尝试从 shell 脚本连接到 oracle 数据库

Question

我正在尝试从 shell 脚本连接到 oracle 数据库（我是新用户）。然后该脚本将传递一个查询并将结果传输到一个名为 canadacount 的变量。我已经写了代码，但它不起作用

#this script will attempt to connect to a remote database CFQ143 with user ID 'userid' and password 'password'.
#After loggin in it will read data from the PLATFORMSPECIFIC table.
#We can pass a query 'select count (platform) from platformspecific where platform='CANADA';
#The result from this query will be passed to a variable called canadacount which we can then echo back to the user.

canadacount='$ORACLE_HOME/bin/sqlplus -s /nolog<<EOF
connect userid/passsword@CFQ143:1521:CFQ143
set pages 0 feed off
select count (platform) from platformspecific where platform='CANADA';
exit
EOF'
echo $canadacount

Answer 1

答案是：

我把连接线改成如下：

connect userid/passsword@CFQ143
