Question

Is there a mysql syntax that can preform a select values from a table, then copy those values into the same table, but update a few columns of the copy?

Table (tickets), id is primary key, auto_increment:

id | name | start_date | end_date | value | active

• Select a single row from tickets given a few values like name, start_date, end_date and value
• Copy the row that matches the statement but update the value by x
• Insert the copy with the update

Answer 1

This will insert a copy of any row(s) matching the criteria in the SELECT..WHERE statement, with the new row(s) having their prim key id autogenerated as per your spec.

INSERT INTO `tickets`(`name`, `start_date`, `end_date`, `value`, `active`)    
SELECT `name`, `start_date`, `end_date`, `value`+[value_modifier], `active`
FROM `tickets`
WHERE `name`       = '[name value]' AND
      `start_date` = [start_date]   AND  -- assuming date is timestamp otherwise wrap in '
      `end_date`   = [end_date]     AND
      `value`      = [some_value]        -- assuming value is number    

If it was a matter of just needing to update -but not copy- rows that match certain criteria then obviously you’d just use an UPDATE statement
