我想从命令行导出和导入MySQL数据库的.sql文件。
是否有任何命令可以在MySQL中导出.sql文件?那我该如何导入呢?
执行导入时,可能存在启用/禁用外键检查或仅导出表格结构等限制。
我们可以将这些选项设置为mysqldump
吗?
答案 0 :(得分:68)
键入以下命令以导入sql数据文件:
$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
在此示例中,使用vivek将'data.sql'文件导入'blog'数据库作为用户名:
$ mysql -u vivek -p -h localhost blog < data.sql
如果您有专用数据库服务器,请将localhost主机名替换为实际服务器名称或IP地址,如下所示:
$ mysql -u username -p -h 202.54.1.10 databasename < data.sql
要导出数据库,请使用以下命令:
mysqldump -u username -p databasename > filename.sql
请注意每种情况下的<
和>
符号。

如果您已经在运行SQL shell,则可以使用source
命令导入数据:
use databasename;
source data.sql;
答案 2 :(得分:17)
mysqldump -uuser -p db_name --events --triggers --routines > db_name.sql
答案 3 :(得分:14)
尝试
mysqldump databaseExample > file.sql
答案 4 :(得分:13)
您可以使用以下命令导出
mysqldump --database --user = root --password your_db_name&gt; export_into_db.sql
,生成的文件将在您运行此命令的同一目录中可用。
现在使用命令
登录mysqlmysql -u [用户名] -p
然后使用“source”命令和文件路径。

将整个数据库转储到文件中:
mysqldump -u USERNAME -p password DATABASENAME > FILENAME.sql

因为在最高职位之后我没有足够的声誉来评论,所以我在这里添加。
使用&#39; |&#39;在linux平台上节省磁盘空间。
thx @Hariboo,添加事件/触发器/路径参数
mysqldump -x -u [uname] -p[pass] -C --databases db_name --events --triggers --routines | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/ ' | awk '{ if (index($0,"GTID_PURGED")) { getline; while (length($0) > 0) { getline; } } else { print $0 } }' | grep -iv 'set @@' | trickle -u 10240 mysql -u username -p -h localhost DATA-BASE-NAME
一些问题/提示:
错误:......使用LOCK TABLES时不存在
# --lock-all-tables,-x , this parameter is to keep data consistency because some transaction may still be working like schedule.
# also you need check and confirm: grant all privileges on *.* to root@"%" identified by "Passwd";
ERROR 2006(HY000)第866行:MySQL服务器已经消失 mysqldump:写错了32#
# set this values big enough on destination mysql server, like: max_allowed_packet=1024*1024*20
# use compress parameter '-C'
# use trickle to limit network bandwidth while write data to destination server
ERROR 1419(HY000)第32730行:您没有SUPER权限并启用了二进制日志记录(可能想要使用安全性较低的log_bin_trust_function_creators变量)
# set SET GLOBAL log_bin_trust_function_creators = 1;
# or use super user import data
第138行的错误1227(42000):拒绝访问;您需要(至少一个)此操作的SUPER权限 mysqldump:写错了32#
# add sed/awk to avoid some privilege issues
希望这有帮助!

您可以使用此脚本从此链接提供的终端导出或导入任何数据库:https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh
echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo
mysqldump_location=/opt/lampp/bin/mysqldump
mysql_location=/opt/lampp/bin/mysql
if [ "$action" == "export" ]; then
if [ "$location_change" == "y" ]; then
read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
echo
else
echo -e "Using default location of mysqldump\n"
fi
read -p 'Give the name of database in which you would like to export: ' db_name
read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
$mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
if [ "$location_change" == "y" ]; then
read -p 'Give the location of mysql that you want to use: ' mysql_location
echo
else
echo -e "Using default location of mysql\n"
fi
read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
read -p 'Give the name of database in which to import this file: ' db_name
$mysql_location -u $u_name -p $db_name < $sql_file
else
echo "please select a valid command"
fi
