下面的代码正在返回：

案例“$type”在

                2)
                echo "Type is outbound: $type"
                        contact=$(sqlplus -s ${SQLPLUS_INFO} <<EOF
                        SELECT email FROM table WHERE email = 'x';
                        exit
                        EOF)
                        echo
                        echo $contact
                        echo
                ;;

                1)
                echo "Type is inbound: $type"
                ;;
        esac

但我只想：

电子邮件 - - - - - - - - - - - - - - - - - - - - - - - - - ------------------------------------------- email@email.com

请问有什么帮助吗？

Answer 1

The sqlplus command set pagesize 0 turns off column headers and other pagination stuff.

case "$type" in
    2)  echo "Type is outbound: $type"
        contact=$(sqlplus -s ${SQLPLUS_INFO} <<EOF
            set pagesize 0
            SELECT email FROM table WHERE email = 'x';
            exit
EOF
        )
        printf "\n%s\n\n" "$contact"
    ;;

EOF
