如何遍历目录中的文件(它们都是CSV文件),然后使用mysql -u root
登录mysql(为简单起见,没有密码)并将它们全部添加到mysql表中?这是将文件快速加载到mysql中的查询:
LOAD DATA LOCAL INFILE "C:/prog/mydb_load_Cards_chunks.dump" INTO TABLE vcc2.tmp_cards CHARACTER SET latin1
FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 LINES;
如何在登录mysql时对目录中的每个文件执行此操作?

尝试:
档案:load_csv.sh (-r-x------ user user load_csv.sh*)
#!/bin/bash
for current_csv in *.csv
do
mysql --login-path=myconnection -e "USE test" -e "
LOAD DATA LOCAL INFILE '$current_csv'
INTO TABLE temp_table
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '\"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(DATE, TIME);"
done

Query OK, 0 rows affected (0.00 sec)
mysql> \! bash
$ ./load_csv.sh
$ exit
exit
mysql> SELECT `id`, `DATE`, `TIME`
