How to get data from database in javascript based on the value passed to the function

Question

In my web application, I want to retrieve data from database based on the value that is passed to the function. I wrote the query as follows.

Answer 1

The error is coming as your query is getting formed as

SELECT * FROM Employ where number = parseInt(val);

I dont know which DB you are using but no DB will understand parseInt.

What you can do is use a variable say temp and store the value of parseInt(val) in temp variable and make the query as

SELECT * FROM Employ where number = temp;
