Question

我可以通过执行以下命令来通过命令行备份mysql数据库：

C：\ MySQL \ MySQL Server 5.0 \ bin \ mysqldump \“-uroot -ppassword sample＆gt; \”D：/admindb/AAR12.sql \“

但我的.mysql文件中没有DROP和CREATE数据库查询

我应该在语法中添加什么来获取创建信息到我生成的.sql文件？

    -- MySQL dump 10.11
--
-- Host: localhost    Database: sample

Answer 1

您可以使用--add-drop-table和--create-options选项。

- 加 - 降式表

在每个之前添加DROP TABLE语句   CREATE TABLE语句。

mysqldump

实际上即使没有任何其他密钥，也应添加CREATE TABLE。

更新：

backup.bat

的内容

C:\MySQL\MySQL Server 5.0\bin\mysqldump -uroot -ppassword sample >
                                                     D:/admindb/AAR12.sql
copy db_restore.sql+AAR12.sql restore.sql

假设您手动创建db_restore.sql并放置所有数据库范围的创建/删除操作。 backup.bat应该生成带有数据库drop / create和表数据的restore.sql。

Answer 2

- 加 - 降式表

- 创建选项

private void TakeDBBackup() 
{ 
string tables = ""; 

// Displaying tables from apman database 
var cmd = 
new MySqlCommand( 
"select table_name from information_schema.tables where table_schema='apman' and table_type like '%TABLE'", 
ClientConnection); 
MySqlDataReader read2 = cmd.ExecuteReader(); 
while (read2.Read()) 

// Initializing tables into a varible string. 
tables += read2["table_name"] + " "; 
read2.Close(); 

// Displays current date and time name as folder name. 
DateTime backupTime = DateTime.Now; 
int year = backupTime.Year; 
int month = backupTime.Month; 
int day = backupTime.Day; 
int hour = backupTime.Hour; 
int minute = backupTime.Minute; 
int second = backupTime.Second; 

// Creating Dumpdata directory 
string dest = Directory.GetCurrentDirectory() + "\\Dumpdata\\"; 
Directory.CreateDirectory(dest); 
string src = dest + year + "-" + month + "-" + day + "-" + hour + "-" + minute + "-" + second + ".sql"; 
var file = new StreamWriter(src); 
string cmd1 = string.Format("--force --user=root --password=passd apman > {0} {1}", src, tables); 
var proc = new ProcessStartInfo();
