which shell script are you using,

you would need to use sqlplus for oracle and send commands and assign results,
for access to mysql you would use mysql ..
There are several references
http://www.oracle.com/technetwork/articles/linux/saternos-scripting-088882.html

For mysql

Sample script for automation:

#!/bin/ksh
echo "SELECT TNAME FROM TAB;" |\
/u01/app/oracle/product/11.2.0/dbhome_2/bin/sqlplus Username/Password@Hostname:Port/ServiceName 2>&1|\
/bin/egrep -v "^SQL|^$"
# Commented line
# Write related full path of /u01/app/oracle/product/11.2.0/dbhome_2/bin/sqlplus

Open in new window

Inside the script
You can remove required strings which is not required:

echo "SQL
test
blank

last" |\
/bin/egrep -v "^SQL|^$"

Open in new window

Removing lines beginning with SQL => ^SQL
and removing blank lines => ^$ => Begins with => ^, ends with => $
