql looks like this:

    column
value
