MySQL - SHOW语句

SHOW 语句

MySQL [(none)]> HELP SHOW;

一. SHOW {BINARY | MASTER} LOGS 列出二进制列表

MySQL [(none)]> SHOW BINARY LOGS\G
*************************** 1. row ***************************
 Log_name: mysql-bin.000015
File_size: 4714627
2 rows in set (0.00 sec)

MySQL [(none)]> SHOW MASTER LOGS\G
*************************** 1. row ***************************
 Log_name: mysql-bin.000015
File_size: 4714627
2 rows in set (0.00 sec)

二. SHOW BINLOG EVENTS [IN 'log_name'] [FROM pos] [LIMIT [offset,] row_count] 列出二进制日志事件

• IN 'log_name' 指定要查询的binlog文件名(不指定就是第一个binlog文件)
• FROM pos 指定从哪个pos起始点开始查起(不指定就是从整个文件首个pos点开始算)
• LIMIT [offset,] 偏移量(不指定就是0)

• row_count 查询总条数(不指定就是所有行)

  MySQL [(none)]> SHOW BINLOG EVENTS IN 'mysql-bin.000015' LIMIT 3,2\G
  *************************** 1. row ***************************
   Log_name: mysql-bin.000015
        Pos: 219
   Event_type: Query
  Server_id: 1
  End_log_pos: 300
       Info: BEGIN
  *************************** 2. row ***************************
   Log_name: mysql-bin.000015
        Pos: 300
   Event_type: Query
  Server_id: 1
  End_log_pos: 526

• rows in set (0.01 sec)

like_or_where: {
    LIKE 'pattern'
  | WHERE expr
}

If the syntax for a given SHOW statement includes a LIKE 'pattern'
part, 'pattern' is a string that can contain the SQL % and _ wildcard
characters. The pattern is useful for restricting statement output to
matching values.

Several SHOW statements also accept a WHERE clause that provides more
flexibility in specifying which rows to display. See
