How can i change this Oracle SQL to MySQL -


the following oracle sql is

merge table1 rs  using table2 ch  on (rs.id = ch.id)  when matched      update set rs.column = ch.column      rs.column not null

i want change sql mysql. how can that?

that merge doing update, not insert.

so can use update statement 

update table1 rs inner join table2 ch on rs.id = ch.id set rs.column = ch.column rs.column not null

and if need upsert, mysql has insert on duplicate key update syntax
