Check if mysql database exists, perform action based on result

Question

Is it possible from within a bash script to check if a mysql database exists. Depending on the result then perform another action or terminate the script?

Answer 1

Use the -e option to the mysql command. It will let you execute any query (assuming the right credentials).

This may be an example:

if mysql "DATABASE_NAME" -e exit > /dev/null 2>&1; then
    echo "Exists"
else
    echo "Not exists"
