使用PostgreSql和PHP的INSERT语句中的错误

Question

I'm using postgresql, with php and pdo. I'm getting a error and I dont know what I'm doing wrong.

• My environment is:

PostgreSQL 9.3.6

Ubuntu 14.04.2 LTS

PHP 5.6.7

Apache/2.4.12 (Ubuntu)

The table which I'm using is this:

-- Table: acesso.usuario

-- DROP TABLE acesso.usuario;

CREATE TABLE acesso.usuario
(
  usuarioidentificador serial NOT NULL,
  usuariopessoafisicaidentificador integer,
  usuarionome character varying(30) NOT NULL,
  usuarionomecompleto character varying(90) NOT NULL,
  usuariodescricao text,
  usuariosenha character varying(32) NOT NULL,
  usuariosenhaalterar bit(1) NOT NULL,
  usuariosituacao bit(1) NOT NULL
)
WITH (
  OIDS=FALSE
);

If I execute this at pgadmin3

INSERT INTO acesso.usuario(
            usuariopessoafisicaidentificador, usuarionome, 
            usuarionomecompleto, usuariodescricao, usuariosenha, usuariosenhaalterar, 
            usuariosituacao)
    VALUES (null, '', '', 
            null, '', '1', '1'
            );

I got this Query returned successfully: one row affected, 82 ms execution time.

So I'm trying the same with PHP:

try {
            $query ="
            INSERT INTO acesso.usuario(
            usuariopessoafisicaidentificador, usuarionome, 
            usuarionomecompleto, usuariodescricao, usuariosenha, usuariosenhaalterar, 
            usuariosituacao)
    VALUES (null, '', '', 
            null, '', '1', '1'
            );
";

            $this->statement = $query;
            $conn = $this->getConnection();

            $query = $conn->prepare($this->statement, [\PDO::ATTR_CURSOR => \PDO::CURSOR_SCROLL]);

            $result = $query->execute();

        } catch (\Exception $e) {
            echo $e->getMessage() . "  <br> " . $e->getCode();

            var_dump($query);
            die();
            return false;
        }

I'm getting this output:

SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "INSERT" LINE 2: INSERT INTO acesso.usuario( ^ 42601object(PDOStatement)#14 (1) { ["queryString"]=> string(291) " INSERT INTO acesso.usuario( usuariopessoafisicaidentificador, usuarionome, usuarionomecompleto, usuariodescricao, usuariosenha, usuariosenhaalterar, usuariosituacao) VALUES (null, '', '', null, '', '1', '1' ); " }

I'm trying to find out what is happening.

Do you know it?

Thank you anyway.

Answer 1

As the query is an INSERT (as opposed to a SELECT), it can't be mapped onto a cursor. The problem is in the attributes passed to prepare :

 [\PDO::ATTR_CURSOR => \PDO::CURSOR_SCROLL]

Internally, PDO generates a query starting like this for postgres:

DECLARE pdo_crsr_00000001 SCROLL CURSOR WITH HOLD FOR
  INSERT INTO acesso.usuario(...

and as documented in DECLARE , the query that follows must be a SELECT or VALUES command , which is why the parser yields a syntax error when it finds an INSERT there instead.

The solution is simply to remove the second argument:

$query = $conn->prepare($this->statement);
