Domanda

I have below queries regarding MySQL replication.

1) Suppose i want to do master-slave replication with different table name then is it possible ?

Ex. Master >> Db1.student i want to replicate with Slave >> Db2.employee table.

2) If i want to replicate only specific columns in same table then is it possible ?

Master >> Db1.student

  • id
  • firstname
  • lastname
  • parentname
  • status

Slave >> Db2.student

  • id
  • firstname
  • lastname

Apart from that is there any other way to achieve/solution above query (i.e MySQL Views) or any other alternate way ?

Thanks in advance.

Soluzione

The eassiest way is to use a View like this:

CREATE VIEW Db2.student AS 
     SELECT id, firstname, lastname 
       FROM Db1.student;

If you want to filter some content in the Db2 view you could add some filters to the view creation. For example:

CREATE VIEW Db2.student AS 
     SELECT id, firstname, lastname 
       FROM Db1.student
      WHERE Db1.student.status = 1; 

I hope it works for you.
