dbgrid saving data after edit

Hi!

I build a small application using a dbgrid, query, database and datasource
components.

The data is showed in the grid and I can edit values on each row, but the
data was not saved to database.

I put in the form a button with the code below in onclick event:
function Button1Click($sender, $params)
{
$this->Query1->Post();
}
But when I click in this button I receive the messages:
Warning: reset() [function.reset]: Passed variable is not an array or object
in C:\program files\CodeGear\delphi for php\1.0\vcl\dbtables.inc.php on line
815

Warning: Variable passed to each() is not an array or object in C:\program
files\CodeGear\delphi for php\1.0\vcl\dbtables.inc.php on line 816

Application raised an exception class ADODB_Exception with message 'mysql
error: [1064: You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near
'WHERE LIMIT 1' at line 1] in EXECUTE("SELECT * FROM WHERE LIMIT 1")'
Callstack #0 File: C:\tmp\dbgridtest\unit1.php Line: 48
....Other problem: I see only a fixed number of records. How to se more
records on a dbgrid object?Thanks!GR
