【MySQL】經常使用拼接語句html

前言：在MySQL中 CONCAT ()函數用於將多個字符串鏈接成一個字符串，利用此函數咱們能夠將原來一步沒法獲得的sql拼接出來，在工做中也許會方便不少，下面主要介紹下幾個經常使用的場景。python

注：適用於5.7版本 低版本可能稍許不一樣。mysql

1.拼接查詢全部用戶
mysql">SELECT DISTINCT
    CONCAT(
        'User: \'',
        USER,
        '\'@\'',
        HOST,
        '\';'
    ) AS QUERY
FROM
    mysql.USER;
# 當拼接字符串中出現'時 需使用\轉義符
2.拼接DROP table
  SELECT CONCAT( 'DROP table ', TABLE_NAME, ';' ) FROM information_schema. TABLES WHERE TABLE_SCHEMA = 'test'; SELECT CONCAT( 'DROP table ', TABLE_NAME, ';' ) FROM information_schema. TABLES WHERE TABLE_SCHEMA = 'test';SELECT CONCAT( 'DROP table ', TABLE_NAME, ';' ) FROM information_schema. TABLES WHERE TABLE_SCHEMA = 'test';SELECT CONCAT( 'DROP table ', TABLE_NAME, ';' ) FROM information_schema. TABLES WHERE TABLE_SCHEMA = 'test';
3.拼接kill鏈接
  SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';  SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';  SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';  SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';  SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index'; SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index'; SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';SELECT concat('KILL ', id, ';') FROM information_schema. PROCESSLIST WHERE STATE LIKE 'Creating sort index';
4.拼接建立數據庫語句
  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );  SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' ); SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' ); SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' ); SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );SELECT CONCAT( 'create database ', '`', SCHEMA_NAME, '`', ' DEFAULT CHARACTER SET ', DEFAULT_CHARACTER_SET_NAME, ';' ) AS CreateDatabaseQuery FROM information_schema.SCHEMATA WHERE SCHEMA_NAME NOT IN ( 'information_schema', 'performance_schema', 'mysql', 'sys' );
5.拼接建立用戶的語句
  SELECT CONCAT( 'create user \'', user, '\'@\'', Host, '\'' ' IDENTIFIED BY PASSWORD \'', authentication_string, '\';' ) AS CreateUserQuery FROM mysql.`user` WHERE `User` NOT IN ( 'root', 'mysql.session', 'mysql.sys' ); #有密碼字符串哦 在其餘實例執行 可直接建立出與本實例相同密碼的用戶  SELECT CONCAT( 'create user \'', user, '\'@\'', Host, '\'' ' IDENTIFIED BY PASSWORD \'', authentication_string, '\';' ) AS CreateUserQuery FROM mysql.`user` WHERE `User` NOT IN ( 'root', 'mysql.session', 'mysql.sys' ); #有密碼字符串哦 在其餘實例執行 可直接建立出與本實例相同密碼的用戶  SELECT CONCAT( 'create user \'', user, '\'@\'', Host, '\'' ' IDENTIFIED BY PASSWORD \'', authentication_string, '\';' ) AS CreateUserQuery FROM mysql.`user` WHERE `User` NOT IN ( 'root', 'mysql.session', 'mysql.sys' );

若是增長了-t命令項，則會顯示|格式post

若是使用-vvv選項，則會回顯命令。

mysql -h 146.240.54.1 -P 60028 -u dba -p123456 -Dtestdb -N<1.sql

若是使用-N選項，則不顯示標題。

在mysql命令行下，能夠直接執行批處理文件。

mysql>. 1.sql

shell 下執行mysql 命令

 

原文連接

在shell開發中，不少時候咱們須要操做mysql數據庫（好比：查詢數據、導出數據等），可是咱們又沒法進入mysql命令行的環境，就須要在shell環境中模擬mysql的環境，使用mysql相關命令，本文總結幾種shell操做mysql的方法，供你們參考。

方案1

  1. mysql -uuser -ppasswd -e"insert LogTable values(...)"  
 
優勢：語句簡單
缺點：支持的sql相對簡單
 

方案2

準備一個sql腳本，名字爲update.sql，例如：
  1. CREATE TABLE `user` (  
  2.   `id` varchar(36) NOT NULL COMMENT '主鍵',  
  3.   `username` varchar(50) NOT NULL COMMENT '用戶名',  
  4.   `password` varchar(50) NOT NULL COMMENT '用戶密碼',  
  5.   `createdate` date NOT NULL COMMENT '建立時間',  
  6.   `age` int(11) NOT NULL COMMENT '年齡',  
  7.   PRIMARY KEY  (`id`)  
  8. ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='用戶信息表';  
  9. DROP TABLE IF EXISTS `visit_log`;  
  10. CREATE TABLE `visit_log` (  
  11.   `id` varchar(36) character set utf8 NOT NULL,  
  12.   `type` int(11) NOT NULL,  
  13.   `content` text character set utf8 NOT NULL,  
  14.   `createdate` date NOT NULL,  
  15.   PRIMARY KEY  (`id`)  
  16. ) ENGINE=MyISAM DEFAULT CHARSET=latin1 COMMENT='訪問日誌';  
 
 新建一個update_mysql.sh，內容以下：
[python]  view plain copy
 
  1. use chbdb;  
  2. source update.sql  
 
 
而後執行以下命令：
[python]  view plain copy
 
  1. cat update_mysql.sh | mysql --user=root -ppassword  
 
優勢：支持複雜的sql腳本
缺點：
1> 須要兩個文件：update.sql和update_mysql.sh
2> 一旦中間出錯，以後腳本就不會執行，例如：
若是第一張表已經存在，則會報出以下異常：
ERROR 1050 (42S01) at line 1 in file: 'update.sql': Table 'user' already exists
而後腳本退出，第二張表也就沒法建立。

方案3

    新建一個shell腳本，格式以下：
 
  1. #!/bin/bash  
  2. mysql -u* -h* -p* <<EOF  
  3.     Your SQL script.  
  4. EOF  
 
例如：
 
  1. #!/bin/bash  
  2. mysql -uroot  -ppassword <<EOF  
  3.    use chbdb;  
  4.     CREATE TABLE user (  
  5.   id varchar(36) NOT NULL COMMENT '主鍵',  
  6.   username varchar(50) NOT NULL COMMENT '用戶名',  
  7.   password varchar(50) NOT NULL COMMENT '用戶密碼',  
  8.   createdate date NOT NULL COMMENT '建立時間',  
  9.   age int(11) NOT NULL COMMENT '年齡',  
  10.   PRIMARY KEY  (`id`)  
  11. ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='用戶信息表';  
 
優勢：
1>支持複雜的sql腳本
2>無需其它額外文件
缺點：
1> 表名、字段不能使用單引號，須要修改原有sql語句
2> 一旦中間出錯，以後腳本就不會執行，例如：
若是第一張表已經存在，則會報出以下異常：
ERROR 1050 (42S01) at line 1 in file: 'update.sql': Table 'user' already exists
而後腳本退出，第二張表也就沒法建立。

方案4

準備一個sql腳本，如update.sql，而後執行以下命令：
[python]  view plain copy
 
  1. mysql -uroot -ppassword < update.sql  
 
優勢：支持複雜的sql腳本
缺點：
1> 一旦中間出錯，以後腳本就不會執行，例如：
若是第一張表已經存在，則會報出以下異常：
ERROR 1050 (42S01) at line 1 in file: 'update.sql': Table 'user' already exists
而後腳本退出，第二張表也就沒法建立。
 
 
    你們知道在mysql命令行中使用source命令，即便中間出錯，後續腳本也會繼續執行，可是如上幾種方式，均沒法解決該問題，若是你們有好的建議，請回復，謝謝。
