数据库查询在批处理文件中不起作用

Question

@echo off

set user_name=username
set password=
set sid=sid

@echo select distinct scid, to_char(dlog_on_timestamp,'dd-Mon-YYYY hh:mi:ss') from table where dlog_on_timestamp > sysdate-7; | sqlplus -s %user_name%/%password%@%sid% >> C:\Users\test.txt

运行此批处理文件时，> symbol created file sysdate-7。但是我需要运行DB查询，结果应该存储在test.txt中

为您的shell添加引号(cmd.exe ?)在命令周围：

@echo "select distinct scid, to_char(dlog_on_timestamp,'dd-Mon-YYYY hh:mi:ss') from table where dlog_on_timestamp > sysdate-7;" | sqlplus -s %user_name%/%password%@%sid% >> C:\Users\test.txt
