No, we can't really help you on this because

JavaScript

INSERT INTO table1 (col1, col2, col3) values ('" + req.body.aa + "', '" + req.body.bb + "', '" + req.body.cc + "')";

is creating

JavaScript

INSERT INTO table1 (col1, col2, col3) values ('2','aa','bb')

If you don't, something else happen in your code, but we can't guess.

Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.
