SQL Column Name cannot be indexed by jquery

I am trying to read data from MySql with PHP and then send results with json_encode to client. I am then using jQuery script to read the results but unable to index the columns in the JSON because of the type of name given to the column has brackets in it COUNT(ID).

I am trying to learn several things at once, jQuery, SQL etc and think there must be a better/easier way?

I have made a SQL query to count the number of times a name appears in one of the columns. It returns a column name COUNT(ID)...

SQL query:

SELECT COUNT(ID), LocationName FROM myDB GROUP BY LocationName'

jQuery reading the JSON into arrays:

for(var i in data)
{
    getProfileName.push = data[i].ProfileName;
    getLocationCount.push = data[i].COUNT(ID)
}

I receive the JSON in my jQuery script, and it has the 2 columns LocationName and COUNT(ID)

But obviously I cannot use the index name of COUNT(ID) because of the brackets.

How do you reference names with brackets?

You need to give an alias for COUNT(ID) in your query, something like below:

SELECT COUNT(ID) as totalIdCount, LocationName FROM myDB GROUP BY LocationName
//------------------^you can chang alias name according to your comfort --------//

Now use this alias in jQuery

for(var i in data)
{
    getProfileName.push = data[i].ProfileName;
    getLocationCount.push = data[i].totalIdCount
}

Note:- you can try data[i]['COUNT(ID)'] directly in your jQuery code, but above is the standard practice.
