Icon edb_first

Navigates to the first row in the cursor.

Syntax
edb_first(<CursorHandle>)

<CursorHandle> =

Handle of cursor returned by edb_execute function

Returns
TRUE if successful, and FALSE if there are any errors

Usage
The edb_first function navigates to the first row in a cursor, setting the BOF flag in the process.

Warning If the cursor state, retrievable via the edb_state function, is an insert state (EDB_INSERT_STATE) or update state (EDB_UPDATE_STATE), then this function will cause an automatic call to the edb_post function in order to force the cursor into a browse state (EDB_BROWSE_STATE).

<?php

// The following script connects to an ElevateDB
// Server and database, prepares and executes a
// direct table open, goes to the start of the cursor,
// and navigates to the end of the cursor
// by using the edb_eof() function to test when to
// stop navigating

$con = edb_connect("type=remote;charset=Ansi;address=127.0.0.1;"+
                   "uid=Administrator;pwd=EDBDefault;database=Test");
if (!$con)
  {
  die("Could not connect: " . edb_errmsg());
  }

$cmd = edb_prepare($con,"customer",EDB_COMMAND_TABLE);
$cursor = edb_execute($cmd);

edb_first($cursor);

while (!edb_eof($cursor)):
   edb_next($cursor);
endwhile;

echo edb_state($cursor);

edb_disconnect($con);
?>
