嘗試從Shell腳本連接到Oracle數據庫

Question

我正在嘗試從Shell腳本連接到oracle數據庫（我是新用戶）。 然后，腳本將傳遞查詢並將結果傳輸到名為canadacount的變量。 我已經編寫了代碼，但是沒有用

#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 ：

我將連接線更改為以下內容：

connect userid/passsword@CFQ143
