What I need help with is that I need to separate this one row of products into n different rows, with n being the value stored in Qtd. Example: Original: row product_code Qtd 1 111 15 row product_code Qtd 1 111 15 row product_code Qtd row product_code Qtd row product_code Qtd 1 111 15 1 111 15 1 111 15 New: row product_code Qtd 1 111 1 2 111 1 3 111 1 ... ... ... 14 111 1 15 111 1 row product_code Qtd 1 111 1 2 111 1 3 111 1 ... ... ... 14 111 1 15 111 1 row product_code Qtd row product_code Qtd row product_code Qtd 1 111 1 2 111 1 3 111 1 ... ... ... 14 111 1 15 111 1 1 111 1 1 111 1 2 111 1 2 111 1 3 111 1 3 111 1 ... ... ... ... ... ... 14 111 1 14 111 1 15 111 1 15 111 1 I need to create this new rows because they're trying to introduce a new column that represents the serial number of the products, that is unique and I'm unable to use joins because this serial number is stored in a different database. We have a way to assign a serial number to a product based on its product code, but only the first serial number is being paired correctly, and separating this single row into different rows would solve this particular problem in an practical way, if it's possible of course. We've tried doing this using our software, but it ended with only the first serial number being assigned to a row and all the others being left unused. We're hoping that this try would separate the data into different rows. Tags: sql,mysql,data-manipulationSource of the question: https://stackoverflow.com/questions/7...
