SQL结果在Batch FIle中

Question

爵士。这是我的代码

@echo off 
SET path=C:\Users\neca\Desktop cd C:\wamp\bin\mysql\mysql5.5.24\bin 

FOR /F "tokens=*" %%D IN ('mysql -uroot -e "SHOW TABLES from sample"') do echo %%D

pause

但是在我的数据库中我只有2个表（样本和测试）。为什么这样呢？ 此代码的输出是

Tables_in_sample 
sample 
test

其中Tables_in_sample是我没有制作的表。

Answer 1

Tables_in_sample只是mysql客户端的标题

实施例

mysql> show tables from mysql;

28 rows in set (0.00 sec)

mysql>

请参阅输出标题为Tables_in_mysql

SUGGESTION

只需使用-ANe而非-e

停用标头

@echo off 
SET path=C:\Users\neca\Desktop cd C:\wamp\bin\mysql\mysql5.5.24\bin 

FOR /F "tokens=*" %%D IN ('mysql -uroot -ANe "SHOW TABLES from sample"') do echo %%D

pause

试一试!!!

Answer 2

@echo off SET path = C：\ Users \ neca \ Desktop cd C：\ wamp \ bin \ mysql \ mysql5.5.24 \ bin

FOR / F＆＃34;令牌= *＆＃34; %% D IN（＆＃39; mysql -uroot -N -B -e＆＃34;示例＆＃34;＆＃39;中的SHOW TABLES）回显%% D
