Question

I have many fields in a column with a name starting with field_t and I have to change them to field_c

Examples of renaming:

field_t_detail should be field_c_detail
field_t_title should be field_c_title
field_t_id should be field_c_id
...

Here is the UPDATE statement for changing the name of one of the fields:

UPDATE my_table SET name  = field_c_meta WHERE name LIKE 'field_t_meta';

How can I change all the fields that follow this pattern instead of doing it in a one by one basis?

How about using the REPLACE function. Does it helps you?

 UPDATE my_table 
    SET `name` = REPLACE(`name`, '_t_', '_c_')
