问题 We use MySQL tables to which we add new fields from time to time as our product evolves. I'm looking for a way to export the structure of the table from one copy of the db, to another, without erasing the contents of the table I'm importing to.

I tried to use mysqldump, but it seems I can only copy the

问题 if I started mysqldump on a database, and then created a new table with new data, will this table be dumped? what's the concurrency behavior here? 回答1: Well, that is not sure, from Mysql Manual: --single-transaction This option sends a START TRANSACTION SQL statement to the server before dumping data. It is useful only with transactional tables such as InnoDB and BDB, because then it dumps the consistent state of the database at the time when BEGIN was issued without blocking any applications

Is there a good way to perform SQL dump of MySQL database in DataGrip?

问题 I'm trying to use JetBrains DataGrip as my primary DB tool. However, I still find myself using SequelPro for SQL Dump. Here is why: On a database level, I couldn't find any SQL dump functionality. The only options seems to be "copy DDL", which copies the schema, but not the content. On a table level, sure, I can export data as SQL Inserts. But then it seems the only way to do so is to export it from each table separately, which is unacceptable. Another downside is, when exporting data as

1、系统管理 1.1 连接MySQL   格式 : mysql -h主机地址 -u用户名 -p用户密码   举例 :   例1 :连接到本机上的MySQL。   首先在打开DOS窗口,然后进入目录 mysqlbin,再键入命令"mysql –u root –p",回车后提示你输密码,如果刚安装好MySQL,超级用户"root"是没有密码的,故直接回车即可进入到MySQL中了,MySQL的提示符是: mysql>。   例2 :连接到远程主机上的MYSQL。假设远程主机的IP为:110.110.110.110,用户名为root,密码为abcd123。则键入以下命令: mysql -h 110.110.110.110 -u root –p abcd123   备注 :u与root可以不用加空格,其它也一样。   退出MySQL命令: exit (回车)。 1.2 修改新密码   格式 :mysqladmin -u用户名 -p旧密码 password 新密码   举例 :   例1 :给root加个密码ab12。首先在DOS下进入目录mysqlbin,然后键入以下命令: mysqladmin -u root -password ab12   备注 :因为开始时root没有密码,所以-p旧密码一项就可以省略了。   例2 :再将root的密码改为djg345。 mysqladmin -u
