====== transCnt ======
~~NOTOC~~
<WRAP right box>
== Syntax ==
  int ADOconnection::transCnt
</WRAP>
===== Description =====
The value of ''$db->transCnt'' returns the current transaction nesting level. If no transaction has been started, the value is zero. 

For **//granular//** transaction handling:
  * The value is always 1 when a transaction has been started, as nested transactions are not permitted.

For **//smart//** transaction handling:
  * The value indicates the nesting level of smart transactions. You should not modify the value of this variable manually, as this will likely cause a transaction scope failure. 

You can check the value of transCnt to see if a transaction has been started. This is useful in, for example, loadable classes where the start point of a transaction might be in a different procedure.
 
===== Usage =====
<code php>

if ($db->transCnt == 0)
    $db->startTrans();

/*
* transCnt is now 1 Do some work
*/
$db->startTrans();

/*
* transCnt is now 2
*/
$db->execute('some insert statement...');


/*
* Because the transCnt > 1, the completeTrans is ignored 
*/
$db->completeTrans();

/*
* transCnt is now 0, complete the transaction
*/
$db->completeTrans()
