Laravel UUID from SQL Server Database Errors - sql-server

Question

I am having issues with a Laravel application using an existing database where MS SQL UUIDs are used. My application has a customer:
class Customer extends Model
{
protected $table = 'ERP.Customer';
public $timestamps = false;
protected $primaryKey = 'CustID';
protected $keyType = 'string';
protected $fillable = [
'CustID',
'SysRowID',
'CustNum',
'LegalName',
'ValidPayer',
'TerritoryID',
'Address1',
'Address2',
'Address3',
'City',
'State',
'Zip',
'Country',
'SalesRepCode',
'CurrencyCode',
'TermsCode',
'CreditHold',
'FaxNum',
'PhoneNum',
'CustomerType'
];
public function SalesTer()
{
return $this->belongsTo(SalesTer::class,'TerritoryID', 'TerritoryID');
}
public function Shipments()
{
return $this->hasMany(Shipment::class, 'CustNum', 'CustNum');
}
public function Equipments()
{
return $this->hasMany(Equipment::class,'CustNum', 'CustNum');
}
public function Customer_UD()
{
return $this->hasOne(Customer_UD::class,'ForeignSysRowID', 'SysRowID');
}
}
Which (in the native ERP application) has a UD table which end users can used to customise the Customer entity:
class Customer_UD extends Model
{
protected $table = 'ERP.Customer_UD';
protected $primaryKey = 'ForeignSysRowID';
public $timestamps = false;
public $incrementing = false;
protected $keyType = 'string';
protected $fillable = [
'ForeignSysRowID',
'MakesCans_c',
'MakesEnds_c',
'Industry_c'
];
public function Customer()
{
return $this->hasOne(Customer::class,'SysRowID', 'ForeignSysRowID');
}
}
CustomerController:
public function show($CustID)
{
if(Customer::find($CustID))
{
$Customer = Customer::find($CustID);
$Customer_UD = $Customer->Customer_UD()
->get();
$Shipments = $Customer->Shipments()
->where('Voided', '0')
->get();
$Equipments = $Customer->Equipments()
->with('Part') // load the Part too in a single query
->where('SNStatus', 'SHIPPED')
->get();
return view('Customer.show', ['NoCust' => '0'],
compact('Equipments', 'Customer','Shipments', 'Parts', 'Customer_UD'));
}
else
{
return view('Customer.show', ['NoCust' => '1']);
}
}
The Customer has (for whatever reason) a CustID (which people use to refer to the customer) a CustNum (which is not used outside of the database and a SysRowID. The SysRowID is used to link the Customer table with the Customer_UD table.
An example row from Customer_UD is:
My issue is that when trying to return the UD fields along with the Customer fields I get an error:
SQLSTATE[HY000]: General error: 20018 Incorrect syntax near ''.
[20018] (severity 15) [select * from [ERP].[Customer_UD] where [ERP].
[Customer_UD].[ForeignSysRowID] = '���_�X�O�Q׊3�^w' and [ERP].
[Customer_UD].[ForeignSysRowID] is not null]
I thought it was odd, so I commended out the Customer_UD lines in the CustomerController and simply tried to display the Customer UUID field in the show blade:
SysRowID: {{$Customer->SysRowID}}
I get nothing, no errors but no data. I created a controller and index blade for the Customer_UD model and can display all of the Customer_UD database fields apart from the UUID field.
I don't actually want to display the UUID fields - but do need to use them to build the relationships. Can anyone help point me in the right direction?

Answer 1

I found that adding:
'options' => [
PDO::DBLIB_ATTR_STRINGIFY_UNIQUEIDENTIFIER => true,
],
To the database configuration in config\database.php resolved the issue.
