I need to export a database from a site (site 1) and import it to another database (site 2) with a different structure.
So what i am asking is this:
In the database of site 1 we are having a table called "products" and then we have a child table products_descriptions (which is connected with a foreign key with products). So in the child table we have different columns like staff, dosage, indications and so on. 
Then we have site 2's database. We got a table called products. And in that table we have a column called productDescription.
So what i need to do is to export the products_descriptions table from site 1 and import it to the productDescription column in the products table from site 2.
This question is related with the question i asked yesterday. Here is a link: MySql - Concatenate/merge multiple columns into one column with hard codded titles
But i don't think that's the right way of thinking.
So can anyone give any tip about the right approach in this situation?
