Preface
 
    We used to use "find" command in linux or AIX when we need to get a certain file but cannot rember the precise name.We will execute "find /pathtobegin -name xxx" in our OS prompt.Is there any tool can find a specific table of MySQL database which similarly as "find" does?
 
Introduce
 
    pt-find is a very useful tool to find out a sepcific table with a condition you've specified.It even can execute a sql operation when finding it simutaneously.
 
Procedure
 
Usage
 pt-find [OPTIONS] [DATABASES]

 --exec-plus //Specify the executing sql statement with all items at once.

 --print //Print the target database and table name.

 --printf //Print with a certain format.

 //The table has been droped directly by the last command in pt-find.
Summary
  • pt-find is rather useful when retrieving target table with flexible conditions you defined.
  • pt-find has a lot of options.We should be more careful when using ddl statement by "--exec" or "--exec-plus".
  • We can use it to collect the important information about a bunch of tables easily which can increse the working efficiency.
