Quick check if a mysql database exists

Here is my bash code that checks if a db exists before I try to create one in a script:

DBEXISTS=$(mysql --batch --skip-column-names -e "SHOW DATABASES LIKE '"$DBNAME"';" | grep "$DBNAME" > /dev/null; echo "$?")
if [ $DBEXISTS -eq 0 ];then
	echo "A database with the name $DBNAME already exists. exiting"

This will exit out if there is a database with the name you are searching for. The tricky part for me (and always is) was this double quotes inside the single quotes in the LIKE statement.
