Question

Where I have more than one table in my database for use with (similar, but) different products.

Is it possible to select a table to work with based on a parameter (example below)?
(This would save me having multiple similar copies of the same procedure).

DROP PROCEDURE IF EXISTS `dostuff` $$
CREATE PROCEDURE `dostuff`(IN prod_code VARCHAR(10))
BEGIN

IF INSTR(prod_code, 'product_a') THEN
    myTable = product_a_table
ELSE IF INSTR(prod_code, 'product_b') THEN
    myTable = product_b_table
END IF

-- do stuff on myTable such as SELECT and UPDATE

END $$

DELIMITER ;

It is possible to create a command like this:

SET @query := CONCAT("REPAIR TABLE ", @tableName);             
PREPARE stmt FROM @query;             
EXECUTE stmt;             
DEALLOCATE PREPARE stmt;   

As you can see, you can push any string/variable you want into that command (using variables wherever you’d like.
