使用PDO在php中使用Mac运行MS SQL Server存储过程

Question

I am trying to execute a stored procedure in an instance of ms sql server, using php from a mac.

I have recently bought a mac book pro and seem to be having real problems achieving this.

I now have a connection established, which I know is working as if I change the password I get the message:

"Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[01002] Adaptive Server connection failed (severity 9)' in /Users/davidwhitwell/Sites/test/connect.php on line 6"

Correcting the password does not give me the error.

The script I am trying to run is:

    $sql = $pdo->prepare("CALL [finance].[get_all_company_names]");
    $sql->execute();
    $results = $sql->fetchAll();
    var_dump($results);

The result returns an empty array. I know data exists and that the correct permissions are in place to execute the procedure as I can do this directly with sql server management studio.

Since you mentioned that you are not able to retrieve any data, even with a simple select query, I suggest adding some error handling to your script.

First, I would add some exception handling to your general pdo object.

$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

This will throw an exception when your query fails. Then wrap your execution in a try/catch statement

try {
  $sql = $pdo->prepare("CALL [finance].[get_all_company_names]");
  $sql->execute();
  $results = $sql->fetchAll();
  var_dump($results);
} catch (PDOException $e) {
  echo 'An error occurred: ' . $e->getMessage();
}

The sql and the pdo objects you created also have a method called errorInfo, that will sometimes display an error.

if($sql->execute()) {
  $results = $sql->fetchAll();
}
else {
  $error_info = $dbh->errorInfo();
  print_r($error_info);
}

Some good resources include these page

• PDO Error Handling: http://www.php.net/manual/en/pdo.error-handling.php
• PDOStatement::errorinfo: http://www.php.net/pdostatement.errorinfo

EDIT

I believe the ultimate is that stored procedures in MS SQL are called using EXEC

  $sql = $pdo->prepare("EXEC [finance].[get_all_company_names]");
