如何使用 function 执行 mssql 查询？

Question

I want to run a mssql query that has a part of the user defined function. This is my code:

$connection = $this->em->getConnection();

$sql = 'select * from ssm.table where ip = dbo.fn_ConvertIpAddressToBinary(\'192.168.0.1\')';

$result = $connection->executeQuery($sql);
$results = $result->fetchAll();

var_dump($results);

However, I get a blank response. If you set the request without function, everything works fine. This query works fine in sql query analyzer.

What can I do wrong?

Answer 1

try rewrite as: $sql = "select * from ssm.table where ip = dbo.fn_ConvertIpAddressToBinary('192.168.0.1')";
