No result when executing multiple statements with PHP ODBC - php

Question

I have a problem with executing multiple queries at once with ODBC in PHP.
My code:
$createRowQ = "
declare #myid uniqueidentifier;
set #myid = NEWID();
insert into tps_attachment_data values (#myid, '');
print #myid;
";
$createRow = odbc_prepare($connection, $createRowQ);
odbc_execute($createRow);
$result = odbc_result_all($createRow);
Result:
Variable $result is empty and PHP is giving me this warning with SQL error:
PHP Warning: odbc_execute(): SQL error: [Microsoft][ODBC Driver 13
for SQL Server][SQL Server]46023075-414D-4FF2-87D5-B3B462FE3AF8, SQL
state 01000 in SQLExecute in C:\inetpub\wwwroot\receiver.php on line
656
I think that the problem is in calling multiple statements at once, but I need to declare my ID to be able to print it. Any help would be appreciated.
SQL statement works just fine when I execute it in Management Studio.
PHP version is 7.3.1.

Answer 1

I'm able to reproduce this warning, so the following answer provides a possible solution for this issue. The necessary changes are:
Use SET NOCOUNT ON as first line in your statement to prevent SQL Server from passing the count of rows affected as part of the result set.
Use SELECT #myid AS MyID instead of PRINT #myid to return the generated unique identifier as a result set.
Use odbc_exec() to prepare and execute an SQL statement.
PHP:
<?php
...
$createRowQ = "
SET NOCOUNT ON;
DECLARE #myid uniqueidentifier;
SET #myid = NEWID();
INSERT INTO tps_attachment_data VALUES (#myid, '');
SELECT #myid AS MyID;
--PRINT #myid
";
$result = odbc_exec($connection, $createRowQ);
$line = odbc_fetch_array($result);
echo $line["MyID"];
...
?>
