and here is the method getPessoaTable()
public function getPessoaTable()
{
if (!$this->pessoaTable) {
$sm = $this->getServiceLocator();
$this->pessoaTable = $sm->get('Pessoa\Model\PessoaTable');
}
return $this->pessoaTable;
}
I have configured pdo_firebird.so in php. And it shows up on phpinfo()

Answer 1

The important part of the error is: "Table unknown pessoa". You are selecting from a table pessoa, no such table exists according to Firebird. The fact that pessoa is lower case in the error message shows you are using quoted identifiers. Quoted identifiers are case sensitive in Firebird. Unquoted identifiers are upper cased to make them case insensitive.
So this error either means the table really doesn't exist, or - as you use quoted identifiers - the table name is actually PESSOA. The rules Firebird uses for quoted/unquoted identifiers will make SELECT ... FROM pessoa work, but SELECT ... FROM "pessoa" fail.
I don't know PDO, so I can't give a PDO specific help, but I hope this narrows it down for you.
