I would put all my code for the prompting after the console outputting in selectAllProducts I don;t know what it is you are trying to do. How do we do all this? If you want to run code after the query completes it must go in the completion callback - anything you put after the selectAllProducts call will execute before the query completes. It must be because there is some results you want to happen before moving on. Nic writes about his development experiences related to making web and mobile development easier to understand.

This is true, and thanks again for your responses. How can I get the mySql data to print to the console first and when done prompt the User for input? Thank you for the help. Before I go forward, I must say this may not be the best solution, but it is most certainly a solution. So if I do it your way I would have to make a new function for each call that does what I would like afterward, this would then remove any reason of having a function at all. So I need to make sure it finishes first. Thanks, jimbo99999 I wear a lot of hats. Edge Out The Competition for your dream job with proven skills and certifications.

Before returning data to the client user , manipulations must be done on the external service data requested. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform.

By quit, I mean return the transformed array back to the user. . I will do a screen print of the output. If GoDoSomeStuff contains async calls then you would need to put your console.

Conclusion Maybe not the best way to do things, but keeping a counter on a per asynchronous function basis allows us to loop through a bunch of async functions and return only when everything is complete. The data is in mysql. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc. I am calling a function to get data from a mySql database and then formatting for display in the console.
