error when using createEntityTables - magento

Question

I get this error when I include
$installer->createEntityTables( $this->getTable('red/red') );
I am using enterprise 1.11
I have also seen alternative to that is type every thing which is really time consuming. Could someone please tell me who to make this function work.

Answer 1

This is a problem with an error being triggered when it shouldn't be. Long story short, MySQL doesn't support DDL transactions, and in the course of the method DDL routines are being found in the SQL and an error is thrown.
The easy answer is to comment out this line:
lib/Varien/Db/Adapter/PDO/Mysql.php
protected function _checkDdlTransaction($sql)
{
if (is_string($sql) && $this->getTransactionLevel() > 0) {
$startSql = strtolower(substr(ltrim($sql), 0, 3));
if (in_array($startSql, $this->_ddlRoutines)) {
// comment this out: trigger_error(Varien_Db_Adapter_Interface::ERROR_DDL_MESSAGE, E_USER_ERROR);
}
}
}
Doing so allows your module to install. Obviously hacking a core file is a terrible idea. You should extend the method or allow the SQL to run, and then translate the generated SQL into the Magento MySQL API, as seen in core sql setup scripts. The latter is a major pain.. the better idea would be to extend the method.
