Mysql Rename Multiple tables with a pattern

Question

I know how to run

RENAME TABLE onetable_test TO onetable;

But is there a method to rename many tables with a pattern and don\'t write a lot of

Answer 1

For example:

select group_concat(v.name SEPARATOR ' ') 
from (
      select concat('rename table ', t.table_name, ' to ', substring(reverse(v.name), instr(reverse(v.name), '_') + 1, length(v.name)) name 
      from information_schema.tables t
      where 
          table_schema = 'put_your_table_schema'
          and table_name like '%_test'
     ) v;

1. Running this query will return script that should be executed to rename tables.
2. substring(reverse.....) rather than simple replace(v.name, '_test', '') used because we need to be sure that we will replace only _test occurrences only at the end of the string.

Hope it helps
