MySQL 连接本地数据库、远程数据库命令

一、MySQL 连接本地数据库，用户名为“root”，密码“123”（注意：“-p”和“123” 之间不能有空格）

C:/>mysql -h localhost -u root -p123

二、MySQL 连接远程数据库（192.168.0.201），端口“3306”，用户名为“root”，密码“123”  (注意:端口"_P"是大写)

C:/>mysql -h 192.168.0.201 -P 3306 -u root -p123

三、MySQL 连接本地数据库，用户名为“root”，隐藏密码

C:/>mysql -h localhost -u root -pEnter password:

四、MySQL 连接本地数据库，用户名为“root”，指定所连接的数据库为“test”

C:/>mysql -h localhost -u root -p123 -D testmysql>select database();+------------+| database() |+------------+| test       |+------------+

This is free software,and you are welcome to modify and redistribute it under the GPL licenseUsage: mysql [OPTIONS] [database]  -?, --help          Display this help and exit.  -I, --help          Synonym for -?  --auto-rehash       Enable automatic rehashing. One doesn't need to use                      'rehash' to get table and field completion, but startup                      and reconnecting may take a longer time. Disable with                      --disable-auto-rehash.  -A, --no-auto-rehash                       No automatic rehashing. One has to use 'rehash' to get                      table and field completion. This gives a quicker start of                      mysql and disables rehashing on reconnect. WARNING:                      options deprecated; use --disable-auto-rehash instead.  -B, --batch         Don't use history file. Disable interactive behavior.                      (Enables --silent)  --character-sets-dir=name                       Directory where character sets are.  --default-character-set=name                       Set the default character set.  -C, --compress      Use compression in server/client protocol.  -#, --debug[=#]     This is a non-debug version.

(Disables --force and history                      file)  -E, --vertical      Print the output of a query (rows) vertically.  -f, --force         Continue even if we get an sql error.  -G, --named-commands                       Enable named commands. Named commands mean this program's                      internal commands; see mysql> help . When enabled, the                      named commands can be used from any line of the query,                      otherwise only from the first line, before an enter.                      Disable with --disable-named-commands. This option is                      disabled by default.  -g, --no-named-commands                       Named commands are disabled. Use /* form only, or use                      named commands only in the beginning of a line ending                      with a semicolon (;) Since version 10.9 the client now                      starts with this option ENABLED by default! Disable with                      '-G'. Long format commands still work from the first                      line.

This is useful for                      skipping updates to other database in the update log.  -p, --password[=name]                       Password to use when connecting to server. If password is                      not given it's asked from the tty.  -W, --pipe          Use named pipes to connect to server.  -P, --port=#        Port number to use for connection.  --prompt=name       Set the mysql prompt to this value.  --protocol=name     The protocol of connection (tcp,socket,pipe,memory).  -q, --quick         Don't cache result, print it row by row.
