Hm, I was found that problem occurs not for All PDO drivers. For sqlite:
- all fine, but for pgsql:
problem was present.
(Sorry, do not have time for continue analyze, I will fix it for me by implement alternative approach)

I will try to continue :)
source code of validator: https://github.com/zendframework/zend-validator/blob/2868a943818de387c1747f2ca966d4914e18bebb/src/Db/AbstractDb.php#L315-L325
protected function query($value)
{
$sql = new Sql($this->getAdapter());
$select = $this->getSelect();
$statement = $sql->prepareStatementForSqlObject($select);
$parameters = $statement->getParameterContainer();
$parameters['where1'] = $value;
$result = $statement->execute()
source code of https://github.com/zendframework/zend-db/blob/b1c79192c76b817062c1fa4e81ef2dcf1afea73e/src/Sql/AbstractSql.php#L136
if (! isset($this->instanceParameterIndex[$namedParameterPrefix])) {
$this->instanceParameterIndex[$namedParameterPrefix] = 1;
}
$expressionParamIndex = &$this->instanceParameterIndex[$namedParameterPrefix];
.....
$name = $namedParameterPrefix . $expressionParamIndex++;
so, for Select
Object we have ever-increased number postfix for named parameter markers: where1
, where2
, etc...
But for sqlite is Ok, because Zend\Db\Sql\Platform\Platform
has Select decorator for sqlite, and Platform
object was re-instantiated for each 'validation call', and in this case we have that $this->instanceParameterIndex
reset each time
:)
I am not sure that it is must be fixed on zend-db
side, looks like better implement some alternative approach for validator :)
