I have a question about asynchronous function. Here my function
"My_function":
function My_function (my_name, callback){
stmt = db.prepare ("SELECT number_table1 from my_table1 WHERE user=?");
stmt.bind(my_name);
stmt.get(function(error,row){
if(error){
throw err;
}
else{
if(row){
callback(number_table1);
}
else{
console.log("error");
}
}
});
}
Work fine but I have 2 tables and I need do other query and I need add two
numbers so... in my function I need do too this query:
stmt = db.prepare ("SELECT number_table2 from my_table2 WHERE user=?");
and finally return back in my callback "number_table1 + number_table2".
Somebody know how to solve it? Thanks in advance.
Best regards!
