Updating a sql database using php

Question

What I am trying to do is updating multiple rows of mysql table having same id. I searched for many solutions but couldn't find appropriate one. I have a table that look likes below:

+----+--------+--------+--------------+----------+
| id | emp_id | job_id | basic_salary |   stat   |
+----+--------+--------+--------------+----------+
| 62 |    186 |     30 |         8400 | Active   |
| 64 |    110 |      8 |        12542 | Inactive |
| 65 |    110 |      5 |        12542 | Active   |
+----+--------+--------+--------------+----------+

So I want to update this table having id = 64 and emp_id = 110 as Active which should also update other rows with emp_id 110 as Inactive if they are Active so that only one record with emp id 110 remains active and rest inactive .

Will kindly appreciate the help.

Answer 1

Can try with these simple queries :-

UPDATE <table_name> SET `stat` = "Active" WHERE id = 64 AND emp_id = 110

and then :

UPDATE <table_name> SET `stat` = "Inactive" WHERE id <> 64 AND emp_id = 110

Answer 2

You can do like this

// first find all the records for the employee with status as Active and make them Inactive.
    $query1 = mysql_query("select * from table_employee where emp_id = 110 and status = 'Active' ");
    if($query1 && mysql_num_rows($query1) > 0)
    {
         while(mysql_fetch_array($query1))
         {
              mysql_query("update table_employee set status = 'Inactive' where emp_id = 110");
         }
    }

// then make the record Active that you you want to
$query2 = mysql_query("update table_employee set status = 'Active' where emp_id = 110 and id = 64");

Answer 3

One thing you could try is to store the active id in a boolean value (if you're altering the table scheme). Then you could check the active by searching employee ID and boolean value true.
