mysqldump

  一、mysqldump命令

  mysql数据库导出要用到MySQL的mysqldump工具,基本用法是: 

shell> mysqldump [OPTIONS] database [tables]

  如果你不给定任何表,整个数据库将被导出。

  通过执行mysqldump --help,你能得到你mysqldump的版本支持的选项表。 

  注意,如果你运行mysqldump没有--quick或--opt选项,mysqldump将在导出结果前装载整个结果集到内存中,如果你正在导出一个大的数据库,这将可能是一个问题。 

  1.1、mysqldump支持下列选项: 

  --add-locks 

  在每个表导出之前增加LOCK TABLES并且之后UNLOCK TABLE。(为了使得更快地插入到MySQL)。 

  --add-drop-table 

  在每个create语句之前增加一个drop table。 

  --allow-keywords 

  允许创建是关键词的列名字。这由表名前缀于每个列名做到。 

  -c, --complete-insert 

  使用完整的insert语句(用列名字)。 

  -C, --compress 

  如果客户和服务器均支持压缩,压缩两者间所有的信息。 

  --delayed 

  用INSERT DELAYED命令插入行。 

  -e, --extended-insert 

  使用全新多行INSERT语法。(给出更紧缩并且更快的插入语句) 

  -#, --debug[=option_string] 

  跟踪程序的使用(为了调试)。 

  --help 

  显示一条帮助消息并且退出。 

  LOAD DATA INFILE

  --fields-terminated-by=... 

  --fields-enclosed-by=... 

  --fields-optionally-enclosed-by=...

  --fields-escaped-by=... 

  --fields-terminated-by=... 

  这些选择与-T选择一起使用,并且有相应的LOAD DATA INFILE子句相同的含义。
