General error: 20018 SQL Anywhere Error -267: COMMIT/ROLLBACK not allowed within atomic operation

Describe the bug

When making a CALL to the SQLAnywhere DB call mydatabase.ABCfunction(iforenames='Alun',isurname='Rowe',iemailaddress='alun@example.com',isite='ABC1231DDFFEERR') I am receiving the following error:

Select statements against the same database work fine as do read only calls.

To Reproduce

Steps to reproduce the behavior:

config/database.php

        'spaceman' => [
            'driver' => 'sqlsrv',
            'host' => env('DB_SM_HOST', 'localhost'),
            'port' => env('DB_SM_PORT', ''),
            'database' => env('DB_SM_DATABASE', ''),
            'username' => env('DB_SM_USERNAME', ''),
            'password' => env('DB_SM_PASSWORD', ''),
            'charset' => 'utf8',
            'prefix' => '',
        ],

.env

DB_SM_HOST=192.168.9.76
DB_SM_PORT=2646
DB_SM_DATABASE=mydatabase
DB_SM_USERNAME=user
DB_SM_PASSWORD=password

app\services\MyLibrary.php

$results = DB::connection('spaceman')->statement($querystring);

Illuminate\Database\QueryException SQLSTATE[HY000]: General error: 20018 SQL Anywhere Error -267: COMMIT/ROLLBACK not allowed within atomic operation [20018] (severity 16) [call mydatabase.ABCfunction(iforenames='Alun',isurname='Schtoop',iemailaddress='alun@example.com',isite='ABC1231DDFFEERR')] (SQL: call mydatabase.ABCfunction(iforenames='Alun',isurname='Schtoop',iemailaddress='alun@example.com',isite='ABC1231DDFFEERR'))

Expected behavior

return a single result with the id of the updated record

Please note using the SQLAnywhere PHP client library we get this no problem (but it is locked to PHP 7.1)
