Can we Execute SQL Queries in JQuery

can we execute mySQL queries in jQuery Calllback functions & misc. functions

like simple query

UPDATE EMPLOYEE SET PAY = PAY + 500 WHERE E_ID = '32'

Answer

The best thing you can do is to issue an AJAX request to a server and then execute this query using a server side code.

You can use jQuery.post() in this case.

Write a server side logic to execute the SQL command, in a page. Then using AJAX issue a request to that page.

Sample Code

$(function(){
    // Bind a click event to your anchor with id `updateSal`
    $("#updateSal").click(function(){
        // get your employeeID
        var empID = "32"; 
        // issue an AJAX request with HTTP post to your server side page. 
        //Here I used an aspx page in which the update login is written
        $.post("test.aspx", { EmpID: empID},
            function(data){
                // callack function gets executed
                alert("Return data" + data);
        });

        // to prevent the default action
        return false;
    });
});
