Question

I am using the google chart framework based on a data in database…

I need to generate an output like:

([
  ['Year',  'ON',   'OFF',  'X1',   'X2'],
  ['Jan/12',    2,  5,      10,         9],
  ['Fev/12',    5,  10,     54,         10],
  ['Mar/12',    10, 36,     15,         10]
]);

Note that the last line do not have a comma. My code looks like:

([
  ['Year',  'ON',   'OF',   'X1',   'X1'],
    <%
        WHILE NOT DB.EOF
        ON= DB("ON")
        OFF= DB("OFF")
        X1= DB("X1")
        X2= DB("X2")
    %>
        ['<% Response.Write Month %>/<% Response.Write Year %>',    <% Response.Write ON %>, <% Response.Write OFF %>, <% Response.Write X1 %>, <% Response.Write X2 %>,
    <%
        DB.MOVENEXT
        WEND
    %>
]);

My question: How can I check when the loop come to the last line, instead of put the comma, put just nothing?

Thanks!

AnthonyWJones’s answer seems ok for me, but you could also ask inside loop if after move next you’re not at EOF then you write “,”

([ 
    ['Year',  'ON',   'OFF',   'X1',   'X2']
    <% Do While Not DB.EOF %>
        [
         '<%= Month %>/<%= Year %>', 
         <%= DB("ON") %>, 
         <%= DB("OFF") %>, 
         <%= DB("X1") %>, 
         <%= DB("X2") %>
        ]
        <%
        DB.MoveNext
        %>
        <% If Not DB.EOF Then %>
            ,
        <% End If %>
    <% Loop %>
]);
