I have tested the snippet on MySQL 5 only.

SELECT SQL_COUNT ROWS *, tableName.id, tableName.someCol
FROM tableName
LIMIT 0,25;

SELECT SELECT FOUND_ROWS();

For example, say the above table tableName has a total of 100 rows, running the above queries one after another would first return a result set of 25 rows, then the second query would return 100, the total number of rows.

It may be interesting also to see if there is a performance difference between a 3 or a 2 query approach, as the MySQL manual only shows running the SQL_COUNT_ROWS * statement on it’s own, unlike with columns as I have done here.

My hunch is that 2 queries would be faster but maybe not for tables with millions of rows?

• the boolean FALSE itself
• the integer 0 (zero)
• the float 0.0 (zero)
• the empty string, and the string “0″
• an array with zero elements
• an object with zero member variables (PHP 4 only)
• the special type NULL (including unset variables)
• SimpleXML objects created from empty tags

Every other value is considered TRUE (including any resource).

This example has been tested with Ext Js 4

var combo = Ext.create('Ext.form.field.ComboBox', {
  ...
  listeners: {
   'select':function(selected){ alert(selected.value); }
  }
  ...
});

Make sure your Panel IDs are unique.

In my case, I had 2 form panels both with the same ID that I was trying to render.
