两个小例子：把从表中取得的数据传给Unix的shell变量

[oracle@redhat ~]$ cat sqlvalue
#!/bin/bash

VALUE=`sqlplus -s scott/tiger <set pagesize 0 feedback off verify off heading off echo off
select count(deptno) from dept;
exit;
END`
echo ""$VALUE" rows returned from database"

[oracle@redhat ~]$ cat sqlvalue2
#!/bin/bash

sqlplus -s >junk1 /nolog <connect scott/tiger
column num_rows new_value num_rows format 9999
select count(*) num_rows from dept;
exit num_rows
EOF
echo "Number of rows are: $?"
