批处理文件比较数据库备份与条件

Question

我想问一下这件事，我想每10分钟备份一次数据库表，并与现有的数据库表进行比较。这里

@echo off

set tbluser=user_tbl
set tblticket=ticket_tbl
::REM set Date 
set datetoday=%DATE:~10,4%%DATE:~4,2%%DATE:~7,2%

for /F "tokens=5-8 delims=:. " %%i in ('echo.^| time ^| find "current" ') do (
    set hh=%%i
    set mm=%%j
)
set datentime = %datetoday%%hh%%mm%
::set path
set dBackup="D:\dbBackup\dailybackup"
set wBackup="D:\dbBackup\weeklybackup"
set zip="C:\Program Files\7-Zip\7z.exe"

FC /B %wBackup%\%tblticket%.sql %dBackup%\%tblticket%_%datentime%.sql

IF %wBackup%\%tblticket%.sql EQU %dBackup%\%tblticket%_%datentime%.sql (DEL %dBackup%\%tblticket%.sql) ELSE (%zip% a -tgzip %dBackup%\%tblticket%_%datentime%.sql.gz %dBackup%\%tblticket%_%datentime%.sql
    del %dBackup%\%tblticket%_%datentime%.sql)  


@pause

Answer 1

1-我不知道如何备份你的数据库。不包含任何信息。

2-从%date%环境变量中获取当前日期。使用%time%变量对时间执行相同的操作

3-要测试两个文件的等价性，在使用FC进行比较后，检查errorlevel以了解命令是否失败

FC /b file1 file2 > nul
if errorlevel 1 (
    rem files are different
) else (
    rem files are identical
)
